Pediatric HESI 2023 Questions
Question 1 of 9
Why is the infant scheduled to receive the intramuscular polio vaccine instead of the oral vaccine, as asked by the parents?
Correct Answer: A
Rationale: The American Academy of Pediatrics recommends the intramuscular polio vaccine over the oral vaccine due to its superior safety profile. Intramuscular administration ensures better immunogenicity and protection against poliovirus. Choice B is incorrect as the intramuscular vaccine is preferred for safety reasons. Choice C is incorrect because the recommendation is based on safety, not cost. Choice D is incorrect as the CDC recommendation is not solely based on immunocompromised status but rather on the overall safety and efficacy of the vaccine.
Question 2 of 9
A 6-year-old child comes to the school nurse reporting a sore throat, and the nurse verifies that the child has a fever and a red, inflamed throat. When a parent of the child arrives at school to take the child home, the nurse urges the parent to seek treatment. The nurse is aware that the causative agent may be beta-hemolytic streptococcus, and the illness may progress to inflamed joints and an infection in the heart. What illness is of most concern to the nurse?
Correct Answer: D
Rationale: The correct answer is D, Rheumatic fever. Rheumatic fever can develop as a complication of untreated strep throat caused by beta-hemolytic streptococcus. It is characterized by inflamed joints and can lead to serious complications such as heart infections. Tetanus (choice A) is caused by a bacterial toxin affecting the nervous system, Influenza (choice B) is a viral respiratory illness, and Scarlet fever (choice C) is also caused by streptococcus but is characterized by a sandpaper-like rash and strawberry tongue. However, in the scenario described, the nurse is most concerned about the child developing rheumatic fever due to the potential serious consequences associated with it.
Question 3 of 9
When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:
Correct Answer: A
Rationale: The correct answer is A: nondisjunction. Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division leading to an extra copy of chromosome 21. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. Choices B, C, and D are incorrect. X-linked recessive inheritance refers to genetic disorders carried on the X chromosome, genomic imprinting involves gene expression based on parental origin, and autosomal dominant inheritance relates to disorders caused by a dominant gene on one of the non-sex chromosomes. In the case of trisomy 21, the cause is specifically related to the error in chromosome division, making nondisjunction the most appropriate answer.
Question 4 of 9
What foods are appropriate for a 30-month-old toddler on a regular diet?
Correct Answer: D
Rationale: Macaroni and cheese and Cheerios are appropriate choices for a 30-month-old toddler on a regular diet as they provide a balance of carbohydrates and protein. Option A, hamburger with bun and grapes, may be difficult for a toddler to chew, and grapes pose a choking hazard. Option B, chicken fingers and french fries, are high in unhealthy fats and sodium. Option C, hot dog with bun and potato chips, are processed foods high in salt and unhealthy fats, not ideal for a toddler's diet.
Question 5 of 9
A healthcare provider is assessing a 3-month-old infant with suspected pyloric stenosis. What clinical manifestation is the healthcare provider likely to observe?
Correct Answer: A
Rationale: Projectile vomiting is a classic clinical manifestation of pyloric stenosis in infants. This occurs due to the narrowing of the pyloric sphincter, leading to the forceful expulsion of gastric contents in a projectile manner. Diarrhea (choice B) is not typically associated with pyloric stenosis. Constipation (choice C) is also not a common symptom of this condition. Abdominal distension (choice D) may occur in pyloric stenosis but is not as specific or characteristic as projectile vomiting in diagnosing this condition.
Question 6 of 9
A parent brings an 18-month-old toddler to the clinic. The parent states, 'My child is so difficult to please, has temper tantrums, and annoys me by throwing food from the table.' What is the nurse's best response?
Correct Answer: B
Rationale: The correct answer is B: 'Toddlers are learning to assert independence, and this behavior is expected at this age.' At 18 months old, toddlers are in the stage of developing autonomy and testing boundaries. It is normal for them to exhibit behaviors such as temper tantrums and defiance as they explore their independence. Choice A is incorrect as discipline at this age is more about setting limits and providing guidance rather than preventing antisocial behaviors. Choice C is inappropriate as leaving a toddler alone in a crib after explaining unacceptable behavior is not a recommended approach for managing toddler behavior. Choice D is incorrect as the described behavior is typical of toddlers asserting independence, not related to the initiative stage of development. The best response involves acknowledging the child's developmental stage and understanding that these behaviors are part of their normal growth and development.
Question 7 of 9
A nurse is planning an initial home care visit to a mother who gave birth to a high-risk infant. For what time of day should the nurse schedule the visit for it to be most productive?
Correct Answer: C
Rationale: Scheduling the visit at a time that is convenient for the family is the most appropriate choice. This ensures that the family is receptive and available, making the visit more productive. Choice A is incorrect because the presence of the husband may be important for support and decision-making. Choice B focuses solely on the mother and the infant's feeding time, which may not align with the family's overall availability. Choice D is incorrect as it emphasizes the nurse's convenience rather than the family's, which may not lead to an effective visit.
Question 8 of 9
A nurse plans to talk to the parents of a toddler about toilet training. What should the nurse explain is the most important factor in the process of toilet training?
Correct Answer: D
Rationale: The most crucial factor in successful toilet training is the parents' commitment to consistently work with their child. While parents' attitude and willingness are important, the key is their dedication to the process. The child's motivation and ability are also significant but rely heavily on parental guidance and support. Therefore, the correct choice is the parents' commitment to work on toilet training.
Question 9 of 9
During a physical examination of a 9-month-old baby, the nurse observes a flat, discolored area on the skin. The nurse documents this as a:
Correct Answer: B
Rationale: The correct answer is B: Macule. A macule is a flat, discolored area on the skin that is smaller than 1 cm in diameter. This term is used to describe conditions like freckles or petechiae. Choice A, Papule, refers to a small, solid, raised skin lesion (<0.5 cm) like a pimple. Choice C, Vesicle, describes a small blister filled with clear fluid. Choice D, Scale, refers to flakes or plates of dead skin that may be dry or greasy.
