RN HESI Exit Exam

Correct Answer: C

Rationale: The INR should be closely monitored in a client prescribed warfarin (Coumadin) to assess the effectiveness and safety of anticoagulation therapy. Monitoring the INR helps determine if the client's blood is clotting appropriately. While prothrombin time (PT) is related to warfarin therapy, the INR is a more precise measure. Hemoglobin level and serum sodium level are not directly related to monitoring warfarin therapy.

Correct Answer: A

Rationale: Correct Answer: The nurse should first place the side rails in an up position. This action is crucial to prevent the client from falling while the bed is being made. Choice B is incorrect as moving or turning the client is not necessary at this point. Choice C is not a priority when immediate safety concerns are present. Choice D, asking the client if they are comfortable, though important, should come after ensuring the client's safety by raising the side rails.

Correct Answer: C

Rationale: A serum bicarbonate level of 18 mEq/L is most concerning in a client with COPD as it indicates metabolic acidosis, requiring immediate intervention. In COPD, patients often retain carbon dioxide, leading to respiratory acidosis. A low serum bicarbonate level suggests that the body is compensating for this respiratory acidosis by increasing bicarbonate levels to maintain balance. Therefore, a low serum bicarbonate level in this scenario is alarming. Choices A, B, and D are within normal ranges and not directly related to the acid-base imbalance seen in COPD.

Correct Answer: B

Rationale: Before a renal biopsy, the nurse should review the serum creatinine level. Serum creatinine is a key indicator of kidney function. In clients with chronic kidney disease (CKD), monitoring creatinine levels is crucial as elevated levels may indicate worsening kidney function, which could impact the safety and outcome of the biopsy. Hemoglobin (choice C) is important for assessing oxygen-carrying capacity but is not directly related to the kidney biopsy procedure. Serum potassium (choice A) is important to monitor in CKD but is not specifically crucial before a renal biopsy. White blood cell count (choice D) is more relevant for assessing infection or inflammation, which is not the primary concern before a renal biopsy.

Correct Answer: B

Rationale: Verifying whether the client has an executed living will is crucial to ensuring that his treatment preferences are followed. In this critical situation, knowing the client's wishes regarding medical interventions is paramount. Options A, C, and D are not the highest priority as they do not directly address the immediate need to determine the client's treatment preferences.
