Community and Public Health Nursing Flashcards

During a community health assessment in a rural region of Saudi Arabia, a nurse identifies that the under-5 mortality rate is 18 per 1,000 live births. According to the Saudi Vision 2030 Health Sector Transformation Program targets, which action should the community health nurse PRIORITIZE to have the greatest impact on reducing this indicator?

Answer: Expanding immunization outreach to nomadic and semi-nomadic populations not covered by fixed health centers

Reaching underserved nomadic and semi-nomadic populations through mobile immunization and outreach services directly addresses the primary drivers of under-5 mortality in rural Saudi Arabia — vaccine-preventable diseases and limited preventive care access. Saudi Vision 2030's health transformation emphasizes equity and reaching underserved populations through primary health care strengthening. Adding specialists or tertiary units addresses downstream curative care rather than upstream prevention where mortality reduction is greatest.

A community health nurse in Saudi Arabia is calculating the attack rate during a suspected foodborne outbreak at a wedding celebration. Of 240 guests who attended, 180 ate the kabsa dish, and 60 did not. Among those who ate kabsa, 72 developed gastroenteritis. Among those who did not eat kabsa, 6 developed gastroenteritis. What is the food-specific attack rate for kabsa?

Answer: 40%

The food-specific attack rate is calculated as (number ill among those who ate the food ÷ total who ate the food) × 100. Here: 72 ÷ 180 × 100 = 40%. This is distinct from the overall attack rate (78/240 = 32.5%) or the rate among non-exposed (6/60 = 10%). The food-specific attack rate is used in outbreak investigations to implicate specific food vehicles.

A Saudi community health nurse is conducting an epidemiological investigation of tuberculosis (TB) in a densely populated urban district in Riyadh. The nurse identifies an index case — a 35-year-old male worker in a shared labor accommodation. According to the Saudi Ministry of Health TB Control Program guidelines, which contact investigation strategy should be applied FIRST?

Answer: Concentric circle approach starting with household and close workplace contacts before expanding to social contacts

The Saudi MOH TB Control Program follows WHO-aligned contact investigation using the concentric circle (stone-in-pond) approach: prioritizing highest-risk close contacts (household members and prolonged workplace contacts) first, then expanding outward based on infectiousness of the index case. Universal geographic screening is resource-intensive and not evidence-based as a first step. Symptom-based restriction would miss latent TB infection, and universal chest X-ray without risk stratification is not the initial recommended approach.

In the context of Saudi Arabia's Maternity and Child Health (MCH) services, a community health nurse is evaluating the effectiveness of antenatal care (ANC) in a primary health care center. Which indicator BEST reflects the quality — rather than quantity — of ANC provided?

Answer: Proportion of pregnant women who received iron supplementation and had blood pressure measured at each visit

Quality of ANC is measured by whether evidence-based clinical interventions (such as iron supplementation and blood pressure monitoring at each visit) were actually delivered — these reflect process quality. The percentage attending four or more visits and early registration are access/utilization indicators reflecting quantity and timeliness but not whether the visits provided the required clinical content. Total visit counts are volume metrics, not quality measures.

A community health nurse working at a primary health care center in Saudi Arabia is planning a health education intervention for type 2 diabetes prevention targeting middle-aged Saudi men with prediabetes. Using the PRECEDE-PROCEED model, which factor would be classified as a REINFORCING factor?

Answer: Positive feedback from the patient's physician about lifestyle improvements during follow-up visits

In the PRECEDE-PROCEED model, reinforcing factors are rewards, feedback, or social support that follow a behavior and increase the likelihood of its continuation — such as physician praise and encouragement during follow-up. The patient's belief in prevention is a predisposing factor (attitudes/beliefs that motivate behavior). Availability of food options is an enabling factor (resources that facilitate behavior). Knowledge is also a predisposing factor. This distinction is critical for designing community interventions.

A Saudi community health nurse is analyzing vital statistics data for a district and notes the following: crude birth rate = 22 per 1,000 population; crude death rate = 6 per 1,000 population; in-migration rate = 8 per 1,000; out-migration rate = 3 per 1,000. What is the net population growth rate per 1,000 population for this district?

Answer: 21 per 1,000

Net population growth rate = (Crude Birth Rate − Crude Death Rate) + (In-migration Rate − Out-migration Rate). Natural increase = 22 − 6 = 16 per 1,000. Net migration = 8 − 3 = 5 per 1,000. Total = 16 + 5 = 21 per 1,000. This formula is essential in community health planning in Saudi Arabia, where expatriate in-migration significantly affects population growth rates and health service demand projections.
