Pediatric HESI Practice Questions

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: The correct answer is A. Most childhood cancers, such as leukemias and sarcomas, affect tissues rather than specific organs, unlike many adult cancers. Choice B is incorrect because childhood cancers may not always be localized when found. Choice C is incorrect as childhood cancers can be responsive to treatment, although treatment approaches may differ from adult cancers. Choice D is incorrect as the majority of childhood cancers cannot be prevented; however, certain risk factors can be managed to reduce the risk of developing cancer.

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.

Correct Answer: D

Rationale: During crowning, it is important to apply gentle pressure to the baby's head. This helps to prevent rapid delivery, which can lead to tearing and other complications for both the mother and the baby. Applying pressure also helps to control the delivery process, ensuring a safer and more controlled birth. Choices A, B, and C are incorrect because crowning does not signify the end of the second stage of labor, does not always occur immediately after the amniotic sac ruptures, and it is not safe to transport the patient during crowning, especially if the hospital is nearby, as rapid delivery can occur.

Correct Answer: A

Rationale: Monitoring fluid status is crucial for a child with congenital heart disease because these children are at risk of fluid overload, which can exacerbate their condition. Monitoring fluid intake and output helps prevent complications such as heart failure. Encouraging activity may be important, but it should be done cautiously and within limits due to the child's cardiac condition. Promoting a high-calorie diet is not typically a priority in congenital heart disease care unless there are specific indications. Maintaining oxygen therapy may be necessary in some cases but is not the primary intervention for managing congenital heart disease.
