ATI Fluid Electrolyte and Acid-Base Regulation

1. After teaching a client to increase dietary potassium intake, a nurse assesses the client's understanding. Which dietary meal selection indicates the client correctly understands the teaching?

Correct answer: C

Rationale: Choice C is the correct answer as it includes foods high in potassium, such as raisins, whole wheat toast, and milk. Potassium is essential for various bodily functions, including maintaining proper heart and muscle function. Choices A, B, and D do not contain significant sources of potassium. Choice A consists mainly of carbohydrates and sugar, choice B focuses on protein and carbohydrates, and choice D provides carbohydrates and some fruit but lacks high-potassium options like in choice C.

2. Which mineral is important in hemoglobin production?

Correct answer: C

Rationale: Iron (Fe) is a critical mineral in hemoglobin production. Hemoglobin is a protein found in red blood cells that is essential for transporting oxygen throughout the body. Sodium (Choice A), Iodine (Choice B), and Chloride (Choice D) are not directly involved in hemoglobin production. Sodium is an electrolyte that helps maintain fluid balance, Iodine is essential for thyroid hormone production, and Chloride is an electrolyte that helps regulate fluid balance and acidity in the body.

3. Which of the following organs does not contribute to fluid output from the body?

Correct answer: D

Rationale: The correct answer is D. All the listed organs (lungs, skin, and intestines) contribute to fluid loss from the body. Lungs contribute to fluid loss through respiration, skin through sweating, and intestines through excretion. Therefore, none of the organs listed in the options retain fluids within the body. Choices A, B, and C are incorrect because all of these organs play a role in fluid output from the body.

4. 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.

5. A nurse is assessing a client with hypokalemia and notes that the client's handgrip strength has diminished since the previous assessment 1 hour ago. Which action should the nurse take first?

Correct answer: A

Rationale: In a client with hypokalemia experiencing diminished handgrip strength, the priority action for the nurse is to assess the client's respiratory rate, rhythm, and depth. Hypokalemia can lead to muscle weakness, including respiratory muscles, potentially causing respiratory distress. Assessing the respiratory status is crucial to determine if immediate interventions are needed to maintain adequate oxygenation. Measuring the client's pulse and blood pressure (Choice B) is important but should come after assessing the respiratory status. Simply documenting findings and monitoring the client (Choice C) may delay necessary interventions. Calling the healthcare provider (Choice D) is not the first action indicated in this situation; assessing the client's respiratory status takes precedence.
