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.

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.)
