🧠 Clinical Scenario Practice — Questions 31–60
31
A 58-year-old patient with severe COPD is admitted with an acute exacerbation. He is sitting upright, using accessory muscles, respiratory rate is 34/min, SpO₂ is 82% on room air, and he is unable to complete a full sentence. What should the nurse do FIRST?
- A. Place the patient flat and obtain a chest X-ray
- B. Position the patient upright, assess airway/breathing and initiate prescribed oxygen while monitoring response
- C. Encourage oral fluids and reassess after 30 minutes
- D. Ask the patient to walk to assess exercise tolerance
💡 Show Answer & Nursing Rationale
Ans. B
Sol. The immediate priority is impaired breathing and hypoxemia. Upright positioning improves ventilation, while prescribed oxygen and rapid ABC assessment address the immediate threat. The nurse should continuously reassess respiratory effort, SpO₂ and mental status.
🧠 Memory Trick: Severe dyspnea + low SpO₂ = ABC first.
32
A postoperative patient suddenly becomes restless and tachypneic. SpO₂ falls from 96% to 88%, and the patient says, “I can't breathe.” The patient is lying flat. What is the priority nursing action?
- A. Give oral analgesia and reassess in 30 minutes
- B. Raise the head of the bed, immediately assess airway and breathing, and provide prescribed oxygen/support
- C. Ask the patient to cough repeatedly while remaining flat
- D. Leave the patient to obtain the previous shift's notes
💡 Show Answer & Nursing Rationale
Ans. B
Sol. A sudden fall in oxygen saturation with respiratory distress requires immediate assessment and support. Positioning, ABC assessment and oxygen/support are more urgent than documentation or routine medication administration.
🧠 Memory Trick: Sudden desaturation = assess and support breathing immediately.
33
A patient vomits and then develops coughing and SpO₂ 84%. He is awake and has a strong, forceful cough. Which nursing action is most appropriate initially?
- A. Encourage effective coughing while assessing airway and oxygenation
- B. Immediately insert an oral airway despite the effective cough
- C. Give oral water to clear the airway
- D. Place the patient supine and wait for spontaneous improvement
💡 Show Answer & Nursing Rationale
Ans. A
Sol. A conscious patient with an effective cough may be able to clear aspirated material. The nurse should support the cough, assess airway patency and oxygenation, and escalate if the patient becomes unable to protect the airway or deteriorates.
🧠 Memory Trick: Effective cough = support the cough; ineffective cough = escalate airway management.
34
A conscious adult suddenly grabs his throat, cannot speak or cough effectively, and becomes cyanotic. What should the nurse prioritize?
- A. Give the patient water and encourage swallowing
- B. Activate the emergency response and initiate the recommended management for severe foreign-body airway obstruction
- C. Ask the patient to lie down and rest
- D. Wait until the patient becomes unconscious before intervening
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Inability to speak or cough effectively with cyanosis indicates severe airway obstruction. Immediate emergency action and appropriate foreign-body airway-obstruction treatment are required.
🧠 Memory Trick: Cannot speak/cough + cyanosis = severe airway obstruction.
35
A patient with a tracheostomy suddenly becomes severely distressed. SpO₂ is 78%, and the suction catheter cannot be advanced through the tracheostomy tube. What is the most appropriate priority?
- A. Continue forceful suctioning until the catheter passes
- B. Suspect obstruction or displacement, call for urgent help and immediately support airway/oxygenation according to protocol
- C. Give oral fluids
- D. Remove the tracheostomy tube without assistance
💡 Show Answer & Nursing Rationale
Ans. B
Sol. A catheter that cannot pass in a deteriorating tracheostomy patient raises concern for obstruction or displacement. Repeated forceful suctioning can worsen trauma. Immediate airway assessment and emergency support are required.
🧠 Memory Trick: Trach + sudden distress + catheter won't pass = think obstruction/displacement.
36
A patient with a recently created tracheostomy accidentally decannulates and develops respiratory distress. What should the nurse do FIRST?
- A. Leave the patient alone to obtain a replacement tube
- B. Activate emergency assistance and immediately support airway and oxygenation according to the tracheostomy emergency protocol
- C. Give the patient oral fluids
- D. Wait for the patient to become unconscious
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Accidental decannulation of a fresh tracheostomy can rapidly compromise the airway. The nurse should call for urgent assistance and provide airway/oxygenation support according to institutional protocol.
🧠 Memory Trick: Fresh trach + decannulation = emergency airway problem.
37
A patient with pneumonia is receiving antibiotics. He now has RR 30/min, BP 86/52 mmHg, new confusion, cool extremities and increasing weakness. Which nursing response has the highest priority?
- A. Document the findings and reassess at the end of the shift
- B. Recognize possible sepsis-related deterioration, initiate urgent escalation and support ABCs according to protocol
- C. Offer a large oral meal
- D. Encourage ambulation to improve circulation
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Hypotension, altered mental status, tachypnea and cool extremities suggest significant systemic deterioration and possible hypoperfusion. This requires immediate assessment, escalation and supportive care according to the sepsis/emergency protocol.
🧠 Memory Trick: Infection + hypotension + confusion = urgent deterioration.
38
A patient with acute pulmonary edema is extremely dyspneic, cannot tolerate lying flat, and has widespread crackles. Which nursing action should be prioritized?
- A. Place the patient upright and provide prescribed oxygen/respiratory support while urgently reassessing
- B. Place the patient flat to improve venous return
- C. Encourage the patient to drink a large amount of water
- D. Ask the patient to walk to reduce pulmonary congestion
💡 Show Answer & Nursing Rationale
Ans. A
Sol. Upright positioning can reduce the work of breathing and improve lung expansion. Oxygen and respiratory support are provided as prescribed while the patient is urgently reassessed and treated.
🧠 Memory Trick: Pulmonary edema + severe dyspnea = sit upright and support oxygenation.
39
A COPD patient is prescribed a Venturi mask for controlled oxygen delivery. The patient removes it because it feels uncomfortable and asks for a simple face mask. SpO₂ is now 95%. What should the nurse do?
- A. Change permanently to the simple mask because the SpO₂ is normal
- B. Reinforce the prescribed controlled-oxygen device, verify the correct FiO₂ and monitor the patient's clinical status
- C. Stop oxygen because SpO₂ is above 94%
- D. Allow the patient to choose any oxygen device
💡 Show Answer & Nursing Rationale
Ans. B
Sol. A Venturi mask provides a more controlled oxygen concentration. In a COPD patient, the nurse should not independently replace the prescribed device simply because a single SpO₂ reading appears acceptable. Verify the prescription/device settings and reassess.
🧠 Memory Trick: Controlled oxygen means controlled FiO₂—not simply 'more oxygen.'
40
A mechanically ventilated patient becomes agitated. The high-pressure alarm sounds repeatedly, SpO₂ begins to fall, and the patient is biting the endotracheal tube. What should the nurse do FIRST?
- A. Immediately silence the alarm and leave the patient
- B. Assess the patient and ventilator circuit for causes such as tube biting, secretions or bronchospasm while supporting oxygenation
- C. Increase tidal volume without assessment
- D. Disconnect the ventilator permanently
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Ventilator alarms should be treated as clinical warnings, not simply silenced. The nurse assesses the patient first and looks for reversible causes of increased airway pressure such as biting, secretions, kinking or bronchospasm.
🧠 Memory Trick: High pressure = think obstruction/resistance; assess patient first.
41
A ventilated patient develops a low-pressure alarm immediately after repositioning. On inspection, the ventilator tubing is visibly disconnected. What is the priority action?
- A. Reconnect the ventilator circuit and immediately reassess the patient and ventilation
- B. Increase PEEP before reconnecting the circuit
- C. Wait for respiratory therapy rounds
- D. Turn off all monitoring alarms
💡 Show Answer & Nursing Rationale
Ans. A
Sol. A visible circuit disconnection is a direct cause of a low-pressure alarm. Reconnecting the circuit restores the intended ventilatory pathway, followed by immediate reassessment of oxygenation and ventilation.
🧠 Memory Trick: Low pressure + visible disconnect = reconnect and reassess.
42
A mechanically ventilated patient develops a high-pressure alarm. On assessment, coarse breath sounds and visible airway secretions are present. What is the most appropriate nursing response?
- A. Assess the patient and perform suctioning if clinically indicated according to protocol
- B. Increase the ventilator pressure limit without assessment
- C. Ignore the alarm because the patient is sedated
- D. Immediately extubate the patient
💡 Show Answer & Nursing Rationale
Ans. A
Sol. Secretions can increase airway resistance and trigger a high-pressure alarm. The nurse should assess the patient and suction when clinically indicated, then reassess breath sounds, oxygenation and ventilator pressures.
🧠 Memory Trick: High pressure + secretions = assess and clear the airway if indicated.
43
During mechanical ventilation, the peak airway pressure suddenly increases while the plateau pressure remains unchanged. Which problem is most consistent with this pattern?
- A. Increased airway resistance such as secretions, bronchospasm or tube obstruction
- B. Sudden severe loss of lung compliance
- C. Complete ventilator power failure
- D. Low patient temperature
💡 Show Answer & Nursing Rationale
Ans. A
Sol. A rise in peak pressure with an unchanged plateau pressure generally points toward increased airway resistance rather than reduced lung compliance. Clinical assessment is still required to identify the exact cause.
🧠 Memory Trick: Peak ↑, plateau unchanged = resistance problem.
44
A patient with a chest tube suddenly develops increased dyspnea. The nurse finds that the tubing is sharply kinked beneath the patient's body. What should the nurse do first?
- A. Correct the kink and reassess respiratory status and chest-tube function
- B. Clamp the chest tube for one hour
- C. Remove the chest tube immediately
- D. Flush the chest tube forcefully
💡 Show Answer & Nursing Rationale
Ans. A
Sol. A kink can obstruct drainage and impair the chest-tube system. The immediate action is to restore unobstructed tubing and reassess the patient and drainage system.
🧠 Memory Trick: Chest tube + kink = restore patency; don't routinely clamp.
45
A patient with a chest tube suddenly drains 250 mL of bright-red blood in 30 minutes and becomes tachycardic. What is the priority nursing response?
- A. Ignore it because drainage is expected after chest surgery
- B. Immediately assess the patient, maintain support and urgently notify the responsible medical team according to protocol
- C. Clamp the tube routinely for 30 minutes
- D. Ask the patient to ambulate
💡 Show Answer & Nursing Rationale
Ans. B
Sol. A sudden large amount of fresh bloody drainage accompanied by tachycardia may indicate significant bleeding. The nurse should rapidly assess the patient, maintain support and escalate urgently according to institutional protocol.
🧠 Memory Trick: Sudden large bright-red drainage + instability = urgent escalation.
46
A patient with suspected pulmonary embolism develops sudden severe dyspnea, tachycardia and then hypotension. What should the nurse prioritize?
- A. Ask the patient to walk to improve circulation
- B. Immediately assess ABCs, activate emergency support and provide oxygen/other support according to protocol
- C. Offer oral fluids and wait
- D. Place the patient in a routine outpatient queue
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Hypotension with acute respiratory symptoms suggests potentially life-threatening cardiopulmonary compromise. Immediate ABC assessment and emergency response are the priority.
🧠 Memory Trick: PE + hypotension = treat as an emergency.
47
A patient with severe asthma receives bronchodilator therapy. Initially there was loud wheezing, but later the wheeze becomes very quiet while the patient becomes increasingly drowsy. What is the most concerning interpretation?
- A. The asthma is definitely improving because wheezing is less
- B. Airflow may be critically reduced with impending respiratory failure; urgent escalation is required
- C. The patient only needs oral fluids
- D. The nurse should stop all monitoring
💡 Show Answer & Nursing Rationale
Ans. B
Sol. A quieter chest in a deteriorating severe-asthma patient can indicate critically reduced airflow rather than improvement. Increasing drowsiness is an additional warning sign of respiratory failure.
🧠 Memory Trick: Severe asthma + quiet chest + drowsiness = danger, not improvement.
48
A COPD patient is drowsy. ABG shows pH 7.28, PaCO₂ 68 mmHg and HCO₃⁻ 31 mEq/L. How should the nurse interpret this result in the clinical context?
- A. Respiratory acidosis with hypercapnia and partial metabolic compensation, requiring urgent assessment/escalation
- B. Pure metabolic alkalosis
- C. Respiratory alkalosis
- D. Normal ABG
💡 Show Answer & Nursing Rationale
Ans. A
Sol. The low pH indicates acidemia and the elevated PaCO₂ indicates a respiratory cause. The elevated bicarbonate suggests renal compensation, but the low pH and drowsiness indicate clinically significant hypercapnia requiring urgent assessment.
🧠 Memory Trick: pH ↓ + PaCO₂ ↑ = respiratory acidosis.
49
A patient with acute respiratory distress has SpO₂ 88%, RR 32/min and increasing fatigue. Which finding would be the most concerning sign of impending respiratory failure?
- A. Patient asks for another pillow
- B. Increasing altered mental status with decreasing respiratory effort
- C. Mild anxiety while speaking full sentences
- D. Heart rate of 88/min with stable blood pressure
💡 Show Answer & Nursing Rationale
Ans. B
Sol. A change from compensatory tachypnea to fatigue, reduced respiratory effort and altered mental status suggests failing ventilation and oxygenation. This is an emergency warning sign.
🧠 Memory Trick: Tachypnea → fatigue → reduced effort = impending failure.
50
During tracheostomy suctioning, the patient's SpO₂ rapidly falls and heart rate drops. What should the nurse do immediately?
- A. Continue suctioning until the secretions are completely removed
- B. Stop suctioning, provide oxygen/ventilatory support as needed and reassess the patient
- C. Increase suction pressure
- D. Ask the patient to drink water
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Rapid desaturation and bradycardia during suctioning may result from hypoxemia or vagal stimulation. Suction should be stopped and the patient immediately supported and reassessed.
🧠 Memory Trick: Desaturation/bradycardia during suction = stop and support.
51
During oxygen therapy, an electrical spark occurs near oxygen equipment. What is the nurse's priority?
- A. Ignore it because oxygen itself is not flammable
- B. Remove/stop the ignition source if safe and activate the appropriate fire/oxygen emergency procedure
- C. Increase oxygen flow to improve ventilation
- D. Cover the oxygen outlet with a cloth
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Oxygen supports combustion. A spark near oxygen equipment creates a fire risk. The nurse should follow the facility's fire and oxygen emergency procedure and remove the ignition source if safe.
🧠 Memory Trick: Oxygen supports combustion—keep ignition sources away.
52
The nurse receives four patients. Which patient should be assessed FIRST?
- A. A stable COPD patient requesting a routine inhaler refill
- B. A pneumonia patient with mild cough and SpO₂ 95% on prescribed oxygen
- C. A severe asthma patient who is becoming drowsy, has minimal air entry and SpO₂ 82%
- D. A patient with chronic cough asking when discharge paperwork will be completed
💡 Show Answer & Nursing Rationale
Ans. C
Sol. The severe asthma patient has signs of critical airway/ventilation compromise: drowsiness, minimal air entry and severe hypoxemia. This patient has the most immediate threat to life.
🧠 Memory Trick: Priority = immediate threat to airway/breathing.
53
Four patients arrive in the emergency area. Which patient requires immediate nursing intervention?
- A. A patient with chronic bronchitis and stable baseline dyspnea
- B. A patient with pneumonia and temperature 38.1°C who is speaking comfortably
- C. A patient with acute stridor, cyanosis and inability to speak
- D. A patient requesting a routine nebulization refill
💡 Show Answer & Nursing Rationale
Ans. C
Sol. Stridor with cyanosis and inability to speak indicates severe upper-airway compromise. Airway emergencies take priority over stable respiratory complaints.
🧠 Memory Trick: Stridor + cyanosis + unable to speak = airway emergency.
54
A patient with suspected pulmonary tuberculosis presents to a crowded outpatient area. The patient is currently stable enough to wait briefly. What should the nurse prioritize?
- A. Keep the patient in the crowded waiting area without precautions
- B. Use source-control measures such as a surgical mask if tolerated and arrange prompt separation/isolation and appropriate assessment
- C. Give antibiotics without assessment
- D. Ask the patient to remove the mask while coughing
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Suspected infectious pulmonary TB requires prompt infection-control measures. Source control for the patient and separation from others help reduce transmission while the patient is assessed.
🧠 Memory Trick: Suspected TB = source control + separation + airborne precautions.
55
A patient with suspected infectious pulmonary TB needs to be transported to radiology. Which nursing action is most appropriate?
- A. Transport without precautions because the patient is leaving the ward
- B. Follow airborne-precaution transport procedures and have the patient wear a surgical mask if tolerated
- C. Place the patient in a crowded wheelchair queue
- D. Remove all respiratory protection during transport
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Patients with suspected infectious TB should be transported using appropriate airborne infection-control measures. The patient should wear source control when tolerated, while healthcare workers use the required respiratory protection.
🧠 Memory Trick: TB transport = minimize exposure + source control + staff protection.
56
A patient with severe dyspnea has a prescribed nebulized bronchodilator but cannot coordinate breathing through the mouthpiece. What is the most appropriate nursing action?
- A. Withhold the treatment permanently
- B. Use the prescribed/appropriate delivery method with assistance and monitor the patient's response
- C. Ask the patient to breathe into an empty cup
- D. Give the medication orally without an order
💡 Show Answer & Nursing Rationale
Ans. B
Sol. When a patient cannot coordinate with a mouthpiece, the nurse should use an appropriate prescribed delivery system according to the order and local protocol, while monitoring response and adverse effects.
🧠 Memory Trick: Right drug + right delivery method + reassessment.
57
A pneumonia patient on nasal oxygen repeatedly removes the cannula because of anxiety. SpO₂ is 84%. What should the nurse do first?
- A. Leave the cannula off until the patient calms down
- B. Assess the patient, restore prescribed oxygen, address the cause of anxiety and closely monitor response
- C. Tell the patient oxygen is optional
- D. Increase oxygen flow to maximum without assessment
💡 Show Answer & Nursing Rationale
Ans. B
Sol. The patient is significantly hypoxemic. The nurse should assess airway/breathing, restore the prescribed oxygen, address anxiety and reassess the response. Oxygen flow should not be changed arbitrarily outside the prescription/protocol.
🧠 Memory Trick: Hypoxemia first; then identify why the patient is removing oxygen.
58
A patient with a chest tube is transferred from ICU to the ward. Which information should the receiving nurse verify during handover and initial assessment?
- A. Only the patient's diet order
- B. Chest-tube indication, insertion site, drainage amount/character, water-seal/suction status, tubing patency and current respiratory status
- C. Only the patient's last temperature
- D. Only the time of discharge planning
💡 Show Answer & Nursing Rationale
Ans. B
Sol. A safe chest-tube handover must include why it is present, system setup, drainage trend, insertion site, tubing and the patient's current respiratory status. These details allow early recognition of complications.
🧠 Memory Trick: Chest tube handover = indication + system + drainage + patient status.
59
A patient with acute respiratory failure is being transferred to the ICU. Which information is most important for the nurse-to-nurse handover?
- A. Only the patient's name and age
- B. Airway/oxygen or ventilator requirement, respiratory trends, recent deterioration, interventions, response and current safety concerns
- C. Only the patient's meal preference
- D. Only the family contact number
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Respiratory handover should clearly communicate the airway status, oxygen/ventilator support, trends, recent events, interventions and response so the receiving team can continue care without loss of critical information.
🧠 Memory Trick: Good handover = what happened + what was done + current respiratory status.
60
Thirty minutes after extubation, a patient develops inspiratory stridor, RR 34/min and SpO₂ 88%. What should the nurse do?
- A. Wait 30 minutes because mild stridor is expected after extubation
- B. Immediately assess the airway and provide urgent respiratory support/escalation according to protocol
- C. Offer oral fluids
- D. Ask the patient to walk
💡 Show Answer & Nursing Rationale
Ans. B
Sol. Stridor with hypoxemia after extubation can indicate upper-airway obstruction and requires immediate assessment and escalation. The nurse should not wait for spontaneous improvement.
🧠 Memory Trick: Post-extubation stridor + desaturation = urgent airway assessment.
⚡ Quick Revision: Respiratory Priority Rules
- Airway before everything: stridor, inability to speak, severe obstruction and tracheostomy emergencies need immediate attention.
- Breathing: severe hypoxemia, increasing work of breathing, fatigue, altered mental status and falling respiratory effort are red flags.
- Ventilator: high pressure → think resistance/obstruction; low pressure → think leak/disconnection. Always assess the patient first.
- Chest tube: check the patient, tubing, drainage and system. Sudden large bloody drainage with instability requires urgent escalation.
- TB: suspected infectious pulmonary TB requires appropriate airborne infection-control measures and source control.
- Clinical priority: choose the patient with the most immediate threat to airway, breathing or circulation—not simply the most abnormal-looking number.
