Correct Answer: B

Rationale: The correct answer is B: Invasive burn cellulitis. Invasive burn cellulitis presents with the burn developing a dark brown, black, or purplish color with discharge and a foul odor. Burn wound cellulitis (choice A) typically involves redness, warmth, and swelling around the burn site. Burn impetigo (choice C) is a superficial infection characterized by honey-colored crusting. Staphylococcal scalded skin syndrome (choice D) is a condition caused by exotoxins from Staphylococcus aureus, leading to widespread skin peeling.

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 worsen their condition. Monitoring fluid intake and output helps prevent complications like congestive heart failure. Encouraging activity (Choice B) should be individualized based on the child's condition and tolerance, as excessive activity can strain the heart. Promoting a high-calorie diet (Choice C) is not typically recommended for children with congenital heart disease unless specifically indicated, as excessive weight gain can worsen their cardiac function. Maintaining oxygen therapy (Choice D) may be necessary in some cases, but monitoring fluid status is a more fundamental aspect of care for children with congenital heart disease.

Correct Answer: D

Rationale: The most accurate way to determine a therapeutic dose for children is based on their weight rather than age. Weight-based dosing helps ensure that the child receives the appropriate amount of medication for their body size, which is crucial for safety and effectiveness. Age-based dosing can lead to underdosing or overdosing, as children of the same age can have significantly different weights. Choice A is incorrect because even small variations in dosages can have significant effects on a child's health. Choice B is incorrect as acetaminophen can be appropriate when used correctly for fever management in children. Choice C is incorrect as children's weights can vary greatly within the same age group, making weight-based dosing more precise and individualized.

Correct Answer: D

Rationale: Poor wound healing is a common clinical manifestation of type 1 diabetes mellitus. Elevated blood glucose levels in diabetes can lead to impaired wound healing by affecting various cellular processes involved in the healing cascade. Moist skin (Choice A) is not typically associated with type 1 diabetes mellitus. Weight gain (Choice B) is more commonly seen in type 2 diabetes due to insulin resistance. Fluid overload (Choice C) is not a typical clinical manifestation of type 1 diabetes mellitus. Therefore, the correct answer is poor wound healing.

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.
