Critical Care Nursing Cardiac Questions Questions

Question 1 of 5

When assisting with the placement of a pulmonary artery (PA) catheter, the nurse notes that the catheter is correctly placed when the monitor shows a:

Correct Answer: D

Rationale: Step-by-step rationale for Answer D being correct: 1. PA catheter measures PA pressures. 2. PAWP reflects left atrial pressure. 3. Correct placement shows typical PAWP tracing. 4. PA pressure waveform (A) is not specific to PAWP. 5. Systemic arterial pressure tracing (B) is unrelated. 6. Systemic vascular resistance tracing (C) is not monitored by PA catheter.

Question 2 of 5

The nurse is caring for a patient with an admitting diagnosis of congestive failure. While attempting to obtain a pulmonary artery occlusion pressure in the supine position, the patient becomes anxious and tachypneic. What is the best action by the nurse?

Correct Answer: D

Rationale: The correct answer is D: Elevate the head of the bed 45 degrees while recording pressures. Rationale: 1. Elevating the head of the bed will help improve the patient's breathing by reducing the pressure on the diaphragm. 2. This position will also help alleviate the patient's anxiety and tachypnea, promoting better oxygenation. 3. Recording pressures in this position will provide accurate data for monitoring the patient's condition. Summary: A: Limiting the supine position to 10 seconds does not address the underlying issues causing the patient's anxiety and tachypnea. B: Administering anxiety medications without addressing the positioning issue may not effectively manage the patient's symptoms. C: Encouraging the patient to take slow deep breaths is helpful, but changing the position of the patient is more crucial in this situation.

Question 3 of 5

Which interventions may be included during �terminal we aning�? (Select all that apply.)

Correct Answer: B

Rationale: The correct answer is B because during terminal weaning, the artificial ventilation is discontinued while maintaining the artificial airway to ensure comfort and support. This allows the patient to breathe on their own with support as needed. Explanation: 1. Option A: Complete extubation following ventilator withdrawal may not be suitable during terminal weaning as it involves removing the breathing tube entirely. 2. Option C: Discontinuation of anxiolytic and pain medications may not always be appropriate during terminal weaning as it depends on the patient's comfort needs. 3. Option D: Titration of ventilator support based on blood gas determinations is not typically done during terminal weaning as the focus is on gradual withdrawal of ventilation support while maintaining comfort.

Question 4 of 5

In the critically ill patient, an incomplete assessment and/or management of pain or anxiety may be hampered by which of the following? (Select all that apply.)

Correct Answer: A

Rationale: Step-by-step rationale: 1. Administration of neuromuscular blocking agents can hinder pain or anxiety assessment as it paralyzes the patient, preventing them from communicating discomfort. 2. Delirium may affect the patient's ability to express pain or anxiety, but it does not directly impede assessment and management. 3. Effective nurse communication and assessment skills facilitate, rather than hamper, pain or anxiety assessment. 4. Nonverbal patients can still communicate pain or anxiety through nonverbal cues, so they do not necessarily hinder assessment.

Question 5 of 5

The nurse educator is evaluating the performance of a new registered nurse (RN) who is providing care to a patient who is receiving mechanical ventilation with 15 cm H2O of peak end-expiratory pressure (PEEP). Which action indicates that the new RN is safe?

Correct Answer: B

Rationale: The correct answer is B: The RN uses a closed-suction technique to suction the patient. This is the safe action because closed-suction technique minimizes the risk of ventilator-associated infections by maintaining a closed system during suctioning, reducing the exposure to pathogens. Closed-suction systems also help maintain lung compliance and oxygenation levels during the suctioning process. Rationale: Option A is incorrect because suctioning every 1 to 2 hours may be too frequent and can lead to hypoxia and mucosal damage. Option C is incorrect as taping the connection between the ventilator tubing and ET can interfere with the proper functioning of the ventilator and increase the risk of disconnection. Option D is incorrect because changing ventilator circuit tubing routinely every 48 hours is not evidence-based practice and can increase the risk of contamination and unnecessary costs.
