1. A nurse is assessing an adult client who has been admitted with an acute illness.
Which assessment finding requires the most immediate follow-up?
A. Oral temperature of 37.4°C (99.3°F)
B. New-onset confusion and restlessness
C. Heart rate of 88 beats/min
D. Respiratory rate of 18 breaths/min
Rationale: New-onset confusion and restlessness can indicate inadequate oxygenation, impaired
perfusion, infection, or another acute physiologic change. The nurse should investigate this
finding promptly because neurologic changes may be an early sign of deterioration.
2. A client reports shortness of breath while lying flat but states that breathing
improves when sitting upright. Which term best describes this finding?
A. Bradypnea
B. Apnea
C. Orthopnea
D. Tachypnea
Rationale: Orthopnea is difficulty breathing when lying flat that improves when the client
assumes an upright position. It is commonly associated with conditions that impair cardiac or
pulmonary function.
3. Before administering oxygen to an adult client with respiratory distress, which
assessment is most important?
A. Bowel sounds
B. Skin turgor
C. Peripheral pulses
,D. Oxygen saturation and respiratory effort
Rationale: Oxygen saturation and respiratory effort provide immediate information about the
severity of impaired oxygenation and respiratory compromise. These findings help determine the
urgency of intervention.
4. A client with pneumonia has an oxygen saturation of 88% on room air and is
visibly using accessory muscles to breathe. What is the nurse's priority action?
A. Initiate prescribed oxygen therapy and reassess respiratory status
B. Encourage the client to drink several glasses of water
C. Place the client in a supine position
D. Obtain a detailed dietary history
Rationale: The client has evidence of impaired oxygenation and increased work of breathing.
Supporting oxygenation and reassessing the respiratory response are immediate priorities.
5. Which assessment finding is most consistent with hypoxemia?
A. Warm, flushed skin
B. Increased appetite
C. Restlessness and altered mental status
D. Increased urinary output
Rationale: The brain is highly sensitive to inadequate oxygenation. Restlessness, anxiety,
confusion, and changes in level of consciousness can occur with hypoxemia.
6. A nurse is teaching a client how to use an incentive spirometer after abdominal
surgery. Which instruction is appropriate?
A. Exhale forcefully into the device
B. Inhale slowly and deeply through the mouthpiece
C. Use the device only when shortness of breath occurs
D. Take rapid shallow breaths through the mouthpiece
,Rationale: Incentive spirometry promotes sustained maximal inspiration, helping expand the
lungs and reduce postoperative atelectasis. The client should inhale slowly and deeply rather
than rapidly.
7. A postoperative client suddenly develops sharp chest pain, severe dyspnea,
tachycardia, and anxiety. Which complication should the nurse suspect?
A. Atelectasis
B. Pleural effusion
C. Pneumonia
D. Pulmonary embolism
Rationale: Sudden dyspnea, pleuritic chest pain, tachycardia, and anxiety are classic warning
signs of pulmonary embolism. This is a potentially life-threatening emergency requiring
immediate intervention.
8. A client with chronic obstructive pulmonary disease is receiving oxygen therapy.
Which nursing action is most appropriate?
A. Administer the highest possible oxygen concentration
B. Discontinue oxygen whenever the client becomes sleepy
C. Administer oxygen as prescribed and monitor respiratory status and oxygenation
D. Encourage the client to breathe rapidly to increase oxygen intake
Rationale: Oxygen should be administered according to the prescribed target and carefully
monitored. Clients with COPD require individualized oxygen management rather than
indiscriminate administration of high concentrations.
9. Which position generally promotes lung expansion in a client experiencing
respiratory distress?
A. High-Fowler's position
B. Flat supine position
C. Trendelenburg position
D. Prone position with the head flat
, Rationale: High-Fowler's positioning allows greater chest expansion, improves diaphragmatic
movement, and can reduce the work of breathing in many clients with respiratory distress.
10. A nurse is caring for a client with asthma who develops increasing wheezing and
difficulty speaking in complete sentences. What does this finding indicate?
A. The asthma attack is resolving
B. The client is experiencing normal exertional breathing
C. The client has adequate ventilation
D. The respiratory condition is worsening and requires prompt intervention
Rationale: Difficulty speaking in complete sentences reflects significant respiratory compromise.
Increasing work of breathing and worsening symptoms require prompt assessment and
treatment.
11. A client with heart failure reports gaining 2.5 kg (5.5 lb) over several days. Which
explanation is most likely?
A. Increased muscle mass
B. Fluid retention
C. Improved nutritional status
D. Decreased cardiac workload
Rationale: Rapid weight gain over a short period is more consistent with fluid accumulation than
tissue gain. Daily weights are useful for detecting changes in fluid balance in clients with heart
failure.
12. Which finding is most characteristic of left-sided heart failure?
A. Dependent peripheral edema only
B. Enlarged liver
C. Pulmonary crackles and dyspnea
D. Jugular venous distention without respiratory symptoms
Rationale: Left-sided heart failure causes blood to back up into the pulmonary circulation,
producing pulmonary congestion, crackles, dyspnea, and potentially pulmonary edema.
