1. Which of the following are sources of water intake?

• A. Drinking fluids.
• B. Consuming water from the food we eat.
• C. Water from metabolic processes.
• D. Drinking fluids, consuming water from the food we eat, and water from metabolic processes.

Correct answer: D

Rationale: The correct answer is D. The sources of water intake include drinking fluids, consuming water from the food we eat, and water from metabolic processes. Water intake is not solely from the liquids we drink but also from the water content present in the food we consume and the water produced during metabolic processes such as cellular respiration. Therefore, option D is the correct answer as it covers all the sources of water intake. Options A, B, and C alone do not encompass all the sources of water intake, making them incorrect choices.

Rationale: The correct answer is C: hypernatremia. Hypernatremia refers to an elevated level of sodium in the blood, specifically when it is more than 145 mEq/L. Choice A, hyponatremia, is incorrect as it refers to low sodium levels. Choice B, hyperkalemia, is incorrect as it refers to high potassium levels, not sodium. Choice D, hypercalcemia, is also incorrect as it relates to elevated calcium levels, not sodium.
