4. What percentage of body water can be as high as in a newborn?

Correct answer: A

Rationale: The correct answer is A: 80%. Newborns can have a body water content as high as 80% due to their higher total body water compared to adults. Choice B (70%) is incorrect because newborns typically have a higher body water percentage. Choice C (60%) is also incorrect as it underestimates the body water content in newborns. Choice D (90%) is incorrect as it overestimates the body water percentage in newborns.

5. The nurse is caring for a patient who is diaphoretic from a fever. The amount of sodium excreted in the urine will:

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.
