HESI 799 RN Exit Exam Capstone

Correct Answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

Correct Answer: C

Rationale: For clients with peripheral artery disease, advising the client to take a short break when leg cramps occur and then continue walking is the appropriate intervention. This approach, known as interval walking, helps manage pain from intermittent claudication and improves circulation over time. Choice A is incorrect because immediate rest may not be necessary, and encouraging the client to resume walking after a short break is more beneficial. Choice B is incorrect since increasing potassium-rich foods may not directly address the underlying issue of peripheral artery disease causing cramps. Choice D is incorrect as avoiding walking altogether can lead to further deconditioning and worsen symptoms over time.

Correct Answer: C

Rationale: The correct answer is C: Monitor the client's partial thromboplastin time (PTT). During heparin therapy for DVT, it is essential to monitor the PTT to assess the effectiveness of the medication in preventing clot formation. Monitoring the PTT helps ensure that the client is within the therapeutic range for anticoagulation. Choices A, B, and D are incorrect because liver function tests, prothrombin time (PT), and red blood cell count are not specifically monitored to assess the effectiveness of heparin therapy in preventing clot formation.

Correct Answer: A

Rationale: Wernicke's encephalopathy is a neurological condition commonly caused by a deficiency in thiamine, often seen in clients with chronic alcohol abuse. Thiamine supplementation is the primary treatment to prevent further neurological damage. Folic acid replacement (choice B) is not the correct treatment for Wernicke's encephalopathy. Intravenous glucose (choice C) may be necessary in some cases of Wernicke's encephalopathy, but thiamine supplementation takes precedence. Magnesium sulfate administration (choice D) is not indicated as the primary treatment for Wernicke's encephalopathy.

Correct Answer: D

Rationale: The correct answer is D: "I need to get the client's written consent before I release any information to you." In this scenario, the nurse must obtain the client's written consent before disclosing any information to the social worker. This process ensures compliance with privacy laws like HIPAA, which are designed to protect client confidentiality. Choice A is incorrect because it does not address the need for consent. Choice B is incorrect as it is unprofessional and does not focus on obtaining consent. Choice C is incorrect as it suggests information can be shared without consent, which goes against privacy laws.
