Questions: Question 3 Which side effect commonly occurs while taking antibacterial agents? Hives Facial swelling Heart palpitations Gastrointestinal disturbances

The answer is the fourth one: Gastrointestinal disturbances.

Explanation for each option:

1. Hives: While hives can occur as an allergic reaction to some antibacterial agents, they are not the most common side effect. Allergic reactions are less frequent compared to gastrointestinal issues.

2. Facial swelling: Similar to hives, facial swelling can be a sign of an allergic reaction, which is not as common as gastrointestinal disturbances when taking antibacterial agents.

3. Heart palpitations: This is not a typical side effect associated with antibacterial agents. Heart palpitations are more commonly linked to other types of medications.

4. Gastrointestinal disturbances: This is the most common side effect of antibacterial agents. These disturbances can include nausea, vomiting, diarrhea, and abdominal pain, as antibiotics can disrupt the normal flora of the gut.

In summary, gastrointestinal disturbances are the most commonly reported side effect when taking antibacterial agents.
