Lifestyle Choices and Disease Prevention: Practice Questions & Explanations

Comprehensive lifestyle teaching addresses major modifiable risk factors for chronic disease. (1) Nutrition: balanced diet emphasizing fruits, vegetables, whole grains, lean protein, healthy fats; limit added sugars, refined carbs, sodium, saturated/trans fats; Mediterranean or DASH diets show strong evidence; portion control. (2) Physical activity: WHO/CDC recommend at least 150 minutes moderate-intensity OR 75 minutes vigorous-intensity aerobic activity per week, PLUS muscle-strengthening 2+ days/week. Any activity beats sedentary; sitting >8 hours daily is a risk factor. (3) Tobacco: avoid all forms (cigarettes, vaping, smokeless tobacco, secondhand smoke); cessation counseling and pharmacotherapy when ready; tobacco causes major morbidity and mortality. (4) Alcohol: limit to ≤1 drink/day for women, ≤2 for men (or less); abstinence preferred during pregnancy and for some medical conditions; no safe level for cancer risk. (5) Sleep: 7-9 hours/night for adults; sleep hygiene practices; address sleep apnea and insomnia. (6) Stress management: mindfulness, exercise, social connection, hobbies, therapy when needed. (7) Social connections: strong social relationships reduce all-cause mortality. (8) Preventive care: annual physical (or every 1-3 years per age), screenings, immunizations, dental care. (9) Sun protection: sunscreen, protective clothing, shade. (10) Safety: seatbelts, helmets, fall prevention, gun safety. These factors prevent leading causes of death: heart disease, cancer, stroke, COPD, diabetes complications, accidents.

Colorectal cancer screening guidelines updated by ACS in 2018 and USPSTF in 2021 to lower age from 50 to 45 due to increased CRC incidence in younger adults. Screening options for average-risk adults age 45-75: (1) Colonoscopy every 10 years — gold standard; can identify and remove polyps in one procedure; requires prep and sedation; (2) Fecal Immunochemical Test (FIT) annually — non-invasive stool test for blood; requires colonoscopy if positive; (3) FIT-DNA (Cologuard) every 1-3 years — stool test detecting DNA markers and blood; requires colonoscopy if positive; (4) Sigmoidoscopy every 5 years — examines only lower colon; (5) CT Colonography (virtual colonoscopy) every 5 years — imaging study; requires colonoscopy if abnormal; (6) Sigmoidoscopy plus annual FIT. Choice depends on patient preference, ability to undergo prep/sedation, cost, insurance, family history. Higher-risk individuals (family history, inflammatory bowel disease, certain genetic syndromes) need earlier and more frequent screening. After 75: individualized decision; ACS suggests through age 85 may benefit. Patient education: prep is the worst part of colonoscopy for most; many adults avoid screening due to anxiety; nurses can normalize the procedure and address concerns. Stool-based tests offer alternatives for those who decline colonoscopy.

Exercise initiation guidance for previously sedentary clients: (1) Medical clearance — recommended for adults 45+ starting vigorous exercise, those with chronic conditions, or those with cardiovascular risk factors; ECG stress test for some; (2) Start gradually — '10% rule' for runners (don't increase weekly mileage by more than 10%); applies generally to intensity, frequency, duration; (3) Warm up — 5-10 minutes of low-intensity activity to raise heart rate, increase blood flow to muscles; (4) Cool down — 5-10 minutes of decreasing intensity; stretching during cool-down; (5) FITT principle for prescription: Frequency (how often), Intensity (how hard), Time (how long), Type (what kind); (6) Variety — combine aerobic (walking, swimming, cycling), strength (resistance training 2+ days/week), flexibility (stretching, yoga), balance (especially for older adults); (7) Hydration — water before, during, and after exercise; (8) Nutrition — adequate fuel and recovery foods; (9) Equipment — proper shoes, supportive clothing, helmets and safety gear; (10) Listen to the body — distinguish discomfort (normal) from sharp pain (stop); rest days important; (11) Signs to stop exercise: chest pain, severe shortness of breath, dizziness, irregular heartbeat, severe joint pain. Realistic goal-setting: 150 minutes moderate or 75 minutes vigorous aerobic exercise per week, plus strength training 2x/week — but starting with any activity is beneficial. Enjoyable activities promote adherence. Tracking progress motivates continuation.

Breast cancer screening guidelines vary by organization but generally include: (1) Average-risk women: USPSTF 2024 update recommends biennial screening mammograms starting at age 40 (lowered from 50 in 2024 update); ACS recommends annual screening starting at 45, with option to start at 40, then biennial after 54; ACR recommends annual starting at 40. (2) Higher-risk women (family history, prior breast cancer, BRCA mutations, chest radiation): earlier screening, MRI in addition to mammography. (3) Stopping: USPSTF says insufficient evidence after 75; many recommendations consider life expectancy. Clinical Breast Exam (CBE): performed by clinicians during physicals; effectiveness debated; ACS removed routine CBE recommendation in 2015. Breast self-exam (BSE) — historically taught as routine practice, but evidence does not support reducing mortality; current recommendation is 'breast awareness' — knowing what is normal and reporting changes (lumps, dimpling, nipple discharge, skin changes). Concerns about mammography: false positives (additional imaging, biopsies, anxiety); overdiagnosis (detecting cancers that would not have become symptomatic); radiation exposure (very low dose). Benefits: reduced breast cancer mortality; earlier detection allows less aggressive treatment. The trade-offs and individual risk profile inform screening decisions. Shared decision-making between provider and patient is increasingly emphasized. Nurses help patients understand screening options and address barriers.

Sodium and hypertension: dietary sodium contributes to elevated blood pressure by increasing fluid retention and vascular resistance. The American Heart Association recommends less than 2,300 mg sodium/day for most adults; less than 1,500 mg for those with hypertension, heart failure, or kidney disease. HIDDEN SODIUM SOURCES are the major challenge — most Americans get 70-75% of sodium from PROCESSED and RESTAURANT FOODS, not from the salt shaker.

Highest-sodium processed foods: DELI MEATS (ham, turkey, salami: 600-1,500 mg per 2 oz serving); CANNED SOUPS (700-1,200 mg per cup); FROZEN DINNERS (800-2,300 mg per meal); BREAD/ROLLS (100-200 mg per slice — adds up quickly); CONDIMENTS (soy sauce: 900 mg per tablespoon; ketchup: 150 mg per tablespoon); CHEESE (processed cheese: 400 mg per oz); PIZZA; FAST FOOD. FRESH FOODS are naturally low sodium: fresh fruits, vegetables, plain meats, eggs, dry beans.

Teaching tips: read Nutrition Facts labels — look for sodium per serving; choose low-sodium or no-salt-added versions of canned goods; rinse canned beans and vegetables (reduces sodium 30-40%); use herbs, spices, lemon, vinegar instead of salt for flavoring; limit restaurant meals; be aware that 'reduced sodium' still may be high. The DASH diet (Dietary Approaches to Stop Hypertension) is the gold-standard dietary pattern for blood pressure: high in fruits, vegetables, whole grains, low-fat dairy, lean protein; low in red meat, sweets, saturated fat, sodium.

Fasting glucose interpretation: Normal: 70-99 mg/dL; Prediabetes: 100-125 mg/dL (impaired fasting glucose); Diabetes: 126 mg/dL or above on two separate occasions. The client's 112 mg/dL falls squarely in the PREDIABETES range.

Nursing implications: Education on lifestyle modifications: 5-7% weight loss if overweight; 150 minutes/week moderate-intensity aerobic exercise; reduced intake of refined carbohydrates, saturated fats, and processed foods; the Diabetes Prevention Program (DPP) showed that lifestyle intervention reduced progression to diabetes by 58% in high-risk individuals; consider referral to a structured lifestyle program; repeat HbA1c or fasting glucose in 1 year.

Levels of prevention in health:

Primary: Prevent the condition from occurring — reducing risk factors, health promotion activities (smoking cessation, stress management, social connectedness).

Secondary: Early detection and prompt treatment — screening tools (PHQ-9 for depression, CAGE for alcohol use, Columbia Suicide Severity Rating Scale), identifying at-risk individuals before full criteria are met, initiating treatment early to prevent worsening.

Tertiary: Managing established disease to minimize disability and restore function — mental health rehabilitation, supported employment, community mental health services for those with chronic serious mental illness.

Secondary prevention examples: Universal depression screening at primary care visits; school-based mental health screening programs; screening high-risk groups (postpartum women, chronic pain patients, cancer patients); early cognitive intervention programs for at-risk youth.

DASH DIET (Dietary Approaches to Stop Hypertension): Developed specifically to reduce blood pressure.

Key components: Fruits: 4-5 servings/day; Vegetables: 4-5 servings/day; Whole grains: 6-8 servings/day; Low-fat dairy: 2-3 servings/day; Lean meats, poultry, fish: ≤6 oz/day; Nuts, seeds, legumes: 4-5 servings/week; Fats/oils: 2-3 servings/day; Sweets: ≤5 per week.

Sodium: Standard DASH = <2,300 mg/day; Lower-sodium DASH = <1,500 mg/day (recommended for HTN, diabetes, CKD, age 51+, Black adults).

Evidence: Reduces systolic BP by 8-14 mmHg; comparable to single antihypertensive medication.

Nursing education: Focus on what to ADD (produce, whole grains) before restricting — positive framing improves adherence.

Who definition of mental health: 'A state of well-being in which every individual realises his or her own potential, can cope with the normal stresses of life, can work productively and fruitfully, and is able to contribute to his or her community.'.

Key concepts: Mental health is a POSITIVE STATE, not just the absence of illness; it exists on a CONTINUUM — not binary; people can have GOOD mental health WHILE managing a mental illness (e.g., a person with well-controlled bipolar disorder who is thriving at work).

Determinants: Genetics, brain biology, life experiences, family history, social connections, access to resources — all contribute.

Nursing role: Reduce stigma by framing mental health positively; screen for risk factors; provide early intervention education; promote resilience factors (social support, coping skills, physical activity, sleep hygiene, purpose/meaning).

PRIMARY PREVENTION of cardiovascular disease (preventing it before it develops) focuses on LIFESTYLE: REGULAR PHYSICAL ACTIVITY (e.g., ~150 min/week moderate); a HEART-HEALTHY DIET (fruits, vegetables, whole grains, lean protein; limit saturated/trans fats, sodium, added sugars); SMOKING CESSATION; maintaining a HEALTHY WEIGHT; limiting alcohol; managing stress. NCLEX-RN health promotion.

Prevention levels: PRIMARY (prevent disease — lifestyle, immunizations); SECONDARY (early detection — screening); TERTIARY (manage existing disease, prevent complications — rehab). For a client without disease, lifestyle modification is primary prevention; medications would be later if needed. Promoting heart-healthy lifestyle for primary prevention is a key tested concept.

Good general practice in health-behavior change is to collaborate with the client to set goals that are realistic, individualized, and measurable, and that the client is genuinely motivated to pursue — increasing the likelihood of success and sustained change. Setting goals for the client without input reduces ownership, extreme goals can discourage or harm, and avoiding goals provides no direction. Client-centered, collaborative goal-setting is a cornerstone of effective health promotion and behavior change. Understanding this collaborative approach is a standard concept. (This reflects general principles; verify against current NCLEX prep materials.)

Culturally competent health promotion means respecting the client's cultural beliefs, values, and practices and incorporating them into care and teaching when it is safe and feasible, while avoiding stereotyping (recognizing that individuals within any culture differ). Applying a single standard approach to everyone or ignoring cultural factors reduces effectiveness and can harm trust. Cultural competence improves communication, engagement, and outcomes. Understanding the principle of individualized, culturally respectful care is a standard health-promotion concept. (This reflects general principles; verify against current NCLEX prep materials.)

A general health-promotion principle is that regular, appropriate physical activity supports overall physical and mental health for most adults, and it should be individualized to the person's health status, abilities, and any medical considerations. Activity benefits people across the lifespan, not just competitive athletes, and is not something to be discouraged with age (older adults benefit from appropriate activity too, with individualization). The nurse encourages and helps tailor activity safely. Understanding the general benefit and individualization of physical activity is a standard concept. (Specific activity recommendations should be individualized and verified against current authoritative guidance and NCLEX prep materials.)

Community-level health promotion addresses the health needs of populations and groups — through public education, improving access to resources and care, and programs and policies that support healthy behaviors and environments — in addition to caring for individuals. Focusing only on individuals, ignoring community needs, or withholding public health information would limit the broader impact of health promotion. Nurses contribute to community health through education and advocacy. Understanding that health promotion operates at both individual and community levels is a standard concept. (This reflects general principles; verify against current NCLEX prep materials.)
