Pediatric Practice Exam HESI

Correct Answer: B

Rationale: Breastfeeding is the best recommendation to help prevent constipation in infants. Breast milk is easily digestible and contains the right balance of nutrients, which can lead to softer stools, thus reducing the likelihood of constipation. Offering a soy formula (Choice A) may not necessarily prevent constipation as effectively as breast milk due to differences in nutrient composition. Administering a suppository nightly (Choice C) is not a routine measure for preventing constipation in infants and may not be suitable for regular use in this scenario. Offering glucose water (Choice D) between feedings is not recommended as it does not provide the necessary nutrients found in breast milk, which are essential for preventing constipation and promoting overall health in newborns.

Correct Answer: C

Rationale: Preventing straining at stool is crucial postoperatively after heart surgery for tetralogy of Fallot to avoid increasing intrathoracic pressure and placing stress on the surgical site. This can help prevent complications and promote faster healing. While crying, coughing, and unnecessary movement are common postoperative behaviors, they are not specifically linked to worsening outcomes in this context. Straining at stool is particularly emphasized due to its potential to impact the surgical site and overall recovery process.

Correct Answer: C

Rationale: The correct answer is C. Using echolalia, which is the repetition of words or phrases, is not typical for a 2-year-old child and may indicate the need for further evaluation. Choices A, B, and D are all within the expected developmental skills for a 2-year-old. While most 2-year-olds may not be able to stand on one foot, it is not a cause for concern at this age. Building a tower of 7 blocks and coloring outside the lines of a picture are both appropriate for a 2-year-old's developmental skills.

Correct Answer: A

Rationale: Nausea and vomiting are more common in children following head trauma due to their higher risk of increased intracranial pressure. Children have less skull compliance and higher brain water content, making them more susceptible to developing symptoms like nausea and vomiting. Altered mental status (choice B) can occur in both children and adults but is not more common in children. Tachycardia and diaphoresis (choice C) are nonspecific and can occur in both age groups. Changes in pupillary reaction (choice D) are not typically more common in children following head trauma compared to adults.

Correct Answer: D

Rationale: Full-thickness burns are characterized by a leathery, dry appearance with numbness due to nerve damage. Choice A describes characteristics of superficial burns, which are not full-thickness. Choice B describes characteristics of partial-thickness burns with intact blisters, not full-thickness burns. Choice C describes characteristics of partial-thickness burns with blistering and swelling, not full-thickness burns.
