HESI Pediatric Practice Exam
1. A child with a fever of 39°C (102.2°F) and a sore throat is brought to the clinic. The practical nurse suspects the child has streptococcal pharyngitis. Which diagnostic test should the practical nurse prepare the child for?
- A. Rapid antigen detection test.
- B. Throat culture.
- C. Complete blood count (CBC).
- D. Chest X-ray.
Correct answer: A
Rationale: A rapid antigen detection test is the appropriate diagnostic test for suspected streptococcal pharyngitis. This test is commonly used due to its quick results, helping in the prompt diagnosis and appropriate treatment of the condition. It specifically detects the presence of streptococcal antigens in the throat, aiding in confirming the diagnosis and guiding the healthcare provider in determining the most suitable treatment plan. Throat culture (Choice B) is a confirmatory test but is not as rapid as the rapid antigen detection test. Complete blood count (Choice C) and Chest X-ray (Choice D) are not specific tests for streptococcal pharyngitis and would not aid in confirming the diagnosis.
2. Which nursing intervention is most important to assist in detecting hypopituitarism and hyperpituitarism in children?
- A. Carefully recording the height and weight of children to detect inappropriate growth.
- B. Performing head circumference measurements on infants under one year of age.
- C. Assessing for behavioral problems at home and school by interviewing the parents.
- D. Noting tracked weight gain without a gain in height on a growth chart.
Correct answer: A
Rationale: Recording the height and weight of children is crucial in detecting growth abnormalities like hypopituitarism and hyperpituitarism. Inappropriate growth patterns, such as disproportionate weight gain or stunted height, can be indicative of these conditions. Regular monitoring of height and weight is a fundamental nursing intervention that can aid in the early identification and management of pituitary-related disorders in children.
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. The mother of a 4-month-old asks the nurse for advice in preventing diaper rash. What suggestion should the nurse provide?
- A. At diaper change generously powder the baby's diaper area with talcum powder to promote dryness.
- B. Wash the diaper area every 2 hours with soap and water to help prevent skin breakdown.
- C. Use a barrier cream, such as zinc oxide, which does not have to be completely removed with each diaper change.
- D. Place a cloth diaper inside the disposable diaper for overnight periods when increased wearing time is likely.
Correct answer: C
Rationale: Using a barrier cream like zinc oxide protects the skin and helps prevent diaper rash.
5. The practical nurse is reinforcing information about Lyme disease prevention with a client who is preparing for a camping trip with family. Which statement by the client informs the nurse that the client understands the instruction?
- A. I'll make sure my son wears dark clothing on his hike.
- B. I'll get a prescription for amoxicillin to take with us.
- C. We should all get the Lyme disease vaccine before our trip.
- D. We will wear long pants and long-sleeved shirts in the woods.
Correct answer: D
Rationale: The correct answer is D. Wearing long pants and long-sleeved shirts is an effective preventive measure against tick bites, which reduces the risk of contracting Lyme disease. This attire helps to minimize skin exposure to ticks, thereby decreasing the chances of a tick attaching and transmitting the disease-causing bacteria.
