Pediatric HESI Practice Questions

Correct Answer: D

Rationale: The varicella vaccine is specifically designed to prevent chickenpox. Measles, mumps, and rubella are prevented by different vaccines (MMR vaccine for measles, mumps, and rubella). Therefore, the correct answer is chickenpox (varicella). It is crucial for healthcare professionals to provide accurate information about vaccines to help ensure the health and well-being of individuals.

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 a nonspecific test for inflammation and not specific to atopic dermatitis. Choice B, potassium hydroxide prep, is used to diagnose fungal infections like tinea versicolor, not atopic dermatitis. Choice C, wound culture, is not typically indicated for the diagnosis of atopic dermatitis as it is a chronic inflammatory skin condition rather than an infectious process.

Correct Answer: B

Rationale: Administering factor VIII in the morning on scheduled days ensures that there is a consistent level of the plasma component throughout the day, especially when the child is active. This timing helps to maintain adequate levels of factor VIII to prevent bleeding episodes. Choice A is incorrect because administering factor VIII only when a bleed is suspected would not provide the consistent prophylactic coverage needed for children with hemophilia. Choice C is incorrect as bedtime administration may not be practical for ensuring the plasma component is available during the child's active hours. Choice D is incorrect because administering factor VIII on a regular schedule, rather than at specific times of the day, may not optimize its effectiveness in preventing bleeding episodes.

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: 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.
