Pediatric Practice Exam HESI
1. A parent and 3-month-old infant are visiting the well-baby clinic for a routine examination. What should the nurse include in the accident prevention teaching plan?
- A. Remove small objects from the floor.
- B. Cover electric outlets with safety plugs.
- C. Remove toxic substances from low areas.
- D. Test the temperature of water before bathing.
Correct answer: D
Rationale: Testing the temperature of water before bathing is crucial to prevent burns, which is a significant risk for infants due to their sensitive skin. Infants have delicate skin that can easily be burned by water that is too hot. Testing the water temperature before bathing ensures that the water is at a safe and comfortable level for the infant. While choices A, B, and C are also important in accident prevention, such as reducing choking hazards, preventing electric shocks, and avoiding poisoning, testing the water temperature before bathing is the most immediate and direct action to prevent harm to the infant during bathing.
2. When obtaining a health history from parents of a 4-month-old boy with congenital hypothyroidism, what would the nurse most likely assess?
- A. The child's growth is above normal for his age.
- B. The child is active and playful.
- C. The skin appears pink and healthy.
- D. It is difficult to keep the child awake.
Correct answer: D
Rationale: In congenital hypothyroidism, infants often experience lethargy and difficulty staying awake due to low thyroid hormone levels. Choice A is incorrect as hypothyroidism can lead to poor growth in infants. Choice B is incorrect because hypothyroidism can cause decreased activity levels and lethargy rather than being active and playful. Choice C is incorrect as hypothyroidism can result in dry skin and poor skin tone, not necessarily pink and healthy-looking skin.
3. The nurse is caring for an infant with osteogenesis imperfecta and is providing instruction on how to reduce the risk of injury. Which response from the mother indicates a need for further teaching?
- A. I need to avoid pushing or pulling on an arm or leg.
- B. I must avoid lifting the baby from under the armpits.
- C. I should not bend an arm or leg into an awkward position.
- D. We must avoid lifting the legs by the ankles to change diapers.
Correct answer: B
Rationale: Lifting the baby from under the armpits can cause fractures in infants with osteogenesis imperfecta. The correct approach is to support the baby's body and head carefully, avoiding pressure on vulnerable areas prone to fractures. Choices A, C, and D demonstrate proper awareness of caring for an infant with osteogenesis imperfecta by emphasizing caution to prevent fractures.
4. A health care provider orders a tap water enema for a 6-month-old infant with suspected Hirschsprung disease. What rationale causes the nurse to question the order?
- A. The result could lead to loss of necessary nutrients.
- B. It could cause a fluid and electrolyte imbalance.
- C. It could increase the fear of intrusive procedures.
- D. The result could cause shock from a sudden drop in temperature.
Correct answer: B
Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas do not directly lead to loss of necessary nutrients. Choice C is incorrect as it focuses on emotional impact rather than physiological risks. Choice D is incorrect as shock from a sudden drop in temperature is not a common consequence of a tap water enema in this scenario.
5. A newborn is admitted to the neonatal intensive care unit (NICU) with choanal atresia. Which part of the infant’s body should the nurse assess?
- A. Rectum
- B. Nasopharynx
- C. Intestinal tract
- D. Laryngopharynx
Correct answer: B
Rationale: Choanal atresia is a congenital condition that presents with a blockage in the nasal passages at the junction of the nasal cavity and the nasopharynx. To assess and confirm the diagnosis of choanal atresia, the nurse should focus on assessing the nasopharynx. Choices A, C, and D are incorrect as choanal atresia specifically involves a blockage in the nasal passages, not the rectum, intestinal tract, or laryngopharynx. By assessing the nasopharynx, the severity of the obstruction can be determined, aiding in planning appropriate interventions for the newborn.
