1. 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.
2. A client with COPD is developing a plan of care. Which of the following interventions should the nurse include in the plan?
- A. Restrict the client's fluid intake to less than 2 L/day
- B. Provide the client with a low-protein diet
- C. Have the client use the early-morning hours for exercise and activity
- D. Instruct the client to use pursed-lip breathing
Correct answer: D
Rationale: In COPD, pursed-lip breathing helps improve breathing efficiency by maintaining positive pressure in the airways, preventing airway collapse, and promoting oxygenation. This technique assists in controlling respiratory rate, reducing dyspnea, and enhancing oxygen saturation levels. Restricting fluid intake is not typically a part of COPD management. Providing a low-protein diet is not a standard intervention for COPD. Early-morning hours are generally not recommended for exercise due to cooler temperatures and higher pollution levels, which can exacerbate COPD symptoms.
3. A healthcare professional is auscultating the lungs of a client who has pleurisy. Which of the following adventitious breath sounds should the professional expect to hear?
- A. Loud, scratchy sounds
- B. Squeaky, musical sounds
- C. Popping sounds
- D. Snoring sounds
Correct answer: A
Rationale: When auscultating the lungs of a client with pleurisy, the healthcare professional should expect to hear loud, scratchy sounds. These sounds are characteristic of pleurisy, which is an inflammation of the pleura, causing a rough, grating sound during breathing.
4. A client is planning to perform nasotracheal suction for a client who has COPD and an artificial airway. Which of the following actions should the nurse take?
- A. Perform suctioning for up to four passes.
- B. Apply suction to the catheter when advancing it into the trachea.
- C. Preoxygenate the client with 100% oxygen for up to 3 min.
- D. Limit each suction pass to 25 seconds.
Correct answer: C
Rationale:
5. A client who is receiving mechanical ventilation and has an ideal weight of 60 kg should have the tidal volume set at which of the following?
- A. 300 mL
- B. 480 mL
- C. 800 mL
- D. 950 mL
Correct answer: B
Rationale: Tidal volume is the amount of air delivered with each breath during mechanical ventilation. A common formula used to calculate tidal volume is 6-8 mL/kg of ideal body weight. For a client with an ideal weight of 60 kg, the expected tidal volume would be 60 kg x 6-8 mL/kg = 360-480 mL. Therefore, the most appropriate choice is 480 mL (Option B), which falls within the expected range based on the client's weight.
