Critical Care Nursing Questions and Answers PDF Questions

Question 1 of 5

When caring for a patient with a pulmonary artery (PA) pressure catheter, the nurse observes that the PA waveform indicates that the catheter is in the wedged position. Which action should the nurse take next?

Correct Answer: C

Rationale: The correct answer is C: Notify the health care provider. When the PA waveform indicates the catheter is in the wedged position, it means the catheter tip is in the pulmonary artery, potentially causing complications. The nurse should notify the healthcare provider immediately to assess and reposition the catheter to prevent further issues. Zero balancing the transducer (A) or activating the fast flush system (B) are not appropriate actions for this situation. Deflating and reinflating the PA balloon (D) could exacerbate the issue and should only be done under the guidance of the healthcare provider.

Question 2 of 5

The critical care unit environment is very stressful for patients, families, and staff. What nursing action is directed at reducing environmental stress?

Correct Answer: D

Rationale: The correct answer is D: Maintaining quiet during hours of sleep. This action is essential in reducing environmental stress in the critical care unit as it promotes a restful environment for patients and allows for better sleep quality. Noise can disrupt sleep patterns and increase stress levels. Constant evaluation of patient status (A) is important but does not directly address environmental stress. Limiting visits to immediate family (B) can be beneficial in some cases but may not always reduce environmental stress. Bathing all patients during hours of sleep (C) may actually increase stress as it can be disruptive and uncomfortable for patients. Overall, maintaining a quiet environment during sleep hours is the most effective nursing action to reduce environmental stress in the critical care unit.

Question 3 of 5

The nurse caring for a mechanically ventilated patient prepares to include which strategies to prevent ventilator-associated pneumonia should be into the patient�s plan of care? (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A: Drain condensate from the ventilator tubing away from the patient. This is crucial to prevent ventilator-associated pneumonia as stagnant condensate can harbor harmful bacteria. By draining it away from the patient, the risk of bacterial growth and subsequent aspiration is minimized. Elevating the head of the bed (choice B) helps prevent aspiration but is not specific to preventing ventilator-associated pneumonia. Instilling normal saline during suctioning (choice C) can increase the risk of infection. Performing regular oral care with chlorhexidine (choice D) is important for oral hygiene but not directly related to preventing ventilator-associated pneumonia.

Question 4 of 5

A patient in a critical care unit has increased stress from the constant noise and light levels. What nursing intervention best attenuates these sources of stress?

Correct Answer: B

Rationale: The correct answer is B: Dimming lights during the night. This intervention helps reduce stress by creating a more calming environment, promoting rest and sleep. Constant observation (choice A) may increase stress due to lack of privacy. Frequent group rounds (choice C) may disrupt rest. Use of tile floors (choice D) is unrelated to addressing noise and light stress.

Question 5 of 5

What factors associated with the critical care unit can pred ispose the client to increased pain and anxiety? (Select all that apply.)

Correct Answer: A

Rationale: The presence of an endotracheal tube can predispose the client to increased pain and anxiety due to discomfort, difficulty breathing, and potential for aspiration. The tube insertion process itself can be painful and traumatic. Frequent vital sign assessment, monitor alarms, and room temperature are not directly associated with increased pain and anxiety from the endotracheal tube.
