Saudi Prometric Nursing Community and Public Health Nursing 2 — Questions and Answers
Question 1: The nurse is calculating the infant mortality rate (IMR). Which formula is correct?
- (Deaths of infants <1 year / Live births) × 1,000 (Correct answer)
- (Deaths of infants <1 year / Total population) × 1,000
- (Deaths of infants <5 years / Live births) × 1,000
- (Deaths of infants <1 year / Total deaths) × 1,000
Correct answer: (Deaths of infants <1 year / Live births) × 1,000
The infant mortality rate is the number of deaths of infants under 1 year per 1,000 live births in a given year. It is a key indicator of a country's health system quality, maternal health, and socioeconomic conditions.
Question 2: A nurse is conducting a health assessment of a community. Which data source provides population-level mortality data?
- Vital statistics records (death certificates) (Correct answer)
- Hospital discharge summaries
- Outpatient clinic encounter records
- Behavioral risk factor surveys
Correct answer: Vital statistics records (death certificates)
Vital statistics (birth and death certificates) are the primary source of population-level mortality data, including cause of death, age, sex, and geography. They form the basis for calculating mortality rates and trends.
Question 3: Which type of immunity is conferred by childhood immunization programs?
- Active acquired immunity (Correct answer)
- Passive natural immunity
- Passive acquired immunity
- Innate immunity
Correct answer: Active acquired immunity
Vaccines stimulate the immune system to produce antibodies against specific antigens, creating active acquired immunity. This is 'acquired' because it is gained through exposure and 'active' because the immune system actively responds. Passive immunity involves receiving pre-formed antibodies.
Question 4: The nurse is implementing a health promotion program based on the Health Belief Model. Which component of this model most strongly predicts whether an individual will take preventive action?
- Perceived barriers to taking action (Correct answer)
- Perceived susceptibility to disease
- Perceived severity of disease
- Cues to action
Correct answer: Perceived barriers to taking action
Research on the Health Belief Model shows perceived barriers are the strongest predictor of non-action — if the person perceives too many obstacles (cost, inconvenience, fear), they are unlikely to act regardless of how susceptible or severe they believe the disease to be.
Question 5: A school nurse notes an outbreak of head lice (pediculosis capitis) in an elementary school. Which public health measure is most evidence-based?
- Treat affected children with pediculicide; no-nit policies are not recommended (Correct answer)
- Send all children home until all cases are treated
- Fumigate the school
- Screen all children daily for 4 weeks
Correct answer: Treat affected children with pediculicide; no-nit policies are not recommended
Current evidence-based guidelines (CDC, AAP) recommend treating affected children with pediculicide shampoo and do NOT support 'no-nit' policies (sending children home for nit presence), as nits alone do not indicate active infestation and cause unnecessary school absence.
Question 6: A public health nurse is working on a food safety inspection following a Salmonella outbreak linked to a restaurant. Which food handling practice most likely caused the outbreak?
- Cross-contamination between raw poultry and ready-to-eat foods (Correct answer)
- Inadequate refrigerator temperature (5°C vs. recommended ≤4°C)
- Failure to label food with expiration dates
- Using commercial rather than homemade mayonnaise
Correct answer: Cross-contamination between raw poultry and ready-to-eat foods
Cross-contamination between raw poultry (a major Salmonella reservoir) and ready-to-eat foods (salads, bread, cooked foods) is the most common cause of Salmonella outbreaks. This occurs through shared cutting boards, utensils, or poor hand hygiene.
The nurse is calculating the infant mortality rate (IMR).
