A) Cost-Minimization Analysis (CMA) B) Cost-Benefit Analysis (CBA) C) Cost-Utility Analysis (CUA) D) Cost-Effectiveness Analysis (CEA)

• Correct Answer: C
• Rationale: Cost-Utility Analysis measures health outcomes using metrics like QALYs or DALYs, which combine survival time with health-related quality of life into a single index.

Q89. In health insurance frameworks, what does the term “Moral Hazard” mean? A) The criminal intention of a doctor to prescribe counterfeit medicines B) A change in behavior that occurs when individuals use more healthcare services or take fewer health precautions because they are insulated from the full financial cost of care by insurance C) The refusal of an insurance agency to pay for a child’s vaccination cost D) The ethical decision of a nurse to provide free emergency care

• Correct Answer: B
• Rationale: Moral hazard occurs when having insurance insulation alters a person’s behavior, leading them to use services less economically or take higher health risks because they do not bear the direct marginal costs.

Q90. Which of the following global health metrics represents the sum of years of potential life lost due to premature mortality and years of productive life lived with a disability (YLD) due to a disease condition? A) Life Expectancy at Birth B) Disability-Adjusted Life Year (DALY) C) Crude Death Rate D) Total Fertility Rate

• Correct Answer: B
• Rationale: One DALY represents the loss of the equivalent of one year of full health. It is a composite index that measures the total burden of disease by combining premature mortality (YLL) and years lived with disability (YLD).
