  1. The CAGE questionnaire screens for which condition using four questions about cutting down, annoyance, guilt, and eye-openers?

    Answer: Alcohol use disorder

    The CAGE questionnaire is a validated 4-item screening tool for alcohol use disorder; a score of ≥2 indicates a clinically significant alcohol problem.

  2. A new drug reduces the absolute risk of myocardial infarction from 4% to 2% over 5 years. What is the number needed to treat (NNT)?

    Answer: 50

    NNT = 1 / absolute risk reduction = 1 / (0.04 − 0.02) = 1 / 0.02 = 50, meaning 50 patients must be treated to prevent one additional MI.

  3. Which BMI range defines Class I obesity in adults according to standard clinical guidelines?

    Answer: 30.0–34.9 kg/m²

    Class I obesity is defined as BMI 30.0–34.9 kg/m²; Class II is 35.0–39.9, and Class III (severe) is ≥40.0 kg/m².

  4. Which pharmacotherapy is considered the most effective first-line agent for smoking cessation due to partial agonism at nicotinic acetylcholine receptors?

    Answer: Varenicline (Chantix)

    Varenicline is the most efficacious first-line pharmacotherapy for smoking cessation, acting as a partial agonist at α4β2 nicotinic acetylcholine receptors to reduce cravings and withdrawal.

  5. Which malignancy is strongly associated with occupational asbestos exposure, typically presenting 20–40 years after exposure?

    Answer: Mesothelioma

    Mesothelioma is a malignant tumor of the pleura or peritoneum with a long latency period, and asbestos exposure is its predominant risk factor.

  6. Which of the following cardiovascular disease risk factors is considered modifiable through clinical and lifestyle intervention?

    Answer: Hypertension

    Hypertension is a major modifiable cardiovascular risk factor that can be reduced through lifestyle changes, antihypertensive medications, or both.

  7. In a cohort study, relative risk (RR) is calculated by comparing which of the following between exposed and unexposed groups?

    Answer: Incidence (rate) of disease

    Relative risk compares the incidence rate of disease in exposed individuals to that in unexposed individuals, making it the appropriate measure for cohort studies.
