Question 16

A patient is intubated, is unable to follow simple commands, and has no history of alcohol abuse. The patient has become increasingly disoriented and confused over the past 24 hours. After assessment and treatment of pain, the best medication intervention for management is

Correct Answer: D
Dexmedetomidine (Precedex) is the most appropriate medication for managing agitation and delirium in a critically ill intubated patient. It provides sedation without significant respiratory depression and has analgesic properties, which makes it suitable for patients who are disoriented and confused. Unlike benzodiazepines (lorazepam and midazolam) or neuromuscular blockers (cisatracurium), dexmedetomidine can improve delirium outcomes and facilitates easier weaning from mechanical ventilation.

Question 17

After the administration of haloperidol (Haldol), a nurse should monitor closely for

Correct Answer: A

Haloperidol
Explore
Haloperidol has a known side effect of prolonging the QT interval, which can lead to cardiac dysrhythmias123. Therefore, after the administration of haloperidol, it is important for a nurse to monitor for a prolonged QT interval and cardiac dysrhythmias123. This is why continuous cardiac monitoring is recommended if repeated doses are given1.

Question 18

Assessment of a patient admitted with excruciating back pain reveals:

Appropriate therapy should include

Correct Answer: D
The patient's vital signs indicate hypertensive urgency or emergency (BP 190/100, HR 126), with a differential radial pulse, suggesting aortic dissection. Nitroprusside is a potent vasodilator used in the management of hypertensive crises and can help reduce blood pressure and the shear force on the aortic wall, which is crucial in managing aortic dissection. Nitroglycerin, diltiazem, and digoxin are not appropriate first-line therapies for this condition. References: AACN Adult CCRN Certification Review Course, AACN CCRN Exam Handbook.

Question 19

Treatment of cerebral vasospasm includes administration of

Correct Answer: C
Nimodipine is a calcium channel blocker that is used to prevent or treat cerebral vasospasm after subarachnoid hemorrhage. It works by relaxing the smooth muscle of the cerebral arteries and improving blood flow to the brain. Nimodipine is the only FDA-approved agent for vasospasm and has been shown to reduce the risk of ischemic complications and improve neurological outcomes12. Lorazepam, propranolol, and pentobarbital are not effective for treating cerebral vasospasm and may have adverse effects on the patient's blood pressure, heart rate, and level of consciousness.

Question 20

A patient with cardiogenic shock for several days has been managed aggressively with vasopressor and inotrope therapies. Which of the following indicates organ dysfunction from hypoperfusion?

Correct Answer: C
In the context of cardiogenic shock managed with vasopressor and inotrope therapies, organ dysfunction from hypoperfusion can manifest as elevated creatinine and abdominal pain. Elevated creatinine indicates renal impairment, a common result of poor perfusion to the kidneys. Abdominal pain can indicate hypoperfusion to the gastrointestinal tract, leading to ischemic bowel or other GI complications. These symptoms are direct indicators of hypoperfusion and organ dysfunction. References: = CCRN Exam Handbook, AACN Adult CCRN Certification Review Course
