Question 1 of 5
What behavior is the nurse most likely to assess in an adolescent with anorexia nervosa (AN)?
Correct Answer: C
Rationale: Individuals with AN are preoccupied with food, often preparing it for others or hoarding it while eating minimally. Secret eating and using food as a coping mechanism are typical of bulimia nervosa, and those with AN are aware of calorie intake?s impact.
Question 2 of 5
During the physical examination of an adolescent with significant weight loss, what finding may indicate an eating disorder?
Correct Answer: D
Rationale: Erosion of tooth enamel is a sign of bulimia nervosa due to repeated vomiting. Amenorrhea may occur in anorexia nervosa but is less specific, diarrhea relates to other conditions, and appetite suppression is not a physical exam finding.
Question 3 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 4 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 5 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.
