PCA Safety And Monitoring - NCLEX Rn

1. A 65-year-old client with chronic obstructive pulmonary disease is postoperative day 0 after lobectomy and is using an intravenous opioid PCA. Current assessment: pain 3/10, blood pressure 116/68 mm Hg, heart rate 74/min, respiratory rate 12/min, oxygen saturation 90% on 2 L/min nasal cannula; the client is awake but reports feeling "very sleepy." Which assessment finding requires IMMEDIATE intervention?
   Answer: Oxygen saturation of 90% on 2 L/min with new excessive sleepiness This question tests PCA safety and monitoring in a COPD client with new sedation symptoms. The priority concern related to PCA is hypoxia combined with excessive sleepiness suggesting opioid-induced depression. Oxygen saturation of 90% on 2 L/min with new excessive sleepiness requires immediate intervention because it indicates worsening respiratory status needing dose reduction or support. A pain score of 3/10 is adequate; heart rate of 74/min is normal; blood pressure of 116/68 mm Hg is stable. The decision-making principle for PCA monitoring is to interpret oxygen saturation in context with sedation and respiratory effort, especially in lung disease. Trends guide interventions. A transferable strategy for monitoring clients on PCA is to use continuous capnography in COPD clients to monitor CO2 levels alongside oxygenation.
2. A 60-year-old client with type 2 diabetes is 4 hours postoperative from lumbar fusion and is using an intravenous opioid PCA. Current assessment: pain 5/10, blood pressure 132/78 mm Hg, heart rate 80/min, respiratory rate 6/min, oxygen saturation 88% on room air; the client is difficult to awaken. What is the nurse's PRIORITY action with the PCA?
   Answer: Stop the PCA infusion and stimulate the client while calling for help per protocol An unarousable client with a respiratory rate of 6/min and oxygen saturation of 88% after opioid PCA use has severe opioid-induced respiratory depression. The nurse's priority is to stop the PCA infusion immediately, stimulate the client, and call for help per protocol so further opioid delivery is halted and emergency response/reversal can begin. Documenting the findings and planning to reassess sedation level in 15 minutes delays critical intervention while the client's breathing is already compromised. Administering an antiemetic for possible opioid-induced nausea treats a gastrointestinal side effect, not the respiratory depression and sedation that threaten airway and breathing. Delegating oxygen application and oxygen saturation rechecking to assistive personnel does not address hypoventilation, and it does not stop the opioid infusion or activate the response needed for possible overdose. The best answer is the action that stops the opioid, stimulates the client, and summons help per protocol.
3. A 54-year-old client is postoperative day 1 after total abdominal hysterectomy and is receiving hydromorphone via PCA. History includes hypertension. The client reports pain 9/10 and states, "I keep pressing the button but nothing is happening." Vital signs: temperature 37.0°C (98.6°F), blood pressure 146/88 mm Hg, heart rate 104/min, respiratory rate 18/min, oxygen saturation 96% on room air; the client is alert and oriented. What is the nurse's PRIORITY action with the PCA?
   Answer: Assess the IV site and verify the PCA tubing is connected and unclamped This question tests PCA safety and monitoring, focusing on troubleshooting PCA delivery problems when pain control is inadequate. The priority concern is identifying mechanical or technical issues that prevent effective PCA medication delivery before considering dose adjustments or alternative medications. The correct answer (A) addresses the highest priority by systematically checking the IV site patency and PCA tubing connections, which are the most common causes of PCA delivery failure. Option B (giving separate opioid) bypasses troubleshooting and could lead to overdose if the PCA begins working, option C (nonpharmacologic measures) delays addressing severe pain, and option D (delegating pain assessment) is inappropriate as PCA troubleshooting requires RN assessment. The decision-making principle is to first verify the PCA system is functioning properly before assuming the medication dose is inadequate. The transferable strategy is to systematically assess the entire PCA delivery system from IV site to pump settings when clients report ineffective pain relief despite multiple attempts.
4. A 44-year-old client with no chronic illnesses is postoperative day 1 after major abdominal surgery and is using an intravenous opioid PCA. Current assessment: pain 6/10, blood pressure 134/80 mm Hg, heart rate 86/min, respiratory rate 16/min, oxygen saturation 96% on room air; the client states the pain is worst with coughing and movement. What is the nurse's PRIORITY action with the PCA?
   Answer: Teach the client to use the PCA before activity and to splint the incision during coughing This question tests PCA safety and monitoring for optimizing use in activity-related pain. The priority concern related to PCA is educating on proactive dosing to manage pain spikes with movement or coughing. Teaching the client to use the PCA before activity and to splint the incision during coughing addresses the highest priority PCA issue by empowering effective self-management and preventing complications like atelectasis. Stopping PCA for oral opioids is premature; administering naloxone is for overdose, not pain; delegating coaching does not provide education. The decision-making principle for PCA monitoring involves integrating education on timing doses with activities to enhance mobility and recovery. Nonpharmacologic techniques complement PCA. A transferable strategy for monitoring clients on PCA is to encourage preemptive dosing and teach splinting techniques to all postoperative abdominal surgery clients for better pain control.
5. A 72-year-old client is 8 hours postoperative after hip fracture repair and is using an intravenous morphine PCA. History includes chronic kidney disease stage 3. Current assessment: pain 1/10, blood pressure 114/68 mm Hg, heart rate 58/min, respiratory rate 9/min, oxygen saturation 90% on 2 L/min nasal cannula; pupils are pinpoint and the client drifts off mid-sentence. Which assessment finding requires IMMEDIATE intervention?
   Answer: Pinpoint pupils with increasing somnolence This question tests PCA safety and monitoring, focusing on recognizing signs of opioid toxicity. The priority concern is identifying the constellation of symptoms that indicate dangerous levels of opioid accumulation requiring immediate intervention. The correct answer (A) identifies pinpoint pupils with increasing somnolence as the highest priority finding, as these are classic signs of opioid toxicity that, combined with the low respiratory rate, indicate impending respiratory arrest. Option B (HR 58/min) shows mild bradycardia, option C (pain 1/10) indicates good pain control, and option D (BP 114/68) represents acceptable blood pressure - while the bradycardia may be opioid-related, it is not immediately life-threatening. The decision-making principle is that neurological signs (pinpoint pupils, somnolence) combined with respiratory depression indicate opioid toxicity requiring immediate intervention including naloxone administration. The transferable strategy is to assess pupils and level of consciousness along with vital signs, as these neurological findings often precede complete respiratory arrest.
6. A 63-year-old client with hypertension is postoperative day 0 after hip replacement and is using an intravenous opioid PCA. Current assessment: pain 7/10, blood pressure 158/92 mm Hg, heart rate 102/min, respiratory rate 18/min, oxygen saturation 95% on room air; PCA history shows multiple attempts with few doses delivered. What is the nurse's PRIORITY action with the PCA?
   Answer: Assess the PCA pump settings and check whether the lockout interval is active This question tests PCA safety and monitoring when pain relief is inadequate despite attempts. The priority concern related to PCA is verifying proper device function and settings to ensure effective dosing. Assessing the PCA pump settings and checking whether the lockout interval is active addresses the highest priority PCA issue by identifying if timing prevents delivery. Administering a sedative is contraindicated for pain; documenting as expected ignores the issue; delegating comfort measures does not resolve technical problems. The decision-making principle for PCA monitoring involves reviewing pump history to differentiate between underdosing and tolerance. Adjustments should be provider-directed after assessment. A transferable strategy for monitoring clients on PCA is to correlate attempt-to-dose ratios with pain scores to optimize settings and improve outcomes.
7. A 54-year-old client with chronic kidney disease stage 3 is postoperative day 1 after total knee arthroplasty and is using an intravenous opioid PCA. Current assessment: pain 8/10, blood pressure 146/84 mm Hg, heart rate 104/min, respiratory rate 18/min, oxygen saturation 96% on room air; the client states, "I keep pressing the button and nothing is happening." What is the nurse's PRIORITY action with the PCA?
   Answer: Assess the IV site and verify the PCA tubing is connected and unclamped This question tests PCA safety and monitoring in a postoperative client reporting inadequate pain relief. The priority concern related to PCA is ensuring proper functioning of the delivery system to provide effective analgesia without overdose risk. Assessing the IV site and verifying the PCA tubing is connected and unclamped addresses the highest priority PCA issue because it identifies and resolves potential mechanical failures preventing medication delivery. Requesting an increase in PCA dose is inappropriate without confirming system functionality; teaching that some pain is expected does not address the reported malfunction; delegating vital signs does not resolve the immediate issue of non-delivery. The decision-making principle for PCA monitoring involves troubleshooting equipment first when clients report inefficacy, followed by reassessing pain and usage patterns. Regular checks of PCA pump history and infusion sites help ensure safe and effective pain management. A transferable strategy for monitoring clients on PCA is to educate them on proper button use and promptly investigate any reports of malfunction to maintain trust and efficacy in pain control.
8. A 41-year-old client with no significant medical history is postoperative day 0 after thyroidectomy and is using an intravenous opioid PCA. Current assessment: pain 6/10, blood pressure 130/82 mm Hg, heart rate 92/min, respiratory rate 18/min, oxygen saturation 96% on room air; the client states the pain is not improving and the nurse notes the PCA cartridge is empty. What is the nurse's PRIORITY action with the PCA?
   Answer: Initiate facility procedure to replace the PCA medication cartridge using appropriate double-checks This question tests PCA safety and monitoring when medication supply is depleted. The priority concern related to PCA is maintaining continuous pain control by promptly replacing empty cartridges. Initiating facility procedure to replace the PCA medication cartridge using appropriate double-checks addresses the highest priority PCA issue by ensuring safe resumption of therapy. Telling the client to press more frequently is ineffective with an empty cartridge; holding opioids risks uncontrolled pain; delegating pain scores delays resolution. The decision-making principle for PCA monitoring is to follow medication safety protocols, including independent double-checks for high-alert drugs like opioids. Inventory checks prevent interruptions. A transferable strategy for monitoring clients on PCA is to anticipate cartridge changes based on usage rates and prepare in advance to minimize pain flares.
9. A 68-year-old client is 6 hours postoperative after an open colectomy and is using an intravenous morphine patient-controlled analgesia (PCA). History includes chronic obstructive pulmonary disease (COPD). Current assessment: pain 2/10, respiratory rate 8/min, oxygen saturation 89% on 2 L/min nasal cannula, blood pressure 108/64 mm Hg, heart rate 62/min, and the client is difficult to arouse with slurred speech. Which assessment finding requires IMMEDIATE intervention?
   Answer: Respiratory rate of 8/min with difficult arousal This question tests PCA safety and monitoring, specifically recognizing signs of opioid-induced respiratory depression. The priority concern with PCA therapy is respiratory depression, which can lead to hypoxia, respiratory arrest, and death if not immediately addressed. The correct answer (B) identifies the combination of bradypnea (RR 8/min) and altered level of consciousness (difficult arousal) as the highest priority finding requiring immediate intervention to prevent respiratory failure. Option A (pain 2/10) indicates adequate pain control, option C (BP 108/64) shows acceptable blood pressure, and option D (HR 62/min) represents normal heart rate - none of these findings indicate life-threatening complications. The decision-making principle is that respiratory depression with altered consciousness represents a medical emergency requiring immediate intervention including stopping the PCA, stimulating the client, supporting ventilation, and preparing naloxone. The transferable strategy is to monitor respiratory rate, sedation level, and oxygen saturation together as a triad for early detection of opioid-induced respiratory depression.
10. A 72-year-old client with chronic obstructive pulmonary disease is postoperative day 0 after a colectomy and is receiving opioid medication via intravenous PCA. Current assessment: pain 2/10, blood pressure 124/76 mm Hg, heart rate 58/min, respiratory rate 10/min, oxygen saturation 92% on 2 L/min nasal cannula; the client is increasingly sleepy and answers questions slowly. Which finding indicates a complication of PCA therapy?
    Answer: Increasing sedation with a respiratory rate of 10/min This question tests PCA safety and monitoring for signs of opioid-related adverse effects in a client with COPD. The priority concern related to PCA is increasing sedation, which can precede respiratory depression in vulnerable clients. Increasing sedation with a respiratory rate of 10/min indicates a complication of PCA therapy because it signals central nervous system depression requiring prompt intervention. A pain score of 2/10 is effective analgesia and not a complication; a heart rate of 58/min may be normal or due to opioids but is not urgent; oxygen saturation of 92% on low-flow oxygen is often acceptable in COPD and not necessarily a complication. The decision-making principle for PCA monitoring is to prioritize sedation assessments over pain scores, as excessive sleepiness can lead to hypoventilation. Use tools like sedation scales to quantify changes and guide dose adjustments. A transferable strategy for monitoring clients on PCA is to integrate capnography or continuous pulse oximetry in high-risk clients to detect early respiratory changes.
11. A 58-year-old client with obstructive sleep apnea is postoperative day 0 after shoulder surgery and is using an intravenous opioid PCA. Current assessment: pain 2/10, blood pressure 120/72 mm Hg, heart rate 64/min, respiratory rate 11/min, oxygen saturation 94% on 2 L/min nasal cannula; the client's sedation score has increased from "awake" to "frequently drowsy, arousable." Which assessment finding requires IMMEDIATE intervention?
    Answer: Sedation increasing to frequently drowsy in a client with sleep apnea This question tests PCA safety and monitoring in clients with heightened respiratory risk. The priority concern related to PCA is progressive sedation in sleep apnea, which can exacerbate hypoventilation. Sedation increasing to frequently drowsy in a client with sleep apnea requires immediate intervention because it signals impending respiratory compromise needing dose adjustment or reversal. A pain score of 2/10 is adequate; a heart rate of 64/min is normal; oxygen saturation of 94% on oxygen is stable but not the issue. The decision-making principle for PCA monitoring is to act on sedation changes before respiratory decline, using scales for objectivity. High-risk clients warrant closer monitoring. A transferable strategy for monitoring clients on PCA is to trend sedation scores hourly initially and adjust based on risk factors like apnea.
12. A 69-year-old client with obstructive sleep apnea is postoperative day 0 after colectomy and is using an intravenous opioid PCA. Current assessment: pain 3/10, blood pressure 122/70 mm Hg, heart rate 72/min, respiratory rate 12/min, oxygen saturation 94% on 2 L/min nasal cannula; the provider writes an order to add a continuous basal infusion to the PCA. The nurse should QUESTION which aspect of PCA use?
    Answer: Adding a continuous basal infusion in a client with sleep apnea This question tests PCA safety and monitoring regarding regimen changes in high-risk clients. The priority concern related to PCA is avoiding continuous infusions that increase overdose risk in sleep apnea. Adding a continuous basal infusion in a client with sleep apnea should be questioned because it heightens the risk of nocturnal hypoventilation without pain feedback. Using oxygen saturation monitoring is standard; assessing sedation and respirations regularly is essential; encouraging incentive spirometry promotes lung health. The decision-making principle for PCA monitoring is to avoid basal rates in apnea unless closely monitored, preferring demand-only dosing. Risk-benefit analysis informs orders. A transferable strategy for monitoring clients on PCA is to collaborate with providers on settings, advocating for safer alternatives in vulnerable populations.
13. A 33-year-old client is 4 hours postoperative after appendectomy and is using a morphine PCA. History includes mild asthma. Current assessment: pain 6/10, blood pressure 124/76 mm Hg, heart rate 88/min, respiratory rate 12/min, oxygen saturation 98% on room air; the client's spouse is observed pressing the PCA button while the client sleeps. The nurse should QUESTION which aspect of PCA use?
    Answer: The spouse pressing the PCA button for the sleeping client This question tests PCA safety and monitoring, specifically the critical safety principle of PCA therapy. The priority concern is preventing proxy use of PCA, which bypasses the built-in safety mechanism of client-controlled administration. The correct answer (A) identifies the spouse pressing the PCA button for a sleeping client as the behavior requiring immediate intervention, as this dangerous practice can lead to overdose and respiratory depression. Option B (using PCA for postoperative pain) is appropriate use, option C (pain despite stable vitals) may require dose adjustment but is not unsafe, and option D (normal oxygen saturation) is expected. The decision-making principle is that only the client should press the PCA button, as consciousness serves as a natural safety mechanism preventing overdose. The transferable strategy is to educate all clients and family members that PCA means "patient-controlled" and explain why proxy use creates life-threatening risks.
14. A 28-year-old client with no chronic illnesses is 8 hours postoperative from exploratory laparotomy and is using an intravenous opioid PCA. Current assessment: pain 1/10, blood pressure 112/66 mm Hg, heart rate 60/min, respiratory rate 9/min, oxygen saturation 91% on room air; pupils are pinpoint and the client is difficult to keep awake. Which finding indicates a complication of PCA therapy?
    Answer: Pinpoint pupils with respiratory rate 9/min and decreased arousal This question tests PCA safety and monitoring for classic signs of opioid overdose. The priority concern related to PCA is pinpoint pupils and decreased arousal indicating central nervous system depression. Pinpoint pupils with respiratory rate 9/min and decreased arousal indicate a complication of PCA therapy because they are hallmark signs of opioid toxicity requiring intervention. A pain score of 1/10 is effective and not a complication; a heart rate of 60/min is normal for a young adult; blood pressure of 112/66 mm Hg is stable. The decision-making principle for PCA monitoring is to recognize triad symptoms of overdose—miosis, hypoventilation, and sedation—for prompt reversal. Holistic assessments include pupil checks in opioid use. A transferable strategy for monitoring clients on PCA is to include neurological checks like pupil response in routine vital sign rounds to catch early toxicity.
15. A 76-year-old client with mild cognitive impairment is postoperative day 0 after repair of a hip fracture and is using an intravenous opioid PCA. Current assessment: pain 5/10, blood pressure 136/78 mm Hg, heart rate 84/min, respiratory rate 14/min, oxygen saturation 95% on room air; the client is confused and repeatedly asks the nurse to "push the button for me." The nurse should QUESTION which aspect of PCA use?
    Answer: The client's ability to safely self-administer opioid doses using PCA This question tests PCA safety and monitoring in clients with cognitive challenges. The priority concern related to PCA is the client's ability to understand and safely use the device for self-dosing. The client's ability to safely self-administer opioid doses using PCA should be questioned because confusion impairs proper use and increases overdose risk. Reinforcing patient-only button pressing is standard; assessing pain with scales and behavior is appropriate; encouraging nonpharmacologic measures complements PCA. The decision-making principle for PCA monitoring is to evaluate cognitive status for PCA candidacy, considering alternatives like nurse-administered analgesia if impaired. Safety overrides convenience in vulnerable populations. A transferable strategy for monitoring clients on PCA is to assess orientation and comprehension before initiating and re-evaluate with changes in mental status.
16. A 51-year-old client with obstructive sleep apnea (uses CPAP at home) is admitted to a surgical unit after bariatric surgery and is using an intravenous opioid PCA. Current assessment: pain 4/10, blood pressure 126/74 mm Hg, heart rate 70/min, respiratory rate 12/min, oxygen saturation 93% on 2 L/min nasal cannula; the client is somnolent but arousable. What is the nurse's PRIORITY action with the PCA?
    Answer: Ensure continuous oxygen saturation monitoring and frequent sedation/respiratory assessments This question tests PCA safety and monitoring in a high-risk client with obstructive sleep apnea. The priority concern related to PCA is the increased risk of respiratory depression due to somnolence and apnea. Ensuring continuous oxygen saturation monitoring and frequent sedation/respiratory assessments addresses the highest priority PCA issue by enabling early detection of hypoxia or oversedation. Encouraging button presses is standard but not priority over monitoring; requesting a basal infusion increases risk in apnea; delegating ambulation does not address monitoring needs. The decision-making principle for PCA monitoring is to heighten surveillance in clients with sleep disorders using tools like continuous oximetry. Risk stratification guides frequency of assessments. A transferable strategy for monitoring clients on PCA is to incorporate home CPAP use postoperatively and monitor for apnea episodes during sleep.
17. A 45-year-old client is 10 hours postoperative after bowel resection and is using a hydromorphone PCA. History includes gastroesophageal reflux disease. Assessment: pain 2/10, blood pressure 110/66 mm Hg, heart rate 70/min, respiratory rate 8/min, oxygen saturation 93% on room air; the client is difficult to arouse and has shallow respirations. What is the nurse's PRIORITY action with the PCA?
    Answer: Stop the PCA infusion, attempt to arouse the client, support ventilation as needed, and prepare to administer naloxone per protocol This question tests PCA safety and monitoring, specifically the emergency response to opioid-induced respiratory depression. The priority concern is recognizing and responding to life-threatening respiratory depression that requires immediate reversal. The correct answer (A) addresses the highest priority with the correct sequence of interventions: stop the PCA, attempt arousal, support breathing, and prepare naloxone for this client showing severe respiratory depression (RR 8/min with difficult arousal). Option B (reassessing in 30 minutes) dangerously delays intervention, option C (requesting antiemetic) addresses a non-existent problem, and option D (delegating oxygen adjustment) is inappropriate when immediate RN intervention is required. The decision-making principle is that respiratory rate below 10/min with altered consciousness constitutes a medical emergency requiring immediate PCA cessation and naloxone administration. The transferable strategy is to memorize the emergency response sequence for opioid overdose: stop the drug, stimulate the client, support ventilation, and administer reversal agent.
18. A 67-year-old client with obesity and obstructive sleep apnea is 6 hours postoperative from an open cholecystectomy and is using an intravenous patient-controlled analgesia (PCA) pump with opioid medication. Current assessment: pain 3/10, blood pressure 118/70 mm Hg, heart rate 62/min, respiratory rate 8/min, oxygen saturation 90% on 2 L/min nasal cannula, difficult to arouse and drifts off during conversation. Which assessment finding requires IMMEDIATE intervention?
    Answer: Respiratory rate of 8/min with difficulty arousing the client This question tests PCA safety and monitoring in a postoperative client with risk factors for respiratory compromise. The priority concern related to PCA is opioid-induced respiratory depression, particularly in clients with obesity and obstructive sleep apnea. The respiratory rate of 8/min with difficulty arousing the client addresses the highest priority PCA issue because it indicates potential oversedation and hypoventilation requiring immediate intervention to prevent respiratory arrest. A pain rating of 3/10 is acceptable pain control and does not require immediate action; a heart rate of 62/min is within normal limits and not concerning; a blood pressure of 118/70 mm Hg is stable and does not indicate a problem. The decision-making principle for PCA monitoring involves prioritizing airway and breathing assessments using the ABC framework, as opioids can depress the central nervous system. Frequent monitoring of respiratory rate, depth, oxygen saturation, and sedation level is essential to detect early signs of complications. A transferable strategy for monitoring clients on PCA is to use a standardized sedation scale, such as the Pasero Opioid-Induced Sedation Scale, to guide interventions and prevent adverse events.
19. A 36-year-old client with no significant medical history is postoperative day 0 after orthopedic surgery and is using an intravenous opioid PCA. Current assessment: pain 9/10, blood pressure 150/88 mm Hg, heart rate 110/min, respiratory rate 20/min, oxygen saturation 97% on room air; the PCA pump display shows "lockout" and the client has pressed the button repeatedly. What is the nurse's PRIORITY action with the PCA?
    Answer: Assess the timing of the last dose and explain the lockout interval while evaluating need for additional analgesia The priority is to assess when the client last received a dose and explain the lockout interval, while also evaluating the need for additional analgesia. This addresses the client's severe pain while respecting the safety features of the PCA. Turning off the lockout feature would override the pump's programmed limits and could lead to an overdose, so it is unsafe. Telling the client to stop pressing the button is based on the incorrect assumption that repeated presses will cause an overdose after the lockout; it also does not address the client's pain. Delegating distraction to assistive personnel is a comfort measure, not the priority, because it does not include assessing the timing of the last dose or considering breakthrough analgesia. The nurse should first assess the situation, educate the client about the lockout, and then plan appropriate pain management.
20. A 59-year-old client with depression is postoperative day 1 after abdominal hysterectomy and is using an intravenous opioid PCA. Current assessment: pain 5/10, blood pressure 124/78 mm Hg, heart rate 82/min, respiratory rate 14/min, oxygen saturation 96% on room air; the client asks if the nurse can "push the PCA button every 10 minutes" to keep pain at zero. The nurse should QUESTION which request related to PCA use?
    Answer: The nurse pressing the PCA button on a schedule for the client This question tests PCA safety and monitoring regarding proper administration roles. The priority concern related to PCA is maintaining the patient-controlled aspect to prevent overdose. The nurse pressing the PCA button on a schedule for the client should be questioned because it bypasses safety features and risks oversedation. The client using the button when pain increases is correct; using repositioning and splinting with PCA is appropriate; assessing pain and sedation regularly is essential. The decision-making principle for PCA monitoring is to adhere to patient-only activation to ensure doses align with perceived pain. Ethical guidelines prohibit proxy dosing. A transferable strategy for monitoring clients on PCA is to educate staff and clients on PCA principles to reinforce safe, autonomous use.
