Preventive Healthcare Basics Flashcards

Question 1

What does the term preventive healthcare mean in everyday practice?

Accepted Answer

Preventive healthcare is the set of services and activities aimed at keeping people healthy or stopping illness, injury, or disability before it starts or gets worse. It includes education, screening, immunization, and counseling about lifestyle. Its goal is to reduce the burden of disease over time for individuals and whole communities.

Question 2

What is the difference between a risk factor and a disease?

Accepted Answer

A risk factor is an attribute, exposure, or behavior that raises the likelihood that a person will develop a particular disease or condition. A disease is the condition itself. Many risk factors, such as smoking or physical inactivity, can be changed, which is why they are central targets of prevention efforts.

Question 3

What is a health promotion program, and how does it differ from prevention?

Accepted Answer

Health promotion is the process of enabling people to increase control over and improve their health, often through policy, environments, and education. Prevention is narrower, aiming to stop specific diseases or injuries from occurring or progressing. The two overlap, and many programs combine them, so they are often discussed together.

Question 4

Which role do social determinants of health play in preventive care?

Accepted Answer

Social determinants of health are the conditions in which people are born, grow, live, work, and age, such as income, housing, education, and access to food. These conditions shape health risks and opportunities. Preventive efforts that ignore them may reach only part of a population, so planners often address them alongside individual behavior.

Question 5

What is the purpose of a population health perspective?

Accepted Answer

A population health perspective looks at the distribution of health outcomes across a group, such as a town, employer, or patient panel, rather than focusing on one person. It asks which groups are most affected and which exposures are common. This view guides where prevention resources should go to have the greatest benefit.

Question 6

What does incidence measure, and how is it different from prevalence?

Accepted Answer

Incidence measures the number of new cases of a condition that develop in a defined population during a specified period. Prevalence measures the total number of existing cases at a given point in time, both new and ongoing. Prevention programs track incidence to judge whether fewer people are becoming affected, while prevalence helps planners estimate ongoing service needs.

Question 7

Why is a baseline measurement useful in a prevention program?

Accepted Answer

A baseline measurement is a record of conditions or behaviors taken before an intervention begins. It gives program staff a reference point, so later results can be compared against where things started. Without a baseline, it is difficult to tell whether changes came from the program or from other factors happening at the same time.

Question 8

What is a cohort, and why do prevention researchers study it?

Accepted Answer

A cohort is a group of people who share a defined characteristic or experience, such as entering a program at the same time. Researchers follow cohorts to see how exposures relate to later outcomes. This design helps show which factors may come before a health change, although it does not by itself prove cause.

Question 9

What are the three traditional levels of prevention?

Accepted Answer

The three traditional levels are primary, secondary, and tertiary prevention. Primary prevention aims to stop a condition from starting. Secondary prevention aims to detect it early and limit its progress. Tertiary prevention aims to reduce complications and disability in people who already have a condition.

Question 10

What is an example of primary prevention in a community setting?

Accepted Answer

A community campaign that promotes smoke-free public spaces is a useful example. It aims to lower exposure to secondhand smoke and reduce the chance that young people begin using tobacco, so it acts before any illness appears. This is primary prevention because it acts on causes rather than on existing illness.

Question 11

What is the goal of secondary prevention, and what is a common method?

Accepted Answer

The goal of secondary prevention is early detection of disease or risk so that intervention can happen before significant harm occurs. A common method is screening, which tests people who have no symptoms. Screening programs are judged by whether earlier detection leads to better outcomes, not just by how many people are tested.

Question 12

What is tertiary prevention, and how does it differ from curing a condition?

Accepted Answer

Tertiary prevention focuses on reducing the impact of an established condition, including complications, disability, and loss of function. It supports people in living as well as possible with a long-term problem. Curing a condition removes it entirely, which is not always possible, so tertiary prevention aims at limiting harm and improving quality of life.

Question 13

Why do prevention programs often focus on modifiable risk factors?

Accepted Answer

Modifiable risk factors are those a person or community can change, such as tobacco use, diet, physical activity, or alcohol consumption. Non-modifiable factors, such as age or family history, cannot be changed but can still help identify who may benefit from closer attention. Programs focus on modifiable factors because changing them can reduce future risk.

Question 14

What does the term primordial prevention mean in public health?

Accepted Answer

Primordial prevention aims to stop risk factors from ever emerging in a population, such as by shaping social norms, environments, and policies before harmful habits become common. It is sometimes described as a level that comes before primary prevention. This makes it a population-wide idea, linked to the broader aims of health promotion.

Question 15

How does the concept of a window of opportunity apply to prevention?

Accepted Answer

A window of opportunity is a period when an intervention is most likely to change the course of a health problem, such as before a risk behavior becomes established. Planners use this idea to time education, counseling, and outreach. Missing the window does not end prevention, but later efforts are often harder.

Question 16

Why is the concept of a levels framework useful, even though real activities often overlap?

Accepted Answer

A levels framework gives planners a shared vocabulary for describing what an activity is meant to achieve. It helps match resources to the stage at which a problem can best be addressed. Real programs often blur these lines, so the levels are guides rather than rigid boxes.

Question 17

What is a case-finding approach, and how does it differ from mass screening?

Accepted Answer

Case-finding means testing people who already visit a healthcare setting for another reason, such as a routine appointment. Mass screening targets an entire defined population, regardless of why people come in. Case-finding is usually more practical in routine care, while mass screening is used when a condition is common enough to justify broad outreach.

Question 18

What does it mean to say a test has high sensitivity?

Accepted Answer

High sensitivity means a screening test correctly identifies most people who truly have the condition being checked for. A test with high sensitivity misses fewer true cases. It says nothing, on its own, about how often the test wrongly flags people who do not have the condition, which is a separate measure called specificity.

Question 19

What is a false positive result in screening?

Accepted Answer

A false positive is a screening result that suggests a condition may be present when it is not. These results lead to follow-up testing and worry, so programs weigh them against the benefit of finding true cases. Every screening test produces some false positives, and their rate depends on the test and the population tested.

Question 20

What does specificity measure in a screening test?

Accepted Answer

Specificity measures how often a screening test correctly gives a negative result for people who do not have the condition. A test with high specificity produces fewer false positives. Like sensitivity, it describes the test itself and does not show how likely a given person is to have the condition.

Question 21

Why do screening guidelines specify an age range or eligibility criteria?

Accepted Answer

Eligibility criteria define who should be offered a screening test, based on factors such as age, sex, or risk level. Narrowing the target group helps programs focus on people who are most likely to benefit and reduces harms for those who are unlikely to. Guidelines are updated as evidence changes.

Question 22

What is the purpose of a screening program's follow-up pathway?

Accepted Answer

A follow-up pathway is the planned sequence of steps taken after a screening result, such as confirmatory testing, referral, and communication with the person screened. Programs need clear pathways so that abnormal results are not lost. A screening test without a defined follow-up path may add harm with little benefit.

Question 23

What are screening program quality indicators and why are they tracked?

Accepted Answer

Quality indicators are measurable items that show how well a screening program performs, such as the share of eligible people who are reached, the proportion of results followed up in a timely way, and how many results are recorded accurately. Tracking them lets managers spot gaps, compare sites, and improve processes over time.

Question 24

What is a screening registry and what does it do?

Accepted Answer

A screening registry is an organized database that records who is eligible for screening, when they were tested, and what the results and follow-up were. It helps programs send reminders, monitor coverage, and avoid people being missed. Good registries protect privacy and share only the information needed for each purpose.

Question 25

What is an immunization record and what key details does it contain?

Accepted Answer

An immunization record is a documented history of the immunizations a person has received. Key details usually include the name of the immunization, the date it was given, the administering provider or site, and identifying information for the person. Accurate records support continuity of care and show whether recommended immunizations are up to date.

Question 26

What is the difference between a personal record and an immunization information system?

Accepted Answer

A personal record is held by an individual or a single provider and shows the immunizations recorded there. An immunization information system is a centralized electronic database that collects records from many providers in a region. Linking the two helps reduce gaps when a person receives care in several places.

Question 27

What does it mean for a person to be up to date on immunizations?

Accepted Answer

Being up to date means a person has received all the immunizations recommended for their age, risk group, or circumstances at the time of review. The recommendations come from official public health guidance, which changes as evidence changes. Because the list varies by setting, staff should confirm the current guidance rather than rely on memory.

Question 28

What is vaccine hesitancy, and why do programs track it?

Accepted Answer

Vaccine hesitancy describes delay in accepting or refusing vaccines despite their availability. It is shaped by many factors, including trust, convenience, access, and information. Programs track it in surveys and clinic data to understand where outreach and education may help, rather than to label individuals.

Question 29

How do public health programs use coverage rates?

Accepted Answer

Coverage rate is the proportion of a target group that has received a particular immunization, usually calculated as the number vaccinated divided by the number eligible. Programs compare coverage across neighborhoods and age groups to find where protection is weaker. Coverage data guides outreach, staffing, and reminder efforts, and supports required reporting.

Question 30

What is herd immunity, and why does it depend on coverage?

Accepted Answer

Herd immunity, also called community immunity, is indirect protection that arises when enough people in a population are immune to a contagious disease that it has difficulty spreading. Protection for people who cannot be immunized depends on this effect. The threshold needed varies by disease and by how easily it spreads, so coverage targets differ.

Question 31

What is a cold chain and why does it matter for program administration?

Accepted Answer

A cold chain is the controlled system of storage and transport that keeps temperature-sensitive products within a required range from manufacture to use. Programs record temperature logs as part of their documentation, because gaps in the chain can make products unusable. Good records let staff show that products were handled correctly and identify problems quickly.

Question 32

What does an adverse event reporting system do?

Accepted Answer

An adverse event reporting system collects and reviews reports of unwanted or unexpected events that follow a vaccine, so that safety concerns can be detected and investigated. A report does not by itself show that the product caused the event. Such systems depend on reports from many sources.

Question 33

What are the basic food groups used in general nutrition education?

Accepted Answer

General nutrition education commonly groups foods into vegetables, fruits, grains, protein foods, and dairy or dairy alternatives. Many frameworks also emphasize healthy fats and limit added sugars, sodium, and highly processed items. Groupings differ by country and by framework, so learners should consult the guidance that applies where they work.

Question 34

What is energy balance, and how does it relate to body weight?

Accepted Answer

Energy balance is the relationship between energy taken in through food and drink and energy used by the body through metabolism and physical activity. When intake and use are roughly equal, body weight tends to stay stable. Sustained imbalance over time tends to change weight, though many other factors also influence body weight.

Question 35

What is a serving size, and why is it different from a portion?

Accepted Answer

A serving size is a standardized amount of food used as a reference on nutrition labels and in dietary guidance. A portion is the amount a person actually chooses to eat, which may be larger or smaller. Comparing portions with servings helps people judge how much they are consuming relative to recommendations.

Question 36

What does the term dietary fiber refer to in nutrition science?

Accepted Answer

Dietary fiber refers to carbohydrates and related plant components that the human digestive system does not fully break down into absorbable sugars. It is found mainly in whole grains, legumes, fruits, vegetables, and nuts. Nutrition guidance generally encourages higher fiber intake from these whole foods.

Question 37

How are population nutrition surveys used in prevention planning?

Accepted Answer

Population nutrition surveys collect information on what people eat and drink, often through structured questionnaires. Planners use the results to identify common gaps, such as low fruit and vegetable intake, and to track change over time. Survey findings guide policy and education, though they depend on accurate self-report and careful sampling.

Question 38

What is a healthy eating pattern, as opposed to a single nutrient focus?

Accepted Answer

A healthy eating pattern describes the overall mix of foods and drinks a person consumes across days and weeks. Public health guidance increasingly favors patterns over single nutrients, because foods are eaten in combination and their effects overlap. A pattern emphasizes variety, whole foods, and balance, rather than attempting to optimize one component in isolation.

Question 39

What is the purpose of a health impact assessment?

Accepted Answer

A health impact assessment is a structured process that estimates how a proposed policy, program, or project might affect the health of a population. It considers both positive and negative effects, including effects on housing, transport, and employment. Results are used to recommend changes before decisions are finalized, so health is considered early.

Question 40

What is the difference between an outcome measure and a process measure?

Accepted Answer

An outcome measure tracks a change in health or a result that matters to people, such as the rate of a condition. A process measure tracks whether planned activities happened, such as the share of eligible people offered a service. Both are useful, because process measures can show progress before outcomes change.
