Pediatric HESI Practice Questions

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: 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: B

Rationale: The correct answer is B: Signs of dehydration. Infants with hypertrophic pyloric stenosis (HPS) are at high risk of dehydration due to frequent vomiting. Assessing for signs of dehydration, such as decreased urine output, dry mucous membranes, and sunken fontanelles, is crucial for early intervention and management. Choices A, C, and D are not the most critical assessments for HPS. The quality of the cry (choice A) may not provide as much relevant information in this case. Coughing up of feedings (choice C) may be a symptom but is not as crucial as assessing for dehydration. Characteristics of the stool (choice D) are important but assessing for signs of dehydration takes precedence due to the immediate risk it poses to the infant's health.

Correct Answer: B

Rationale: Administering factor VIII in the morning on scheduled days is the correct choice. This timing ensures that the factor VIII levels remain stable throughout the day when the child is active and at risk of bleeding. Choice A is incorrect because factor VIII should be given on a regular schedule rather than only when a bleed is suspected. Choice C is not ideal as the child may be more active during the day, increasing the risk of bleeding. Choice D is also incorrect as the administration should follow a specific schedule to maintain therapeutic levels of factor VIII in the child's system.

Correct Answer: A

Rationale: Administering bronchodilators is a crucial nursing intervention for a child with asthma as it helps to open the airways and improve breathing. Bronchodilators work by relaxing the muscles around the airways, making breathing easier for the child. Encouraging physical activity may exacerbate asthma symptoms in some cases, so it is not recommended as a primary intervention. Monitoring oxygen saturation is important in assessing respiratory status, but administering bronchodilators would take precedence in this situation. Providing nutritional support is a general nursing intervention and not specific to managing asthma symptoms.
