Pediatric HESI Test Bank

Correct Answer: D

Rationale: The correct answer is D: DTaP, IPV, MMR. Before starting kindergarten, the child should receive boosters of DTaP, IPV, and MMR to ensure ongoing protection against diphtheria, tetanus, pertussis, polio, measles, mumps, and rubella. Choice A is incorrect because it includes HepB instead of MMR. Choice B is incorrect as it includes HepB instead of MMR and DTaP instead of IPV. Choice C is incorrect as it includes Hib instead of IPV.

Correct Answer: D

Rationale: The correct answer is D. Infants have a higher extracellular fluid requirement per unit of body weight, making them more susceptible to dehydration and electrolyte imbalances during illnesses such as diarrhea. Choice A is incorrect because cellular metabolism being unstable is not the primary explanation for the symptoms described. Choice B is incorrect as the proportion of water in the body alone does not fully explain the increased risk of dehydration in infants. Choice C is incorrect because while renal function is immature in children, it is not the most relevant factor in this scenario compared to the increased fluid requirements.

Correct Answer: A

Rationale: Abdominal swelling is frequently the initial assessment finding associated with a Wilms tumor. This swelling is caused by the tumor's mass in the kidney, leading to abdominal distension. Weight gain (Choice B) is less likely as a primary finding, as it may occur later due to tumor growth or fluid retention. Hypotension (Choice C) is not typically associated with Wilms tumor unless severe complications like hemorrhage develop. Increased urinary output (Choice D) is not a common initial finding; instead, hematuria or other urinary changes may be observed later in the disease process.

Correct Answer: B

Rationale: Upright positioning is the most appropriate intervention to promote maximum chest expansion in a child with Duchenne muscular dystrophy. By keeping the child in an upright position, lung expansion is maximized, which improves breathing efficiency. Deep-breathing exercises may help with overall lung function but do not directly promote chest expansion. Coughing and chest percussion are more related to airway clearance and do not specifically address maximizing chest expansion.

Correct Answer: C

Rationale: The correct answer is to measure the dose with a proper measuring device. Using a household spoon can lead to inaccurate dosing, which can be dangerous. Administering the medication with food or only when the child has a high fever are not the essential instructions related to the safe and effective administration of acetaminophen.
