1. What procedure is performed prior to a blood transfusion to detect incompatibilities?

• A. Grouping and crossmatching
• B. Complete blood count
• C. D-dimer test
• D. Blood clotting test

Correct answer: A

Rationale: Grouping and crossmatching is the procedure performed prior to a blood transfusion to determine the blood type and identify any potential incompatibilities between the donor and recipient. This process involves testing the recipient's blood for ABO and Rh antigens and crossmatching it with the donor's blood to ensure compatibility and prevent adverse reactions during the transfusion. Complete blood count, D-dimer test, and blood clotting test are other laboratory tests that serve different purposes and are not specifically done to detect incompatibilities prior to blood transfusion.

2. What is the primary goal of public health?

• A. To achieve health equity
• B. To prevent disease and disability
• C. To prolong life
• D. To promote health

Correct answer: B

Rationale: The primary goal of public health is to prevent disease and disability by implementing measures to protect and improve the health of communities and populations. While achieving health equity, prolonging life, and promoting health are important aspects of public health, the central focus remains on preventing diseases and disabilities through various strategies such as vaccination programs, health education, and environmental regulations.

3. Which of the following is an example of a communicable disease?

• A. Diabetes
• B. Hypertension
• C. HIV/AIDS
• D. Cholera

Correct answer: D

Rationale: Cholera is caused by the bacterium Vibrio cholerae and is transmitted through contaminated water or food. It spreads rapidly in areas with poor sanitation and can lead to severe dehydration and even death if untreated. Unlike diabetes and hypertension, which are non-communicable diseases often influenced by lifestyle factors, HIV/AIDS and cholera are infectious diseases that can be transmitted from person to person.

4. Which sign or reflex is used to diagnose meningitis?

• A. Homan's sign
• B. Brudzinski
• C. Startle
• D. Anterior drawer

Correct answer: B

Rationale: Brudzinski sign is a physical exam finding used to diagnose meningitis. It is elicited by flexing the patient's neck, resulting in involuntary flexion of the hips and knees. This maneuver indicates meningeal irritation, a common feature in meningitis. Homan's sign is used to assess for deep vein thrombosis, Startle is a reflex response to sudden stimuli, and the Anterior drawer test is used to diagnose ligamentous instability in the knee.

5. Which action is an example of secondary prevention in public health?

• A. Administering vaccines to prevent disease
• B. Providing treatment for chronic diseases
• C. Screening for early signs of disease
• D. Offering health education workshops

Correct answer: C

Rationale: The correct answer is screening for early signs of disease (Choice C). Secondary prevention focuses on early detection and treatment of diseases to prevent their progression. By screening for early signs of disease, individuals can receive timely interventions, leading to better health outcomes. Administering vaccines (Choice A) falls under primary prevention by preventing the occurrence of diseases. Providing treatment for chronic diseases (Choice B) is part of tertiary prevention, which focuses on managing and reducing complications of established diseases. Offering health education workshops (Choice D) can be part of primary prevention by promoting healthy behaviors to prevent diseases.
