A nurse is caring for an infant who has rotavirus. Which of the following findings indicates that the infant is moderately dehydrated?

A. Absent nuchal rigidity is a positive sign in the context of managing bacterial
meningitis, but it alone does not determine when droplet precautions can be discontinued.

B. This is the correct answer. A negative cerebrospinal fluid (CSF) culture indicates that the bacterial infection has been effectively treated. Once the CSF culture is negative, the child is no longer considered contagious and can be removed from droplet precautions.

C. The initiation of antibiotics is an important step in treating bacterial meningitis, but the passage of time alone does not indicate when precautions can be discontinued. The
effectiveness of treatment is better determined by laboratory and clinical indicators.

D. The temperature is an important clinical parameter, but a temperature below 37.4° C (99.3° F) alone does not determine when droplet precautions can be discontinued. The decision is based on the resolution of the infectious process, as indicated by negative cultures.

A. Rotavirus vaccine is not typically indicated for adolescents. It is usually administered to infants.

B. Correct. Adolescents with sickle cell anemia are at increased risk for infections,

including those caused by Streptococcus pneumoniae. The pneumococcal conjugate vaccine (PCV) helps protect against certain types of pneumococcal bacteria.

C. The MMR vaccine provides immunity against measles, mumps, and rubella, but it is not specifically indicated for adolescents with sickle cell anemia. They should receive
this vaccine as recommended for their age group.

D. The RSV vaccine is primarily recommended for infants and young children at high risk for severe respiratory syncytial virus (RSV) infection. It is not typically indicated for adolescents with sickle cell anemia.
