RN HESI Exit Exam

Correct Answer: B

Rationale: The most important intervention for the nurse to implement is to schedule weekly home visits to draw hCG values. Monitoring hCG levels is crucial in detecting potential complications like choriocarcinoma following GTD evacuation. Teaching about home pregnancy tests (Choice A) may not be as immediate and critical as monitoring hCG levels. A 5-week follow-up appointment (Choice C) may be too delayed for close monitoring. Initiating chemotherapy (Choice D) without appropriate hCG monitoring and evaluation is not recommended as the first-line intervention.

Correct Answer: A

Rationale: The correct answer is A. Frequent use of magnesium-containing laxatives can lead to hypermagnesemia, particularly in elderly clients. Option B, dietary intake of magnesium-rich foods, may contribute to elevated serum magnesium levels but is less likely the cause in this scenario. Option C, the use of magnesium-containing supplements, can also contribute to hypermagnesemia but is not as common in elderly clients without a history of using such supplements. Option D, history of alcohol use, is less relevant to the development of elevated serum magnesium levels compared to laxative use for chronic constipation.

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: Administering oxygen therapy is the priority intervention for a client with chronic heart failure presenting with shortness of breath and crackles in the lungs. Oxygen therapy helps improve oxygenation, which is crucial in managing respiratory distress. Loop diuretics (Choice B) may be indicated to manage fluid overload in heart failure but are not the immediate priority in this case. Administering morphine (Choice C) is not the first-line intervention for shortness of breath in heart failure and should be considered after addressing oxygenation and underlying causes. Obtaining an arterial blood gas sample (Choice D) can provide valuable information but is not the initial action needed to address the client's acute respiratory distress.

Correct Answer: C

Rationale: A serum ammonia level of 80 mcg/dL is most concerning in a client with cirrhosis as it may indicate hepatic encephalopathy, requiring immediate intervention. High serum ammonia levels can lead to altered mental status, confusion, and even coma. Serum albumin (choice A) is often decreased in cirrhosis but does not require immediate intervention. Serum bilirubin (choice B) elevation is expected in cirrhosis and may not require immediate intervention unless very high. Serum sodium (choice D) within the given range is generally acceptable and does not require immediate intervention.
