Critical Care Nursing Exam Questions Questions

Question 1 of 5

An 80-year-old client is given morphine sulphate for postoperative pain. Which concomitant medication should the nurse question that poses a potential development of urinary retention in this geriatric client?

Correct Answer: B

Rationale: The correct answer is B: Tricyclic antidepressants. Tricyclic antidepressants can cause anticholinergic effects, including urinary retention, especially in the elderly. Morphine sulfate can also contribute to urinary retention. Antacids (A) and nonsteroidal anti-inflammatory agents (C) are not known to cause urinary retention. Insulin (D) does not pose a risk for urinary retention in this scenario.

Question 2 of 5

The nurse is concerned that a patient is at increased risk of developing a pulmonary embolus and develops a plan of care for prevention to include whic h intervention?

Correct Answer: D

Rationale: The correct answer is D: Mobility. Maintaining mobility helps prevent blood stasis, a leading factor in the development of pulmonary embolism. Movement promotes circulation, reducing the risk of blood clots. A: Antiseptic oral care is important for oral hygiene but not directly related to preventing pulmonary embolism. B: Bed rest with head of bed elevated can actually increase the risk of clots due to immobility. C: Coughing and deep breathing are beneficial for preventing respiratory complications but do not address the underlying cause of pulmonary embolism.

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

Complications common to patients receiving hemodialysis for acute kidney injury include which of the following? (Select all that apply.)

Correct Answer: A

Rationale: The correct answer is A, hypotension. During hemodialysis for acute kidney injury, fluid removal can lead to hypotension due to rapid changes in blood volume. This can cause dizziness, weakness, and even loss of consciousness. Dysrhythmias (choice B) are less common but can occur due to electrolyte imbalances. Muscle cramps (choice C) may occur during or after dialysis due to electrolyte imbalances or fluid shifts, but they are not as common as hypotension. Hemolysis (choice D) is not a common complication of hemodialysis for acute kidney injury, as it is more commonly associated with issues related to the dialysis machine or blood tubing.

Question 5 of 5

During the primary survey of a patient with severe leg trauma, the nurse observes that the patient’s left pedal pulse is absent and the leg is swollen. Which action will the nurse take next?

Correct Answer: B

Rationale: The correct answer is B: Assess further for a cause of the decreased circulation. The nurse should prioritize assessing the cause of the absent left pedal pulse and leg swelling to address the severe leg trauma effectively. This step involves identifying potential vascular compromise or compartment syndrome, which are critical conditions requiring immediate intervention. Sending blood for a complete blood count (A) is not the priority in this situation. Finishing the primary survey (C) may delay addressing the circulation issue. Starting normal saline infusion (D) without addressing the circulation problem first could potentially worsen the condition. Therefore, assessing further for the cause of decreased circulation is the most appropriate next step to ensure timely and appropriate management of the patient's condition.
