HESI Pediatrics Practice Exam
1. The caregiver is teaching a group of parents about injury prevention for toddlers. Which statement by a parent indicates a need for further teaching?
- A. I will keep all cleaning supplies locked away.
- B. I will teach my child how to swim this summer.
- C. I will make sure my child wears a helmet while riding a tricycle.
- D. I will place my child in a car seat for every car ride.
Correct answer: B
Rationale: Teaching children how to swim is valuable, but parental supervision around water is essential to prevent drowning. It's crucial to emphasize constant supervision when young children are near water, regardless of their swimming abilities. The other choices (A, C, and D) demonstrate appropriate safety measures for injury prevention in toddlers, such as securing cleaning supplies, ensuring helmet use during tricycle rides, and using a car seat for every car ride.
2. What information should the nurse provide to parents of a 3-year-old boy with Duchenne muscular dystrophy who inquire about the disease and future children?
- A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family
- B. The striated muscle groups of males can be impacted by a lack of the protein dystrophin in their mothers
- C. The male infant had a viral infection that went unnoticed and untreated so muscle damage was incurred
- D. Birth trauma with a breech vaginal birth causes damage to the spinal cord, thus weakening the muscles
Correct answer: A
Rationale: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons. Choice B is incorrect as it inaccurately implies that the lack of dystrophin in mothers impacts their sons' muscle groups. Choice C is incorrect as it suggests a viral infection caused the muscle damage, which is not the case with Duchenne muscular dystrophy. Choice D is incorrect as it attributes the muscle weakness to birth trauma instead of the genetic nature of the disorder.
3. The nurse is caring for a 3-year-old child who has been recently diagnosed with cystic fibrosis. Which discharge instruction by the nurse is most important to promote pulmonary function?
- A. Chest physiotherapy should be performed before meals and at bedtime
- B. Cough suppressants can be used up to four times a day for relief
- C. Oxygen should be given through a nasal cannula between 4-6 L/min
- D. Exercise is discouraged in order to preserve pulmonary vital capacity
Correct answer: B
Rationale: In cystic fibrosis, thick mucus obstructs the airways, making it difficult to clear from the lungs. Cough suppressants can help reduce the discomfort associated with persistent coughing, allowing the child to cough more effectively to clear the mucus, thus promoting pulmonary function. Chest physiotherapy, not exercise, helps mobilize the mucus. Oxygen therapy may be needed but is not the most important for promoting pulmonary function in this case.
4. The parents of a 15-month-old boy tell the nurse that they are concerned because their son brings his spoon to his mouth but does not turn it over. What action should the nurse implement first?
- A. Discuss the possibility of a referral to a specialist
- B. Question the parents about their concern
- C. Advise the parents on proper spoon handling techniques for the child
- D. Recommend extending mealtimes to allow the child to finish eating
Correct answer: B
Rationale: The initial action for the nurse is to question the parents about their concerns. By doing so, the nurse can gather more information to understand the situation better. This helps in determining if the child's behavior is within normal development or if further action or referrals are necessary. Choice A is incorrect as it jumps to a specialist referral without fully assessing the situation first. Choice C is also incorrect because assuming the parents need advice on proper spoon handling techniques may not be the case. Choice D is incorrect as it does not address the core concern raised by the parents.
5. The healthcare provider is preparing to administer a scheduled dose of digoxin to a 4-year-old child with heart failure. The healthcare provider notes that the child’s heart rate is 70 beats per minute. What should the healthcare provider do next?
- A. Administer the medication as prescribed
- B. Hold the medication and notify the healthcare provider
- C. Recheck the heart rate in 30 minutes
- D. Administer half of the prescribed dose
Correct answer: B
Rationale: In pediatric patients, digoxin administration is guided by the heart rate. If the child's heart rate is below the established threshold, which is typically 90-100 beats per minute in a 4-year-old, the medication should be withheld, and the healthcare provider should be notified for further evaluation and instructions. Choice A is incorrect because administering the medication when the heart rate is low can lead to adverse effects. Rechecking the heart rate in 30 minutes (Choice C) may delay necessary intervention if the heart rate remains low. Administering half of the prescribed dose (Choice D) is not recommended without healthcare provider guidance.
