All questions

Question 1

In a long-term care facility, an 82-year-old female has new bruises on her upper arms and appears anxious when her adult son (caregiver) enters the room. The son is irritated, answers for her, and says she is "clumsy." Which statement by the client suggests a need for immediate intervention?

  1. "My son gets frustrated because I forget things."
  2. "Please don't tell him I said anything; he gets angry when we're alone." (correct answer)
  3. "I don't like to bother the staff with my problems."
  4. "I bruise easily since I started my blood thinner."

Explanation: This question tests recognition of elder abuse indicators and statements requiring immediate intervention. Key risk factors include physical injuries, caregiver control, victim anxiety, and the caregiver answering for the client. The correct answer (B) - "Please don't tell him I said anything; he gets angry when we're alone" - requires immediate intervention because it directly indicates fear of the caregiver and confirms abuse is occurring when they're alone. Option A (frustration) suggests caregiver stress but not abuse, C (not wanting to bother staff) shows passivity but not immediate danger, and D (bruising from medication) provides a plausible alternative explanation. The critical principle is that expressions of fear toward caregivers, especially with requests for secrecy, confirm abuse and require immediate protective action. When assessing elder abuse risk, prioritize statements that reveal fear of caregivers or confirm private abuse over general signs of caregiver stress or medical explanations.

Question 2

In an outpatient clinic, a 42-year-old male with a history of depression reports, "Nothing is going to get better," and recently lost his job and separated from his partner. Which statement by the client suggests a need for immediate intervention?

  1. "I've been sleeping more than usual lately."
  2. "I stopped taking my antidepressant because it wasn't helping."
  3. "I've been giving away my things because I won't need them soon." (correct answer)
  4. "I don't feel like talking to my friends anymore."

Explanation: This question tests recognition of suicide and violence risk, specifically identifying verbal cues that indicate imminent suicide risk. Key psychosocial indicators include hopelessness, recent losses, and behavioral changes that suggest preparation for suicide. The correct answer (C) - giving away possessions because they won't be needed - is the highest priority because it indicates active suicide planning and preparation, suggesting the client has made a decision and is taking concrete steps. Option A (increased sleep) and D (social withdrawal) are concerning depression symptoms but don't indicate immediate risk, while B (stopping medication) is problematic but doesn't suggest active planning. The critical principle is that specific suicide planning behaviors (giving away possessions, saying goodbyes, getting affairs in order) require immediate intervention over general depression symptoms. When assessing suicide risk, always prioritize statements or behaviors that indicate a specific plan, method, or timeline over general expressions of distress.

Question 3

At a school-based clinic, a 15-year-old male who recently stopped participating in sports reports being bullied online. He avoids friends, has declining grades, and states, "Soon none of this will matter." Which finding should be REPORTED immediately to the RN?

  1. Declining grades over the last marking period.
  2. Withdrawal from sports and activities he used to enjoy.
  3. The statement, "Soon none of this will matter." (correct answer)
  4. Reports of being bullied online.

Explanation: This question tests recognition of adolescent suicide risk with multiple risk factors present. Key indicators include cyberbullying, social withdrawal, academic decline, and verbal expressions suggesting finality. The correct answer (C) - "Soon none of this will matter" - requires immediate reporting because it expresses a sense of finality and suggests the teen may be contemplating suicide as a solution to current problems. Option A (declining grades) and B (activity withdrawal) are concerning but common with depression, while D (cyberbullying) is a risk factor but not an immediate warning sign like option C. The critical principle is that statements suggesting finality or resolution through implied action take precedence over behavioral changes or environmental stressors alone. When assessing adolescent suicide risk, prioritize verbal expressions that suggest endings or finality, as these often precede suicide attempts in teens experiencing multiple stressors.

Question 4

On a medical-surgical unit, a 67-year-old male admitted for heart failure has a history of depression. Today he is unusually calm, refuses dinner, and states, "You won't have to worry about me much longer." Which behavior indicates the HIGHEST RISK for suicide?

  1. Refusing to eat dinner and turning toward the wall.
  2. Requesting to speak with the chaplain about guilt.
  3. Asking for all of his home medications to be brought to the hospital room.
  4. Saying, "You won't have to worry about me much longer," while appearing unusually calm. (correct answer)

Explanation: This question tests recognition of acute suicide risk in hospitalized patients with depression history. Key indicators include sudden mood changes, final statements, and behaviors suggesting resolution or planning. The correct answer (D) - stating "You won't have to worry about me much longer" while appearing unusually calm - indicates the highest risk because the combination of a veiled suicide statement with sudden calmness suggests the patient has made a suicide decision and feels relief. Option A (refusing food/withdrawal) shows depression but not acute risk, B (spiritual support) is actually protective, and C (requesting medications) could be concerning but lacks the finality of option D. The principle is that sudden calmness in a depressed patient, especially with statements suggesting finality, indicates extreme risk as they may have decided on suicide. When assessing hospitalized patients, be alert for sudden mood improvements or calmness combined with final-sounding statements, as this often precedes suicide attempts.

Question 5

The nurse is caring for an adult client with a history of post-traumatic stress disorder (PTSD) who is becoming increasingly agitated in the hospital dayroom. The client is pacing rapidly, clenching their fists, and speaking in a loud, aggressive tone to other clients.

Which action should the nurse take first to manage the care of this agitated client?

  1. Instruct the UAP to place the client in a physical restraint.
  2. Request a prescription for a STAT dose of an intramuscular sedative.
  3. Attempt to de-escalate the situation by speaking calmly and moving the client to a quieter area. (correct answer)
  4. Notify the hospital security team to remove the client from the dayroom immediately.

Explanation: The LPN/VN must apply the principle of least restrictive intervention when managing an agitated client. De-escalation techniques — using a calm, quiet voice, reducing environmental stimulation, and moving the client away from the crowded dayroom that may be triggering the agitation — are the appropriate first-line response and must be attempted before any restrictive measures. Placing the client in a physical restraint (A) is a last resort that requires a specific order and can significantly worsen agitation, particularly in a client with PTSD for whom being physically restrained may trigger traumatic memories. Requesting a sedative (B) requires a PHCP prescription and cannot be the first independent nursing action. Calling security (D) is appropriate if de-escalation fails and the client poses an imminent physical threat — not as the first response to verbal agitation.

Question 6

During a routine admission interview at a community clinic, a client tells the nurse, 'Sometimes I feel like life isn't worth living anymore, and I've been thinking about how I would do it.'

What is the most appropriate and direct response for the nurse to make?

  1. "Are you currently having thoughts of hurting or killing yourself?" (correct answer)
  2. "You shouldn't feel that way; you have so much to live for."
  3. "Let's talk about something more positive to help improve your mood."
  4. "I will need to tell your family about these feelings immediately."

Explanation: When a client makes statements that suggest suicidal ideation, the nurse must use direct, clear therapeutic communication to assess the immediate level of risk. Asking directly whether the client is having thoughts of hurting or killing themselves is both clinically appropriate and evidence-based — research consistently shows that asking directly about suicide does not increase risk and is essential for accurate crisis assessment. Choice B dismisses and invalidates the client's feelings, which can close communication and increase isolation. Choice C changes the subject and is an avoidant response that fails to address a potential safety issue. Choice D is premature — notifying the family without first assessing the client's actual risk level, exploring their wishes, and following established protocols may violate confidentiality and disrupt the therapeutic relationship before it has been established.

Question 7

A nurse is caring for a client who was recently admitted after a violent altercation at home. The client tells the nurse, 'As soon as I get out of here, I'm going to make sure my neighbor regrets calling the police on me.'

Which legal and ethical responsibility should the nurse prioritize in this situation?

  1. Maintain the client's absolute confidentiality regarding this statement.
  2. Follow the facility policy for reporting the threat to the supervisor and the authorities. (correct answer)
  3. Document the statement in the chart but wait until discharge to take action.
  4. Ask the client's family if they think the neighbor is actually in any danger.

Explanation: Nurses have a legal and ethical duty to report specific, credible threats of harm to identifiable third parties. When a client makes a statement indicating intent to harm a specific individual, confidentiality is superseded by the duty to protect. This principle — codified in law following the Tarasoff decision and reflected in most state nurse practice acts — requires the nurse to report the threat to the appropriate parties according to facility policy so that steps can be taken to protect the potential victim. Maintaining absolute confidentiality (A) is incorrect in situations involving imminent threat to others — confidentiality has legally recognized limits. Waiting until discharge (C) creates an unacceptable delay that could allow harm to occur. Delegating the risk assessment to the family (D) is inappropriate — the nurse cannot transfer this professional and legal responsibility.

Question 8

The nurse is reinforcing discharge teaching with the family of a client who is being discharged after a suicide attempt. The nurse is discussing environmental safety measures for the home.

Which instruction should the nurse include in the reinforcement?

  1. Keep all firearms and medications in a locked cabinet with the keys hidden. (correct answer)
  2. Allow the client to have as much privacy as possible to help them recover.
  3. Avoid talking about suicide with the client so you don't give them any ideas.
  4. Encourage the client to spend most of their time alone to reflect on their life.

Explanation: Means restriction — limiting access to lethal instruments — is one of the most evidence-based strategies for suicide prevention. Securing firearms and medications in a locked cabinet with keys inaccessible to the client reduces impulsive access during a crisis moment. Note that the clinical gold standard is complete removal of firearms from the home; when removal is not possible or refused, locked storage is the minimum acceptable measure. Allowing extensive unsupervised privacy (B) increases risk by removing protective supervision during a high-risk period. The instruction to avoid discussing suicide (C) is a common but incorrect myth — research shows that talking openly and compassionately about suicide does not increase risk and often reduces it by reducing shame and increasing help-seeking. Encouraging time alone (D) promotes social isolation, which is a known risk factor for both depression and completed suicide.

Question 9

Client: 19-year-old male student. Situation: Brought to the emergency department by a roommate after being found sitting on the floor with a bottle of pills. History: Recent breakup with a partner; failing grades in college. Assessment: The client is quiet, avoids eye contact, and has a flat affect. He states, "I just can't do this anymore. It's too much."

Which information from the client's history is the most significant indicator of a potential crisis?

  1. The client's age of 19 years.
  2. The recent breakup and failing grades in college. (correct answer)
  3. The client's flat affect and avoidance of eye contact.
  4. The client's presence in the emergency department.

Explanation: A crisis occurs when a person's usual coping mechanisms are overwhelmed by stressors. The recent breakup and concurrent academic failure represent multiple significant psychosocial losses happening simultaneously — relationship loss, identity disruption, and failure of a key life goal — which together can rapidly exceed a young person's coping capacity and precipitate a crisis. These specific stressors also correspond to well-established risk factors for suicide in young adults. Age 19 (A) is a demographic factor associated with elevated general risk but does not by itself indicate a crisis. Flat affect and avoidance of eye contact (C) are important current behavioral cues but describe the client's current state rather than the historical factors that precipitated the crisis. Presence in the ED (D) confirms a crisis has occurred but is itself a consequence of the precipitating stressors, not the indicator.

Question 10

Client: 19-year-old male student. Situation: Brought to the emergency department by a roommate after being found sitting on the floor with a bottle of pills. History: Recent breakup with a partner; failing grades in college. Assessment: The client is quiet, avoids eye contact, and has a flat affect. He states, "I just can't do this anymore. It's too much."

Based on the client's statement and current situation, which nursing hypothesis is the priority for the nurse's clinical judgment?

  1. Risk for self-directed violence related to feelings of hopelessness. (correct answer)
  2. Compromised family coping related to the client's academic failure.
  3. Deficient knowledge regarding college counseling resources.
  4. Social isolation related to the recent relationship breakup.

Explanation: Safety is always the clinical priority. The client has been found with a bottle of pills after expressing that he 'can't do this anymore' — this constitutes an immediate, life-threatening presentation. Risk for self-directed violence is the most urgent hypothesis because it carries the potential for irreversible harm and must be addressed before any other psychosocial or educational concerns. Compromised family coping (B) may be a relevant secondary concern but is not the immediate priority. Deficient knowledge about counseling resources (C) is an appropriate long-term planning hypothesis but does not address the acute safety crisis. Social isolation (D) is a contributing factor and a valid hypothesis for the care plan, but the immediate risk to the client's life takes absolute precedence over relationship-focused hypotheses.

Question 11

Client: 19-year-old male student. Situation: Brought to the emergency department by a roommate after being found sitting on the floor with a bottle of pills. History: Recent breakup with a partner; failing grades in college. Assessment: The client is quiet, avoids eye contact, and has a flat affect. He states, "I just can't do this anymore. It's too much."

Which immediate action should the nurse include in the client's plan of care to ensure safety?

  1. Assign a staff member to provide one-to-one continuous observation. (correct answer)
  2. Provide the client with a list of outpatient support groups for students.
  3. Encourage the client to call their parents to discuss their feelings.
  4. Allow the client to keep their personal belongings to maintain autonomy.

Explanation: For a client at high risk for suicide — found with a lethal means and expressing hopelessness — one-to-one continuous observation by a staff member is the most essential immediate safety intervention. This ensures constant surveillance and the ability to physically intervene if the client attempts self-harm. The observer must maintain close, uninterrupted proximity at all times, including during bathroom use. Providing a list of outpatient support groups (B) is a discharge planning consideration, not an immediate crisis intervention. Encouraging a phone call to parents (C) may be appropriate as a supportive measure but does not constitute a safety intervention for an actively suicidal client. Allowing the client to retain personal belongings (D) is incorrect and potentially dangerous — the client's belongings must be searched and potentially lethal items removed per facility safety protocols.

Question 12

Client: 19-year-old male student. Situation: Brought to the emergency department by a roommate after being found sitting on the floor with a bottle of pills. History: Recent breakup with a partner; failing grades in college. Assessment: The client is quiet, avoids eye contact, and has a flat affect. He states, "I just can't do this anymore. It's too much."

The nurse is searching the client's belongings according to facility policy. The client becomes angry and yells, "You have no right to touch my things!" What is the most appropriate response by the nurse?

  1. "I am sorry, but you are being difficult, and I have to do my job."
  2. "We search everyone's belongings to make sure there is nothing that could harm you."
  3. "If you don't stop yelling, I will have to call security to restrain you."
  4. "I understand this is frustrating, but it is necessary for your safety here." (correct answer)

Explanation: Therapeutic communication for an angry client requires acknowledging their feelings without abandoning the necessary safety intervention. Choice D validates the client's emotional experience ('I understand this is frustrating') while clearly maintaining the boundary that the safety search will proceed ('it is necessary for your safety'). This approach is most likely to de-escalate the anger while preserving the therapeutic relationship. Choice A is dismissive and labels the client's behavior negatively, which escalates rather than de-escalates. Choice B is factually accurate but lacks the emotional acknowledgment that is the more complete therapeutic response — explaining the policy without validating the client's feelings misses an important opportunity. Choice C is a threat that introduces coercion into the interaction, which is counterproductive for a distressed client and is not the appropriate first response to verbal anger.

Question 13

A nurse is performing a home health visit for an 85-year-old client who lives with an adult grandchild. The nurse notes the client has several unexplained bruises on their upper arms and appears unusually fearful when the grandchild enters the room.

Which action should the nurse take first?

  1. Ask the grandchild to explain how the bruises occurred.
  2. Document the findings and return in one week to see if more bruises appear.
  3. Interview the client privately to collect more data regarding the bruises. (correct answer)
  4. Advise the client to move to a long-term care facility for their safety.

Explanation: When the nurse suspects elder abuse or neglect, the priority first action is to interview the client privately — away from the suspected abuser — to allow the client to speak freely without fear of retaliation or consequences. The combination of unexplained bruises in a pattern suggestive of gripping (upper arms) and visible fear in the presence of the grandchild are significant warning signs that warrant careful, confidential data collection. Confronting the grandchild first (A) alerts the potential abuser before the nurse has gathered the client's account and may escalate danger for the client. Waiting a week to observe (B) delays necessary action and leaves a vulnerable adult at risk. Advising immediate placement in long-term care (D) is premature before completing the assessment and following the mandatory reporting process — this decision involves multiple parties and cannot be made unilaterally by the nurse during the initial visit.

Question 14

A nurse is preparing to delegate tasks to a UAP for a client who is on 'Suicide Precautions' with one-to-one observation.

Which instruction by the nurse provides the most effective direction for the UAP?

  1. "Keep an eye on the client and let me know if they try to do anything bad."
  2. "Check on the client every 15 minutes and record their activity in the log."
  3. "Make sure the client stays in their room and doesn't talk to anyone else."
  4. "You must remain within arm's length of the client at all times, including in the bathroom." (correct answer)

Explanation: Right Direction and Communication in delegation requires instructions that are specific, measurable, and clinically actionable. 'Remain within arm's length of the client at all times, including in the bathroom' is the operationally precise definition of one-to-one observation — it tells the UAP exactly how close to remain, removes any ambiguity about unsupervised time, and specifically addresses the highest-risk moments (bathroom, private moments) when a client at suicide risk is most vulnerable. Choice A is vague and does not define proximity or what constitutes reportable behavior. Choice C focuses on isolation (staying in the room, no talking) which is not the goal of one-to-one observation and could worsen the client's mental state. Choice B describes 15-minute checks, which is a lower level of surveillance than one-to-one observation — periodic checks are used for lower-acuity monitoring and are entirely insufficient for a client on suicide precautions.

Question 15

The nurse is collecting data for a client who reports being in a 'physically and emotionally abusive' relationship. The client states, 'I want to leave, but I'm afraid of what they will do to me if I try.'

Which intervention is the priority for the nurse to include in the plan of care?

  1. Encourage the client to confront the abuser tonight.
  2. Assist the client in developing a personal safety and escape plan. (correct answer)
  3. Provide the client with literature on how to improve the relationship.
  4. Tell the client that they are overreacting to the situation.

Explanation: For a client in an abusive relationship, the priority intervention is safety planning. Helping the client develop a personal safety and escape plan provides concrete, actionable steps they can take — identifying a safe place to go, gathering important documents, establishing a code word with trusted contacts — without requiring the client to act immediately in ways that could increase their danger. The client's expressed fear about what the abuser 'will do' if they try to leave reflects a well-founded concern; leaving an abusive relationship is statistically the most dangerous time for victims of domestic violence. Encouraging confrontation tonight (A) creates immediate, severe danger. Providing relationship improvement literature (C) misframes the situation as a mutual problem and implicitly places responsibility on the victim. Telling the client they are overreacting (D) is dismissive, harmful, and directly contradicts the client's reality.

Question 16

A client with a known history of impulsive behavior and low frustration tolerance is waiting for a scheduled procedure that has been delayed by two hours. The client is pacing, muttering to themselves, and glaring at the nursing station.

The nurse should identify these behaviors as cues for:

  1. An expected and normal reaction to a hospital delay.
  2. The client entering the escalation phase of potential violence. (correct answer)
  3. A need for the client to be discharged immediately.
  4. A sign that the client is ready for their procedure.

Explanation: The assault cycle describes a predictable progression from a triggering event through escalation, crisis (peak), de-escalation, and post-crisis phases. Pacing, muttering, and directed glaring are classic behavioral indicators of the escalation phase — the client's agitation is building but has not yet peaked. Recognizing this phase is clinically significant because the escalation phase is when de-escalation interventions are most effective; once a client reaches the crisis peak, options become more limited and restrictive. For a client with a known history of impulsive behavior and low frustration tolerance, these cues warrant immediate proactive engagement — acknowledging the delay, apologizing for the inconvenience, and offering a brief update — before the behavior escalates to verbal or physical aggression. These are not simply normal responses (A); the combination of nonverbal behavioral changes in a high-risk individual signals more than ordinary frustration. Discharge (C) and procedure readiness (D) are irrelevant to the safety concern.

Question 17

During a group therapy session, a client suddenly stands up and shouts, 'I've had enough of this! Everyone here is a liar!' and moves toward the door.

Which action should the nurse take to maintain a therapeutic environment?

  1. Physically block the door so the client cannot leave the session.
  2. Ask the other clients to tell the agitated client how they feel.
  3. Shout back at the client to sit down and show respect to the group.
  4. Allow the client to leave the room while a staff member follows at a safe distance. (correct answer)

Explanation: Allowing an agitated client to exit the high-stress environment while maintaining unobtrusive monitoring is the safest and most therapeutically appropriate response. The group setting has become the trigger — removing the client from this environment reduces stimulation and gives them space to de-escalate, while staff follow-up at a safe distance ensures monitoring and creates an opportunity for a private de-escalation conversation. Physically blocking the door (A) constitutes restraint — it is likely to dramatically escalate the agitation of a client who is already moving toward exit, and is not an appropriate first response to verbal anger without imminent physical threat. Shouting back (C) is a direct escalation that abandons therapeutic communication entirely. Asking other group members to respond to the agitated client (B) puts other potentially vulnerable clients in an unsafe interpersonal situation and is clinically inappropriate.

Question 18

A nurse is reinforcing teaching with a client who has a history of self-mutilation (cutting) as a coping mechanism for stress.

Which information should the nurse reinforce as a healthy alternative coping strategy?

  1. Try to ignore the feelings of stress until they eventually go away.
  2. Express your feelings by writing in a journal or calling a crisis support line when the urge arises. (correct answer)
  3. Keep all your feelings inside so you do not bother other people.
  4. Increase your caffeine intake to help you stay more alert and distracted.

Explanation: Healthy coping strategies for clients with a history of self-harm focus on emotional expression and connection — channeling distress into safe outlets rather than suppressing it or redirecting it through physical sensation. Journaling provides an immediate, private outlet for intense feelings, while contacting a crisis support line connects the client to professional support during high-risk moments. Together they address both the emotional and the help-seeking dimensions of crisis management. Ignoring feelings (A) and keeping feelings inside (C) are forms of emotional suppression that increase emotional pressure over time and are associated with worsening self-harm frequency. Caffeine (D) is a stimulant that increases anxiety and physiological arousal, which are triggers rather than relievers of self-harm urges. Note that techniques that substitute one form of physical pain or discomfort for another (such as snapping rubber bands) are no longer recommended by current clinical guidelines, as they reinforce the use of physical sensation to manage emotional distress — the same underlying mechanism as self-harm.

Question 19

The nurse is collecting data from a client who was brought to the emergency department after a suicide attempt by carbon monoxide poisoning. The client states, 'I didn't think it would be this hard to die.'

What is the nurse's priority during the initial data collection?

  1. Determine the client's spiritual and religious beliefs regarding death.
  2. Provide the client with information on local funeral homes.
  3. Ask the client why they are so unhappy with their life.
  4. Assess the client's physical stability and oxygenation status. (correct answer)

Explanation: Physiological stability always takes precedence over psychosocial assessment. Carbon monoxide poisoning is a medical emergency: CO binds to hemoglobin with approximately 200 times the affinity of oxygen, forming carboxyhemoglobin that cannot carry oxygen to tissues. The client may present with tissue hypoxia despite a normal-appearing pulse oximetry reading (standard pulse oximeters cannot distinguish carboxyhemoglobin from oxyhemoglobin). The nurse must immediately assess oxygenation status, ensure high-flow oxygen is being administered, and confirm the client's airway and hemodynamic stability before any psychosocial assessment. Spiritual beliefs (A) are appropriate for later holistic care planning but are not the physiological priority. Exploring unhappiness (C) is a psychosocial assessment that follows physical stabilization. Choice B is inappropriate under any clinical circumstances.

Question 20

A nurse in a behavioral health unit is caring for a 32-year-old client with a history of severe clinical depression who has been expressing feelings of worthlessness for the past week. During the morning rounds, the nurse notes that the client is suddenly smiling, neatly dressed, and states, 'Everything is finally going to be okay now. I have a plan to end all my problems.'

How should the nurse interpret this change in the client's behavior?

  1. The client is showing positive signs of recovery and improved mood.
  2. The client is experiencing a normal fluctuation in their emotional status.
  3. The client's risk for self-harm has significantly increased. (correct answer)
  4. The client is responding effectively to the newly prescribed antidepressant.

Explanation: A sudden, unexplained improvement in mood in a client with severe depression — particularly when accompanied by a statement about having a 'plan' — is a high-priority warning sign for imminent suicidal intent, not a sign of recovery. This phenomenon occurs because clients who have resolved their ambivalence and made a definitive decision to attempt suicide often experience a sense of calm and relief, which can appear superficially as improved mood. The reference to 'a plan to end all my problems' must be directly assessed as a possible suicide plan — the nurse's immediate next action is to ask directly: 'Can you tell me more about the plan you mentioned?' This is not an antidepressant response (D); antidepressants typically take 2 to 4 weeks to produce therapeutic effects, and early antidepressant initiation can paradoxically increase suicide risk by restoring energy before mood has fully stabilized.
