Pediatric Practice Exam HESI
1. A child has been admitted to the pediatric unit with a severe asthma attack. What type of acid-base imbalance should the nurse expect the child to develop?
- A. metabolic alkalosis due to insufficient production of acid metabolites
- B. respiratory alkalosis due to depressed respirations and retention of carbon dioxide
- C. respiratory acidosis due to impaired respirations and increased formation of carbonic acid
- D. metabolic acidosis due to the kidneys' inability to compensate for decreased carbonic acid formation
Correct answer: C
Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis. This occurs due to impaired respirations, leading to the retention of carbon dioxide and the formation of carbonic acid. Choice A is incorrect as metabolic alkalosis is not expected in this situation. Choice B is incorrect as respiratory alkalosis does not align with the scenario of impaired respirations in severe asthma attacks. Choice D is also incorrect as it describes metabolic acidosis, which is not typically associated with severe asthma attacks.
2. A child with a diagnosis of nephrotic syndrome is being discharged. What dietary instructions should the nurse provide?
- A. Encourage a high-protein diet
- B. Avoid foods high in salt
- C. Encourage a low-sodium diet
- D. Encourage a low-protein diet
Correct answer: B
Rationale: For a child with nephrotic syndrome, it is important to avoid foods high in salt. This instruction helps manage symptoms and prevent complications associated with the condition. High salt intake can lead to fluid retention and worsen edema, which are common issues in nephrotic syndrome. Encouraging a low-sodium diet is crucial to maintaining fluid balance and reducing strain on the kidneys. Choices A, C, and D are incorrect because a high-protein diet can further stress the kidneys, while a low-protein diet may not be necessary unless specifically advised by the healthcare provider. Encouraging a low-sodium diet is more appropriate for managing nephrotic syndrome.
3. A nurse is teaching the parents of a toddler about the signs and symptoms of lead poisoning. Which symptom should the nurse emphasize?
- A. Abdominal pain
- B. Constipation
- C. Irritability
- D. Frequent urination
Correct answer: C
Rationale: Irritability is a significant symptom of lead poisoning in toddlers and should be emphasized to parents. Lead poisoning can manifest with various symptoms, but irritability is particularly common in children exposed to lead. Abdominal pain (Choice A) is not a typical symptom of lead poisoning in toddlers. While constipation (Choice B) can occur, it is less specific and less common than irritability. Frequent urination (Choice D) is not a typical symptom associated with lead poisoning in toddlers and is less relevant for parents to recognize in this context.
4. The nurse is assessing a child with a possible fracture. What would the nurse identify as the most reliable indicator?
- A. Lack of spontaneous movement
- B. Point tenderness
- C. Bruising
- D. Inability to bear weight
Correct answer: B
Rationale: Point tenderness is the most reliable indicator of a possible fracture in a child. It is a localized tenderness experienced when pressure is applied to a specific area, suggesting a potential fracture. This tenderness is considered more specific to a fracture than other symptoms such as lack of spontaneous movement, bruising, or inability to bear weight. Lack of spontaneous movement and inability to bear weight can be present in various musculoskeletal injuries, while bruising may not always be immediate or specific to a fracture.
5. When developing the plan of care for a child with burns requiring fluid replacement therapy, what information would the nurse expect to include?
- A. Administration of colloid initially followed by a crystalloid
- B. Determination of fluid replacement based on the type of burn
- C. Administration of most of the volume during the first 8 hours
- D. Monitoring of hourly urine output to achieve less than 1 mL/kg/hr
Correct answer: C
Rationale: The correct answer is C. In fluid replacement therapy for burns, it is crucial to administer most of the volume during the first 8 hours to prevent shock and maintain perfusion. This rapid administration is essential to stabilize the child's condition. Choices A and B are incorrect because the initial fluid replacement in burns typically involves administering crystalloids, not colloids, and the fluid replacement is generally calculated based on the extent of the burn injury, not the type of burn. Choice D is incorrect as monitoring hourly urine output to achieve less than 1 mL/kg/hr is not recommended in burn patients; instead, urine output should be monitored to achieve 1-2 mL/kg/hr in children to ensure adequate renal perfusion.
