HESI RN Exit Exam 2023 Capstone

Correct Answer: A

Rationale: When a client with diabetes mellitus presents with a high blood sugar level of 320 mg/dL, the nurse's initial action should be to administer sliding scale insulin as prescribed. The priority is to bring down the elevated glucose level promptly to prevent further complications. Encouraging the client to drink fluids or providing a carbohydrate snack would not effectively address the elevated blood sugar level in this scenario. Assessing for signs of hypoglycemia is not appropriate as the client's blood sugar level is high, not low.

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: C

Rationale: A serum creatinine level of 0.3 mg/dL is abnormally low, indicating potential issues with the interpretation of the creatinine clearance test. It is crucial for the nurse to notify the healthcare provider of this result before proceeding with the 24-hour urine collection. Checking urine output, instructing the client to increase fluid intake, or starting the urine collection without consulting the healthcare provider could lead to incorrect test results and misinterpretation of the client's renal function.

Correct Answer: C

Rationale: The correct answer is to instruct the client to use a disposable mask when in contact with others. TB is highly contagious, and wearing a mask can help prevent the spread of the disease to others. Choice A is important but not the priority as using a mask directly impacts public health. Choice B is related to a potential side effect of isoniazid, peripheral neuropathy, but immediate healthcare provider notification is not required. Choice D is relevant due to the potential hepatotoxicity of isoniazid and rifampin, but it is not the priority instruction in this scenario.

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.
