1. When does dehydration begin to occur?

Correct answer: C

Rationale: Dehydration leads to a decrease in the body's fluid levels, causing the salivary glands to produce less saliva, resulting in a dry mouth. Therefore, when dehydration begins to occur, salivary secretions decrease. Choice A is incorrect because the body does not reduce fluid output to zero during dehydration; it tries to conserve fluids. Choice B is incorrect as dehydration does not directly increase the release of ANH (Atrial Natriuretic Hormone). Choice D is incorrect because salivary secretions do not increase but decrease during dehydration.

2. A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?

Correct answer: D

Rationale: The correct answer is to 'dangle the client on the bedside before ambulating.' This intervention helps prevent orthostatic hypotension, a drop in blood pressure when changing positions, which is crucial in preventing falls and related injuries in older adult clients. Asking family members to speak quietly (Choice A) may help keep the client calm but does not directly address the risk of injury. Assessing urine parameters (Choice B) is important for monitoring hydration status but does not specifically prevent injury. Encouraging increased fluid intake (Choice C) is essential for managing dehydration but does not directly address the risk of injury during ambulation.
