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.

Correct Answer is D
Explanation
A. "I will breathe in through the mouthpiece, hold my breath for 5 seconds, and then exhale.": Incorrect because the child should exhale forcefully and quickly into the device, not inhale or hold their breath.
B. "If I get a reading in the green zone, I will tell my parents right away so they can call the doctor.": Incorrect because a green zone reading indicates controlled asthma, and no immediate action is required.
C. "I will slowly exhale through the mouthpiece over a 10-second interval.": Incorrect because the exhalation should be rapid and forceful to measure peak flow effectively.
D. "I will record the highest reading of the three attempts." Recording the highest reading ensures accurate monitoring of airway status and helps the child track their progress over time.
Correct Answer is D
Explanation
A. Administer IV antibiotics: While urgent, antibiotics can be administered after precautions are in place to ensure safety.
B. Monitor vital signs: Important but not the first action. Vital signs can be monitored after precautions are initiated.
C. Encourage oral fluids: Incorrect because IV fluids are usually required due to the severity of the illness and risk of shock.
D. Initiate droplet precautions. Protecting others from transmission is the highest priority in managing bacterial meningitis, a highly contagious condition.
