Question 1 of 5

Question 3 of 5

A nurse is visiting an 84-year-old woman living at home and recovering from hip surgery. The woman seems confused and has poor skin turgor, and she states that 'she stops drinking water early in the day because it is too difficult to get up during the night to go to the bathroom.' The nurse explains to the woman that:

Correct Answer: B

Rationale: The correct answer is B. In elderly patients, fluid deficits can lead to confusion and cognitive impairment. Limiting fluids can disrupt the body's balance, leading to such symptoms. Adjusting the timing of fluids can help maintain hydration without causing nighttime interruptions. Choices A, C, and D are incorrect because they do not address the underlying issue of fluid imbalance causing confusion. Choice A suggests unnecessary hospital readmission and medication adjustments. Choice C incorrectly normalizes confusion post-surgery and suggests it is safe not to urinate at night, which can exacerbate the issue. Choice D inaccurately attributes confusion to sleep loss rather than fluid imbalance.

In respiratory acidosis and most cases of metabolic acidosis, the kidneys excrete hydrogen ions and conserve bicarbonate ions to help restore balance.
