ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is caring for a client who has just had a central venous access line inserted. Which action should the nurse take next?

A. Begin the prescribed infusion via the new access
B. Ensure an x-ray is completed to confirm placement.
C. Check medication calculations with a second RN.
D. Make sure the solution is appropriate for a central line

Correct answer: B

Rationale:

2. A nurse is caring for an older adult client who is admitted with moderate dehydration. Which intervention should the nurse implement to prevent injury while in the hospital?

A. Ask family members to speak quietly to keep the client calm.
B. Assess urine color, amount, and specific gravity each day.
C. Encourage the client to drink at least 1 liter of fluids each shift.
D. Dangle the client on the bedside before ambulating.

Correct answer: D

Rationale: The correct answer is to 'dangle the client on the bedside before ambulating.' This intervention helps prevent orthostatic hypotension, a drop in blood pressure when changing positions, which is crucial in preventing falls and related injuries in older adult clients. Asking family members to speak quietly (Choice A) may help keep the client calm but does not directly address the risk of injury. Assessing urine parameters (Choice B) is important for monitoring hydration status but does not specifically prevent injury. Encouraging increased fluid intake (Choice C) is essential for managing dehydration but does not directly address the risk of injury during ambulation.

3. What is the most important regulator of the amount of sodium in the body?

A. Kidneys
B. Small intestine
C. Large intestine
D. Skin

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys play a crucial role in regulating the amount of sodium in the body. They achieve this by filtering blood and controlling the excretion or reabsorption of sodium. The small intestine is primarily responsible for nutrient absorption, not sodium regulation. The large intestine is mainly involved in water absorption and waste elimination, not sodium balance. The skin helps regulate body temperature through sweating and does not directly regulate sodium levels.

4. Which hormone reduces the amount of water in the body?

A. ADH
B. aldosterone
C. ANH
D. ADH and aldosterone

Correct answer: B

Rationale: The correct answer is 'aldosterone.' Aldosterone is the hormone that reduces the amount of water in the body by increasing the reabsorption of sodium and water from the kidney tubules. ANH (atrial natriuretic hormone) actually works to increase the excretion of sodium and water by the kidneys, leading to a reduction in blood volume and pressure. ADH (antidiuretic hormone) works to increase water reabsorption by the kidneys, thereby increasing blood volume. Therefore, choices A (ADH) and D (ADH and aldosterone) are incorrect in the context of reducing the amount of water in the body.
