Difficulty: MediumPreventive Care and Screening

A physician is reviewing the electronic health record of a male patient born in 1961 ahead of an upcoming wellness visit. The current year is 2026. The patient has a past medical history of mild persistent asthma and hypertension. He currently smokes 1.5 packs of cigarettes daily and has done so for the past 30 years. Medical records indicate that a screening colonoscopy performed 6 years ago revealed no polyps or abnormalities. Hepatitis C screening was negative 3 years ago. His immunization record documents the administration of the 20-valent pneumococcal conjugate vaccine (PCV20) at age 63 and a tetanus, diphtheria, and acellular pertussis (Tdap) booster 4 years ago. He has no history of receiving any formulation of the shingles vaccine. He has never undergone vascular or pulmonary imaging.

Which of the following preventive interventions are currently indicated for this patient? (Select all that apply)

  1. One-time screening with ultrasonography of the abdominal aortaAnswer
  2. Annual screening with low-dose computed tomography of the chestAnswer
  3. Administration of the recombinant zoster vaccineAnswer
  4. D
    Screening colonoscopy
  5. E
    Administration of the 20-valent pneumococcal conjugate vaccine
  6. F
    Routine screening with a prostate-specific antigen test

Answer

The currently indicated interventions are a one-time ultrasound of the abdominal aorta, annual low-dose computed tomography of the chest, and the recombinant zoster vaccine.
The patient is exactly 65 years old and has a 45 pack-year smoking history. This combination makes him eligible for several critical preventive measures. First, the USPSTF recommends a one-time screening for an abdominal aortic aneurysm (AAA) with ultrasonography in men aged 65 to 75 years who have ever smoked. Second, annual lung cancer screening with low-dose computed tomography (LDCT) is recommended for adults aged 50 to 80 years with a 20 pack-year or greater smoking history who currently smoke or quit within the past 15 years. Finally, the two-dose recombinant zoster vaccine series is indicated for all adults aged 50 years and older, regardless of prior herpes zoster infection or vaccination status.

Step-by-Step Solution

1
Calculate the patient's current age based on the provided temporal context.
The patient was born in 1961, and the current year is 2026, making him exactly 65 years old.
Preventive screening guidelines are strictly tied to specific age milestones.
2
Identify the patient's key demographic and lifestyle risk factors.
The patient is a 65-year-old male with a 45 pack-year smoking history (1.5 packs/day × 30 years) who is a current smoker.
Smoking history dictates specific vascular and pulmonary screening requirements.
3
Apply current USPSTF and ACIP guidelines to the patient's profile and past medical history.
At age 65 with a smoking history, he requires abdominal aortic aneurysm screening and ongoing lung cancer screening. As an adult over 50, he requires the zoster vaccine. His prior normal colonoscopy and prior PCV20 dose mean those interventions are not currently due.
To ensure guideline-concordant care without over-testing or over-vaccinating.
