Question

question 5 of 85
a nurse is caring for an infant who has pertussis. which of the following actions should the nurse take?
obtain a stool culture.
administer oseltamivir.
initiate contact precautions.
administer azithromycin.

Explanation:

Pertussis (whooping cough) is caused by Bordetella pertussis. Azithromycin is an antibiotic effective against Bordetella pertussis. Stool culture is not relevant for pertussis diagnosis (usually nasopharyngeal swab). Oseltamivir is for influenza (not pertussis). Pertussis requires droplet precautions (not just contact precautions).

Answer:

Administer azithromycin.
