Pediatric HESI 2024

Correct Answer: B

Rationale: Ensuring adequate hydration is crucial during a vaso-occlusive crisis in sickle cell anemia as it helps to reduce the viscosity of the blood and prevent further sickling of the cells. While administering oxygen may be necessary in some cases, ensuring hydration takes precedence as it directly impacts the underlying pathophysiology of the crisis. Monitoring vital signs is important for ongoing assessment but does not directly address the crisis as hydration does. Administering pain medication is important for pain relief but does not address the primary issue of vaso-occlusion and is not the most crucial intervention in this scenario.

Correct Answer: D

Rationale: Pegs and pounding boards are the most suitable choice for toddlers to express their emotions constructively. These materials provide a safe and acceptable way for toddlers to release anger and frustration through physical activity. Options A, B, and C may not be as effective or safe for toddlers dealing with temper tantrums. A ball and bat may encourage aggressive behavior rather than constructive expression. A wad of clay might not be ideal for channeling anger, and a punching bag can potentially promote violent behavior, which is not appropriate for toddlers.

Correct Answer: C

Rationale: In this scenario, the 21-year-old mother is showing signs of hemorrhagic shock with increased heart rate, diaphoresis, and vaginal bleeding. The appropriate management includes providing oxygen to support tissue perfusion, treating for shock to restore adequate circulation, and performing uterine massage to help control bleeding during transport. Options A, B, and D do not address the comprehensive management needed for postpartum hemorrhage in this situation.

Correct Answer: B

Rationale: Metatarsus adductus is a condition where the front part of the foot is turned inward. It is often caused by the baby's position in the womb, leading to pressure on the foot during fetal development. Choice A is incorrect as metatarsus adductus is not primarily caused by a genetic defect in the bones. Choice C is incorrect as the cause of metatarsus adductus is known to be related to intrauterine positioning. Choice D is incorrect as metatarsus adductus specifically pertains to the foot and not the hip.

Correct Answer: D

Rationale: Maintaining NPO (nothing by mouth) status is essential before surgery for a patient with Hirschsprung disease to prevent aspiration. Administering antibiotics, ensuring bowel rest, and performing regular enemas are not the priority interventions before surgery for this condition. Administering antibiotics may be necessary in the postoperative period to prevent infection, ensuring bowel rest can be beneficial but is not the priority, and performing regular enemas is not typically recommended before surgery for Hirschsprung disease.
