Critical Care Nursing Exam Questions Questions

Question 1 of 5

When preparing to cool a patient who is to begin therapeutic hypothermia, which intervention will the nurse plan to do (select all that apply)?

Correct Answer: C

Rationale: Rationale: Continuous cardiac monitoring is crucial during therapeutic hypothermia to monitor the patient's cardiac rhythm and detect any arrhythmias promptly. This intervention allows for immediate intervention if any cardiac issues arise. Explanation of other choices: A: Assisting with endotracheal intubation may be necessary for airway management but is not directly related to cooling the patient for therapeutic hypothermia. B: Inserting an indwelling urinary catheter may be needed for urine output monitoring but is not a priority intervention for cooling the patient. D: Restraining the patient is unnecessary and not indicated for therapeutic hypothermia; it may cause unnecessary distress and should be avoided unless absolutely necessary for patient safety.

Question 2 of 5

The nurse is caring for a patient with acute kidney injury who is being treated with hemodialysis. The patient asks if he will need dialysis for the rest of his life. Which of the following would be the best response?

Correct Answer: D

Rationale: The correct answer is D: �Recovery is possible, but it may take several months.� This response is the best choice as it provides a balanced and accurate explanation to the patient. Here's the rationale: 1. Hemodialysis is often used as a temporary measure to support kidney function while allowing time for the kidneys to recover. 2. Acute kidney injury can be reversible in some cases, especially if the underlying cause is identified and treated promptly. 3. Recovery time varies for each individual, and it can indeed take several months for kidney function to improve. 4. Choices A, B, and C are incorrect: - A is overly pessimistic and does not consider the potential for recovery. - B provides a specific timeframe that may not be accurate for all patients. - C is not a reliable indicator of kidney function recovery and may lead to confusion.

Question 3 of 5

Intrapulmonary shunting refers to what outcome?

Correct Answer: C

Rationale: Step-by-step rationale for why choice C is correct: 1. Intrapulmonary shunting refers to blood bypassing the normal oxygenation process in the lungs. 2. Choice C describes blood being shunted from the right side of the heart (deoxygenated blood) to the left side without oxygenation, leading to systemic circulation without oxygenation. 3. Choices A, B, and D do not accurately describe intrapulmonary shunting as they focus on other concepts like alveolar perfusion, heart failure, and unilateral lung blood supply, respectively.

Question 4 of 5

The nurse is caring for 80-year-old patient who has been tr eated for gastrointestinal bleeding. The family has agreed to withhold or withdraw additional treatment. The patient has a written advance directive specifying requests. The directive notes that the patient wants food and fluid to be continued and to be made physically comfortable. Th e nurse anticipates that several orders may be written to comply with this request, including which of the following? (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A: "Do not resuscitate." In this scenario, the patient's advance directive specifies a desire for comfort measures and continuation of food and fluids. A DNR order aligns with this directive by respecting the patient's wish to avoid aggressive life-saving measures. This choice prioritizes the patient's autonomy and quality of life. Other options (B, C, D) are not aligned with the patient's wishes. Changing antibiotics or stopping blood transfusions may be unrelated to the patient's comfort or food/fluid preferences. Discontinuing tube feeding goes against the directive's request for food and fluid continuation.

Question 5 of 5

The family members are excited about being transferring t heir loved one from the critical care unit to the intermediate care unit. However, they are also fearful of the change in environment and nursing staff. To reduce relocation stress, the nurse ca n implement what intervention? (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A (Arranging for the nurses on the intermediate care unit to give the family a tour of the new unit) because it helps familiarize the family with the new environment, alleviating their fears. The tour allows them to see where their loved one will be cared for, meet the nursing staff, and ask any questions they may have. This intervention promotes a smooth transition, reduces anxiety, and builds trust. Choice B is incorrect because delaying the transfer doesn't address the fear of change and can prolong stress. Choice C is incorrect as proximity to the nurse's station may not necessarily reduce relocation stress for the family. Choice D is incorrect because meeting the new nurse in the current unit may not provide the same level of comfort and preparation compared to physically visiting the new unit.
