Correct Answer: C

Rationale: The correct answer is C: 'Health providers need to be aware of the roles and decision-making process within the family.' To provide services effectively, health providers must understand the dynamics within a family, including who makes decisions and how roles are distributed. This knowledge helps them tailor their services to meet the needs and preferences of the whole family. Choices A and B are incorrect because contacting the wife's relatives or seeking the services of a traditional healer may not necessarily align with providing effective services based on family dynamics. Choice D is also incorrect as door-to-door sensitization may not directly address the internal dynamics of a family.

Correct Answer: A

Rationale: The first menstrual period, known as menarche, typically occurs between the ages of 9 and 15 years. This marks the onset of puberty in females. Choices B, C, and D are incorrect because the first menstrual period does not occur as early as 2 years old, 1 year old, or as late as 18 to 20 years old.

Correct Answer: D

Rationale: Sterilization is considered the most effective method of contraception because it permanently prevents pregnancy. Barrier methods, hormonal pills, and IUDs are highly effective as well, but they are reversible methods and may have a higher failure rate compared to sterilization.

Correct Answer: D

Rationale: Human chorionic gonadotropin (hCG) is the hormone detected in pregnancy tests. During pregnancy, the placenta produces hCG, which can be detected in the urine or blood to confirm pregnancy. Estrogen and progesterone are also essential hormones in pregnancy but are not typically used for pregnancy tests. Luteinizing hormone (LH) is involved in the menstrual cycle and ovulation, not pregnancy.
