Pediatric HESI Practice Questions

Correct Answer: B

Rationale: The correct answer is 'Hormonal secretion' (Choice B). The primary function of the endocrine system is to secrete hormones that regulate various bodily functions such as metabolism, growth, and reproduction. Choice A, 'Regulation of water balance,' is primarily controlled by the kidneys and the urinary system, not the endocrine system. Choice C, 'Cellular metabolism,' is more directly related to the functions of individual cells rather than the overall function of the endocrine system. Choice D, 'Growth stimulation,' is a function that can be influenced by hormones secreted by the endocrine system, but it is not the primary function of the system.

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: C

Rationale: During the stage of protest, children may exhibit distress and cling to familiar figures, resisting interactions with others. The most appropriate nursing intervention is to sit by the crib, offer comfort, and wait until the child's anxiety decreases before proceeding with bathing. This approach allows the child to feel supported and gradually transition to accepting care. Choice A is incorrect because forcing comfort may escalate the child's distress. Choice B is inappropriate as it disregards the child's emotional state and rushes into the bathing procedure. Choice D is not ideal as it suggests delaying care for an extended period, which may not address the child's immediate needs for comfort and hygiene.

Correct Answer: A

Rationale: The correct action would be to notify the doctor immediately. Unrelenting pain despite medication can indicate compartment syndrome, which is a medical emergency requiring immediate attention. Applying ice or elevating the arm may not address the potential serious underlying issue of compartment syndrome. Giving additional pain medication without further assessment could delay necessary intervention and potentially worsen the condition.

Correct Answer: B

Rationale: Invasive burn cellulitis is characterized by the burn developing a dark brown, black, or purplish color with discharge and a foul odor. This description aligns with the symptoms observed in the 15-year-old boy. Burn wound cellulitis (Choice A) typically presents with erythema, edema, warmth, and tenderness at the burn site, without the characteristic changes seen in this case. Burn impetigo (Choice C) is a superficial infection characterized by honey-colored crusts, not consistent with the purplish color and foul odor described. Staphylococcal scalded skin syndrome (Choice D) is a condition caused by exotoxins produced by Staphylococcus aureus, leading to widespread desquamation of the skin, but it does not typically present with the specific findings mentioned in the scenario.
