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 has undergone surgery using steel bar placement to correct pectus excavatum. What position would the nurse instruct the parents to avoid?
- A. Semi-Fowler
- B. Supine
- C. High Fowler
- D. Side-lying
Correct answer: D
Rationale: The correct answer is D: Side-lying. After surgery using steel bar placement to correct pectus excavatum, the nurse should instruct the parents to avoid placing the child in a side-lying position. This position should be avoided to prevent displacement of the steel bar. Choices A, B, and C are incorrect. Semi-Fowler, Supine, and High Fowler positions are generally safe and commonly used in postoperative care, but in this specific case, side-lying should be avoided to ensure the effectiveness of the surgical correction.
3. Where should the child admitted with injuries that may be related to abuse be placed?
- A. In a private room
- B. With an older, friendly child
- C. With a child of the same age
- D. In a room near the nurses’ desk
Correct answer: D
Rationale: The correct answer is to place the child in a room near the nurses’ desk. This placement allows for close monitoring and immediate intervention if needed, ensuring the safety and well-being of the child. Placing the child in a private room (Choice A) may limit visibility and monitoring. Putting the child with an older, friendly child (Choice B) or a child of the same age (Choice C) does not prioritize the necessary close monitoring and intervention that a child potentially experiencing abuse requires. Hence, placing the child in a room near the nurses’ desk is the most appropriate choice in this scenario.
4. The caregiver explains to the parent of a 2-year-old child that the toddler’s negativism is expected at this age. What need is this behavior meeting?
- A. Trust
- B. Attention
- C. Discipline
- D. Independence
Correct answer: D
Rationale: Negativism in toddlers is a common behavior at this age as they begin to assert their independence and show a desire to control their environment. Choice A, 'Trust,' does not align with the behavior of negativism, as it is more about the child's growing autonomy. Choice B, 'Attention,' while important for child development, is not the primary need being met by negativism in this context. Choice C, 'Discipline,' though important in guiding behavior, is not the underlying need being expressed through negativism. Therefore, the correct answer is D, 'Independence,' as toddlers exhibit negativism as a way to assert their independence and autonomy.
5. When a child with a diagnosis of asthma is prescribed a peak flow meter, what should the nurse teach the child and parents about using this device?
- A. Use the device before taking medication
- B. Use the device during asthma attacks
- C. Record the best of three attempts
- D. Use the device after eating
Correct answer: C
Rationale: The correct answer is to record the best of three attempts when using a peak flow meter. This method provides a more accurate measure of peak expiratory flow. Choice A is incorrect because using the device before taking medication may not reflect the actual peak flow, as medication can affect lung function. Choice B is incorrect as using the device during asthma attacks may not be feasible or safe, as the focus during an attack should be on managing symptoms rather than measuring peak flow. Choice D is incorrect because using the device after eating may not provide an accurate measurement of peak flow, as digestion can affect lung function temporarily.
