HESI Pediatric Practice Exam
1. During a well-baby check of a 7-month-old infant, the practical nurse notes an absence of babbling. Which focused assessment should the PN implement?
- A. Visual function.
- B. Auditory function.
- C. Cognitive function.
- D. Social development.
Correct answer: B
Rationale: The absence of babbling in a 7-month-old infant is a concerning auditory development milestone. Babbling is an early stage of language development that involves making various sounds. A lack of babbling could indicate a hearing impairment or other auditory issues. Therefore, the practical nurse should focus on assessing the infant's auditory function to determine if further evaluation or intervention is necessary. Choices A, C, and D are incorrect because the absence of babbling specifically points towards a potential issue related to auditory function rather than visual, cognitive, or social development.
2. A 6-year-old child is diagnosed with rheumatic fever and demonstrates associated chorea (sudden aimless movements of the arms and legs). Which information should the nurse provide to the parents?
- A. Permanent lifestyle changes need to be made to promote safety in the home
- B. The chorea or movements are temporary and will eventually disappear
- C. Muscle tension is decreased with fine motor project skills, so these activities should be encouraged
- D. Consistent discipline is needed to help the child control the movements
Correct answer: C
Rationale: Chorea associated with rheumatic fever is usually temporary and will subside over time.
3. 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.
4. A child with leukemia is admitted for chemotherapy, and the nursing diagnosis 'altered nutrition, less than body requirements related to anorexia, nausea, and vomiting' is identified. Which intervention should the nurse include in this child's plan of care?
- A. Encourage a variety of large portions of food at every meal.
- B. Allow the child to eat any food desired and tolerated.
- C. Recommend eating the food as siblings eat at home.
- D. Restrict food brought from fast food restaurants.
Correct answer: B
Rationale: Allowing the child to eat any food desired and tolerated is the most appropriate intervention for a child with altered nutrition due to anorexia, nausea, and vomiting. It is crucial to prioritize maintaining adequate nutritional intake, and by allowing the child to choose foods they desire and can tolerate, the chances of improving their nutritional status increase. This approach helps in ensuring that the child receives necessary nutrients during chemotherapy, even if their appetite is affected by the treatment. Encouraging a variety of large portions of food at every meal (Choice A) may overwhelm the child and worsen their symptoms. Recommending eating the food as siblings eat at home (Choice C) may not align with the child's preferences and tolerances. Restricting food brought from fast food restaurants (Choice D) is not suitable as it may limit the child's options and preferences during a challenging time.
5. A child who weighs 25 kg is receiving IV ampicillin at a dose of 300 mg/kg/24 hours in equally divided doses every 4 hours. How many milligrams should the nurse administer to the child for each dose?
- A. 1875 mg
- B. 625 mg
- C. 2000 mg
- D. 1500 mg
Correct answer: A
Rationale: To calculate the correct dose for each administration, you first need to find the total daily dose: 300 mg/kg * 25 kg = 7500 mg/day. Since this total dose is divided into equally divided doses every 4 hours, there are 6 doses in 24 hours. Therefore, 7500 mg ÷ 6 doses = 1250 mg per dose. The nurse should administer 1250 mg every 4 hours, resulting in a total of 1875 mg for each dose in a 24-hour period. Choice A, 1875 mg, is the correct answer. Choice B, 625 mg, is incorrect as it does not consider the total daily dose and the frequency of administration. Choice C, 2000 mg, is incorrect as it is not the calculated dosage based on the given parameters. Choice D, 1500 mg, is also incorrect as it does not reflect the correct dosage calculation for each dose.
