Correct Answer: A

Rationale: The inability to copy a square at 3 years old indicates a potential developmental delay in fine motor skills. At this age, children should be able to copy basic shapes like circles and crosses. Hopping on one foot is typically expected around the age of 4, catching a ball reliably around 5, and using a spoon effectively by 2-3 years old. Therefore, choices B, C, and D are not as indicative of a developmental delay at 3 years old as the inability to copy a square.

Correct Answer: C

Rationale: A moist sterile dressing should be used to protect the exposed bladder tissue from infection and injury. Exstrophy of the bladder requires careful management to prevent complications such as infection. A loose diaper (Choice A) may not provide adequate protection or prevent infection. Dry gauze dressing (Choice B) may not be ideal as it could adhere to the exposed area and cause trauma upon removal. Petroleum jelly gauze pad (Choice D) may not be suitable as it can trap moisture and increase the risk of infection.

Correct Answer: C

Rationale: The priority nursing intervention for a child with hemophilia experiencing a bleeding episode is administering factor VIII. Hemophilia is a genetic disorder characterized by a deficiency in clotting factors, such as factor VIII. Administering factor VIII replacement therapy is crucial to stop or control bleeding in individuals with hemophilia. Options A, B, and D are important aspects of patient care but do not take precedence over addressing the underlying cause of the bleeding in a child with hemophilia, which is the deficiency of factor VIII.

Correct Answer: C

Rationale: During the stage of protest, children may display distress when separated from their primary caregiver. Sitting by the crib and providing comfort when the child is less anxious is an appropriate intervention. Choice A is incorrect because attempting to hold the child while they are in distress may escalate the situation. Choice B is inappropriate as it ignores the child's emotional distress and proceeds with a task that can wait. Choice D is not the best option as postponing the bath for a day is not necessary; instead, addressing the child's emotional needs promptly is crucial in this situation.

Correct Answer: A

Rationale: In Friedman's structural functional theory, the affective function of a family involves meeting the love and belonging needs of each member. This includes emotional support, care, and connections that contribute to the overall well-being of the family unit. Choice B is incorrect as it pertains more to the socialization function of the family, where children learn societal roles. Choice C relates to the economic function of the family, ensuring resources are available and allocated appropriately. Choice D focuses on the instrumental function of the family, which involves meeting the physical needs and health of its members.
