Before administering diphtheria, tetanus, and pertussis (DTaP) vaccine, the nurse should inform the infant's parents that which of the following reactions may develop?

A slight fever

Explanation

•Following immunization with DTaP, slight fever and pain at the injection site is possible. The nurse should instruct the mother to give acetaminophen.

•Artificially acquired, active immunity results from the use of ingested or injected vaccines, which are medically altered substances that stimulate the immune system to produce antibodies.

Incorrect options:

•A rash may be seen 7 to 10 days after the measles, mumps and rubella vaccine. 

•Redness and swelling at the injection site may occur immediately, but should resolve in a few hours.

•Symptoms of a respiratory infection are not associated with the DTaP vaccine.
