Correct Answer: A

Rationale: Friedman's structural functional theory outlines different functions of a family. The affective function, as defined by Friedman, pertains to meeting the love and belonging needs of each member. This includes emotional support, nurturing, and creating a sense of security within the family unit. Choices B, C, and D do not specifically address the affective function described in Friedman's theory. Choice B focuses on socialization and preparing children for adult roles, choice C relates to the economic function of a family, and choice D pertains to the instrumental function of providing physical care for health.

Correct Answer: D

Rationale: Poor wound healing is a common clinical manifestation of type 1 diabetes mellitus. High blood glucose levels in diabetes can impair the body's ability to heal wounds effectively. Choices A, B, and C are incorrect. Moist skin is not a typical clinical manifestation of type 1 diabetes; instead, skin may become dry due to dehydration. Weight gain is unlikely as type 1 diabetes is characterized by weight loss. Fluid overload is also uncommon in type 1 diabetes, which is more commonly associated with dehydration due to frequent urination.

Correct Answer: A

Rationale: Encouraging parents to express their concerns is the most supportive intervention as it allows them to process their emotions and provides an opportunity for the nurse to offer appropriate support and information. This choice focuses on validating the parents' feelings and creating an open communication channel. Choices B and C are incorrect as they can hinder the parents' emotional processing and may provide false reassurance. Choice D, showing postoperative photographs, may not be appropriate at this stage as it might not address the parents' current emotional needs and could induce anxiety or unrealistic expectations.

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: C

Rationale: In a child with a congenital cardiac malformation causing right-to-left shunting of blood, the nurse should expect an elevated hematocrit. This occurs because the body compensates for decreased oxygenation by producing more red blood cells. Proteinuria (Choice A) is not a typical clinical finding related to right-to-left shunting. Peripheral edema (Choice B) is more commonly associated with conditions causing volume overload, such as left-sided heart failure. Absence of pedal pulses (Choice D) is not directly related to right-to-left shunting but may be seen in conditions affecting peripheral circulation.
