HESI Pediatrics Practice Exam

Correct Answer: B

Rationale: The correct answer is B: 'I will give my baby iron-fortified cereal.' Iron-fortified cereal is an excellent source of iron for infants, aiding in the prevention of iron deficiency anemia. Choice A is incorrect as whole cow's milk should not be introduced until the child is at least 12 months old to prevent iron deficiency. Choice C is incorrect because giving fruit juice between meals can interfere with iron absorption. Choice D is incorrect as giving water with meals can decrease nutrient intake. Therefore, the best choice to prevent iron deficiency anemia in a 9-month-old infant is to give them iron-fortified cereal.

Correct Answer: A

Rationale: An increase in urine output is a reliable indicator that the child's hydration status is improving. Adequate urine output signifies that the kidneys are functioning properly and that the body is effectively eliminating waste and excess fluids, indicating improved hydration levels. The other options are not as direct indicators of hydration status. Skin turgor and weight changes can be influenced by various factors, and stable vital signs do not specifically reflect hydration status.

Correct Answer: D

Rationale: When a child presents with fever, sore throat, swollen red spots, and fluid-filled blisters, it may indicate a contagious viral infection. In such cases, implementing transmission precautions is crucial to prevent the spread of the infection to others in the pediatric clinic or community. Obtaining a fluid culture from the blisters (Choice A) may not be necessary at the initial stage without knowing the cause of the infection. Administering a fever-reducing medication (Choice B) may help manage symptoms but doesn't address the need for preventing transmission. Covering the drainage vesicles with a dressing (Choice C) may provide comfort to the child but does not directly address the risk of transmission to others.

Correct Answer: B

Rationale: In this scenario, the child's symptoms of fever, rash, and swollen joints following an untreated sore throat two weeks ago are indicative of rheumatic fever. Rheumatic fever can develop as a complication of untreated streptococcal infections, leading to systemic inflammation and affecting various organs, including the joints. This condition manifests with symptoms such as fever, rash, and swollen joints, aligning with the child's presentation in this case. Scarlet fever typically presents with a sandpapery rash and strawberry tongue but does not involve joint inflammation. Kawasaki disease presents with fever, rash, and mucous membrane changes but does not typically involve joint swelling. Juvenile rheumatoid arthritis can cause joint swelling but is not directly linked to a recent untreated sore throat.

Correct Answer: A

Rationale: Keeping the infant away from people with colds is crucial to prevent the spread of respiratory infections, especially for infants recently hospitalized with bronchiolitis. This precaution helps protect the baby from further illnesses and promotes recovery. The other choices are incorrect because it is important to complete the prescribed medication course even if the baby seems better to ensure the infection is fully treated (Choice B). Solid foods are usually introduced around six months of age, so avoiding them entirely may not be necessary (Choice C). Placing the baby to sleep on their back is a safe sleep practice to prevent sudden infant death syndrome (SIDS) but may not directly help with breathing in the context of bronchiolitis (Choice D).
