Pediatric HESI Practice Questions

Correct Answer: C

Rationale: The correct answer is C, Chickenpox (varicella). Chickenpox is a viral disease characterized by a highly pruritic rash that typically starts on the abdomen and then spreads to other parts of the body, including the face and proximal extremities. It can lead to complications such as pneumonia and encephalitis. Rubella (German measles) presents with a mild rash and swollen lymph nodes; Rubeola (measles) also presents with a rash but starts on the face before spreading downwards; Scarlet fever is caused by Group A Streptococcus bacteria and is characterized by a rash, fever, and sore throat.

Correct Answer: D

Rationale: The correct answer is D: "This is a lifelong problem, and it is recommended that dietary restrictions must be continued." Phenylketonuria (PKU) is a metabolic disorder where the body cannot process phenylalanine properly. The diet for PKU must be continued lifelong to prevent cognitive and developmental issues, as phenylalanine buildup can cause irreversible damage. Choice A is incorrect because the nurse should provide information about the lifelong nature of the dietary restrictions for PKU. Choice B is incorrect as it suggests reintroducing protein-containing foods, which is not recommended for individuals with PKU. Choice C is incorrect as it underestimates the duration of the necessary dietary restrictions for PKU.

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: B

Rationale: Establishing a bedtime routine is the most appropriate suggestion for a parent seeking help with a child experiencing night terrors. Bedtime routines can create a sense of security and predictability for the child, potentially reducing the frequency of night terrors. Encouraging the child to talk about the night terrors (Choice A) may not be effective during the episode as the child is usually not fully awake. Allowing the child to sleep with the parents (Choice C) may inadvertently reinforce the behavior and hinder the child's ability to learn to self-soothe. Waking the child during the night (Choice D) may disrupt the sleep cycle and exacerbate the night terrors.

Correct Answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.
