ATI Fluid and Electrolytes

1. Which electrolyte is important in the formation of the thyroid hormones?

Correct answer: B

Rationale: Iodine is the correct answer because it is essential for the synthesis of thyroid hormones. The thyroid gland incorporates iodine into thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are crucial for regulating metabolism, growth, and development. Sodium, iron, and chloride are not directly involved in the formation of thyroid hormones, making them incorrect choices.

2. The baroreceptors, located in the left atrium and in the carotid and aortic arches, respond to changes in the circulating blood volume and regulate sympathetic and parasympathetic neural activity as well as endocrine activities.

Correct answer: D

Rationale:

3. Which condition can result from prolonged vomiting or diarrhea?

Correct answer: C

Rationale: The correct answer is C: Dehydration. Prolonged vomiting or diarrhea can lead to significant fluid loss, causing dehydration.

Electrolytes (choice D) are minerals that help maintain fluid balance in the body but are not the condition directly resulting from prolonged vomiting or diarrhea.
