Key Takeaways

  • Primary prevention aims to prevent disease before it occurs (immunizations, health education)
  • Secondary prevention focuses on early detection through screening (mammograms, colonoscopies)
  • Tertiary prevention prevents complications in those already diagnosed (diabetes management)
  • Age-appropriate screening recommendations guide preventive care for different populations
  • The LPN/LVN educates patients about recommended screenings and healthy behaviors

Health Screening and Disease Prevention

Preventive care reduces the burden of disease and improves quality of life. The LPN/LVN contributes to prevention efforts through patient education, screening assistance, and health promotion activities.

Levels of Prevention

LevelGoalExamples
PrimaryPrevent disease before it occursImmunizations, seat belts, nutrition education
SecondaryEarly detection of existing diseaseMammograms, blood pressure screening, colonoscopy
TertiaryPrevent complications, restore functionCardiac rehab, diabetes management, physical therapy

Immunization Schedules

Childhood Immunizations (Key Vaccines):

VaccineWhen Given
Hepatitis BBirth, 1-2 months, 6-18 months

Td/TdapTdap once, then Td every 10 years
Shingles (Zoster)Two doses at age 50+
PneumococcalAge 65+ or high-risk conditions
COVID-19Per current CDC recommendations

Cancer Screening Recommendations

CancerScreening TestRecommendation
BreastMammogramWomen 50-74: every 2 years; earlier if high risk
CervicalPap test/HPVWomen 21-65: every 3 years (Pap) or 5 years (Pap + HPV)
ColorectalColonoscopy, stool testsAge 45-75: colonoscopy every 10 years or alternatives
LungLow-dose CTAge 50-80 with 20+ pack-year smoking history
ProstatePSA, DREShared decision-making starting at age 50

Cardiovascular Screening

TestFrequencyPurpose
Blood pressureAt every visit, annually minimumDetect hypertension
Lipid panelEvery 4-6 years (age 20+)Assess cardiovascular risk
Blood glucoseEvery 3 years (age 45+)Detect diabetes/prediabetes
BMI calculationAt every visitAssess weight status

Pediatric Screening

ScreeningWhenPurpose
Newborn screeningBirthMetabolic and genetic conditions
HearingBirth, at well visitsDetect hearing loss
VisionAt well visits, age 3-5Detect visual problems
LeadAge 1-2 in high-risk areasDetect lead exposure
DevelopmentalAt well visitsIdentify developmental delays
Autism18 and 24 monthsEarly detection of autism spectrum

Sexually Transmitted Infection (STI) Screening

ScreeningWhoFrequency
Chlamydia/GonorrheaSexually active women under 25Annually
HIVAll adults 13-64At least once; more often if high risk
SyphilisAt-risk populationsBased on risk assessment
Hepatitis CAll adults 18-79At least once

Risk Assessment

Cardiovascular Risk Factors:

  • Hypertension
  • Diabetes
  • Hyperlipidemia
  • Smoking
  • Obesity
  • Family history
  • Physical inactivity

Cancer Risk Factors:

  • Tobacco use

Health Education Topics

TopicKey Teaching Points
Smoking cessationResources available, benefits of quitting, relapse prevention
NutritionBalanced diet, portion control, limiting processed foods
Physical activity150 minutes moderate activity weekly, benefits
Weight managementHealthy BMI, gradual weight loss if needed
Sun safetySunscreen, protective clothing, avoid peak hours
Alcohol useModerate consumption, risks of excess

The LPN/LVN Role in Prevention

ActivityExamples
EducationTeach about screening recommendations, healthy behaviors
AssistanceHelp with screening procedures, collect specimens
DocumentationRecord screening results, update health maintenance records
ReinforcementReinforce teaching by RN or provider
ReportingReport screening results and patient concerns

Barriers to Preventive Care

BarrierNursing Approach
Lack of knowledgeProvide education about recommendations
Financial concernsConnect with resources, community programs
Fear of resultsAddress concerns, emphasize benefits of early detection
Cultural beliefsRespect beliefs while providing information
Access issuesIdentify community screening events
