8) A 34-year-old California man in otherwise good health presents with coughing spasms followed by post-tussive emesis for three weeks. A nasopharyngeal swab was collected and the culture came back positive for a gram negative aerobic extracellular coccobacillis.

According to the Centers for Disease Control and Prevention, which one of the following is the best next step?

A) Prescribe inhaled albuterol
B) Do not prescribe antibiotics for the patient until culture results are available
C) Administer whole-cell pertussis vaccine
D) Treat close household contacts with antibiotics
E) Strict isolation of patient

Explanation will be posted soon....

pertussis consists of 3 stages;catarrhal,paroxismal and convalescent stage;
catarrhal stage is most contagious stage but unfortunately disease isn't diagnosed in this stage in most cases, but if diagnosed ,erythromycin will treat the patient.
erythromycin won't treat patient at paroxismal stage,however we prescribe antibiotic for both patient and persons in contact with him/her for preventing transmit of disease so if the option ;
"prescribe antibiotic for patient" would be among responses,you could choose it too.
with this comment "D" is correct answer.
