Question

The nurse is aware that an antiviral medication is most effective when given during which phase of the infectious process?

A) Prodromal stage
B) Incubation period
C) Full stage of illness
D) Convalescent period

Answer 1

Antiviral medications are most effective when administered during the prodromal stage of the infectious process, as this is when the pathogen is actively replicating and initial symptoms appear.

Step-by-step explanation:

An antiviral medication is most effective when given during the prodromal stage (B) of the infectious process. During this phase, the pathogen multiplies and the host begins to experience general signs and symptoms of illness, indicating activation of the immune system. At this stage, the viral load in the body is sufficient for the antiviral agent to target and inhibit viral replication effectively, yet the full-blown symptoms of illness have not yet peaked. This is in contrast to antibiotics like penicillin being most effective during the log phase of bacterial growth. Thus, administering antiviral medications during the prodromal period can help control the infection and lessen the severity of the disease.
