HESI Pediatrics Quizlet

Correct Answer: A

Rationale: The correct answer is giving a pacifier to the newborn. Sucking is a natural reflex and a source of comfort for newborns, especially postoperatively. Offering a pacifier can help meet their developmental needs by providing comfort and a soothing mechanism. Placing a mobile over the crib (choice B) may provide visual stimulation but does not directly address the newborn's developmental needs for comfort and self-soothing. Providing a soft, cuddly toy (choice C) may offer some comfort but may not be as effective in meeting the specific developmental need for sucking postoperatively. Warming the newborn's formula before feeding (choice D) relates more to feeding practices than directly addressing a major developmental need in the postoperative period.

Correct Answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.

Correct Answer: C

Rationale: The correct statement is that infants may have difficulty balancing glucose and electrolytes because their endocrine systems are immature. Newborns have developing endocrine glands that are not yet fully functional, leading to challenges in maintaining glucose and electrolyte balance. Choice A is incorrect as endocrine glands start developing in the first trimester, not the third trimester. Choice B is incorrect as endocrine glands are not fully functional at birth. Choice D is incorrect because while a child's endocrine system indeed plays a vital role in growth and development, the specific focus of the question is on the challenges infants face due to immature endocrine glands.

Correct Answer: C

Rationale: The correct answer is C: Osgood-Schlatter disease. This condition is a common overuse injury that affects the knee. Osgood-Schlatter disease typically occurs in children and adolescents who are involved in activities that require frequent running, jumping, and kicking. It is characterized by pain, swelling, and tenderness at the tibial tuberosity, where the patellar tendon inserts into the tibia. Choice A, Dislocated radial head, is not an overuse disorder but rather a form of elbow injury where the head of the radius bone is displaced from its normal position. Choice B, Transient synovitis of the hip, is a self-limiting condition that causes hip pain and limping in children. It is not typically considered an overuse disorder. Choice D, Scoliosis, is a condition characterized by an abnormal lateral curvature of the spine. While it may be related to certain activities or postures, it is not primarily classified as an overuse disorder.

Correct Answer: D

Rationale: When counseling a couple at risk of genetic abnormalities, it is crucial to present information in a nondirective manner. This approach allows the couple to make informed decisions without feeling pressured or influenced. Gathering information from at least three generations (Choice A) may be relevant for genetic counseling but is not the most critical aspect in this scenario. Informing the couple of the need for a wide range of information (Choice B) is too general and does not address the specific approach needed in this situation. Maintaining the confidentiality of the information (Choice C) is important but not the top priority compared to presenting information in a nondirective manner.
