الإجابة: D. Nasopharyngeal swab for SARS-CoV-2 PCR
A febrile respiratory illness after close contact with a confirmed COVID-19 case needs confirmation by nasopharyngeal swab PCR - viral respiratory infections are investigated by nasopharyngeal PCR, and COVID-19 is only distinguishable (e.g. from MERS) by PCR. Antibody tests are not the diagnostic test for acute infection, CT is not for everyone, oseltamivir treats influenza, and sending her home untested is unsafe.

A
ليش غلط
Oseltamivir is the antiviral for influenza (diagnosed by a rapid antigen test). The question asks for the next step to confirm a suspected COVID-19 case, not a treatment.

B
ليش غلط
Chest CT is indicated for an inconclusive chest X-ray or recurrent pneumonia, not for everyone. It does not confirm the virus.

C
ليش غلط
COVID-19 looks very similar to MERS and is only distinguishable by PCR, so antibody testing alone is not the way to diagnose an acute illness.

D
ليش صح
A febrile respiratory illness after contact with a confirmed case needs a nasopharyngeal swab PCR: COVID-19 is only distinguishable from similar viral pneumonias by PCR.

E
ليش غلط
A possible viral respiratory infection after a known contact should be investigated; the notes use nasopharyngeal PCR for viral investigation, so sending her home untested is wrong.
