1. A home health nurse visits a client who has COPD and receives oxygen at 2 L/min via nasal cannula. The client reports difficulty breathing. Which of the following actions is the nurse's priority?
- A. Increase the oxygen flow to 3 L/min.
- B. Assess the client's respiratory status.
- C. Call emergency services for the client.
- D. Have the client cough and expectorate secretions.
Correct answer: B
Rationale: When a client with COPD on oxygen therapy reports difficulty breathing, the priority action for the nurse is to assess the client's respiratory status. This involves evaluating the client's oxygen saturation levels, respiratory rate, effort of breathing, lung sounds, and overall respiratory distress. By assessing the client's respiratory status, the nurse can determine the severity of the situation and make appropriate decisions regarding further interventions, such as adjusting oxygen flow rate, providing respiratory treatments, or seeking emergency assistance if necessary.
2. A client in the intensive care unit is receiving teaching before removal of an endotracheal tube. Which of the following instructions should the nurse include in the teaching?
- A. Rest in a side-lying position after the tube is removed.
- B. Use the incentive spirometer every 4 hours after the tube is removed.
- C. Avoid speaking for extended periods.
- D. Vital signs will be monitored by a nurse every 15 minutes in the first hour after the tube is removed.
Correct answer: C
Rationale: It is essential to advise the client to avoid speaking for extended periods after the removal of the endotracheal tube to prevent strain on the vocal cords and allow the airway to recover. Speaking for prolonged periods can lead to irritation and potentially affect the healing process. The other options are also important post-extubation instructions, such as using the incentive spirometer to maintain lung function, positioning in a side-lying position for comfort, and frequent monitoring of vital signs to ensure the client's stability.
3. A client with asthma has developed viral pharyngitis. Which of the following findings should the nurse expect?
- A. Petechiae on the chest and abdomen
- B. WBC 16,000/mm3
- C. Negative throat culture
- D. Severe hyperemia of pharyngeal mucosa
Correct answer: C
Rationale: Viral pharyngitis is typically caused by a virus, not bacteria, so a negative throat culture is an expected finding. The presence of petechiae on the chest and abdomen (Choice A) is not a common manifestation of viral pharyngitis. Elevated WBC count (Choice B) is more indicative of a bacterial infection rather than a viral one. Severe hyperemia of the pharyngeal mucosa (Choice D) is a possible finding in pharyngitis but is not specific to viral pharyngitis.
4. A client develops a pulmonary embolism. Which of the following interventions should the nurse implement first?
- A. Give morphine IV.
- B. Administer oxygen therapy.
- C. Start an IV infusion of lactated Ringer's.
- D. Initiate cardiac monitoring.
Correct answer: B
Rationale: Administering oxygen therapy is the priority intervention for a client with a pulmonary embolism. Oxygen helps improve oxygenation levels and decrease the workload on the heart. It is crucial to ensure adequate oxygenation before other interventions are initiated. Morphine IV, starting an IV infusion of lactated Ringer's, and initiating cardiac monitoring are important interventions but come after ensuring adequate oxygenation.
5. When preparing a client for transfer to the ICU for placement of a pulmonary artery catheter, the nurse should explain that this catheter is used to monitor which of the following conditions?
- A. Intracranial pressure
- B. Spinal cord perfusion
- C. Renal function
- D. Hemodynamic status
Correct answer: D
Rationale: A pulmonary artery catheter is primarily used to monitor hemodynamic status. It provides essential information on cardiac output, preload, afterload, and overall cardiovascular function. This data helps healthcare providers manage the client's fluid status, cardiac function, and guide treatment interventions in critically ill patients. Monitoring intracranial pressure, spinal cord perfusion, or renal function would require different monitoring devices and techniques, not a pulmonary artery catheter.
