HESI Pediatrics Quizlet Questions
Question 1 of 5
How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?
Correct Answer: B
Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.
Question 2 of 5
The school nurse is presenting a class to a group of students about common overuse disorders. Which disorder would the school nurse include?
Correct Answer: C
Rationale: The correct answer is C: Osgood-Schlatter disease. This condition is a common overuse injury that affects the knee. Osgood-Schlatter disease typically occurs in children and adolescents who are involved in activities that require frequent running, jumping, and kicking. It is characterized by pain, swelling, and tenderness at the tibial tuberosity, where the patellar tendon inserts into the tibia. Choice A, Dislocated radial head, is not an overuse disorder but rather a form of elbow injury where the head of the radius bone is displaced from its normal position. Choice B, Transient synovitis of the hip, is a self-limiting condition that causes hip pain and limping in children. It is not typically considered an overuse disorder. Choice D, Scoliosis, is a condition characterized by an abnormal lateral curvature of the spine. While it may be related to certain activities or postures, it is not primarily classified as an overuse disorder.
Question 3 of 5
A child is brought to the clinic after tripping over a rock. The child states, 'I twisted my ankle,' and is given a diagnosis of a sprain. What intervention is most important for the nurse to include in the discharge instructions for this child?
Correct Answer: A
Rationale: The correct intervention for a sprained ankle is to apply ice for 20 minutes every hour for the first 24 hours, then remove for 60 minutes to prevent tissue damage. This regimen helps reduce swelling and pain. Bed rest with the leg elevated for an extended period (36 hours) may lead to stiffness and decreased range of motion. While NSAIDs can be used for pain, they may not be necessary if pain is manageable with ice and rest. Using a compression dressing for 72 hours continuously may impede proper circulation and delay healing by restricting blood flow.
Question 4 of 5
When administering IV fluids to a dehydrated infant, what intervention is most important at this time?
Correct Answer: B
Rationale: Monitoring the intravenous drop rate is the most crucial intervention when administering IV fluids to a dehydrated infant. This ensures that the correct amount of fluids is being delivered to the infant at the appropriate rate. While continuing the prescribed flow rate (Choice A) may be important, it does not allow for real-time adjustments that may be necessary during the infusion. Calculating the total necessary intake (Choice C) should have been determined before initiating IV therapy. Maintaining the fluid at body temperature (Choice D) is important for patient comfort but is not as critical as ensuring the proper administration of fluids.
Question 5 of 5
A child with a cardiac malformation associated with left-to-right shunting. What does this type of congenital disorder lead to primarily?
Correct Answer: D
Rationale: Left-to-right shunting in a cardiac malformation results in increased blood flow to the lungs. This increased blood flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a characteristic directly associated with left-to-right shunting. Severe growth retardation (Choice B) is not a typical manifestation of this type of congenital disorder. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions like chronic respiratory or cardiac diseases, not specifically with left-to-right shunting and associated cardiac malformations.
