HESI RN Exit Exam 2023 Capstone

Correct Answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

Correct Answer: B

Rationale: The best response for a client with schizophrenia experiencing auditory hallucinations is to acknowledge the client's feelings and ask what the voices are saying. This approach helps build rapport with the client, demonstrates empathy, and allows the nurse to assess the content of the hallucinations. Understanding the content is crucial to determine whether the client is at risk of harm. Encouraging the client to ignore the voices (Choice A) may invalidate their experience. Redirecting the conversation (Choice C) may not address the underlying issue of the hallucinations. Offering reassurance (Choice D) without understanding the content may overlook potential risks.

Correct Answer: B

Rationale: Oliguria, or decreased urine output, after surgery can indicate tubular necrosis due to hypoperfusion, which may require intervention to restore renal function. Choice A is incorrect as oliguria is not a normal finding after surgery. Choice C is incorrect because dehydration is less likely in this context compared to tubular necrosis. Choice D is incorrect as a urine output of 25 ml/hour is not expected after splenectomy and should raise concern for renal impairment.

Correct Answer: D

Rationale: The correct answer is D. A decrease in white blood cell count indicates that the infection is responding to treatment, making this the most objective indicator of improvement in a client with sepsis. Choices A, B, and C are subjective indicators and may not always directly correlate with the resolution of the underlying infection. While an increase in urine output, a client reporting feeling less fatigued, and a decrease in heart rate are positive signs, they are not as specific or directly related to the resolution of the infection as a decrease in white blood cell count.

Correct Answer: D

Rationale: The correct answer is D. Clients taking warfarin should avoid alcohol and over-the-counter medications without consulting their healthcare provider, as these can interact with warfarin and increase the risk of bleeding. Aspirin, in particular, can exacerbate this risk. Choice A is incorrect because taking warfarin with aspirin can increase the risk of bleeding. Choice B is incorrect as while green leafy vegetables contain vitamin K which can interact with warfarin, it is more important to maintain a consistent intake rather than increase it. Choice C is incorrect because foods high in potassium do not directly impact the bleeding risk associated with warfarin.
