Difficulty: HardPreventive Care and Screening

Match each patient clinical profile with the single most appropriate next step in preventive care and screening according to current clinical guidelines.

  • A 42-year-old man whose father was diagnosed with colon cancer at age 50. He has no chronic medical conditions, his adult vaccinations are up to date, and he has never undergone colorectal screening.Initiate colonoscopy screening immediately, with subsequent surveillance every 5 years.
  • A 58-year-old woman with a 35 pack-year smoking history who quit 10 years ago. Her immunizations are up to date and she had a normal screening colonoscopy at age 52.Perform an annual low-dose computed tomography (LDCT) of the chest.
  • A 28-year-old woman presenting for a routine visit, reporting a new male sexual partner. She has no chronic conditions. Her last Pap smear with human papillomavirus (HPV) cotesting at age 26 was normal.Screen for Chlamydia trachomatis and Neisseria gonorrhoeae using nucleic acid amplification testing.
  • A 50-year-old man with poorly controlled type 2 diabetes mellitus. He does not smoke and had a normal colonoscopy last month. He has never received a pneumococcal vaccination.Administer a single dose of the 20-valent pneumococcal conjugate vaccine (PCV20).

Answer

The 42-year-old man requires immediate colonoscopy repeated every 5 years; the 58-year-old former smoker requires annual LDCT; the 28-year-old woman requires STI screening; and the 50-year-old diabetic man requires the PCV20 vaccine.
Each match strictly aligns with USPSTF and ACIP recommendations. The man with early-onset family history of colon cancer requires a 5-year colonoscopy interval starting at age 40. The older former smoker falls within the 15-year cessation window for LDCT. The young woman with a new partner requires STI screening without disrupting her 5-year Pap/HPV interval. The diabetic man requires early pneumococcal vaccination due to his comorbid status.

Step-by-Step Solution

1
Analyze the 42-year-old man's family history of early-onset colorectal cancer.
Determine he meets criteria for high-risk screening (start at age 40, or 10 years before the first-degree relative's diagnosis at age 50).
Standard screening at age 45 every 10 years is insufficient for high-risk patients, making immediate colonoscopy with a 5-year interval the required step.
2
Evaluate the 58-year-old woman's smoking history against lung cancer screening criteria.
Determine she falls within the 50-80 age range, exceeds the 20 pack-year minimum, and is within the 15-year cessation window.
This qualifies her for annual LDCT screening to reduce lung cancer mortality.
3
Differentiate between cervical cancer screening guidelines and STI screening guidelines for the 28-year-old woman.
Determine her Pap/HPV cotest is valid for 5 years (due at age 31), but her new sexual partner necessitates NAAT for chlamydia and gonorrhea.
It is a common error to prematurely repeat a Pap smear for a new partner; STI screening is the appropriate targeted intervention.
4
Identify vaccination indications for the 50-year-old diabetic man.
Determine that his diabetes places him in a high-risk group requiring pneumococcal vaccination prior to the universal age cutoff of 65.
PCV20 is indicated for adults aged 19-64 with immunocompromising conditions, chronic organ disease, or diabetes.

Key Concept

Application of evidence-based preventive screening and vaccination guidelines based on patient age, precise family history, behavioral risk factors, and comorbidities.
