ATI Fluid and Electrolytes
1. When considering overhydration:
- A. occurs less often than dehydration.
- B. can strain the kidneys.
- C. can be caused by giving intravenous fluids too rapidly.
- D. less common than dehydration.
Correct answer: C
Rationale: The correct answer is C. Overhydration can occur when intravenous fluids are administered too quickly, overwhelming the body's ability to excrete the excess fluid. Choices A, B, and D are incorrect. Choice A is incorrect because overhydration is less common than dehydration. Choice B is incorrect because while overhydration can strain the kidneys, it is not due to the burden being too heavy. Choice D is incorrect because dehydration is more common than overhydration.
2. The nurse is caring for a patient who is diaphoretic from a fever. The amount of sodium excreted in the urine will:
- A. Decrease
- B. Increase
- C. Remain unchanged
- D. Fluctuate
Correct answer: A
Rationale: Increased sweating (diaphoresis) causes the loss of sodium and other electrolytes from the body. As a result, the body tries to conserve sodium, leading to a decrease in the amount of sodium excreted in the urine. Choice B is incorrect because increased sweating results in sodium loss, not retention. Choice C is incorrect because with increased sweating, there is a need to conserve sodium, leading to a decrease in its excretion. Choice D is incorrect as there is a clear physiological response to sweating that results in a more consistent decrease in sodium excretion.

- A. Hypertension
- B. Kussmaul respirations
- C. Increased DTRs
