Correct Answer: B

Rationale: Acetaminophen is extensively metabolized in the liver. An overdose of acetaminophen can lead to severe liver damage and even liver failure, which can be life-threatening. Choices A, C, and D are incorrect because although prolonged use of acetaminophen may lead to an increased risk of renal dysfunction, a single overdose does not typically cause life-threatening abnormalities in the lungs, kidneys, or adrenal glands.

Correct Answer: D

Rationale: In diagnostic genetic counseling, clients may face difficult decisions based on test results. Terminating the pregnancy is a choice some clients may consider if severe abnormalities are detected. Preparing for the birth of a child with special needs involves getting ready to care for a child who may require extra attention and support. Accessing support services before the birth can help clients connect with resources and professionals for assistance during and after the pregnancy. Completing the grieving process before birth is not typically a choice made in the context of genetic counseling. The grieving process often starts or continues after distressing results and can extend beyond the birth of the child. Therefore, the correct answer is completing the grieving process before the birth.

Correct Answer: C

Rationale: An 18-month-old child should have approximately 12 teeth. Children typically start getting teeth around 6 months of age. By subtracting 6 from the number of months in the child's age, you can calculate the expected number of teeth. For an 18-month-old child, 18 - 6 = 12 teeth. Therefore, the correct answer is 12 teeth. Choices A, B, and D are incorrect because they do not align with the expected dental development in an 18-month-old child.

Correct Answer: A

Rationale: When preparing for transillumination of the scrotum, the nurse should obtain a flashlight and darken the room. This is done to allow the strong flashlight to be shined from behind the scrotal contents. Normal scrotal contents do not appear on transillumination. Instructing the client to drink fluids or to take deep breaths and bear down is not part of the preparation for this procedure. Additionally, it is not necessary to inform the client that the procedure is uncomfortable as transillumination is a painless procedure.

Correct Answer: B

Rationale: Kleinman's Explanatory Model of Health and Illness is significant because it emphasizes the crucial role that popular and folk domains of influence play in shaping individuals' understanding of health and illness. Kleinman distinguishes between disease, which is the biomedical understanding of health problems, and illness, which is the individual's personal interpretation of their health condition. By focusing on the cultural factors that influence these domains of influence, Kleinman's model underscores the impact of cultural beliefs and practices on health perceptions. Choice A is incorrect because the model goes beyond just family health beliefs. Choice B is more precise as it emphasizes the broader influence of culture. Choice C highlights the correct significance of popular and folk domains of influence, making it the correct choice. Choice D is incorrect as the model's significance lies in cultural domains, not educational structure.
