Pediatric HESI 2024 Questions
Question 1 of 5
What are the most common signs and symptoms of leukemia related to bone marrow involvement?
Correct Answer: A
Rationale: Petechiae, infection, and fatigue are common signs and symptoms of leukemia related to bone marrow involvement. Petechiae are small red or purple spots on the skin caused by bleeding under the skin due to low platelet counts. Infection susceptibility increases due to decreased white blood cells from compromised bone marrow function. Fatigue is a common symptom of anemia resulting from decreased red blood cell production. Choices B, C, and D are incorrect as they do not align with the typical signs and symptoms of leukemia associated with bone marrow dysfunction.
Question 2 of 5
What should be included in the teaching plan for parents of an infant diagnosed with phenylketonuria (PKU)?
Correct Answer: A
Rationale: The correct answer is A: 'Mental retardation occurs if PKU is untreated.' Phenylketonuria (PKU) is a metabolic disorder that results in the inability to metabolize phenylalanine properly. Without proper dietary management, high levels of phenylalanine can lead to severe mental retardation and other neurological problems. Therefore, educating parents about the importance of early and consistent treatment to prevent mental retardation is crucial. Choice B is incorrect because testing for PKU is typically done shortly after birth, not immediately. Choice C is incorrect because treatment for PKU primarily involves strict dietary management to control phenylalanine intake, not lifelong medications. Choice D is incorrect because PKU is inherited in an autosomal recessive pattern, not as an autosomal dominant gene.
Question 3 of 5
Why should the nurse closely monitor the IV flow rate for a 5-month-old infant with severe diarrhea receiving IV fluids?
Correct Answer: D
Rationale: The correct answer is D: Preventing cardiac overload. Infants are highly vulnerable to fluid overload, making it essential to carefully monitor IV flow rates to prevent complications such as cardiac overload. Rapid administration of IV fluids can lead to an excessive increase in circulating volume, potentially causing cardiac strain or heart failure in infants. Choices A, B, and C are incorrect. Monitoring the IV flow rate is not primarily aimed at limiting output, replacing lost fluids, or avoiding IV infiltration in this scenario. The key concern is to prevent the risk of cardiac overload due to the infant's susceptibility to fluid imbalances.
Question 4 of 5
What information would the nurse include in the preoperative plan of care for an infant with myelomeningocele?
Correct Answer: B
Rationale: The correct answer is B: Covering the sac with saline-soaked nonadhesive gauze. This intervention is essential in caring for an infant with myelomeningocele as it helps prevent infection and maintains a moist environment around the sac before surgical repair. Positioning the infant supine with a pillow under the buttocks (Choice A) may be suitable for comfort but is not directly related to managing the myelomeningocele. Wrapping the infant snugly in a blanket (Choice C) and applying a diaper (Choice D) are not recommended as they can increase the risk of infection and damage to the sac.
Question 5 of 5
A newborn is diagnosed with metatarsus adductus. The parents ask the nurse how this occurred. Which response by the nurse would be most appropriate?
Correct Answer: B
Rationale: Metatarsus adductus is a condition where the front part of the foot is turned inward. It is often caused by the baby's position in the womb, leading to pressure on the foot during fetal development. Choice A is incorrect as metatarsus adductus is not primarily caused by a genetic defect in the bones. Choice C is incorrect as the cause of metatarsus adductus is known to be related to intrauterine positioning. Choice D is incorrect as metatarsus adductus specifically pertains to the foot and not the hip.
