Difficulty: EasyClinical Preventive Services and Screening

Match each patient presentation with the most appropriate primary preventive screening recommendation based on current United States Preventive Services Task Force (USPSTF) guidelines.

  • 58-year-old man with a 30 pack-year smoking history who currently smokesAnnual screening with low-dose computed tomography (LDCT)
  • 45-year-old asymptomatic woman with no significant family history of cancerBiennial screening with mammography
  • 30-year-old pregnant woman presenting for her initial prenatal visit at 9 weeks gestationScreening for HIV, syphilis, and hepatitis B virus infection
  • 22-year-old sexually active, nonpregnant woman who is completely asymptomaticScreening for Chlamydia trachomatis and Neisseria gonorrhoeae

Answer

The 58-year-old heavy smoker matches with annual LDCT for lung cancer. The 45-year-old woman matches with biennial mammography for breast cancer. The pregnant woman matches with initial prenatal screening for HIV, syphilis, and HBV. The 22-year-old sexually active woman matches with routine screening for chlamydia and gonorrhea.
Each patient presentation strictly maps to a specific Level A or B recommendation by the USPSTF: LDCT for adults 50-80 with a 20+ pack-year history, biennial mammograms for average-risk women aged 40-74, a standard infectious disease panel (HIV, syphilis, HBV) for early pregnancy, and routine chlamydia/gonorrhea screening for sexually active women under 25.

Step-by-Step Solution

1
Identify the key demographic features and clinical risk factors for each patient.
Patient 1 is an older adult with a significant smoking history. Patient 2 is a middle-aged woman of average risk. Patient 3 is in the first trimester of pregnancy. Patient 4 is a sexually active female under age 25.
Preventive guidelines are strictly determined by age, sex, pregnancy status, and specific risk behaviors or histories.
2
Correlate each patient profile with the corresponding Grade A or Grade B recommendation from the USPSTF.
Patient 1 meets criteria for LDCT lung screening; Patient 2 meets criteria for breast cancer screening; Patient 3 requires standard prenatal infectious disease screening; Patient 4 requires routine STI screening for young women.
Matching each demographic explicitly to its evidence-based guideline ensures appropriate preventive care and avoids unnecessary testing.
