Final answer:
For a 15-month-old child in a clinic, a nurse should administer the DTaP vaccine according to the CDC's recommended schedule, assuming there are no contraindications such as a moderate or severe illness with fever.
Step-by-step explanation:
Nurse's Actions for a 15-Month-Old Child:
A nurse is caring for a 15-month-old child in a clinic and has several vaccine options for the child's age. The CDC recommends children receive doses of the DTaP vaccine at 2, 4, 6, and 15-18 months of age. Therefore, one of the actions the nurse should take is to administer the DTaP vaccine, as long as the child does not have any contraindications, such as a moderate or severe illness with fever. Other vaccines listed, such as the rotavirus vaccine and the hepatitis A vaccine, follow different schedules.
The rotavirus vaccine should be administered in the first dose between six and 15 weeks of age and the second before 32 weeks, so it would not be applicable in this case if the child has already received it on schedule. Regarding holding immunizations until a fever subsides, this would be recommended if the child currently has a moderate or severe illness with a fever. The hepatitis A vaccine is also part of the pediatric immunization schedule but is not specifically timed around the 15-month mark.
