Question 1 of 5
Deficiency of which vitamin or mineral results in an inadequate inflammatory response?
Correct Answer: A
Rationale: A deficiency of vitamin A results in an inadequate inflammatory response. Vitamin A is essential for maintaining immune function and epithelial integrity, which are critical for an effective inflammatory response. Deficiencies of vitamins B1 and C impair collagen formation, necessary for wound healing, while a zinc deficiency leads to impaired epithelialization, affecting tissue repair rather than the inflammatory response.
Question 2 of 5
An occlusive dressing is applied to a large abrasion. This is advantageous because the dressing will accomplish what?
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.
Question 3 of 5
A toddler has a deep laceration contaminated with dirt and sand. Before closing the wound, the nurse should irrigate with what solution?
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.
Question 4 of 5
The nurse should know what about Lyme disease?
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.
Question 5 of 5
The school nurse is seeing a child who collected some poison ivy leaves during recess. He says only his hands touched it. What is the most appropriate nursing action?
Correct Answer: C
Rationale: Rinsing with cold running water within 15 minutes neutralizes urushiol, the oil causing poison ivy dermatitis, preventing it from bonding to the skin. Warm water is used after dermatitis develops, Burow's solution treats lesions, and antibacterial soap can spread urushiol by removing skin oils.
