Answer 1

The Correct Option is D

Concept:
Drug hypersensitivity means an allergic reaction to a drug.

Step 1: Penicillin allergy can cause rash, urticaria, bronchospasm, or even anaphylaxis.

Step 2: If a patient has a history of hypersensitivity to penicillins, the same class should be avoided.

Step 3: Re-exposure may cause a more severe allergic reaction.

Step 4: Other antibiotics may be selected depending on infection and clinical condition.

Step 5: Therefore, penicillins should be avoided. \[ \boxed{\text{Penicillins}} \]
