Critical Care Nursing NCLEX Questions

Correct Answer: A

Rationale: The correct answer is A: contact the provider and expect a prescription for a normal saline bolus. The patient is showing signs of hypovolemia with decreased urine output, low blood pressure, and elevated heart rate. This indicates inadequate perfusion and potential hypovolemic shock. Administering a normal saline bolus will help restore intravascular volume and improve perfusion. Waiting for the provider to make rounds (option B) could delay necessary intervention. Continuing to evaluate urine output for 2 more hours (option C) is not appropriate given the patient's current condition. Ignoring the urine output (option D) is dangerous as it could lead to further complications.

Correct Answer: A

Rationale: The correct answer is A: Agitation. In hyperactive delirium, patients often exhibit restlessness, agitation, and hyperactivity. This behavior is a key characteristic indicating hyperactive delirium. Apathy (B), biting (C), and hitting (D) are not typically associated with hyperactive delirium. Apathy may be seen in hypoactive delirium, while biting and hitting are not specific indicators of delirium subtypes. Therefore, the correct choice is A as it aligns with the typical presentation of hyperactive delirium.

Correct Answer: B

Rationale: The correct answer is B: Assist with the intubation of the patient. In this scenario, the patient is unconscious and has ingested a potentially harmful substance. Intubation is the first priority to maintain the patient's airway and ensure adequate oxygenation. This step is crucial in preventing aspiration of gastric contents and securing the patient's respiratory status. Inserting a large-bore orogastric tube (choice A) is not the priority as airway management takes precedence. Preparing a syringe with saline (choice C) is unnecessary at this stage. Giving the first dose of activated charcoal (choice D) should only be done after securing the airway to prevent aspiration.

Correct Answer: B

Rationale: The correct answer is B because assessing the hemofilter every 6 hours for clotting is essential in ensuring the effectiveness of CRRT. Clotting can obstruct blood flow, leading to treatment inefficiency and potential harm to the patient. This step helps the nurse to promptly address any clotting issues and prevent complications. A: Assessing that the blood tubing is warm to the touch is not a standard practice for monitoring CRRT and does not provide relevant information about the treatment's effectiveness. C: Covering the dialysis lines to protect them from light is not a priority in monitoring CRRT. Light exposure is not a common concern in this context. D: Using clean technique during vascular access dressing changes is important for infection prevention but is not directly related to monitoring the effectiveness of CRRT.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): When the low-pressure alarm sounds for a patient with an arterial line, the nurse should assess for cardiac dysrhythmias first. This is because a sudden drop in pressure could indicate a serious issue affecting the heart's ability to pump effectively. Identifying and addressing any cardiac dysrhythmias promptly is crucial for patient safety. Summary of Incorrect Choices: A: Fast flush of the arterial line - This would not address the underlying cause of the low-pressure alarm and may not be necessary. B: Check the left hand for pallor - While assessing perfusion is important, it is not the priority when the alarm indicates a potential cardiac issue. D: Rezero the monitoring equipment - While important for accuracy, it is not the priority when the alarm indicates a potential cardiac concern.
