A nurse is caring for an infant who has rotavirus.
Which of the following findings indicates that the infant is moderately dehydrated?
Respiratory rate 28/min.
Capillary refill 1 second.
Weight loss 7%.
Bradycardia.
The Correct Answer is C
A weight loss of 7% indicates that the infant is moderately dehydrated.
Dehydration is classified as mild (3-5% weight loss), moderate (6-10% weight loss), or severe (>10% weight loss)1.
Choice A is wrong because a respiratory rate of 28/min is within the normal range for an infant.
Choice B is wrong because a capillary refill time of 1 second is within the normal range.
Choice D is wrong because bradycardia (a slow heart rate) is not a typical sign of moderate dehydration in infants.

Correct Answer is C
Explanation
Bradycardia, or a slow heart rate, is a sign of digoxin toxicity in infants.
Digoxin is a medication used to improve the strength and efficiency of the heart and to control the rate and rhythm of the heartbeat.
However, an overdose can cause changes in the rate or rhythm of the heartbeat, including bradycardia.
Choice A is wrong because polyuria is not a sign of digoxin toxicity.
Choice B is wrong because diaphoresis is not a sign of digoxin toxicity.
Choice D is wrong because jaundice is not a sign of digoxin toxicity.
Correct Answer is B
Explanation
The nurse should first implement droplet precautions for the child.
Bacterial meningitis can be spread through respiratory and throat secretions, so it is important to take precautions to prevent the spread of infection.
Choice A is wrong because while a lumbar puncture may be necessary for diagnosis, preventing the spread of infection is a higher priority.
Choice C is wrong because while dimming the lights may provide comfort, preventing the spread of infection is a higher priority.
Choice D is wrong because while administering an antipyretic may provide comfort, preventing the spread of infection is a higher priority.
