HESI Pediatric Practice Exam
1. A child with sickle cell anemia is being treated for a vaso-occlusive crisis. Which intervention should the practical nurse (PN) implement?
- A. Apply cold packs to painful areas.
- B. Encourage increased fluid intake.
- C. Administer high doses of vitamin C.
- D. Provide low-calorie meals.
Correct answer: B
Rationale: Encouraging increased fluid intake is crucial in managing vaso-occlusive crises in patients with sickle cell anemia. Dehydration can worsen these crises, so adequate hydration is essential to prevent complications and improve outcomes. Applying cold packs to painful areas may exacerbate vaso-occlusive crises by causing vasoconstriction. Administering high doses of vitamin C is not directly indicated for vaso-occlusive crises in sickle cell anemia. Providing low-calorie meals is not the priority during a vaso-occlusive crisis; maintaining adequate nutrition is important, but hydration takes precedence in this situation.
2. The healthcare provider is assessing an infant with pyloric stenosis. Which pathophysiological mechanism is the most likely consequence of this infant's clinical picture?
- A. Metabolic alkalosis.
- B. Respiratory acidosis.
- C. Metabolic acidosis.
- D. Respiratory alkalosis.
Correct answer: A
Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.
3. The caregiver is providing discharge instructions to the parents of a 6-month-old infant who was hospitalized for bronchiolitis. Which statement by the parents indicates a correct understanding of the instructions?
- A. We should keep our baby away from people with colds
- B. We should continue giving the prescribed medication even if our baby seems better
- C. We should avoid giving solid foods to help with recovery
- D. We can place our baby to sleep on their back to help with breathing
Correct answer: A
Rationale: Keeping the infant away from people with colds is crucial to prevent the spread of respiratory infections, especially for infants recently hospitalized with bronchiolitis. This precaution helps protect the baby from further illnesses and promotes recovery. The other choices are incorrect because it is important to complete the prescribed medication course even if the baby seems better to ensure the infection is fully treated (Choice B). Solid foods are usually introduced around six months of age, so avoiding them entirely may not be necessary (Choice C). Placing the baby to sleep on their back is a safe sleep practice to prevent sudden infant death syndrome (SIDS) but may not directly help with breathing in the context of bronchiolitis (Choice D).
4. The nurse is caring for a 14-year-old adolescent who was admitted to the hospital after a suicide attempt. The adolescent’s mood appears stable, and the healthcare provider has recommended discharge. What is the nurse’s priority action?
- A. Ensure that a safety plan is in place before discharge
- B. Provide education about medication adherence
- C. Encourage the adolescent to participate in group therapy
- D. Schedule a follow-up appointment with a mental health professional
Correct answer: A
Rationale: The priority action for the nurse is to ensure that a safety plan is in place before discharge. A safety plan is essential to assist the adolescent in managing future crises and decreasing the likelihood of another suicide attempt. It provides guidance on coping strategies and resources to help the adolescent stay safe in times of distress.
5. The parents of a 3-year-old boy who has Duchenne muscular dystrophy ask, 'How can our son have this disease? We are wondering if we should have any more children.' What information should the nurse provide to parents?
- 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: The correct answer is A. Duchenne muscular dystrophy is an X-linked recessive disorder that primarily affects males. It is crucial for the nurse to explain to the parents that this condition follows an inheritance pattern where the gene mutation responsible for the disorder is located on the X chromosome. Males have only one X chromosome, so if they inherit the mutated gene, they will develop the disease. Females, on the other hand, have two X chromosomes, providing a backup copy that can compensate for the mutation. Understanding this inheritance pattern is essential for family planning decisions, as the risk of passing on the disorder to future children can be explained based on this genetic inheritance. Choices B, C, and D are incorrect because they do not address the genetic basis of Duchenne muscular dystrophy or its inheritance pattern, which is crucial information for the parents in this scenario.
