The nurse is assisting a 4th-day postoperative cholecystectomy client in planning her meals for tomorrow's menu. Which vitamin is the most essential in promoting tissue healing?
- A. Vitamin C
- B. Vitamin B1
- C. Vitamin D
- D. Vitamin A
Correct Answer: A
Rationale: Vitamin C (ascorbic acid) is essential in promoting wound healing and collagen formation. Vitamin B1 (thiamine) maintains normal gastrointestinal (GI) functioning, oxidizes carbohydrates, and is essential for normal functioning of nervous tissue. Vitamin D regulates absorption of calcium and phosphorus from the GI tract and helps prevent rickets. Vitamin A is necessary for the formation and maintenance of skin and mucous membranes. It is also essential for normal growth and development of bones and teeth.
The postpartum nurse should include which of the following instructions to breast-feeding mothers?
- A. Limit feeding times for several days to avoid nipple soreness.
- B. Wash the nipples with soap and water before and after each feeding.
- C. Daily caloric intake should be increased by 500 cal.
- D. Breast milk is totally digestible by the baby because it contains lactose.
Correct Answer: C
Rationale: Limiting initial feeding times will only delay nipple soreness as well as the establishment of the letdown reflex, thus encouraging engorgement from clogged ducts and ductules. Soap should be avoided because it may be excessively drying, predisposing nipples to cracking. For optimal milk production, an additional 500 kcal over maintenance levels are needed daily. Lipase, not lactose, emulsifies the fat in breast milk, making it almost totally digestible by infants.

Correct Answer: A
Rationale: Nimodipine, a calcium channel blocker, prevents calcium influx into cells, reducing vasospasm post-aneurysm rupture. It doesn’t normalize BP (B), prevent inflammation (C), or dissolve clots (D).
