Pediatric Practice Exam HESI

Correct Answer: B

Rationale: Choanal atresia is a congenital condition characterized by the blockage of the nasal passages, specifically the choanae that connect the nasal cavity to the nasopharynx. The nurse should assess the nasopharynx to identify any obstruction, confirm the diagnosis, and assess the severity of the condition. Choices A, C, and D are incorrect as they do not pertain to choanal atresia. Choanal atresia specifically involves the nasal passages and nasopharynx, not the rectum, intestinal tract, or laryngopharynx.

Correct Answer: A

Rationale: When a child with diabetes insipidus is treated with vasopressin, the nurse should closely monitor for signs and symptoms of Syndrome of Inappropriate Antidiuretic Hormone (SIADH). Vasopressin, also known as antidiuretic hormone, helps retain water in the body. Excessive vasopressin administration can lead to water retention, dilutional hyponatremia, and potentially result in SIADH. Choices B, C, and D are incorrect because they are not directly associated with the use of vasopressin in treating diabetes insipidus.

Correct Answer: C

Rationale: A caring relationship with family members is an external protective factor that promotes resilience in individuals, especially in adolescents. This support system provides a sense of security, stability, and emotional connection, which can help the teenager navigate challenges and setbacks. Choices A, B, and D allude to internal factors related to personal decision-making, self-awareness, and goal management, which are important but do not directly represent external protective factors involving external relationships or resources.

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: B

Rationale: Using a doll to demonstrate the procedure is the most appropriate preoperative teaching method for a 2-year-old child. It helps them understand what to expect in a non-threatening way by providing a visual representation of the upcoming surgery. Explaining the procedure in simple terms may be too abstract for a child of this age, as they may not fully comprehend verbal explanations. Showing pictures of the hospital environment may not be as effective as using a doll, as it may not provide a concrete understanding of the actual procedure. Allowing the child to play with medical equipment is unsafe and does not adequately prepare them for the surgery, as it may lead to misunderstandings or fear regarding the equipment's actual use during the surgery.
