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: B

Rationale: The priority nursing intervention for a child hospitalized for acute lymphoblastic leukemia (ALL) is preventing infection. Children with ALL have compromised immune systems, making them highly vulnerable to infections. Preventing infections through strict aseptic techniques, isolation precautions, and proper hygiene is crucial to safeguard the child's health. Administering antibiotics (choice A) may be necessary if an infection occurs, but the primary focus should be on infection prevention. While providing nutritional support (choice C) is important, preventing infection takes precedence due to its direct impact on the child's survival. Managing pain (choice D) is essential for the child's comfort but is not the priority over preventing life-threatening infections in this scenario.

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.

Correct Answer: B

Rationale: Breastfeeding is recommended to help prevent constipation in infants due to the easily digestible nature of breast milk, which often leads to softer stools. Breastfeeding is preferred over formula feeding as it provides optimal nutrition for the infant's digestive system. Choice A, using a soy formula if necessary, may be considered only if there are specific dietary concerns or allergies; however, breast milk is still the preferred option. Choice C, avoiding administering a suppository nightly, is correct as it is not a routine method for preventing constipation in infants and may not be appropriate without medical advice. Choice D, not offering glucose water between feedings, is recommended as it may not address the root cause of constipation and may introduce unnecessary sugar to the infant's diet.

Correct Answer: B

Rationale: A cross-cut nipple is the most appropriate choice for feeding an infant with a unilateral cleft lip and palate. Using a cross-cut nipple helps regulate the flow of milk, making feeding easier for the infant and reducing the risk of aspiration. Plastic spoons, parenteral infusion, and rubber-tipped syringes are not recommended for feeding infants with cleft lip and palate as they can pose risks such as choking, aspiration, or inadequate milk intake. It is essential to choose a feeding method that minimizes these risks and ensures proper nutrition for the infant.
