HESI Pediatrics Practice Exam

Correct Answer: C

Rationale: The correct answer is C: 'Enzymes should be taken before or with meals.' Pancreatic enzymes should be taken before or with meals to assist with digestion in children with cystic fibrosis. This timing helps maximize the effectiveness of the enzymes in breaking down nutrients from food. Giving the enzymes after meals (choice A) may not provide the necessary support for digestion. Mixing the enzymes with hot food or drinks (choice B) is not recommended as it may affect the enzymes' efficacy. Avoiding giving enzymes with any food or drink (choice D) is incorrect as enzymes need to be taken in conjunction with meals to aid in digestion.

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: In a child with ear pain and fever, asking about a runny nose is important to assess if the ear pain is associated with a respiratory infection, such as otitis media. This information can guide further assessment and treatment decisions. Choice B is incorrect because cleansing purulent exudate should be done by a healthcare provider, not the nurse. Choice C is incorrect as topical antibiotics should only be applied under healthcare provider's orders. Choice D is not the priority at this moment, as the immediate concern is assessing the association between the ear pain and a possible respiratory infection.

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: B

Rationale: When screening a 5-year-old for strabismus, directing the child through the six cardinal positions of gaze is the most appropriate action. This method helps the nurse to assess eye alignment, which is crucial in identifying any misalignment that may indicate strabismus. Choices A, C, and D are incorrect. Having the child identify colored patterns on polychromatic cards is more related to visual acuity testing rather than strabismus screening. Inspecting the child for the setting sun sign is not a standard method for strabismus screening. Observing the child for blank, sunken eyes is not specific to strabismus assessment.
