Pediatric Practice Exam HESI

Correct Answer: D

Rationale: Full-thickness burns are characterized by a leathery, dry appearance with numbness due to nerve damage. Choice A describes characteristics of superficial burns, which are not full-thickness. Choice B describes characteristics of partial-thickness burns with intact blisters, not full-thickness burns. Choice C describes characteristics of partial-thickness burns with blistering and swelling, not full-thickness burns.

Correct Answer: C

Rationale: The priority nursing intervention for a 4-year-old child admitted with epiglottitis is to keep the child NPO (nothing by mouth). This is crucial to prevent further airway compromise due to the inflamed epiglottis. Administering antibiotics may be necessary but is not the priority at this moment. Providing humidified oxygen can support oxygenation but does not address the immediate risk of airway obstruction. Positioning the child upright may help with breathing but does not address the risk of aspiration. Keeping the child NPO is essential to maintain a patent airway and prevent complications associated with epiglottitis.

Correct Answer: B

Rationale: In cases of potential poisoning, immediate guidance from professionals is crucial. Administering syrup of ipecac is no longer recommended routinely due to potential risks and lack of benefit. Taking the child to the emergency department is necessary in severe cases but may not always be the immediate action needed. Giving the child bread dipped in milk is not an appropriate method to manage poisoning and could potentially worsen the situation. Therefore, the most appropriate action for the nurse to recommend is to call the poison control center for expert advice on managing the situation.

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.
