Question

Patients often request antibiotics when infected with a virus, like a cold or flu. Why is a medical professional justified in refusing to prescribe the patient antibiotics?

Antibiotics can weaken the immune system, allowing the virus to flourish in the body.

Antibiotics only target living things such as bacteria not viruses.

Antibiotics cause side effects that will only make the patient more ill and ultimately make the patient's recovery time longer.

Antibiotics create an environment that allows the viruses to continue to grow in the body

Answer 1

Correct answer: only statement 2 is justified.

Brief explanations:
- Statement 2 (true): Antibiotics target bacteria (and some other microbes) but do not work against viruses such as those that cause colds or flu. Giving antibiotics for a viral infection provides no benefit against the virus.
- Statement 1 (false/misleading): Antibiotics do not generally “weaken the immune system” in a way that lets viruses flourish. That’s not a standard reason to withhold them.
- Statement 3 (false/overstated): Antibiotics can cause side effects (nausea, allergic reactions, C. difficile infection, changes to the gut microbiome), so unnecessary use can harm patients, but it is not true that they will “only make the patient more ill” or always prolong recovery.
- Statement 4 (false): Antibiotics don’t create an environment that directly promotes viral growth.

Main justifications for refusing antibiotics for a viral illness: they are ineffective against viruses, they expose the patient to unnecessary risks and side effects, and overuse drives antibiotic resistance that harms both the patient and public health.
