1. Which of the following is an example of a live attenuated vaccine?

A. Hepatitis B vaccine
B. Inactivated polio vaccine
C. Measles, Mumps, Rubella (MMR) vaccine
D. Diphtheria, Tetanus, Pertussis (DPT) vaccine

Correct answer: C

Rationale: The Measles, Mumps, Rubella (MMR) vaccine is an example of a live attenuated vaccine because it contains weakened versions of the viruses that cause measles, mumps, and rubella. These weakened viruses can replicate in the body to stimulate an immune response without causing the diseases themselves.

2. RA 1054 is also known as the Occupational Health Act. Besides the number of employees, what other factor must be considered in determining the occupational health privileges to which the workers will be entitled?

A. Type of occupation: agriculture, commercial, industrial
B. Location of the workplace in relation to health facilities
C. Classification of the business enterprise based on net profit
D. Sex and age composition of employees

Correct answer: B

Rationale: According to R.A. 1054, the key factor to consider, apart from the number of employees, is the location of the workplace concerning health facilities. Specifically, an occupational nurse must be employed when there are 30 to 100 employees, and the workplace is more than 1 km away from the nearest health center. This ensures timely access to health services for employees in case of emergencies or health needs.

3. Which statistic best reflects the nutritional status of a population?

A. 1-4 year old age-specific mortality rate
B. Proportionate mortality rate
C. Infant mortality rate
D. Swaroop’s index

Correct answer: A

Rationale: The most appropriate statistic to reflect the nutritional status of a population is the 1-4 year old age-specific mortality rate. This age group is highly susceptible to the effects of malnutrition, so a population with poor nutritional status is likely to have a high 1-4 year old age-specific mortality rate, also known as child mortality rate.

4. What care is given to a woman within a month after the delivery of a baby?

A. Follow-up care
B. Maternity care
C. Puerperal care
D. Post-natal care

Correct answer: D

Rationale: Post-natal care is the care provided to a woman after childbirth, typically within the first month. It involves various aspects such as monitoring the mother's health, providing guidance on maternal nutrition, promoting breastfeeding, and educating on maternal and child care practices. This comprehensive care aims to ensure the well-being of both the mother and the newborn during the postpartum period.

5. Tertiary prevention is needed in which stage of the natural history of disease?

A. Pre-pathogenesis
B. Pathogenesis
C. Predromal
D. Terminal

Correct answer: D

Rationale: Tertiary prevention focuses on actions taken to prevent complications and further deterioration among individuals already diagnosed with a disease. It is implemented during the terminal stage of a disease when efforts are made to prevent disability, restore function, and improve quality of life. This stage is crucial for managing the disease's progression and enhancing the patient's well-being.
