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. When administering IV fluids to a dehydrated infant, what intervention is most important at this time?
- A. Continuing the prescribed flow rate
- B. Monitoring the intravenous drop rate
- C. Calculating the total necessary intake
- D. Maintaining the fluid at body temperature
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.
3. Which of the following findings would indicate altered mental status in a small child?
- A. Recognizing the parents
- B. Showing fright at the EMT-B's presence
- C. Displaying a lack of attention to the EMT-B's presence
- D. Maintaining consistent eye contact with the EMT-B
Correct answer: C
Rationale: In a small child, displaying a lack of attention to the EMT-B's presence would indicate altered mental status. This behavior suggests a diminished level of consciousness or awareness, which is concerning. Recognizing the parents (Choice A) is a normal and expected behavior for a child. Showing fright at the EMT-B's presence (Choice B) may indicate fear or anxiety but not necessarily altered mental status. Maintaining consistent eye contact with the EMT-B (Choice D) may indicate engagement or curiosity rather than altered mental status.
4. What is an essential nursing action when caring for a young child with severe diarrhea?
- A. Maintain the IV.
- B. Take daily weights.
- C. Replace the lost calories.
- D. Promote perianal skin integrity.
Correct answer: D
Rationale: Promoting perianal skin integrity is crucial when caring for a young child with severe diarrhea to prevent skin breakdown from the irritation caused by frequent bowel movements. Maintaining the IV (Choice A) may be important for hydration but is not directly related to managing skin integrity. Taking daily weights (Choice B) is important for monitoring fluid balance but does not address the immediate need to prevent skin breakdown. While replacing lost calories (Choice C) is important, it is not the priority when a child is experiencing severe diarrhea and skin integrity is at risk.
5. A 6-year-old with muscular dystrophy was recently injured falling out of bed at home. What intervention should the nurse suggest to prevent further injury?
- A. Recommend raising the bed's side rails when a caregiver is not present.
- B. Suggest a caregiver be present continuously to prevent falls from bed.
- C. Encourage the use of loose restraints while in bed.
- D. Recommend raising the bed's side rails throughout the day and night.
Correct answer: A
Rationale: In this scenario, the most appropriate intervention to prevent further injury is to raise the bed's side rails when a caregiver is not present. This measure helps in preventing falls without the need for constant supervision. Choice B is not practical as continuous caregiver presence may not always be feasible. Choice C is unsafe as loose restraints can pose a strangulation risk. Choice D does not address the need for intervention when a caregiver is absent, potentially leading to an increased risk of falls.
