Pediatric Practice Exam HESI

Correct Answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis due to impaired respirations leading to the retention of carbon dioxide, which combines with water to form carbonic acid. This results in the pH imbalance characterized by an excess of carbonic acid. Choices A, B, and D are incorrect. Metabolic alkalosis (Choice A) is not typically associated with severe asthma attacks; respiratory alkalosis (Choice B) would involve a decrease, not an increase, in carbon dioxide levels; and metabolic acidosis (Choice D) is not the primary acid-base imbalance seen in severe asthma attacks.

Correct Answer: B

Rationale: The correct preoperative teaching for a 2-year-old child undergoing surgery involves using a doll to demonstrate the procedure. This method helps the child understand what to expect in a non-threatening and visual way, making the experience less intimidating. Explaining the procedure in simple terms (Choice A) may not effectively convey the details to a young child. Showing pictures of the hospital environment (Choice C) may not directly address the surgical procedure itself. Allowing the child to play with medical equipment (Choice D) can be unsafe and may not effectively prepare the child for the surgery.

Correct Answer: C

Rationale: The correct nursing diagnosis would be 'Grieving related to the child's poor prognosis.' Trisomy 18 is associated with a poor prognosis, and families often experience feelings of grief and loss when dealing with such a diagnosis. The choice 'Interrupted family process' does not directly address the emotional response to the prognosis. 'Deficient knowledge' may be a concern but does not address the emotional aspect of dealing with a poor prognosis. 'Ineffective coping related to stress from providing care' focuses more on the caregiver's ability to cope rather than the family's response to the child's condition.

Correct Answer: C

Rationale: Elevating the affected area above the level of the heart is the correct supportive measure for a child with hemophilia who has experienced trauma. This action helps reduce bleeding and swelling by promoting venous return and preventing further pooling of blood in the affected area. Applying warm, moist compresses (Choice A) may not be recommended as it can potentially increase bleeding by dilating blood vessels. Applying pressure for at least 1 minute (Choice B) can be helpful for minor cuts or wounds but may not be as effective in managing bleeding in a child with hemophilia. Beginning passive range-of-motion (Choice D) should be avoided as it can exacerbate bleeding and cause further damage in a child with hemophilia.

Correct Answer: D

Rationale: Following a structured meal plan is essential for managing diabetes mellitus. It helps regulate blood glucose levels and ensures proper nutrition. Monitoring blood glucose levels daily is important, not just once a day, to maintain control. Administering insulin based on blood glucose levels is crucial but should be done as per the healthcare provider's instructions, not only when blood glucose is high. Recognizing signs of hypoglycemia is important, but it is equally vital to prevent hypoglycemia by adhering to a consistent meal plan and insulin regimen.
