Pediatric HESI Practice Questions

Correct Answer: C

Rationale: Infants receive passive immunity through antibodies from the mother during pregnancy and breastfeeding, which protect them initially.

Correct Answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is a nonspecific test for inflammation and not specific to atopic dermatitis. Choice B, potassium hydroxide prep, is used to diagnose fungal infections like tinea versicolor, not atopic dermatitis. Choice C, wound culture, is not typically indicated for the diagnosis of atopic dermatitis as it is a chronic inflammatory skin condition rather than an infectious process.

Correct Answer: C

Rationale: During the stage of protest, children may exhibit distress and cling to familiar figures, resisting interactions with others. The most appropriate nursing intervention is to sit by the crib, offer comfort, and wait until the child's anxiety decreases before proceeding with bathing. This approach allows the child to feel supported and gradually transition to accepting care. Choice A is incorrect because forcing comfort may escalate the child's distress. Choice B is inappropriate as it disregards the child's emotional state and rushes into the bathing procedure. Choice D is not ideal as it suggests delaying care for an extended period, which may not address the child's immediate needs for comfort and hygiene.

Correct Answer: A

Rationale: A webbed neck is a classic physical characteristic seen in individuals with Turner syndrome, a genetic condition that results from a missing or partially missing X chromosome in females. This distinctive feature occurs due to excess skin on the neck and is a key clinical clue for healthcare providers. Microcephaly (choice B) refers to a small head size and is not typically associated with Turner syndrome. Gynecomastia (choice C) is the enlargement of breast tissue in males and is not a common finding in Turner syndrome. Cognitive delay (choice D) involves intellectual or developmental delays and is not a specific feature of Turner syndrome.

Correct Answer: C

Rationale: Circumoral cyanosis should alert the nurse to perform further assessment in a 2-month-old infant with Down syndrome. This finding may indicate cardiac or respiratory issues, such as inadequate oxygenation. Small, low-set ears and a protruding furrowed tongue are common physical characteristics associated with Down syndrome and may not necessarily warrant immediate further assessment. A flat occiput is a normal variation in infant anatomy and is not typically a cause for immediate concern in this context.
