A twenty-one-year-old man suffered a concussion, and the MD ordered an MRI. The patient asks, 'Will they allow me to sit up during the MRI?' The correct response by the nurse should be:

Correct Answer: D

Rationale: The correct answer is to inform the patient that they will have to lie down on their back during the MRI. This positioning is necessary for the scan to obtain accurate images of the brain. Choice A is incorrect because the decision on the positioning during the MRI is typically determined by the imaging protocol and not subject to negotiation during the test. Choice B is incorrect as the reverse Trendelenburg position is not commonly used during MRI scans. Choice C is incorrect because the radiologist does not usually make decisions on patient positioning during the MRI; it is predetermined by the imaging requirements.

Correct Answer: D

Rationale: When a patient's central venous access device (CVAD) becomes infected, administering antibiotics through the line is essential to attempt to eliminate microorganisms within the catheter. The goal is to prevent the necessity of removing the catheter, which might be required if the infection persists. Choice A, 'To prevent infiltration of the peripheral line,' is incorrect as the priority is addressing the catheter infection, not preventing issues with a peripheral line. Choice B, 'To reduce the pain and discomfort associated with antibiotic administration in a small vein,' is not relevant to the rationale for choosing the CVAD for antibiotic administration. Choice C, 'To lessen the chance of an allergic reaction to the antibiotic,' is also incorrect as the main focus is managing the catheter-associated infection rather than allergy prevention.

Correct Answer: C

Rationale: The mother is experiencing a situational crisis as the unexpected birth of a child with a cleft lip and palate has placed her in a challenging situation she did not anticipate. This type of crisis is triggered by specific events and circumstances. Choice A, reactive, implies responding to a stressor after it has occurred, which is not the case here. Choice B, maturational, refers to stress related to developmental stages, not to external events like the child's condition. Choice D, adventitious, involves crises resulting from events outside one's control, such as natural disasters, which do not apply in this scenario.

Correct Answer: A

Rationale: The correct answer is that survivors have greater emotional turmoil and shock than when death is expected. Sudden death produces more emotional turmoil and shock in survivors compared to gradual, expected death. Survivors of sudden death do not have the opportunity to engage in anticipatory grief. The unexpectedness of sudden death is the most disturbing and unbalancing factor, leading to heightened emotional turmoil and shock. Choice B is incorrect as survivors of sudden death experience more emotional turmoil and shock. Choice C is incorrect because sudden death brings about a different level of emotional turmoil and shock. Choice D is incorrect as survivors of sudden and unexpected death still go through significant emotional distress.

Correct Answer: C

Rationale: The correct answer is 'enterohepatic cycling.' This process involves drugs being excreted into bile, delivered to the intestines, reabsorbed into the circulation, and can prolong the drug's presence in the body. 'Hepatic clearance' (Choice A) refers to the amount of drug eliminated by the liver. 'Total clearance' (Choice B) is the sum of all types of clearance including renal, hepatic, and respiratory. 'First-pass effect' (Choice D) is the amount of drug absorbed from the GI tract and metabolized by the liver before entering circulation, reducing the amount of drug available for systemic circulation.
