1. Which age group is most vulnerable to protein-energy malnutrition (PEM)?

A. Infants below 6 months
B. Children aged 1-4 years
C. Adolescents
D. Elderly

Correct answer: B

Rationale: Children aged 1-4 years are most vulnerable to protein-energy malnutrition (PEM) due to their rapid growth and development, increased nutritional requirements, and sometimes inadequate diets. This age group is particularly susceptible to malnutrition if they do not receive adequate protein and energy-rich foods to support their growth and development.

2. 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.

4. Which of the following conditions is a contraindication for breastfeeding?

A. Maternal HIV infection
B. Maternal diabetes
C. Maternal anemia
D. Maternal hypertension

Correct answer: A

Rationale: Maternal HIV infection is a contraindication for breastfeeding because it poses a risk of transmission to the infant. HIV can be transmitted through breast milk, putting the baby at risk of acquiring the infection. Therefore, it is recommended that mothers with HIV do not breastfeed to prevent the transmission of the virus to their infants.

A. Reduces the risk of postpartum depression
B. Increases the baby's risk of developing allergies
C. Provides complete nutrition for the first 6 months
D. Delays the return of menstrual periods

Correct answer: C

Rationale: The correct answer is C. Exclusive breastfeeding provides complete nutrition for the first 6 months of an infant's life. It is recommended by health experts as the ideal way to provide infants with the nutrients they need for healthy growth and development. Breast milk contains all the necessary nutrients in the right proportions, making it the perfect food for babies during the first half-year of life.
