Pediatric HESI Practice Questions

Correct Answer: B

Rationale: The primary function of the endocrine system is hormonal secretion. This system is responsible for producing and releasing hormones that regulate various bodily functions such as growth, metabolism, and mood. Choice A, regulation of water balance, is more related to the functions of the renal system rather than the endocrine system. Choice C, cellular metabolism, is a general cellular process that involves various systems, not specific to the endocrine system. Choice D, growth stimulation, though hormones can influence growth, it is not the primary function of the endocrine system. Therefore, the correct answer is B.

Correct Answer: A

Rationale: After a prolonged hospitalization, a toddler may exhibit excessively demanding behavior as they readjust to being home. This behavior can be a result of the child seeking extra attention and reassurance after a stressful experience. Choices B, C, and D are incorrect because hostility, cheerfulness with shallow attachment, and withdrawal without emotional ties are less likely outcomes in this situation and do not align with common reactions of toddlers after hospitalization.

Correct Answer: C

Rationale: The correct answer is to advise the parent to call the poison control center. When a child ingests household bleach, it is important to seek guidance from professionals who can provide specific and immediate advice on managing the situation. Administering activated charcoal (Choice A) is not recommended for household bleach ingestion. Inducing vomiting immediately (Choice B) can lead to further complications and is not the recommended first response. Taking the child to the emergency department (Choice D) should be done based on the advice received from the poison control center.

Correct Answer: B

Rationale: Bone growth primarily occurs in the epiphysis, which is the area where growth plates are located. The epiphysis is responsible for longitudinal bone growth. The growth plate, also known as the physis, is the cartilaginous region in the metaphysis where bone growth occurs. The metaphysis is the area between the epiphysis and diaphysis where bone lengthening occurs, but it is not the primary site of bone growth. Therefore, choices A, C, and D are incorrect.

Correct Answer: A

Rationale: Administering bronchodilators is a crucial nursing intervention for a child with asthma because it helps to open the airways and ease breathing during an asthma attack. Bronchodilators are medications that work by relaxing the muscles around the airways, making it easier for the child to breathe. Encouraging physical activity may exacerbate asthma symptoms in some cases due to increased respiratory effort and exposure to triggers. Monitoring oxygen saturation is important but does not address the immediate need of opening the airways during an asthma episode. Providing nutritional support is essential for overall health but is not the primary intervention needed in managing an acute asthma exacerbation.
