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: Point tenderness is the most reliable indicator of a possible fracture in a child. It refers to localized pain at a specific point, indicating a potential bone injury. Lack of spontaneous movement (Choice A) is non-specific and can be due to various reasons. Bruising (Choice C) may be present in fractures but is not as specific as point tenderness. Inability to bear weight (Choice D) can also be seen in fractures but may not always be present, making it less reliable compared to point tenderness.

Correct Answer: B

Rationale: A cross-cut nipple is the most appropriate method to feed an infant born with a unilateral cleft lip and palate. Using a cross-cut nipple allows for easier feeding by modifying the flow of milk, which helps in reducing the risk of aspiration in infants with this condition. Plastic spoon, parenteral infusion, and rubber-tipped syringe are not suitable for feeding infants with cleft lip and palate. Feeding an infant with a cleft lip and palate requires special considerations to ensure safe and effective nutrition delivery.

Correct Answer: C

Rationale: The correct answer is C because using echolalia (repeating words or phrases) is not typical for a 2-year-old and may indicate the need for further evaluation. Choices A, B, and D are within the expected developmental skills for a 2-year-old. While a 2-year-old may not be able to stand on one foot for an extended period, it is not a concerning developmental milestone at this age. Building a tower of 7 blocks and coloring outside the lines of a picture are both age-appropriate activities that demonstrate fine motor skills and creativity, respectively. However, echolalia at this age could be a sign of an underlying communication or developmental issue that warrants further assessment and monitoring.

Correct Answer: D

Rationale: For a child with diabetes mellitus, following a specific meal plan is crucial for managing blood glucose levels effectively. This helps in maintaining stable blood sugar levels and preventing complications associated with the condition. Monitoring blood glucose levels daily and recognizing signs of hypoglycemia are also important aspects of managing diabetes; however, adherence to a specific meal plan plays a fundamental role in overall diabetes care. Administering insulin based on blood glucose levels alone is not recommended without a specific plan provided by healthcare providers.
