Lifestyle Choices and Self-Care: Practice Questions & Explanations

Tobacco cessation is the single most impactful modifiable health behavior change for most smokers.

Evidence-based approach: the 2008 USPHS Clinical Practice Guideline (updated) recommends COMBINATION of pharmacotherapy plus behavioral counseling as the most effective approach.

Pharmacotherapy options: (1) NICOTINE REPLACEMENT THERAPY (NRT) — patches, gum, lozenge, inhaler, nasal spray; reduces withdrawal symptoms; multiple forms can be combined (e.g., patch for baseline + gum for cravings); available OTC and prescription; (2) VARENICLINE (Chantix) — prescription; partial nicotinic agonist; blocks nicotine's rewarding effects; most effective single pharmacotherapy; monitor for neuropsychiatric side effects; (3) BUPROPION (Zyban/Wellbutrin) — prescription antidepressant with nicotine receptor effects; can be used alone or combined with NRT.

Behavioral counseling: individual or group; motivational interviewing; quit-smoking programs; quit lines (1-800-QUIT-NOW national helpline — free). THE 5 A's FRAMEWORK for brief intervention: ASK (about tobacco use at every visit); ADVISE (urge to quit in a clear, personalized, strong way); ASSESS (readiness to quit); ASSIST (offer pharmacotherapy, counseling, referral); ARRANGE (follow-up to check on progress). E-CIGARETTES are not FDA-approved cessation devices and evidence for their effectiveness as cessation tools is insufficient; they carry their own health risks. Simply reducing cigarette count ('cutting down') without a quit plan usually doesn't lead to lasting cessation.

Pn role: ask about tobacco use at every visit; advise to quit; provide brief counseling; refer to cessation resources; acknowledge that quit attempts are often required multiple times before success.

The U.S. Department of Health and Human Services PHYSICAL ACTIVITY GUIDELINES FOR AMERICANS (2nd edition) recommends for adults:

Aerobic activity: at least 150-300 minutes per week of moderate-intensity activity (like brisk walking, casual biking, water aerobics) OR 75-150 minutes per week of vigorous-intensity activity (like running, swimming laps, aerobic dance) OR an equivalent combination. Additional health benefits occur with more than 300 minutes.

Muscle-strengthening: activities of moderate or greater intensity involving all major muscle groups, 2 or more days per week (resistance training, body-weight exercises, heavy gardening).

Sitting less: any physical activity, even just reducing sitting time, has health benefits. CHILDREN (6-17): 60 minutes or more of moderate-to-vigorous activity per day; include vigorous intensity and muscle/bone-strengthening activities on at least 3 days/week.

Older adults: same recommendations as adults + add balance activities to prevent falls; 'some is better than none' is emphasized. HEALTH BENEFITS OF REGULAR PHYSICAL ACTIVITY: reduced risk of heart disease, stroke, type 2 diabetes, some cancers; weight management; improved bone and muscle health; improved mental health (reduces depression, anxiety); improved sleep; reduced risk of falls in older adults.

Nursing role: assess current activity levels; provide individualized guidance; help identify realistic ways to increase activity; reinforce that ANY activity is better than none — even breaking up long sitting periods with short walks; connect to community resources (walking programs, gym, senior center fitness).

MODERATE ALCOHOL USE — per NIAAA and USDA Dietary Guidelines for Americans: up to 1 standard drink per day for women; up to 2 standard drinks per day for men. A STANDARD DRINK = 14 grams of pure alcohol = 12 oz regular beer (5% ABV); 5 oz wine (12% ABV); 1.5 oz distilled spirits (40% ABV).

Note: the 2020-2025 Dietary Guidelines note that people who do not drink should not start for any perceived health benefit; even moderate drinking carries cancer risk (particularly breast cancer).

Binge drinking: 4+ drinks for women or 5+ drinks for men in about 2 hours, raising blood alcohol to ≥0.08 g/dL.

Heavy drinking: more than 4 drinks any day or 14 per week for men; more than 3 any day or 7 per week for women.

Health risks of heavy drinking: liver disease (fatty liver, alcoholic hepatitis, cirrhosis); pancreatitis; certain cancers (mouth, throat, esophagus, liver, colon, breast); cardiomyopathy; hypertension; peripheral neuropathy; Wernicke-Korsakoff syndrome (thiamine deficiency from poor nutrition); sexual dysfunction; depression and anxiety; addiction (alcohol use disorder).

Alcohol and pregnancy: NO amount of alcohol is known to be safe during pregnancy; alcohol is a teratogen causing Fetal Alcohol Spectrum Disorders (FASD), including fetal alcohol syndrome (FAS) — characterized by facial abnormalities, growth restriction, and neurodevelopmental problems.

Alcohol and sleep: alcohol may help fall asleep but disrupts REM sleep, resulting in poor sleep quality and daytime fatigue.

Alcohol and medications: many drug-alcohol interactions; particularly dangerous with: CNS depressants (benzodiazepines, opioids, sleeping pills), metronidazole, metformin, acetaminophen (hepatotoxicity risk). CAGE QUESTIONNAIRE and AUDIT are brief screening tools for problematic drinking.

BLOOD GLUCOSE TARGETS for adults with diabetes are established by the American Diabetes Association (ADA) in annual Standards of Medical Care in Diabetes. For most NON-PREGNANT ADULTS with diabetes: PREPRANDIAL (before meals): 80-130 mg/dL; POSTPRANDIAL (2 hours after the start of a meal): less than 180 mg/dL; A1c: less than 7% for most non-pregnant adults.

Individualized targets: more stringent (lower) for: younger patients with long life expectancy, no significant cardiovascular disease, short duration of diabetes, no hypoglycemia history; less stringent (higher) for: elderly patients, history of severe hypoglycemia, advanced complications, limited life expectancy, extensive comorbidities. HYPOGLYCEMIA (low blood sugar): less than 70 mg/dL; symptomatic: shakiness, diaphoresis, pallor, confusion, palpitations, hunger.

Treatment: RULE OF 15 — give 15 grams of fast-acting carbohydrates (4 oz juice, 4 oz regular soda, glucose tablets), recheck in 15 minutes; if still below 70, repeat; if unconscious or NPO, glucagon or IV dextrose. HYPERGLYCEMIA symptoms: polyuria, polydipsia, polyphagia, fatigue, blurred vision; acute crises: DKA (type 1, sometimes type 2) and HHS (type 2).

Self-monitoring: teach clients how to use glucometer; proper technique (clean finger, lancet, test strip); documentation; when to call provider.

Disease management: medication adherence (oral agents, insulin), diet (consistent carbohydrate intake with attention to glycemic index), physical activity (lowers blood glucose), stress management (stress hormones raise blood glucose), regular provider follow-up, foot care, annual eye and renal exams.

HYPERTENSION DIETARY MANAGEMENT evidence supports sodium reduction and the DASH (Dietary Approaches to Stop Hypertension) pattern as primary dietary interventions.

Sodium: Sodium causes water retention, increasing blood volume and blood pressure; the current recommendation is <2,300 mg/day for most adults, and the JNC guideline and AHA recommend <1,500 mg/day for those with hypertension; most Americans consume 3,400 mg/day — primarily from processed foods, restaurant meals, and canned goods.

Dash diet components: High: fruits and vegetables (8-10 servings/day); whole grains; low-fat dairy; nuts, seeds, legumes; lean poultry and fish; Low: red meat; sweets and sugar-sweetened beverages; saturated fats; sodium.

Evidence: The DASH diet reduces systolic BP by 8-14 mmHg — comparable to starting a single antihypertensive medication; sodium reduction by 1,000 mg/day reduces systolic BP by approximately 5-6 mmHg.

Additional lifestyle measures: Weight loss (each kg lost reduces BP ~1 mmHg); aerobic exercise (150+ min/week reduces BP 5-8 mmHg); moderate alcohol (<1 drink/day women, <2/day men); smoking cessation.

Pn teaching: Use MyPlate; read nutrition labels for sodium (aim <600 mg per serving for pre-packaged foods); choose fresh over canned; rinse canned foods; minimize restaurant and fast food; cook at home with herbs and spices instead of salt.

Skin cancer prevention: Skin cancer is the most common cancer in the US — over 5 million cases annually.

Prevention teaching:

Sunscreen: SPF 30 or higher; reapply every 2 hours (not just once in the morning); broad-spectrum (UVA + UVB protection); apply 15-30 minutes before sun exposure; don't forget ears, neck, back of hands.

Protective clothing: Long sleeves, hat with brim; tightly woven fabric; UV-protective clothing.

Shade: Peak UV hours are 10 AM to 4 PM.

Tanning beds: Increase melanoma risk by 75% when used before age 35.

Self-examination: Monthly — know the ABCDEs of melanoma: Asymmetry, Border irregularity, Color variation, Diameter >6mm, Evolution (change).

Dispelling myths: All skin tones can develop skin cancer; darker-skinned people have better (but not complete) UV protection; tanning is skin damage.

Warfarin and vitamin k: Warfarin works by blocking Vitamin K-dependent clotting factors (II, VII, IX, X).

Diet teaching: DO NOT abruptly increase vitamin K-rich foods (leafy greens — kale, spinach, collards, broccoli): this will decrease INR (more clotting, less anticoagulation — risk of clot); DO NOT abruptly eliminate vitamin K foods: this will increase INR (less clotting, more anticoagulation — bleeding risk); CONSISTENT intake is the goal — if you eat spinach twice a week, keep eating it twice a week. This is a key teaching distinction: patients often think they must eliminate all vitamin K, but the instruction is CONSISTENCY, not elimination. Other warfarin interactions: alcohol increases INR; cranberry juice increases INR; many medications interact. Monitor INR regularly; report unusual bruising or bleeding.

CARDIAC RISK REDUCTION AFTER MI — PRIORITY ORDER:

Smoking cessation: Smoking is one of the strongest modifiable risk factors for CAD — doubles the risk; cessation reduces recurrent MI risk by up to 50% within 1 year. This is the highest priority single lifestyle intervention.

Medication adherence: Aspirin, beta-blocker, statin, and ACE inhibitor/ARB are standard post-MI therapy — adherence is critical.

Diet: Heart-healthy diet (Mediterranean or DASH); reduce saturated and trans fats, sodium, added sugars; increase fruits, vegetables, whole grains, fish.

Physical activity: Cardiac rehabilitation programme; gradual return to activity; exercise reduces recurrence risk.

Stress management: Chronic stress is an independent risk factor.

Teaching priority: Smoking cessation is the answer to 'highest priority modification' — the others are also important but the magnitude of benefit from cessation is greatest.

IRON TYPES — HEME vs NON-HEME: Heme iron (from meat, poultry, fish): absorbed at 15-35% efficiency regardless of other foods; best dietary source. Non-heme iron (from plants, fortified foods): absorbed at 2-20%; absorption enhanced by vitamin C and inhibited by calcium, tannins (tea/coffee), and phytates. For iron deficiency anaemia education: recommend lean red meat, dark poultry meat, organ meats (highest heme iron); for vegetarians, combine non-heme iron sources with vitamin C (lemon juice, bell peppers, tomatoes) to maximise absorption. Also teach: avoid tea/coffee with iron-rich meals; cook in cast iron pans (leaches iron into food).

Aapd recommendation: First dental visit by age 1 or within 6 months of the first tooth eruption.

Why early: Dental caries (cavities) is the most common chronic childhood disease; early dental visits establish preventive care habits, identify early caries risk, provide fluoride varnish application, and educate parents about baby bottle tooth decay (putting infants to sleep with bottles of juice or milk); dentist assesses eruption patterns and jaw development. LPN/nursing role: educate parents at 6-9 month well-child visits about the first dental appointment recommendation. Early dental care prevents the pain, infection, and costs of untreated early childhood caries.

OSHA noise standards: Action Level: 85 dB time-weighted average over 8 hours — triggers hearing conservation programme (audiometric testing, hearing protection training, noise monitoring); Permissible Exposure Limit (PEL): 90 dB TWA 8 hours; at higher decibels, permitted exposure time decreases (95 dB → 4 hours max, 100 dB → 2 hours max, 115 dB → 15 minutes max).

Hearing loss: Noise-induced hearing loss is permanent and cumulative — damage is irreversible. Hearing protection (earplugs, earmuffs) is required when: working at or above 90 dB for 8 hours; exposure exceeds the time-limited threshold at higher levels. Engineering controls (reducing noise at source) are preferred over personal protective equipment.

PHQ-9 (Patient Health Questionnaire-9): 9 questions about depressive symptoms over the past 2 weeks; each scored 0-3 (not at all to nearly every day);

Scores: 0-4 none/minimal; 5-9 mild; 10-14 moderate; 15-19 moderately severe; 20-27 severe.

Validated: Multiple clinical settings, populations, languages; recommended by USPSTF for routine screening in adults.

Screening is recommended: USPSTF recommends depression screening for general adult population including pregnant and postpartum women; PHQ-2 (first 2 questions of PHQ-9) is used as ultra-brief screen — if positive, proceed to full PHQ-9; C-SSRS screens specifically for suicidal ideation, not depression broadly; Hamilton and BDI are clinician-administered or research-focused, less used in routine primary care.

SUICIDE RISK BY DEMOGRAPHIC (CDC data): Overall highest rate: men (4× higher than women); By age and race: White men have the highest rates across most age groups; Elderly white males 75+ have the highest absolute rate of any demographic group;

Risk factors: Social isolation; recent loss (spouse, independence); chronic illness or pain; access to lethal means (firearms); alcohol use; depression (often unrecognised and undertreated in older men who see help-seeking as weakness).

Protective factors: Social connectedness; religious affiliation; reason for living (grandchildren); engagement with healthcare.

Veterans: Also at elevated risk (20 veteran suicides per day) but not the highest-rate demographic as a whole; firearm access is a specific risk factor in this population.

LPN role: Depression screening at every encounter with high-risk populations; involve social work; assess for means access.

To help PREVENT OSTEOPOROSIS, recommend ADEQUATE CALCIUM and VITAMIN D intake (vitamin D aids calcium absorption) plus WEIGHT-BEARING EXERCISE (walking, resistance training stimulate bone density). NCLEX-PN health promotion/nutrition. Other measures: avoid smoking and excessive alcohol; fall prevention. Calcium sources: dairy, leafy greens, fortified foods. OLDER ADULTS and POSTMENOPAUSAL WOMEN are at higher risk (declining estrogen reduces bone density). Avoiding dairy or protein would worsen bone/overall health. Promoting calcium, vitamin D, and weight-bearing activity to maintain bone health is a tested health-promotion concept, especially for older adults.

Effective health teaching involves assessing the client's readiness to learn and current understanding, using clear, plain language at the client's level, breaking information into manageable pieces, and confirming comprehension — for example, by asking the client to restate or demonstrate the information (the teach-back method). Using jargon, overwhelming the client, or discouraging questions undermines learning. Tailoring teaching to the client and verifying understanding are core principles of client education and health promotion. Understanding these teaching principles is standard content. (This reflects general principles; verify against current NCLEX prep materials.)

Prevention is commonly described at three levels. Primary prevention aims to prevent disease before it occurs (e.g., immunization, healthy lifestyle, education). Secondary prevention aims to detect and treat disease early (e.g., screening tests). Tertiary prevention aims to manage established disease to limit complications and restore function (e.g., rehabilitation, ongoing management of a chronic condition). Recognizing the three levels of prevention — and being able to classify examples — is a foundational health-promotion concept. Understanding this framework helps the nurse identify the goal of various interventions. (This reflects a standard framework; verify against current NCLEX prep materials.)

General healthy-lifestyle teaching includes encouraging balanced nutrition, regular and appropriate physical activity, adequate sleep, stress management, and avoidance of tobacco and excessive alcohol — always tailored to the individual's needs, abilities, and any medical conditions. The nurse promotes sustainable, healthy behaviors rather than extreme or harmful measures (like skipping meals) and supports, not discourages, preventive care. Understanding broad, individualized healthy-lifestyle principles is a standard health-promotion concept. (This reflects general principles; any specific dietary or activity targets for a given client should be individualized and verified against current guidance and NCLEX prep materials.)

When teaching a psychomotor self-care skill, an effective general principle is to demonstrate the skill, then have the client perform a return demonstration so the nurse can confirm they can do it safely and correctly, providing feedback and reinforcement. Telling the client once, using only verbal explanation without practice, or discouraging self-care are less effective and can compromise safety. Return demonstration verifies competence and builds the client's confidence for self-care at home. Understanding this teaching principle is standard health-promotion content. (This reflects general principles; verify against current NCLEX prep materials.)
