HESI Pediatric Practice Exam Questions
Question 1 of 5
A child who is admitted to the hospital with anemia is anxious, fearful, and hyperventilating. The nurse anticipates the child developing which acid-base imbalance?
Correct Answer: C
Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis.
Question 2 of 5
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?
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.
Question 3 of 5
The nurse is assessing a 4-year-old child who is brought to the clinic for a routine checkup. The child's parent reports that the child has been more irritable and less active over the past week. The nurse notes a petechial rash on the child's trunk and extremities. What should the nurse do first?
Correct Answer: D
Rationale: Petechial rash can be a sign of a serious condition like meningitis, and the healthcare provider should be notified immediately.
Question 4 of 5
A mother brings her 3-week-old infant to the clinic because the baby vomits after eating and always seems hungry. Further assessment indicates that the infant's vomiting is projectile, and the child seems listless. Which additional assessment finding indicates the possibility of a life-threatening complication?
Correct Answer: D
Rationale: In this scenario, the infant presenting with vomiting, lethargy, and projectile vomiting indicates a potential serious condition. Crying without tears is a sign of dehydration, a critical condition that can lead to life-threatening complications in infants. Dehydration can rapidly worsen an infant's condition, making prompt intervention crucial to prevent further complications.
Question 5 of 5
A 7-year-old child with a history of asthma presents to the clinic with shortness of breath and wheezing. The nurse notes that the child's peak flow reading is in the red zone. What should the nurse do first?
Correct Answer: A
Rationale: When a child with asthma presents with shortness of breath and wheezing, and the peak flow reading is in the red zone, indicating severe airflow limitation, the priority intervention is to administer a bronchodilator. Bronchodilators help dilate the airways quickly, improving airflow and assisting with breathing. Reassessing the peak flow reading, notifying the healthcare provider, and providing oxygen therapy may be necessary actions but administering a bronchodilator takes precedence in managing acute asthma exacerbation.
