A nurse is caring for a 6-month-old infant who has acute vomiting and diarrhea. Which of the following manifestations should the nurse identify as an indication of moderate hypovolemia?
Capillary refill greater than 4 seconds
Bradycardia
Tachypnea
Lethargy
The Correct Answer is C
A. Capillary refill greater than 4 seconds: This indicates severe hypovolemia, not moderate.
B. Bradycardia: Bradycardia is uncommon in hypovolemia and may occur late as a sign of decompensation, especially in infants.
C. Tachypnea. Tachypnea is a compensatory response to hypovolemia as the body attempts to improve oxygenation and circulation.
D. Lethargy: While lethargy is a concerning sign, it is associated with more severe dehydration than moderate hypovolemia.

B. "Pull the pinna up and back during medication administration." For infants, the pinna should be pulled down and back to straighten the ear canal.
C. "Hyperextend the infant's neck during medication administration." Hyperextending the neck is unnecessary and may cause discomfort; a neutral position is sufficient.
