A 10-year-old patient presents with a 2.5-cm laceration on the right upper arm. Prior to suturing the laceration, the nurse practitioner should cleanse the wound with:
acetic acid 2% solution.
povidone-iodine solution.
chlorhexidine (Hibiclens).
saline solution for irrigation.
The Correct Answer is D
Rationale:
A. Acetic acid is primarily used for topical treatment of certain infections and is not appropriate for general wound cleansing before suturing.
B. Povidone-iodine can be irritating to tissues and may delay wound healing if used for deep wound irrigation.
C. Chlorhexidine (Hibiclens) is effective for skin antisepsis but is generally not recommended for open wound irrigation due to potential tissue toxicity.
D. Saline solution for irrigation is the preferred method for cleansing lacerations prior to suturing. It effectively removes debris and contaminants without causing tissue irritation, promoting optimal wound healing.

Correct Answer is B
Explanation
Rationale:
A. Metabolic acidosis may cause rapid breathing or lethargy but is not primarily indicated by fever.
B. In infants younger than 3 months, a temperature greater than 100.4°F (38°C) is concerning for a serious bacterial or viral infection due to their immature immune systems. Even mild fevers in this age group warrant prompt evaluation for sepsis, urinary tract infections, or meningitis.
C. Renal artery disease does not typically present with isolated fever in young infants.
D. Congenital heart defects may cause cyanosis, tachypnea, or poor feeding, but fever is not a primary sign.
Correct Answer is B
Explanation
Rationale:
A. A low-fiber diet is not a definitive treatment; dietary modifications may help manage symptoms but do not correct the underlying problem.
B. Surgical removal of the aganglionic segment of the bowel is the primary treatment for Hirschsprung’s disease, as the affected segment lacks nerve cells needed for normal peristalsis. Postoperative care may include temporary ostomy in some cases, but definitive management requires excision of the affected bowel.
C. A permanent colostomy is rarely needed; most children undergo a primary pull-through procedure.
D. Nasogastric decompression and supportive medical management do not resolve the underlying defect, though they may be used temporarily preoperatively to relieve obstruction.
