- A. Cool compresses
- B. Antibiotic cream
- C. Warm compresses

Deficiency of which vitamin or mineral results in an inadequate inflammatory response?
- A. A
- B. B1
- C. C
- D. Zinc
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.
During the physical examination of an adolescent with significant weight loss, what finding may indicate an eating disorder?
- A. Diarrhea
- B. Amenorrhea
- C. Appetite suppression
- D. Erosion of tooth enamel
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.
A 6-year-old boy with very fair skin will be joining his family during a beach vacation. What should the nurse recommend?
- A. Keep him off the beach during the daytime hours.
- B. Use sunscreen with an SPF of at least 15 and reapply it every 2 to 3 hours.
- C. Apply a topical sunscreen product with an SPF of 30 in the morning.
- D. Dress him in long pants and long-sleeved shirt and keep him under a beach umbrella.
Correct Answer: B
Rationale: Sunscreen with SPF 15 or higher, reapplied every 2-3 hours and after water exposure, protects fair skin from UV damage. Avoiding the beach is impractical, a single SPF 30 application is insufficient, and long clothing with an umbrella is less practical than sunscreen.
Parents phone the nurse and say that their child just knocked out a permanent tooth. What should the nurses instructions to the parents include?
- A. Place the tooth in a dry container for transport.
- B. Hold the tooth by the crown and not by the root area.
- C. Transport the child and tooth to a dentist within 18 hours.
- D. Take the child to hospital emergency department if his or her mouth is bleeding.
Correct Answer: B
Rationale: Holding the tooth by the crown prevents damage to the root, which is critical for reimplantation. The tooth should be kept moist in milk or saline, seen by a dentist immediately, and bleeding is expected but not the primary reason for emergency care.
