HESI RN Exit Exam 2023

Correct Answer: C

Rationale: The correct answer is C: Serum potassium of 3.2 mEq/L. A low serum potassium level in a client with DKA is concerning due to the risk of cardiac arrhythmias. Kussmaul respirations (choice A) are a compensatory mechanism for metabolic acidosis in DKA. A blood glucose level of 300 mg/dl (choice B) is elevated but expected in DKA. Positive urine ketones (choice D) are a classic finding in DKA and not as concerning as low serum potassium.

Correct Answer: A

Rationale: The correct action for the nurse to implement next is to collect a clean-catch specimen. This is essential to diagnose the cause of the client's symptoms accurately before initiating any treatment. Administering antibiotics (Choice B) without confirming the diagnosis through a specimen collection can be inappropriate and potentially harmful. Performing a bladder scan (Choice C) may not provide the necessary information to identify the specific cause of the symptoms. Increasing the client's fluid intake (Choice D) is a general recommendation and may not address the underlying issue causing the symptoms.

Correct Answer: B

Rationale: The correct answer is B: 'I should avoid eating foods high in potassium.' This statement indicates a misunderstanding as beta-blockers do not typically affect potassium levels. The other choices (A, C, and D) are all appropriate statements for a client prescribed a beta-blocker. Choice A shows understanding of the timing of medication administration, choice C addresses orthostatic hypotension concerns, and choice D highlights the importance of not abruptly stopping the medication to prevent adverse effects.

Correct Answer: C

Rationale: In this scenario, the best initial nursing action is to allow several minutes for the client to respond. This approach respects the cultural norms of the client, as in some cultures, direct eye contact may be perceived as disrespectful or intrusive. By giving the client time to gather his thoughts and respond at his own pace, the nurse promotes effective communication and demonstrates cultural sensitivity. Asking for assistance from social services to find a Korean interpreter (Choice A) may be necessary for further communication but is not the best initial action. Establishing indirect eye contact (Choice B) may still make the client uncomfortable. Repeating the question using simpler language (Choice D) may not address the underlying cultural aspect affecting the client's response.
