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 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. There is no need to seal soft toys in a plastic bag for 14 days as impetigo is not typically spread through inanimate objects. However, it is important to discourage the child from scratching the lesions to prevent further spread.
B. Soaking hairbrushes in boiling water is not necessary for the management of impetigo.
Impetigo is caused by bacteria, not lice, so boiling hairbrushes is not a standard recommendation for this condition.
C. This is the correct instruction. Applying a bactericidal ointment (e.g., mupirocin) to the impetigo lesions is a common treatment approach. This helps to eliminate the bacteria causing the infection and promote healing.
D. Administering acyclovir is not indicated for impetigo. Acyclovir is an antiviral
medication used to treat viral infections, such as herpes simplex virus. Impetigo is caused by bacterial infection, not a virus.
Correct Answer is A
Explanation
A. This is the correct instruction. Varicella (chickenpox) is highly contagious. The child should be kept away from others until all lesions are crusted over and no new lesions have formed for at least 24 hours. This typically indicates that the child is no longer contagious.
B. Applying calamine lotion can help alleviate itching and discomfort associated with the vesicles. This is a supportive measure but does not address the contagious nature of the disease.
C. Dressing the child in warm clothing is not specific to the management of varicella. It is important to keep the child comfortable, but this instruction does not address the
contagious period.
D. It is generally safe to give the child a bath during varicella. Warm baths with mild soap can help soothe itching. However, the child should be dried gently to avoid breaking open any vesicles.
