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

Answer and Explanation

The Correct Answer is A

A. A respiratory rate of 28 breaths per minute indicates increased respiratory effort, which can be a sign of moderate dehydration. The infant may be trying to compensate for fluid
loss.

B. Capillary refill of 1 second is within the normal range (less than 2 seconds). It is not indicative of moderate dehydration.

C. Weight loss of 7% is a significant amount of weight loss and is indicative of severe dehydration, not moderate dehydration. Moderate dehydration is usually defined as 5- 10% weight loss.

D. Bradycardia (slow heart rate) is not typically associated with dehydration. In fact, tachycardia (fast heart rate) is a more common sign of dehydration.

Correct Answer is C

Explanation

A. Hypertension is not a typical finding in severe dehydration. In fact, dehydration often leads to decreased blood pressure.

B. Increased urine output is not a typical finding in severe dehydration. Dehydration leads to decreased urine output as the body tries to conserve fluids.

C. This is the correct answer. In severe dehydration, the body compensates by increasing the respiratory rate to try to maintain oxygen levels and remove excess carbon dioxide. This is a compensatory mechanism in response to metabolic acidosis, which can occur with dehydration.

D. A capillary refill of 2 seconds indicates normal perfusion. In severe dehydration, capillary refill may be prolonged, indicating poor perfusion.

A. "Your child's feet should be 3 to 6 inches off the ground when seated on the bicycle." B. "Your child should keep the bicycle at least 3 feet from the curb while riding in the street." C. "Your child should walk the bicycle through intersections." D. "Your child should ride the bicycle against the flow of traffic."

Correct Answer is B

Explanation

A. "Your child's feet should be 3 to 6 inches off the ground when seated on the bicycle." This instruction is not related to safety. Proper seat height is important for comfort and efficiency but does not directly impact safety.

B. This is the correct instruction. Maintaining a distance of at least 3 feet from the curb while riding in the street allows space for maneuvering and helps prevent collisions with obstacles or parked cars.

C. "Your child should walk the bicycle through intersections." This is a good safety practice. Walking the bicycle through intersections reduces the risk of accidents with other vehicles.

D. "Your child should ride the bicycle against the flow of traffic." This is incorrect.
Children should ride their bicycles in the same direction as traffic. Riding against traffic increases the risk of accidents.
