Vital Signs And Baseline ComparisonQuestion 1 of 20

A nurse in a long-term care facility is performing a morning assessment on an 82-year-old client with a history of well-controlled hypertension and chronic kidney disease. The client's baseline blood pressure over the last month has averaged 118/74 mmHg. During the assessment, the client appears slightly flushed and reports a persistent, dull headache that started an hour ago. The nurse measures the client's blood pressure and finds it is 152/94 mmHg.

Which action should the nurse take first?

Administer a prescribed PRN dose of acetaminophen for the headache.

Recheck the blood pressure in the opposite arm using a manual cuff.

Notify the primary health care provider (PHCP) of the change in status.

Encourage the client to increase oral fluid intake to 2,000 mL/day.

All questions

Question 1

Which action should the nurse take first?

Administer a prescribed PRN dose of acetaminophen for the headache.
Recheck the blood pressure in the opposite arm using a manual cuff.
Notify the primary health care provider (PHCP) of the change in status. (correct answer)
Encourage the client to increase oral fluid intake to 2,000 mL/day.

Explanation: The client's blood pressure has significantly increased from their specific baseline and they are symptomatic (headache and flushing). For an entry-level LPN/VN, the priority is to recognize this cue and report the change in condition to the PHCP to prevent potential complications. Administering acetaminophen (A) addresses a symptom but not the urgent hemodynamic change. Rechecking in the opposite arm (B) may be appropriate as a secondary verification step but delays reporting a clear, symptomatic clinical change. Increasing fluid intake (D) is not indicated for hypertension.

Question 2

A client who underwent a major abdominal surgery 6 hours ago is being monitored on the surgical unit. The client's baseline oxygen saturation (SpO2) on room air prior to surgery was 97%. During the current hourly check, the nurse observes that the client is increasingly drowsy, has shallow respirations, and the SpO2 has dropped to 91% on room air.

Which intervention to improve the client's respiratory status should the nurse perform first?

Request a prescription for a STAT portable chest X-ray.
Assist the client to a high-Fowler's position. (correct answer)
Perform a detailed focused neurological assessment.
Encourage the client to use the incentive spirometer every 2 hours.

Explanation: The nurse must prioritize immediate interventions for respiratory distress. Repositioning to a high-Fowler's position is an independent nursing action that facilitates maximal lung expansion and is the first step in addressing the acute drop in SpO2. A portable chest X-ray (A) is a dependent action requiring a prescription and does not directly improve oxygenation. A detailed neurological assessment (C) is not the priority when there is an acute respiratory change requiring immediate intervention. Incentive spirometry (D) is an appropriate preventive measure post-operatively but requires the client to be cooperative and alert; it is not effective as a first-line response to an acute SpO2 drop in a drowsy client and does not address the immediate problem.

Question 3

The nurse is collecting vital signs for a client with a history of heart failure and atrial fibrillation who is reporting mild shortness of breath. The client's baseline heart rate is typically between 72 and 80 beats per minute (bpm) and regular. During the assessment, the nurse finds the client's radial pulse is 110 bpm and feels irregular.

Which action should the nurse take next?

Document the heart rate as a normal variation related to the client's activity.
Delegate the re-measurement of the heart rate to an unlicensed assistive personnel (UAP).
Manually palpate the client's apical pulse for one full minute. (correct answer)
Administer the scheduled morning dose of the client's cardiac medication.

Explanation: When a client's heart rate changes significantly in rate or rhythm from their established baseline, the LPN/VN must perform focused data collection. An apical pulse assessed for a full minute provides the most accurate characterization of the heart's rate and rhythm in this scenario and is essential before any further action. Documenting as a normal variation (A) is incorrect; 110 bpm and irregular is a meaningful deviation from this client's baseline. Delegating re-measurement to a UAP (B) is inappropriate when the nurse has already identified an abnormal and potentially dangerous change requiring nursing assessment. Administering scheduled cardiac medication (D) could be contraindicated depending on the rhythm and should not precede assessment.

Question 4

An adult client has just returned to the clinical unit following a colonoscopy performed under moderate sedation. The client's baseline respiratory rate recorded during pre-admission was 16 breaths/min. During the first post-procedure assessment, the nurse notes the client is difficult to arouse and has a respiratory rate of 8 breaths/min.

Which is the priority nursing hypothesis regarding the client's status?

The client is experiencing a typical and expected recovery phase of sedation.
The client is at high risk for respiratory depression related to medication. (correct answer)
The client has developed a fluid volume deficit from the pre-procedure prep.
The client is experiencing acute pain and is guarding their abdominal muscles.

Explanation: A respiratory rate of 8 breaths/min represents a 50% decrease from the client's baseline of 16 and falls well below the normal adult range of 12 to 20 breaths/min. Combined with difficulty arousing, this constellation of findings is a critical Recognize Cue that signals potential respiratory depression related to residual sedation or opioid effect — not typical recovery. Choice A incorrectly normalizes a dangerous finding. Choice C (fluid volume deficit) does not explain the altered respiratory rate or level of consciousness. Choice D (acute pain with guarding) would typically produce an elevated rather than a depressed respiratory rate.

Question 5

Client: 72-year-old male, Post-operative Day 1 following a total hip arthroplasty. History: Coronary artery disease, osteoarthritis, and controlled type 2 diabetes. 0800 Vital Signs (Baseline): BP 130/80 mmHg, HR 76 bpm, RR 14, Temp 98.6 F (37 C), SpO2 96% on room air. 1000 Situation: The client uses the call light and reports feeling very dizzy and cold all of a sudden. The nurse notes the client's skin is pale and slightly damp. 1005 Vital Signs: BP 102/60 mmHg, HR 104 bpm, RR 22, Temp 97.8 F (36.6 C), SpO2 93%.

Which clinical finding is the most significant indicator of a change in status when compared to the 0800 baseline?

The decrease in body temperature to 97.8 F (36.6 C).
The increase in respiratory rate to 22 breaths/min.
The decrease in blood pressure to 102/60 mmHg. (correct answer)
The decrease in SpO2 to 93%.

Explanation: The decrease in blood pressure from 130/80 to 102/60 mmHg represents the most significant single departure from this client's 0800 baseline and is the strongest indicator of hemodynamic instability in the immediate post-operative period. While the SpO2 drop to 93% (D) is a concerning finding that warrants continued monitoring, it is more likely a secondary consequence of the hemodynamic instability rather than its primary driver. The RR increase (B) and temperature decrease (A) are meaningful but individually represent less acute threats than the blood pressure change when considered against the full clinical picture of a post-operative patient.

Question 6

Which immediate nursing intervention should the nurse include in the client's plan of care?

Place the client in a supine position with the legs slightly elevated. (correct answer)
Encourage the client to ambulate in the hallway to increase blood pressure.
Administer the client's scheduled oral antihypertensive medication.
Assist the client into a left-lateral (Sims') position for comfort.

Explanation: Placing the client in a supine position with legs slightly elevated (modified shock position) promotes venous return to the central circulation and is an appropriate independent nursing action for a client with suspected hypovolemia. Ambulation (B) is contraindicated in a hemodynamically unstable client and risks a fall or further cardiovascular compromise. Administering an antihypertensive (C) is dangerous when the client is already hypotensive and could precipitate cardiovascular collapse. The Sims' position (D) provides no hemodynamic benefit for a client in suspected hypovolemic shock.

Question 7

The nurse has contacted the PHCP and reported the findings. While awaiting new orders, which action is appropriate for the nurse to perform?

Increase the rate of the current maintenance IV fluids according to facility protocol. (correct answer)
Offer the client a high-protein, high-calorie snack to increase energy.
Apply a cooling blanket to the client to address the damp skin.
Remove the client's sequential compression devices (SCDs) immediately.

Explanation: Increasing the IV fluid rate per facility protocol is an appropriate action within LPN/VN scope while awaiting new orders for a client with suspected hypovolemia. Many facilities authorize nurses to adjust maintenance IV flow rates within defined parameters in response to hemodynamic changes. Offering food (B) is inappropriate for a hemodynamically unstable client who may require urgent intervention or return to the OR. Applying a cooling blanket (C) misinterprets the diaphoresis, which is a sympathetic response to hemodynamic compromise rather than a sign of fever requiring cooling. Removing SCDs (D) is contraindicated and increases the client's already-elevated risk for DVT following arthroplasty.

Question 8

A nurse is measuring the temperature of an 88-year-old client in a rehabilitation center who is being treated for a fractured femur. The client's recorded baseline temperature is consistently 97.2 F (36.2 C). The client currently appears slightly confused and is complaining of a new burning sensation during urination. The nurse finds the current temperature is 99.4 F (37.4 C).

How should the nurse interpret this temperature reading for this specific client?

The reading is a normal temperature for a client of this advanced age.
The reading represents a potential low-grade fever based on the client's baseline. (correct answer)
The client is experiencing early signs of environmental hypothermia.
The previous baseline readings were likely recorded inaccurately.

Explanation: In older adults, baseline body temperatures are frequently lower than the traditional 98.6 F (37 C) reference value. This client's consistent baseline is 97.2 F; a current temperature of 99.4 F represents a 2.2 F increase from that personal baseline. When combined with new-onset confusion and dysuria — classic atypical presentations of urinary tract infection in the elderly — this elevation carries significant clinical importance even though 99.4 F would fall within normal range for a younger adult. Choice A incorrectly dismisses the finding by applying a population-level reference rather than a client-specific baseline. Choice C is incorrect; the temperature is elevated, not low. Choice D is an unsupported assumption that discards valid clinical documentation.

Question 9

The nurse on a medical-surgical unit is preparing to delegate the collection of afternoon vital signs for four stable clients to a UAP. The nurse wants to ensure the UAP understands when to report findings immediately.

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

Let me know if anyone's blood pressure seems to be a bit high this afternoon.
Check the vital signs for all four clients and record them in the electronic chart.
Notify me immediately if the heart rate for the client in room 402 is greater than 100 beats/min. (correct answer)
Please perform the vital sign checks as soon as you have finished with the linen changes.

Explanation: Effective delegation requires the nurse to provide specific, measurable, and actionable parameters. Stating a clear threshold (HR > 100 bpm for the client in room 402) ensures the UAP knows exactly when a finding constitutes a reportable deviation, removing ambiguity and promoting client safety. Choice A uses vague language ('a bit high') that does not give the UAP a clear threshold for reporting. Choice B instructs the UAP on documentation but omits any reporting parameters, meaning an abnormal finding might not be escalated to the nurse. Choice D addresses timing but provides no clinical guidance about what to report.

Question 10

A client with a 10-year history of chronic obstructive pulmonary disease (COPD) is being seen in a pulmonary clinic. The client's baseline SpO2 while resting is typically 88% to 91% on 2 L/min of oxygen via nasal cannula. During the current assessment, the nurse finds the SpO2 is 89%. The client is alert, speaking in full sentences, and denies any new shortness of breath.

What is the most appropriate nursing action in response to this finding?

Increase the client's oxygen flow rate to 4 L/min via nasal cannula.
Document the finding as consistent with the client's established baseline. (correct answer)
Call a rapid response alert for potential respiratory failure.
Assist the client into a supine position to rest their respiratory muscles.

Explanation: For clients with chronic conditions like COPD, the clinically relevant normal range is defined by the client's individual baseline, not population norms. An SpO2 of 89% falls within this client's established range of 88 to 91%, and the client is alert and asymptomatic — there is no indication for intervention. Increasing oxygen to 4 L/min (A) is potentially dangerous for clients with COPD who may rely on a hypoxic respiratory drive; elevating the SpO2 by increasing supplemental oxygen can blunt that drive, suppress ventilation, and lead to hypercapnic respiratory failure. Calling a rapid response (C) is not indicated for a stable finding within the client's known baseline. The supine position (D) would actually worsen oxygenation in a COPD client by limiting diaphragmatic excursion.

Question 11

A nurse is monitoring a client who has just started receiving their first dose of an intravenous (IV) antibiotic for a severe skin infection. The client's baseline vital signs taken 15 minutes ago were BP 120/80 mmHg, HR 80 bpm, and RR 16. Ten minutes into the infusion, the client calls out and says, 'I feel very itchy, and my chest feels tight.'

Which change in vital signs would most strongly support the nurse's hypothesis that the client is experiencing an allergic reaction?

The blood pressure decreases to 90/50 mmHg. (correct answer)
The heart rate decreases to 60 beats/min.
The respiratory rate remains at 16 breaths/min.
The body temperature increases to 101.2 F (38.4 C).

Explanation: Hypotension (BP 90/50 mmHg) is a hallmark sign of anaphylaxis and strongly supports the hypothesis of a severe allergic reaction when combined with the client's report of pruritus and chest tightness. In anaphylaxis, massive vasodilation leads to a sudden drop in systemic vascular resistance and blood pressure. Importantly, the expected cardiovascular response to anaphylaxis is tachycardia — a compensatory increase in heart rate — not bradycardia; a decrease in HR to 60 bpm (B) would actually argue against this hypothesis. A stable RR of 16 (C) would be inconsistent with the bronchospasm and respiratory distress typical of anaphylaxis. A temperature rise (D) is more suggestive of infection or a transfusion reaction rather than an acute allergic response, and would not be expected to develop within the first 10 minutes of an infusion.

Question 12

A nurse is caring for a client who received a dose of an IV opioid analgesic for severe post-operative pain 30 minutes ago. The client's baseline respiratory rate prior to the medication was 18 breaths/min. During the current check, the nurse finds the client is very groggy and has a respiratory rate of 10 breaths/min.

Which action should the nurse take first?

Attempt to arouse the client and assess their level of consciousness. (correct answer)
Immediately notify the PHCP of the change in respiratory rate.
Administer the prescribed PRN dose of an opioid reversal agent.
Document the respiratory rate and return to check the client in 30 minutes.

Explanation: The nurse must first perform focused data collection — specifically, attempting to arouse the client and assessing level of consciousness — before initiating further action. This follows the NCJMM Analyze Cues step: the degree of sedation must be established to accurately characterize the client's condition and determine the urgency of subsequent steps. Notifying the PHCP (B) is appropriate and will be necessary, but the nurse needs complete assessment data including the client's response to stimulation in order to give an accurate and actionable clinical report. Administering naloxone (C) is a dependent action requiring a prescription; it is premature without first confirming the depth of sedation, and when given indiscriminately it can precipitate acute opioid withdrawal and significant patient distress. Documenting and waiting 30 minutes (D) is dangerous and represents failure to respond to a significant deviation below the normal adult respiratory rate.

Question 13

During a routine health screening, a nurse is preparing to measure the blood pressure of an adult client. The nurse notes that the client has a large arm circumference, but the only blood pressure cuff available is a standard adult size, which is visibly too small for the client.

The nurse should recognize that using a blood pressure cuff that is too small for the client's arm will likely result in:

A falsely low blood pressure reading.
A falsely high blood pressure reading. (correct answer)
A perfectly accurate reading if the client remains still.
A reading that only affects the diastolic measurement.

Explanation: Using a blood pressure cuff that is too small for the client's arm circumference is a well-established technical error that produces a falsely elevated (high) blood pressure reading. When the cuff bladder is too narrow relative to the arm, greater external pressure is required to occlude the brachial artery, registering a number higher than the client's true pressure. This is clinically important because it can lead to misdiagnosis of hypertension. Conversely, a falsely low reading (A) results from using a cuff that is too large. Client stillness (C) does not compensate for improper cuff sizing. Both systolic and diastolic values are affected by an improperly sized cuff (D), not just diastolic.

Question 14

The nurse is reinforcing discharge teaching with a client who will be using a new home blood pressure monitor. The client is demonstrating how they will take their own measurements to ensure they are capturing an accurate baseline.

Which statement by the client indicates that further instruction is needed?

I will make sure to sit quietly in a chair for 5 minutes before I start.
I will keep my arm supported at the same level as my heart.
I will take my blood pressure as soon as I finish my morning cup of coffee. (correct answer)
I will keep a written log of all my readings to show the doctor at my next visit.

Explanation: Taking a blood pressure reading immediately after consuming caffeine requires further teaching. Caffeine is a stimulant that causes temporary vasoconstriction and a transient blood pressure elevation, which can produce an artificially high reading that does not reflect the client's true baseline. Clients should be instructed to avoid caffeine for at least 30 minutes before measuring. Choices A (resting quietly for 5 minutes), B (arm supported at heart level), and D (keeping a log) all reflect correct measurement technique — no further teaching is needed for those behaviors.

Question 15

The nurse at a community health clinic is reinforcing teaching with a 55-year-old client who was recently diagnosed with hypertension and started on a daily diuretic. The client is concerned about how to monitor their health at home and asks about the importance of tracking vital signs. The nurse is discussing the concept of a "baseline" versus a single "abnormal" reading.

Which statement should the nurse include when reinforcing information about blood pressure monitoring?

A blood pressure reading of 120/80 mmHg is the universal baseline for all adults regardless of age.
You should notify the clinic if your systolic blood pressure is consistently 20 mmHg above your usual range. (correct answer)
It is expected that your heart rate and blood pressure will decrease significantly for two hours after exercise.
You should only take your blood pressure when you are feeling symptomatic, such as having a headache.

Explanation: Education for the LPN/VN should focus on when to notify a provider based on deviations from the client's established baseline. The word 'consistently' is key — it distinguishes a clinically meaningful trend from a single isolated reading. Choice A is incorrect because baselines vary by individual; 120/80 mmHg is a general population reference, not a universal personal baseline. Choice C is incorrect; blood pressure and heart rate typically increase during exercise and return to baseline during recovery, not decrease below it. Choice D is incorrect and dangerous, as hypertension is often asymptomatic.

Question 16

The nurse at a pediatric clinic is collecting vital signs on a 6-month-old infant brought in for a wellness visit. The infant's baseline heart rate from previous visits is 130 bpm. While the infant is sleeping quietly in the caregiver's arms, the nurse finds the apical heart rate is 180 bpm.

How should the nurse recognize and handle this finding?

Recognize it as a normal heart rate for a sleeping infant of this age.
Assume it is a result of the infant reaching a new developmental milestone.
Interpret it as an expected physiological response to the sleeping state.
Identify it as a significant deviation from the baseline that requires follow-up. (correct answer)

Explanation: While infant heart rates are naturally higher than adult rates, 180 bpm in a sleeping infant represents a significant deviation from this specific infant's established baseline of 130 bpm. Sleep generally lowers heart rate, making an elevated HR while sleeping particularly notable and warranting investigation for potential causes such as fever, dehydration, or cardiac arrhythmia. Choice A incorrectly conflates age-appropriate population ranges with this infant's personal baseline. Choice C is incorrect; heart rate typically decreases during sleep in both infants and adults, so a sleeping state does not explain the elevation. Choice B has no clinical basis.

Question 17

The nurse recognizes that the sudden decrease in blood pressure accompanied by an increased heart rate most likely indicates which condition?

Acute postoperative pain following physical therapy.
Potential internal hemorrhage or significant fluid volume deficit. (correct answer)
Expected physiological recovery from the lingering effects of anesthesia.
An adverse effect of a newly administered dose of a diuretic.

Explanation: Hypotension combined with compensatory tachycardia, diaphoresis, pallor, and dizziness in a post-operative patient on Day 1 following joint arthroplasty constitutes the classic clinical picture of hypovolemia, most urgently suggesting potential internal hemorrhage or significant fluid volume loss. Acute pain (A) typically elevates both blood pressure and heart rate but does not produce the degree of hemodynamic instability seen here. Recovery from anesthesia (C) would not be expected to cause acute hemodynamic deterioration 8+ hours post-operatively. Diuretic administration (D) is not supported by the EHR data provided.

Question 18

A nurse is caring for a client who is two hours post-cardiac catheterization through the right femoral artery. The baseline pedal pulses were 2+ and equal bilaterally before the procedure. During the current assessment, the nurse finds the right pedal pulse is 1+ (weak) and the right foot feels cool to the touch compared to the left.

What is the priority nursing action?

Re-evaluate the pedal pulse and temperature of the foot in one hour.
Apply a warm, dry blanket specifically to the client's right foot.
Notify the PHCP immediately regarding the change in circulation. (correct answer)
Encourage the client to perform active range-of-motion exercises with the right leg.

Explanation: A decrease in pulse strength from 2+ to 1+ combined with a cool extremity on the side of a recent femoral arterial catheterization indicates potential arterial occlusion or compromised peripheral perfusion — a vascular emergency requiring immediate notification of the PHCP. Waiting one hour to re-evaluate (A) is dangerous; arterial occlusion can progress rapidly to irreversible ischemia and limb loss. Applying a warm blanket (B) treats a symptom while ignoring the underlying cause and could mask further deterioration. Active ROM exercises with the right leg (D) are contraindicated in the immediate post-catheterization period and could displace a thrombus or disrupt the arterial access site.

Question 19

Following an IV fluid bolus, the client's BP is 122/78 mmHg and HR is 82 bpm. The nurse knows the intervention was effective because:

The client reports that they no longer feel cold or damp.
The client's vital signs have returned toward their recorded baseline. (correct answer)
The respiratory rate has decreased from 22 to 16 breaths/min.
The client is now able to fall asleep comfortably.

Explanation: The gold standard for evaluating effectiveness of an intervention for hemodynamic instability is comparing the client's current vital signs to their established baseline. A BP of 122/78 mmHg and HR of 82 bpm represent a return toward the client's documented 0800 baseline (130/80 / 76 bpm), confirming effective volume resuscitation. Subjective symptom relief (A) is supportive but insufficient alone as an objective outcome measure. A return of RR to 16 (C) is within normal range and is a positive secondary finding, but it is not the primary indicator of hemodynamic effectiveness — note that an RR of 10 would have been abnormally low and would not indicate improvement. The ability to fall asleep (D) is a non-specific finding that does not constitute a reliable clinical outcome measure.

Question 20

Based on the current clinical data, the nurse determines the client is at the highest risk for which complication?

Hypovolemic shock. (correct answer)
Hospital-acquired pneumonia.
Deep vein thrombosis (DVT).
Surgical site infection.

Explanation: The current clinical presentation — acute hypotension, compensatory tachycardia, pallor, diaphoresis, and dizziness on post-operative Day 1 — represents the highest-priority hypothesis of hypovolemic shock, which is immediately life-threatening. While hospital-acquired pneumonia (B), DVT (C), and surgical site infection (D) are all legitimate post-operative risks for this client, none of them explain the acute hemodynamic changes present right now. Prioritizing hypotheses in clinical judgment requires the nurse to weight urgency and imminence; hypovolemic shock is the only hypothesis that accounts for the complete set of current findings and demands the most immediate action.
