Pediatric HESI 2023

Correct Answer: D

Rationale: The correct answer is D: Side-lying. After surgery using steel bar placement to correct pectus excavatum, the nurse should instruct the parents to avoid placing the child in a side-lying position. This position should be avoided to prevent displacement of the steel bar. Choices A, B, and C are incorrect. Semi-Fowler, Supine, and High Fowler positions are generally safe and commonly used in postoperative care, but in this specific case, side-lying should be avoided to ensure the effectiveness of the surgical correction.

Correct Answer: A

Rationale: The American Academy of Pediatrics recommends the intramuscular polio vaccine because it has a better safety profile compared to the oral vaccine. Choice B is incorrect because the AAP specifically recommends the intramuscular vaccine over the oral vaccine. Choice C is incorrect as cost is not the primary reason for preferring the intramuscular vaccine. Choice D is incorrect as the recommendation is based on safety rather than the immunocompromised status of the infant or family members.

Correct Answer: B

Rationale: The correct answer is "B: Rolls over." At 6 months, most infants can roll over, which increases the risk of falls. Emphasizing the infant's ability to roll over is crucial to highlight the need for careful supervision and accident prevention. Choices A, C, and D are incorrect because sitting up, crawling short distances, and standing while holding on to furniture typically develop later in an infant's motor skills progression and are not as directly associated with an increased risk of accidents at this stage.

Correct Answer: D

Rationale: After undergoing surgery for pectus excavatum correction with steel bar placement, the nurse should instruct the parents to avoid placing the child in a side-lying position. This position should be avoided to prevent displacement of the steel bar, which could compromise the surgical outcome. Semi-Fowler, supine, and high Fowler positions do not pose the same risk of displacing the steel bar and are generally safe and comfortable for the child in this postoperative period.

Correct Answer: B

Rationale: In Addison's disease, adrenal insufficiency leads to decreased aldosterone production. The decreased aldosterone results in impaired sodium reabsorption and potassium excretion, leading to hyperkalemia. Hypernatremia (Choice A) is unlikely because sodium reabsorption is impaired. Hyperglycemia (Choice C) is not a typical lab finding in Addison's disease. Hypercalcemia (Choice D) is not associated with Addison's disease; rather, it can be seen in conditions like hyperparathyroidism.
