A 60 year old lady presents with a skin tear to her left shin on her coffee table. She is unsure of her previous immunization status. How should this be managed?

Correct Answer: A

Rationale: For a minor, clean wound like a skin tear with unknown immunization status, ADT (tetanus toxoid) is sufficient if >10 years since last dose. Immunoglobulin is reserved for high-risk wounds.

Correct Answer: D

Rationale: Pneumococcus is more likely than TB in AIDS pneumonia in some settings, though TB is common globally.

Correct Answer: D

Rationale: Isolation precautions include standard (for all patients), transmission-based (for specific pathogens), and protective (e.g., for immunocompromised patients), making all options correct.

Correct Answer: B

Rationale: Gloves should overlap the gown cuff to prevent exposure of skin during PPE use.

Correct Answer: C

Rationale: Sterilization ensures complete destruction of all pathogens, unlike cleaning (removes debris) or disinfection (reduces pathogens), making C correct.
