HESI 799 RN Exit Exam Capstone

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: In a client experiencing a sudden drop in blood pressure after epidural anesthesia, the first action the nurse should take is to place the client in a lateral position. This position helps improve venous return and cardiac output by relieving aortocaval compression. Administering oxygen via nasal cannula may be necessary if the client shows signs of respiratory distress, but it is not the first priority in this situation. Administering an intravenous fluid bolus can help stabilize blood pressure, but repositioning the client takes precedence. Preparing the client for an emergency cesarean section is not indicated solely based on a sudden drop in blood pressure after epidural anesthesia; this step would be considered if other complications arise.

Correct Answer: D

Rationale: The first priority in an acute asthma exacerbation is to administer oxygen to improve the client's oxygen saturation. In this scenario, the client has a low oxygen saturation level of 86%, indicating hypoxemia, which can be life-threatening. Administering oxygen therapy will help improve oxygenation and support vital organ function. Once the oxygen levels are stabilized, further interventions such as bronchodilators can be implemented. Placing the client in a high-Fowler's position may also be beneficial, but ensuring adequate oxygenation takes precedence in this critical situation. Obtaining a peak flow reading is important for asthma management but is not the first intervention needed in a client with severe hypoxemia.

Correct Answer: A

Rationale: The correct answer is A: 'Limit fluid intake to prevent fluid overload.' Clients with advanced chronic kidney disease are at risk of fluid retention, which can lead to complications like fluid overload and hypertension. Therefore, it is crucial to instruct the client to limit fluid intake. Choice B is incorrect because increasing sodium intake can exacerbate fluid retention and hypertension in clients with CKD. Choice C is incorrect as increasing potassium intake can be dangerous for clients with CKD who may already have elevated potassium levels. Choice D is incorrect because while protein intake may need to be adjusted for clients on hemodialysis, the priority in this case is managing fluid intake.

Correct Answer: A

Rationale: The correct action for the nurse to implement is to check the client's glucose level with a glucometer. Constant hunger and thirst along with weight loss can be indicative of hyperglycemia, a possible side effect of saquinavir. Monitoring the client's glucose levels is crucial in this situation. Measuring the client's weight accurately (Choice B) is important for monitoring purposes but does not address the immediate concern of hunger, thirst, and weight loss. Reassuring the client that weight will stabilize as viral load decreases (Choice C) is not appropriate in this scenario as the symptoms described need immediate attention. Increasing the dose of saquinavir (Choice D) without assessing the client's glucose level can worsen the hyperglycemia.
