Critical Care Nursing Questions

Correct Answer: A

Rationale: Rationale: A: Closing the patient's eyes and placing a pillow under the head is the first step in postmortem care to maintain dignity and prevent airway occlusion. B: Washing the body and changing clothes can be done later and is not the priority. C: Removing medical equipment can wait until after ensuring the patient's comfort. D: Confirming the death certificate is important but not the immediate first step in postmortem care.

Correct Answer: A

Rationale: The correct answer is A: a diet of 2500 to 3500 kcal per day. During hemodialysis, the patient loses nutrients and energy, so a high-calorie diet is necessary to maintain proper nutrition and energy levels. 2500-3500 kcal/day is a suitable range for a 100-kg patient. Choice B is incorrect because protein intake should be adequate to prevent malnutrition in hemodialysis patients, typically 1.2g/kg body weight/day. Choice C is incorrect as potassium intake should be restricted in hemodialysis patients due to impaired kidney function. Choice D is incorrect because fluid intake should be individualized based on the patient's fluid status and should not be limited to less than 500 mL per day.

Correct Answer: A

Rationale: The correct answer is A. The nurse should suggest that the father contact his spiritual leader for counseling. This option is appropriate as it recognizes the importance of spirituality in coping with difficult situations. It offers emotional support and guidance to the father and his son during a time of crisis. Option B is incorrect as the nurse sharing her own religious beliefs may not align with the father's beliefs, potentially causing confusion or discomfort. Option C is not the best intervention, as the doctor's role is primarily medical, and explaining the odds of survival may not address the emotional and spiritual needs of the family. Option D is also incorrect as leaving the father and son to grieve alone does not provide them with the necessary support and guidance during such a challenging time.

Correct Answer: B

Rationale: The correct answer is B: Mechanical ventilation via an endotracheal tube. In acute respiratory failure, especially in the setting of pneumonia and COPD, mechanical ventilation is often necessary to support breathing. Endotracheal intubation allows for precise control of airway patency, oxygenation, and ventilation. Emergency tracheostomy (choice A) is typically reserved for long-term ventilatory support. Noninvasive positive-pressure ventilation (choice C) may not provide sufficient support in severe cases. Oxygen via bag-valve-mask (choice D) may not be adequate for ventilatory support in acute respiratory failure.

Correct Answer: D

Rationale: The correct answer is D because inflating the cuff until a slight leak is heard only at peak inflation ensures it is adequately sealed but not overinflated, preventing complications like tracheal injury or pressure necrosis. Choice A lacks specificity and can lead to overinflation. Choice B may result in overinflation as the firmness of the balloon is subjective. Choice C relies on a specific pressure reading, which may vary based on factors like tube size and patient anatomy, potentially leading to under- or overinflation.
