Health Promotion and Maintenance 2 — Questions and Answers
Question 1: A nurse is providing anticipatory guidance to the parents of a 4-month-old infant. Which developmental milestone should the parents expect at this age?
- Walking with support
- Saying 'mama' or 'dada' with meaning
- Rolling from back to side (Correct answer)
- Using a pincer grasp
Correct answer: Rolling from back to side
At 4 months, infants typically can roll from their back to their side. Walking with support occurs around 9-12 months, meaningful words at 10-14 months, and pincer grasp develops around 9-10 months.
Anticipatory guidance helps parents understand normal developmental milestones so they can support their child's growth and identify potential developmental delays early. At 4 months, the infant's gross motor skills have advanced significantly since birth. Expected 4-month milestones include: rolling from back to side (and possibly tummy to back), holding head steady when supported upright, pushing up on arms when on tummy, tracking objects past midline, recognizing familiar faces, social smiling, cooing and beginning to babble, bringing hands to mouth, and showing interest in a rattle. Walking with support is a 9-12 month milestone. The pincer grasp (using thumb and index finger to pick up small objects) develops around 9-10 months. Saying 'mama' or 'dada' with meaning is a 10-14 month milestone. Using single words with meaning is typically a 12-month milestone. When parents report that their child is not meeting expected milestones, the nurse should perform a thorough developmental screening using a validated tool such as the Denver Developmental Screening Test II (DDST-II) and refer to the pediatrician or developmental specialist for further evaluation. Early intervention is most effective when delays are identified promptly.
Question 2: A nurse is providing nutrition education to a pregnant client in the first trimester. Which nutrient deficiency is most likely to cause neural tube defects in the developing fetus?
- Iron
- Calcium
- Folic acid (Correct answer)
- Vitamin D
Correct answer: Folic acid
Folic acid (folate) deficiency during the periconceptional period and early pregnancy is strongly associated with neural tube defects such as spina bifida and anencephaly. Women of childbearing age should consume 400-800 mcg of folic acid daily.
Neural tube defects (NTDs), including spina bifida and anencephaly, result from failure of the neural tube to close properly during the third and fourth weeks of embryonic development — often before a woman even knows she is pregnant. Folic acid (vitamin B9) plays a critical role in DNA synthesis and cell division required for proper neural tube closure. The Centers for Disease Control and Prevention (CDC) and the American College of Obstetricians and Gynecologists (ACOG) recommend that all women of childbearing age consume 400 mcg (0.4 mg) of folic acid daily through diet and supplements. Women with a history of a prior pregnancy affected by NTD are advised to take 4 mg daily, starting at least 1 month before conception. Folic acid is found naturally in leafy green vegetables, legumes, citrus fruits, and fortified grain products. Because the neural tube closes by day 28 of gestation, supplementation must begin before conception to be effective — many women do not begin prenatal vitamins until after a missed period. Iron deficiency in pregnancy is associated with anemia. Calcium deficiency can affect fetal bone development. Vitamin D is important for calcium absorption and bone health but is not specifically linked to NTDs. Folic acid has the strongest evidence-based link to neural tube defect prevention.
Question 3: A nurse is providing health education to a 45-year-old female client with no risk factors. Which cancer screening test should the nurse recommend at this time?
- Annual mammogram (Correct answer)
- Annual low-dose CT scan of the chest
- Colonoscopy within the next 5 years
- Annual Pap smear with HPV co-test
Correct answer: Annual mammogram
The American Cancer Society recommends that women with average risk begin annual mammograms at age 40-45. At age 45, annual mammography is the appropriate screening recommendation for breast cancer.
Cancer screening guidelines are a key component of health promotion nursing education. Recommending appropriate screenings based on age, sex, and risk factors helps detect cancers early when treatment is most effective. For a 45-year-old average-risk woman, current recommendations include: annual mammogram (ACS recommends starting at 45; USPSTF recommends beginning at 40-50 depending on individual preference and discussion with provider). Colorectal cancer screening begins at age 45 for average-risk individuals (updated guideline from ACS and USPSTF), but a colonoscopy is typically done every 10 years — not every 5 years. The option for colonoscopy within 5 years may refer to surveillance colonoscopy after polyp removal, which would not apply to a no-risk-factor client. Low-dose CT chest screening is recommended annually for adults aged 50-80 who have a 20 pack-year smoking history and currently smoke or quit within the past 15 years — not average-risk nonsmokers. Pap smears for average-risk women aged 30-65 are recommended every 3 years (Pap alone) or every 5 years (Pap + HPV co-test). Annual Pap smears are no longer recommended for average-risk women. So for a 45-year-old, annual mammogram is the most appropriate current screening recommendation.
Question 4: A nurse is teaching a client about risk factors for type 2 diabetes. Which modifiable risk factor should the nurse emphasize most strongly?
- Family history of type 2 diabetes
- Age over 45 years
- Overweight or obesity (BMI ≥ 25) (Correct answer)
- History of gestational diabetes
Correct answer: Overweight or obesity (BMI ≥ 25)
Overweight and obesity are the most important modifiable risk factors for type 2 diabetes. Excess body fat, particularly visceral fat, causes insulin resistance. Weight loss through diet and exercise can significantly reduce or delay the onset of type 2 diabetes.
Type 2 diabetes is largely preventable through lifestyle modification, particularly in high-risk individuals. Understanding the distinction between modifiable and non-modifiable risk factors guides health promotion counseling. Modifiable risk factors for type 2 diabetes include: overweight/obesity (especially central adiposity), physical inactivity, poor dietary patterns (high in refined carbohydrates and saturated fats), hypertension, dyslipidemia, and cigarette smoking. Of these, obesity is the single strongest modifiable risk factor — approximately 90% of individuals with type 2 diabetes are overweight or obese. Non-modifiable risk factors include: family history of diabetes, age ≥45 years, race/ethnicity (African American, Hispanic, Native American, Asian American), history of gestational diabetes, and polycystic ovary syndrome (PCOS). These cannot be changed, but knowing about them helps identify who needs more intensive screening. The Diabetes Prevention Program (DPP) clinical trial demonstrated that modest weight loss (5-7% of body weight) combined with 150 minutes of moderate physical activity per week reduced the incidence of type 2 diabetes by 58% in high-risk individuals. This evidence forms the basis for lifestyle intervention counseling in health promotion settings.
Question 5: A nurse is counseling a client who asks about the best methods to reduce cardiovascular disease risk. Which lifestyle modification has the strongest evidence for reducing cardiovascular risk?
- Taking a daily low-dose aspirin
- Eliminating all dietary fat intake
- Engaging in regular aerobic exercise (Correct answer)
- Consuming red wine in moderation
Correct answer: Engaging in regular aerobic exercise
Regular aerobic exercise has the strongest evidence base for reducing cardiovascular disease risk. It lowers blood pressure, improves lipid profiles, reduces body weight, and improves insulin sensitivity — all major cardiovascular risk factors.
Cardiovascular disease (CVD) is the leading cause of death in the United States, and the vast majority of risk is attributable to modifiable lifestyle factors. Regular physical activity is one of the most powerful preventive interventions available. Aerobic exercise (at least 150 minutes of moderate-intensity activity per week, such as brisk walking, cycling, or swimming) has been shown to: lower systolic blood pressure by 4-9 mmHg, reduce LDL cholesterol, raise HDL cholesterol, reduce triglycerides, improve insulin sensitivity, promote weight loss, reduce inflammation, and decrease resting heart rate — all of which directly reduce cardiovascular risk. Dietary fat modification is important, but eliminating all fat is not recommended or evidence-based. Healthy unsaturated fats (olive oil, avocados, nuts) are cardioprotective, while saturated and trans fats should be limited. Red wine consumption has been associated with cardiovascular benefit in observational studies, but alcohol carries health risks and the American Heart Association does not recommend drinking for cardiovascular benefit. Daily low-dose aspirin is no longer recommended for primary prevention of CVD in adults without known CVD disease due to bleeding risks that outweigh benefits (2022 USPSTF update). Exercise remains the cornerstone of both primary and secondary CVD prevention counseling.
Question 6: A nurse is providing immunization education to the parents of a healthy 12-month-old child. Which vaccine is recommended at this visit?
- Hepatitis B (HepB) first dose
- Measles, mumps, and rubella (MMR) first dose (Correct answer)
- Inactivated poliovirus (IPV) fourth dose
- DTaP fifth dose
Correct answer: Measles, mumps, and rubella (MMR) first dose
The MMR (measles, mumps, rubella) vaccine first dose is recommended at 12-15 months of age according to the CDC immunization schedule. The HepB series begins at birth, IPV fourth dose is at 4-6 years, and DTaP fifth dose is at 4-6 years.
The Advisory Committee on Immunization Practices (ACIP) publishes the recommended immunization schedule for children, which is updated annually. Nurses must be familiar with the schedule to provide accurate anticipatory guidance and identify vaccine-eligible clients. At the 12-15 month visit, the following vaccines are recommended: MMR (first dose), Varicella (VAR, first dose), Hepatitis A (HepA, first of two doses given 6 months apart), and PCV15 or PCV20 (pneumococcal conjugate, fourth dose). The MMR and varicella vaccines can also be given as the combined MMRV vaccine. The HepB series is started at birth, with subsequent doses at 1-2 months and 6-18 months — so by 12 months, the series is typically complete. The DTaP series is given at 2, 4, 6 months, then 15-18 months (fourth dose), and the fifth dose at 4-6 years. The IPV series fourth dose is given at 4-6 years. Parents may have concerns about vaccine safety, particularly regarding the MMR vaccine and autism — a claim thoroughly disproven by multiple large studies. The nurse should address these concerns with evidence-based information, validate the parent's desire to protect their child, and emphasize the significant risks of vaccine-preventable diseases.
