Correct Answer: A

Rationale: Cool compresses reduce swelling and pain from bee or wasp stings. Antibiotic cream is unnecessary unless infection occurs, warm compresses are not recommended, and corticosteroid cream is not part of initial treatment unless a severe reaction occurs.

Correct Answer: C

Rationale: Lyme disease is caused by Borrelia burgdorferi, a spirochete transmitted through a tick bite, leading to symptoms like erythema migrans. Prevention involves avoiding tick-infested areas and wearing protective clothing. It is not caused by mycotic spores, and while treatable with antibiotics, later stages may require more complex treatment.

Correct Answer: B

Rationale: Normal saline is the safest and most effective solution for irrigating open wounds as it cleans without causing tissue damage. Alcohol is too harsh, povidone-iodine is contraindicated for fresh wounds due to cytotoxicity, and hydrogen peroxide can cause subcutaneous gas formation under pressure.

Correct Answer: C

Rationale: Identifying and eliminating inappropriate eating habits is the core of behavior modification, addressing root causes of obesity. Cooking skills are secondary, peer relationships are not the focus, and normal weight is a long-term goal.

Correct Answer: C

Rationale: Occlusive dressings, such as Acuderm, maintain a moist environment that promotes healing by preventing dehydration of the wound bed and supporting cell migration. They do not deliver vitamin C, provide antiseptic properties, or promote friction, which could harm the wound.
