1. What is the most abundant positive ion in blood plasma?

Correct answer: C

Rationale: The correct answer is C: Sodium. Sodium (Na+) is the most abundant cation in the extracellular fluid, including blood plasma. It plays a crucial role in maintaining fluid balance, nerve function, and is essential for various physiological processes. Choice A, Potassium, is also an important ion in the body but is predominantly found intracellularly. Choice B, Calcium, is an essential mineral in the body but is not the most abundant positive ion in blood plasma. Choice D is incorrect as sodium is the primary positive ion in blood plasma, with a much higher concentration compared to potassium.

2. A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?

Correct answer: D

Rationale: The correct answer is to read food labels to determine sodium content. The client's sodium level is crucial to monitor as it is on the higher side (144 mEq/L), which can indicate hypernatremia. Excessive sodium intake can lead to fluid retention and other complications. Assessing dietary sodium intake can help the nurse and client make necessary adjustments to prevent further sodium imbalances. Choices A, B, and C are not the priority in this situation as the client's sodium level needs immediate attention to prevent potential complications.
