Pediatric Practice Exam HESI

Correct Answer: B

Rationale: The correct approach for a child with a mild airway obstruction, respiratory distress, and normal skin color includes providing oxygen to support breathing, avoiding agitation that could worsen the situation, and arranging for transport to a healthcare facility. Option A is incorrect because abdominal thrusts are not recommended in a mild airway obstruction scenario, and back blows are typically used for choking. Option C is incorrect because assisting ventilations may not be necessary in a child with a strong cough and normal skin color. Option D is incorrect because chest thrusts are not recommended for a mild airway obstruction, and finger sweeps are used for foreign body airway obstructions.

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: C

Rationale: After eating, it is beneficial to place a child with GERD in a semi-Fowler's position. This position helps prevent reflux by keeping the child's head elevated above the stomach, reducing the chances of gastric contents flowing back into the esophagus. Placing the child supine (lying flat on their back) can worsen reflux symptoms by allowing gravity to work against the natural flow of gastric contents. Prone position (lying on the stomach) is not recommended due to the increased risk of aspiration. Trendelenburg position (feet elevated above head) is also inappropriate as it can lead to increased pressure on the abdomen, potentially worsening reflux symptoms.

Correct Answer: B

Rationale: Using a doll to demonstrate the procedure is the most appropriate preoperative teaching method for a 2-year-old child. It helps them understand what to expect in a non-threatening way by providing a visual representation of the upcoming surgery. Explaining the procedure in simple terms may be too abstract for a child of this age, as they may not fully comprehend verbal explanations. Showing pictures of the hospital environment may not be as effective as using a doll, as it may not provide a concrete understanding of the actual procedure. Allowing the child to play with medical equipment is unsafe and does not adequately prepare them for the surgery, as it may lead to misunderstandings or fear regarding the equipment's actual use during the surgery.

Correct Answer: A

Rationale: The correct answer is A: 'High fever and Koplik spots.' Rubeola (measles) is characterized by a high fever and the presence of Koplik spots, which are not seen in rubella (German measles). Choice B, rash on the trunk with pruritus, is more indicative of rubella. Choice C, nausea, vomiting, and abdominal cramps, are not specific to either rubeola or rubella. Choice D, characteristics of a cold followed by a rash, is not a typical presentation of rubeola or rubella.
