Correct Answer: B

Rationale: Vertigo is the primary symptom of Meniere's disease and can lead to falls and other injuries. Ensuring safety and addressing the risk of injury is the nurse's top priority. While social isolation and impaired hearing are significant concerns associated with Meniere's disease, the immediate danger of falls due to vertigo takes precedence in the plan of care. Impaired verbal communication, although important, is not as urgent as preventing injuries caused by vertigo.

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 nurse's signature on a surgical consent form signifies that the client voluntarily grants permission for the procedure to be done. This is the correct answer because the nurse's signature does not imply the client's competence, understanding of risks and benefits, or that the client signed the form freely and voluntarily. The nurse's role is to verify that the client has made an informed decision and is providing consent for the procedure.

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: C

Rationale: The correct instruction for the nurse to include in the teaching for a client with GERD is to eat small, frequent meals throughout the day. This recommendation helps reduce symptoms by preventing the stomach from becoming overly full, which can increase pressure on the lower esophageal sphincter and lead to acid reflux. Choices A, B, and D are incorrect because increasing fluid intake with meals can exacerbate GERD symptoms, lying down after eating can worsen reflux, and consuming spicy foods can trigger acid reflux in individuals with GERD.
