Correct Answer: C

Rationale: Positive fibrin split products are indicative of disseminated intravascular coagulation (DIC). In DIC, there is widespread clotting and subsequent consumption of clotting factors, leading to the formation of fibrin split products. A shortened prothrombin time (Choice A) is not typically seen in DIC as it indicates faster clotting, which is opposite to the pathophysiology of DIC. An increased fibrinogen level (Choice B) may be observed in the early stages of DIC due to the compensatory increase in production, but it is not a definitive indicator. Increased platelets (Choice D) may be seen in the early stages of DIC due to the body's attempt to compensate for clot formation, but it is not a specific finding for DIC.

Correct Answer: D

Rationale: When counseling a couple about the possibility of having a child with a genetic abnormality, it is vital for the nurse to present information in a nondirective manner. This approach empowers the couple to make decisions based on their values and preferences, respecting their autonomy. Gathering information from three generations (Choice A) may not be necessary and might overwhelm the couple with unnecessary data. Informing the family about the need for a wide range of information (Choice B) is not as critical as supporting their decision-making process through a nondirective approach. While maintaining confidentiality (Choice C) is crucial, it is not the most important aspect compared to ensuring the couple can make informed choices that align with their beliefs and wishes.

Correct Answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.

Correct Answer: A

Rationale: The correct answer is A. Cystic fibrosis is a genetic disorder that primarily affects the respiratory and digestive systems. It results in the production of thick, sticky mucus that can clog the lungs and obstruct the pancreas. This explanation is crucial for parents to understand the impact of the condition on their child's health. Choice B is incorrect because cystic fibrosis is not an autoimmune disorder. Choice C is partially correct in that cystic fibrosis is a genetic disorder, but it requires a comprehensive management approach beyond just medication. Choice D is incorrect as cystic fibrosis is not caused by prenatal exposure to toxins but rather by inheriting specific genetic mutations.

Correct Answer: A

Rationale: The correct answer is to maintain a structured routine. Children with autism spectrum disorder benefit greatly from structured routines as they provide a sense of stability and predictability, which can help reduce anxiety and improve behavior. Encouraging social interaction (Choice B) is important but may need to be approached in a structured manner to prevent overwhelming the child. Positive reinforcement (Choice C) is also beneficial for behavior management but may not address the overall need for routine and predictability that is crucial for children with autism. Using a communication board (Choice D) may be helpful for facilitating communication, but establishing and maintaining a structured routine is fundamental for supporting the child's development and well-being in managing their autism spectrum disorder.
