Critical Care Nursing Practice Questions Questions

Question 1 of 5

What diagnostic procedure is required to make a definitive diagnosis of pulmonary embolism?

Correct Answer: C

Rationale: The correct answer is C: High resolution multidetector CT angiogram. This diagnostic procedure is required for a definitive diagnosis of pulmonary embolism because it provides detailed imaging of the pulmonary vasculature, allowing visualization of blood clots in the pulmonary arteries. A: Arterial blood gas (ABG) analysis does not directly diagnose pulmonary embolism but may show signs of hypoxemia or respiratory alkalosis, which can be seen in some cases of pulmonary embolism. B: Chest x-ray examination may show nonspecific findings such as atelectasis or pleural effusion but cannot definitively diagnose pulmonary embolism. D: Ventilation-perfusion scanning is another imaging modality used in the diagnosis of pulmonary embolism, but it is less commonly used compared to CT angiogram due to lower sensitivity and specificity.

Question 2 of 5

The nurse plans a teaching session with a client but postpones the planned session based on which nursing problem?

Correct Answer: C

Rationale: Step-by-step rationale for choice C: 1. Activity intolerance is a priority nursing problem postoperatively due to pain. 2. Postoperative pain can limit the client's ability to perform activities. 3. Addressing activity intolerance is crucial for promoting recovery and preventing complications. 4. Delaying the teaching session helps the nurse focus on managing pain first. Summary of why other choices are incorrect: - Choice A: Knowledge deficit can be addressed after managing immediate postoperative issues. - Choice B: Treatment regimen management is important but may not be as urgent as addressing activity intolerance related to pain. - Choice D: Noncompliance with exercise plan can be addressed once the client's pain and activity intolerance are under control.

Question 3 of 5

A young adult patient with metastatic cancer, who is very close to death, appears restless. The patient keeps repeating, 'I am not ready to die.' Which action is best for the nurse to take?

Correct Answer: B

Rationale: The correct answer is B because sitting at the bedside and asking if there is anything the patient needs demonstrates empathy and support. It allows the patient to express their concerns and fears, providing emotional comfort. It shows the nurse is actively listening and willing to help address any immediate needs or concerns. Choice A is incorrect because it dismisses the patient's feelings and may come across as invalidating. Choice C is incorrect because insisting that family members remain may not be what the patient needs at that moment and could cause additional stress. Choice D is incorrect because it does not address the patient's emotional distress and may not be true in the context of terminal illness.

Question 4 of 5

The family is considering withdrawing life-sustaining measures from the patient. The nurse knows that ethical principles for withholding or withdrawi ng life-sustaining treatments include which of the following?

Correct Answer: A

Rationale: The correct answer is A because it aligns with the ethical principle of patient autonomy, which emphasizes the patient's right to make decisions about their own care. Withholding or withdrawing life-sustaining treatments, including nutrition, antibiotics, and blood products, respects the patient's autonomy. This choice also reflects the principle of beneficence, as it aims to prevent unnecessary suffering and respects the patient's wishes. Option B is incorrect because it focuses on pain and anxiety management rather than the broader ethical considerations of withholding life-sustaining treatments. Option C is incorrect because withdrawing life-sustaining treatments while a patient is receiving paralytic agents can pose additional risks and complications, potentially conflicting with the principles of nonmaleficence and beneficence. Option D is incorrect because the primary goal of withdrawing or withholding treatments is not to hasten death but to respect the patient's autonomy and quality of life. This choice does not align with the ethical principles of patient-centered care.

Question 5 of 5

Daily weights are being recorded for the patient with a urine output that has been less than the intravenous and oral intake. The weight yesterday was 97.5 kg. This morning it is 99 kg. The nurse understands that this corresponds to a(n)

Correct Answer: A

Rationale: The correct answer is A: fluid retention of 1.5 liters. The weight gain from 97.5 kg to 99 kg indicates an increase in fluid retention. This difference of 1.5 kg corresponds to fluid retention of 1.5 liters, as 1 liter of water weighs approximately 1 kg. This weight gain suggests that the patient is retaining more fluid than they are excreting, leading to an increase in weight. Incorrect choices: B: fluid loss of 1.5 liters - This is incorrect because the weight increased, indicating fluid retention. C: equal intake and output due to insensible losses - This is incorrect as weight increased, showing an imbalance in intake and output. D: fluid loss of 0.5 liters - This is incorrect as the weight increased, indicating fluid retention, not loss.
