Nursing Elites

1. When describing urticaria, what would an instructor include?

• A. It is a type IV hypersensitivity reaction.
• B. Histamine release leads to vasodilation.
• C. Wheals appear first followed by erythema.
• D. The nonpruritic rash blanches with pressure.

Correct answer: B

Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

2. A child is being assessed by a nurse for suspected nephrotic syndrome. What clinical manifestation is the nurse likely to observe?

• A. Jaundice
• B. Edema
• C. Hypertension
• D. Polyuria

Correct answer: B

Rationale: Edema is a hallmark clinical manifestation of nephrotic syndrome. In nephrotic syndrome, there is increased permeability of the glomerular filtration barrier, leading to protein loss in the urine (proteinuria). The decrease in serum protein levels results in a reduced oncotic pressure, leading to fluid shifting from the intravascular space into the interstitial spaces, causing edema. Jaundice (choice A) is not typically associated with nephrotic syndrome. Hypertension (choice C) is more commonly seen in conditions like nephritic syndrome. Polyuria (choice D) is excessive urination and is not a prominent feature of nephrotic syndrome.

3. After surgery to correct hypertrophic pyloric stenosis (HPS) in a 3-week-old infant who had been formula-fed, which postoperative feeding order is appropriate?

• A. Thickened formula 24 hours after surgery
• B. Withholding feedings for the first 24 hours
• C. Regular formula feeding within 24 hours after surgery
• D. Additional glucose feedings as desired after the first 24 hours

Correct answer: C

Rationale: After surgery for hypertrophic pyloric stenosis (HPS), it is appropriate to resume regular formula feeding within 24 hours postoperatively to promote recovery. Choice A, thickened formula after surgery, may be too heavy for the infant's digestive system at this early stage. Withholding feedings for the first 24 hours (Choice B) is not recommended as early feeding helps with recovery. Additional glucose feedings (Choice D) are not necessary and may not provide the balanced nutrition required after surgery.

4. A newborn is diagnosed with metatarsus adductus. The parents ask the nurse how this occurred. Which response by the nurse would be most appropriate?

• A. This condition is due to a genetic defect in the bones.
• B. It's most likely from how the baby was positioned in utero.
• C. They really don't know what causes this condition.
• D. There is probably an underlying deformity of the baby's hip.

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.

5. An infant is admitted to the neonatal intensive care unit (NICU) with exstrophy of the bladder. What covering should the nurse use to protect the exposed area?

• A. Loose diaper
• B. Dry gauze dressing
• C. Moist sterile dressing
• D. Petroleum jelly gauze pad

Correct answer: C

Rationale: In cases of exstrophy of the bladder, a moist sterile dressing is the most appropriate choice to protect the exposed bladder tissue. Moist sterile dressings help maintain a clean environment, prevent infection, and promote healing. A loose diaper (Choice A) may not provide adequate protection and may lead to contamination. Dry gauze dressing (Choice B) could adhere to the wound and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) is not ideal as it may not provide the necessary barrier against infection and could potentially cause irritation.
