Correct Answer: A

Rationale: The correct answer is A. Allowing the client to sit on the side of the bed before standing helps prevent dizziness and falls, especially during their first ambulation post-surgery. Choice B is incorrect because asking the client to take deep breaths when feeling dizzy may not address the underlying cause of the dizziness. Choice C is incorrect as it is unrelated to the task of assisting the client to ambulate for the first time. Choice D is incorrect because knowing how the client feels after sitting in the chair does not address the important step of assisting the client to stand up for the first time.

Correct Answer: A

Rationale: The correct answer is A: Administer insulin as prescribed. In clients with diabetes, high blood glucose levels can increase the risk of infection and impair healing after surgery. Administering insulin as prescribed helps reduce blood glucose to a safer level before surgery, preventing complications. Choice B is incorrect because delaying surgery without addressing the high blood glucose level does not address the immediate issue. Choice C is incorrect as checking the client's hemoglobin A1C level is not the priority when dealing with acute high blood glucose levels before surgery. Choice D is incorrect as administering IV fluids may help with hydration but does not directly address the high blood glucose level that needs immediate attention.

Correct Answer: A

Rationale: The correct answer is A: 'Take the medication with a full glass of water.' It is crucial for the nurse to teach the client to take ciprofloxacin with a full glass of water to prevent crystalluria, a potential side effect of the medication. Choice B is incorrect because ciprofloxacin does not require avoiding direct sunlight. Choice C is incorrect as taking the medication with meals is not necessary to prevent nausea. Choice D is incorrect as dizziness is not a common reason to discontinue ciprofloxacin.

Correct Answer: B

Rationale: The correct answer is to assess the client's endotracheal tube for obstruction. When a client on mechanical ventilation experiences high-pressure alarms, the first action should be to check for any potential obstructions in the airway, which can trigger the alarms. Checking the oxygen saturation (Choice A) is important but not the priority when dealing with high-pressure alarms. Repositioning the client (Choice C) may be necessary later but should not be the initial action. Suctioning the client's airway (Choice D) should only be done after assessing for and addressing any obstructions in the endotracheal tube.

Correct Answer: C

Rationale: In SIADH, there is excessive ADH secretion leading to water retention and dilutional hyponatremia. The most crucial intervention is to restrict fluid intake to prevent further fluid overload and worsening of hyponatremia. Encouraging oral hydration (choice A) would exacerbate the condition by adding more fluids. Monitoring for signs of dehydration (choice B) is not appropriate as the client is at risk of fluid overload. Administering IV fluids (choice D) would worsen the hyponatremia and should be avoided.
