RN HESI Exit Exam

Correct Answer: C

Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS). This level of osmolarity indicates severe dehydration and hyperosmolarity, putting the client at risk of complications like organ failure. Immediate intervention is crucial to address the dehydration and restore fluid balance. The other options, while important in the overall assessment of a client with HHS, do not directly indicate the severity of dehydration and hyperosmolarity seen with a high serum osmolarity level.

Correct Answer: D

Rationale: In Paget's disease, bone remodeling is affected, leading to increased risk for fractures. Therefore, the primary goal of client teaching should focus on reducing the risk for injury. Choices A and B are not directly related to the primary concern of Paget's disease, which is bone fractures. Choice C, promoting rest and sleep, is important for overall health but is not the priority when considering the specific risks associated with Paget's disease.

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: C

Rationale: Shortness of breath is most concerning in a client with left-sided heart failure as it indicates pulmonary congestion, requiring immediate intervention. Jugular venous distention (Choice A) is a sign of increased central venous pressure but is not as concerning as pulmonary congestion. Crackles in the lungs (Choice B) are common in heart failure due to fluid accumulation but are not as immediately concerning as severe shortness of breath. Peripheral edema (Choice D) is a manifestation of fluid retention in the body but is less indicative of acute pulmonary distress compared to shortness of breath.

Correct Answer: D

Rationale: The correct answer is to administer 50% dextrose IV push first. In hyperglycemic hyperosmolar syndrome, the main goal is to rapidly reduce blood glucose levels to prevent further complications. Administering dextrose intravenously can help reverse the effects of high blood glucose levels quickly. Administering intravenous fluids, monitoring urine output, and obtaining a blood glucose level are important interventions but are not the first priority in treating HHS. Administering 50% dextrose IV push takes precedence as it directly addresses the elevated blood glucose levels.
