Pediatric HESI Practice Questions

Correct Answer: A

Rationale: A webbed neck is a classic physical characteristic seen in individuals with Turner syndrome, a genetic condition that results from a missing or partially missing X chromosome in females. This distinctive feature occurs due to excess skin on the neck and is a key clinical clue for healthcare providers. Microcephaly (choice B) refers to a small head size and is not typically associated with Turner syndrome. Gynecomastia (choice C) is the enlargement of breast tissue in males and is not a common finding in Turner syndrome. Cognitive delay (choice D) involves intellectual or developmental delays and is not a specific feature of Turner syndrome.

Correct Answer: C

Rationale: In cases of exstrophy of the bladder, a moist sterile dressing is the most appropriate choice to protect the exposed bladder tissue. Moist sterile dressings help maintain a clean environment, prevent infection, and promote healing. A loose diaper (Choice A) may not provide adequate protection and may lead to contamination. Dry gauze dressing (Choice B) could adhere to the wound and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) is not ideal as it may not provide the necessary barrier against infection and could potentially cause irritation.

Correct Answer: C

Rationale: The correct answer is Chickenpox (varicella). This viral disease typically starts with malaise and a highly pruritic rash that begins on the abdomen and then spreads to the face and proximal extremities. Chickenpox can result in serious complications such as pneumonia and encephalitis. Rubella (German measles) presents with a milder rash and is less pruritic than chickenpox. Rubeola (measles) is characterized by a rash that spreads from the head to the trunk. Scarlet fever is caused by group A Streptococcus bacteria and is not a viral illness.

Correct Answer: B

Rationale: The correct technique for opening the airway of an infant with no suspected neck injury is to tilt the head back without hyperextending the neck. This method helps to keep the airway open without risking injury to the infant's delicate neck structures. Choice A, lifting up the chin and hyperextending the neck, can potentially harm the infant's neck. Choice C, gently lifting the chin while maintaining slight flexion of the neck, is not as effective as tilting the head back. Choice D is incorrect as infants require a different approach compared to older children or adults due to their anatomical differences.

Correct Answer: A

Rationale: In Friedman's structural functional theory, the affective function of a family involves meeting the love and belonging needs of each member. This includes emotional support, care, and connections that contribute to the overall well-being of the family unit. Choice B is incorrect as it pertains more to the socialization function of the family, where children learn societal roles. Choice C relates to the economic function of the family, ensuring resources are available and allocated appropriately. Choice D focuses on the instrumental function of the family, which involves meeting the physical needs and health of its members.
