1. Which of the following best describes epidemiology?

A. The study of the distribution and determinants of health-related states or events in specified populations.
B. The study of the distribution and determinants of health-related states or events in specified populations and the application of this study to control health problems.
C. The study of how social factors influence health outcomes.
D. The study of how health systems and services impact population health.

Correct answer: B

Rationale: Epidemiology is defined as the study of the distribution and determinants of health-related states or events in specified populations, as well as the application of this study to control health problems. This field focuses on identifying patterns and causes of health and disease in order to develop strategies for prevention and control.

2. Which is a primary focus of health promotion activities?

A. Preventing the onset of disease
B. Detecting diseases early to improve outcomes
C. Managing chronic conditions to improve quality of life
D. Providing treatment for existing health conditions

Correct answer: A

Rationale: The correct answer is A: Preventing the onset of disease. Health promotion activities aim to prevent the occurrence of diseases by promoting healthy behaviors and creating supportive environments. By encouraging preventive measures such as vaccination, healthy eating, regular exercise, and stress management, individuals can reduce their risk of developing various illnesses. Detecting diseases early (choice B) focuses more on screening and early diagnosis rather than prevention. Managing chronic conditions (choice C) and providing treatment for existing health conditions (choice D) are important aspects of healthcare but are not the primary focus of health promotion activities, which emphasize disease prevention.

3. Directly Observed Treatment Short Course (D.O.T.S.) can do all of the following except:

A. Stop resistance to anti-TB drugs
B. Cure TB patients
C. Require hospitalization
D. Prevent new infection among children and adults

Correct answer: C

Rationale: Directly Observed Treatment Short Course (D.O.T.S.) is an effective strategy for treating tuberculosis (TB) that involves ensuring patients receive and complete their medication regimen under observation. DOTS aims to cure TB patients, stop resistance to anti-TB drugs, and prevent new infections among children and adults. One of the key advantages of DOTS is that it does not require hospitalization, allowing patients to receive treatment in their communities. Therefore, the statement that DOTS requires hospitalization is incorrect, making option C the correct answer.

4. Match the following terms in column A with the correct definition in Column B:

A. I. Topical anesthesia C. The agent is applied directly to the skin and mucous membranes of the skin. II. Epidural anesthesia D. Injecting the anesthesia in the epidural mater of the spinal cord.
B. II. Epidural anesthesia B. Anesthesia is introduced in the subarachnoid space at the lumbar area L4 and L5. I. Topical anesthesia C. The agent is applied directly to the skin and mucous membranes of the skin.
C. I. Topical anesthesia C. The agent is applied directly to the skin and mucous membranes of the skin. II. Epidural anesthesia D. Injecting the anesthesia in the epidural mater of the spinal cord.
D. I. Topical anesthesia C. The agent is applied directly to the skin and mucous membranes of the skin. II. Epidural anesthesia B. Anesthesia is introduced in the subarachnoid space at the lumbar area L4 and L5.

Correct answer: A

Rationale: Topical anesthesia involves applying the anesthetic agent directly to the skin and mucous membranes to numb the area. On the other hand, epidural anesthesia involves injecting the anesthetic into the epidural space surrounding the spinal cord. Therefore, the correct matches are: I. Topical anesthesia with the definition of applying the agent directly to the skin and mucous membranes (Choice C), and II. Epidural anesthesia with the definition of injecting the anesthesia in the epidural space around the spinal cord (Choice D).

5. Which strategy is most effective in improving health literacy among patients?

A. Using clear and simple language in communication
B. Providing health education sessions
C. Offering one-on-one counseling
D. Distributing written materials

Correct answer: A

Rationale: The most effective strategy in improving health literacy among patients is using clear and simple language in communication. Clear and simple language helps ensure that patients can easily understand health information, leading to better comprehension, decision-making, and health outcomes.
