HESI Pediatrics Practice Exam

Correct Answer: A

Rationale: Corrected Question: The healthcare provider plans to screen only the highest risk children for scoliosis. Which group of children should the healthcare provider screen first? Girls between ages 10 and 14 are at the highest risk for scoliosis and should be screened first as they have a higher incidence of developing scoliosis during their adolescent growth spurt. Early detection and intervention can help prevent further complications associated with scoliosis. Boys between ages 10 and 14 (choice B) are not at the highest risk compared to girls in the same age group. Boys and girls between 12 and 14 (choice C) are at a lower risk compared to girls between ages 10 and 14. Boys and girls between 8 and 12 (choice D) are at a lower risk group compared to girls between ages 10 and 14.

Correct Answer: D

Rationale: The correct answer is D. Placing the child in a supine position to begin percussion is incorrect for chest physiotherapy (CPT). This position is not effective for CPT as it may lead to improper drainage of secretions. The child should be in an appropriate sitting or slightly reclined position to ensure proper lung drainage during CPT. Choices A, B, and C are all appropriate actions for chest physiotherapy. Performing CPT when the child awakens helps in clearing secretions, using a cupped hand during percussion is a proper technique to promote secretion movement, and administering a bronchodilator before CPT can help open up the airways for better clearance.

Correct Answer: D

Rationale: Providing positive feedback to the mother for correctly administering the iron supplements is essential as it reinforces proper medication administration practices. This encouragement can help build the mother's confidence and ensure that she continues to administer the supplements correctly in the future, promoting the infant's health and well-being. Choices A, B, and C are incorrect because there is no need to suggest altering the administration method, changing the liquid used, or restricting feeding immediately after administering the iron supplement. Giving positive feedback is the most appropriate action in this scenario to acknowledge the mother's correct administration technique.

Correct Answer: A

Rationale: In infants, laughing readily and turning from back to side are developmental milestones that indicate effective thyroid therapy and normal development. These actions demonstrate improved muscle tone, coordination, and overall growth, which are key indicators of successful treatment for hypothyroidism in infants. Choices B, C, and D describe behaviors that are not specific indicators of thyroid therapy effectiveness in treating hypothyroidism in infants.

Correct Answer: A

Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.
