A nurse in an emergency department is caring for an infant who has a 2-day history of vomiting and an elevated temperature. Which of the following should the nurse recognize as the most reliable indicator of fluid loss?

A.

Blood pressure.

B.

Respiratory rate.

C.

Body weight.

D.

Skin integrity.

Answer and Explanation

The Correct Answer is C

Choice A rationale

 

Blood pressure is not the most reliable indicator of fluid loss in infants. Blood pressure can remain normal until dehydration is severe.

 

Choice B rationale

 

Respiratory rate can be affected by many factors and is not the most reliable indicator of fluid loss.

 

Choice C rationale

 

Body weight is the most reliable indicator of fluid loss in infants. A significant decrease in body weight indicates significant fluid loss and helps guide appropriate fluid replacement therapy.

 

Choice D rationale

 

Skin integrity can be affected by many factors and is not the most reliable indicator of fluid loss.
