A physician-validated, board-style question from the Active Transport QBank. Try it, then check the reasoning for every option.
A 49-year-old woman presents to her primary care physician for a routine health maintenance examination. She says that she is currently feeling well and has not noticed any acute changes in her health. She exercises 3 times a week and has tried to increase the amount of fruits and vegetables in her diet. She has smoked approximately 1 pack of cigarettes every 2 days for the last 20 years. Her last pap smear was performed 2 years ago, which was unremarkable. Her past medical history includes hypertension and type II diabetes. Her mother was diagnosed with breast cancer at 62 years of age. The patient is 5 ft 5 in (165.1 cm), weighs 185 lbs (84 kg), and has a BMI of 30.8 kg/m^2. Her blood pressure is 155/98 mmHg, pulse is 90/min, and respirations are 18/min. Physical examination is unremarkable. Lipid studies demonstrate an LDL cholesterol of 130 mg/dL and an HDL cholesterol of 42 mg/dL. Which of the following is the best next step in management?
-
A
Chest radiographyIncorrect. Chest radiography is not a screening test for lung cancer; low-dose CT is, but this patient (10 pack-years, age 49) does not yet meet USPSTF screening criteria (50-80 yo, >=20 pack-years, smoking within 15 years).
-
B
ColonoscopyIncorrect. Colonoscopy screening starts at age 45 per updated USPSTF guidelines, so it would be appropriate to discuss, but statin therapy more directly addresses her dominant cardiovascular risk profile and is the best next step.
-
C
MammogramIncorrect. Mammography is appropriate biennial screening for women 50-74, with shared decision-making for 40-49; at 49 it's reasonable to consider, but does not supersede statin therapy given her diabetes and cardiovascular risk burden.
-
D
Statin therapyCorrect. Statin therapy is indicated for this 49-year-old with type 2 diabetes (an automatic indication for moderate-intensity statin per ACC/AHA guidelines), hypertension, smoking, obesity, and elevated LDL — the best next step in management.
-
E
Low-dose CT of the chestIncorrect. Low-dose CT screens for lung cancer in adults aged 50-80 with a >=20 pack-year history; at age 49 with only 10 pack-years she does not yet meet USPSTF criteria.

Answer: D. Statin therapy is indicated for this 49-year-old woman based on her elevated 10-year ASCVD risk. She has multiple risk factors: hypertension (BP 155/98), type 2 diabetes, current smoking, obesity (BMI 30.8), and elevated LDL (130). The 2018 ACC/AHA cholesterol guidelines recommend moderate-intensity statin therapy for adults aged 40-75 with diabetes regardless of calculated ASCVD risk, and for any patient with a 10-year ASCVD risk >=7.5%. Her diabetes alone is sufficient indication.
Among the listed options, statin therapy directly addresses her dominant modifiable cardiovascular risk and the most lethal long-term threat (atherosclerotic cardiovascular disease). Mammography is recommended biennially for average-risk women aged 50-74 (USPSTF, with shared decision-making at 40-49) — she is 49 with a 62-year-old mother as her only family history of breast cancer, so she falls in shared-decision-making territory but is not the single best next step over statin therapy. Colonoscopy screening starts at 45 (per updated USPSTF) but a single 'best next step' here is statin given her cardiovascular risk profile. Chest radiography is not used for lung cancer screening (low-dose CT is, and she is below the age threshold of 50 even by USPSTF 2021 criteria, and she smokes only ~10 pack-years — below the 20-pack-year threshold for screening).
Clinical pearl: in a patient with multiple cardiovascular risk factors, statin therapy is high-yield primary prevention. The threshold for initiating statin should be addressed before less-impactful screening.
**Why each option:**
**A.** Chest radiography is not a screening test for lung cancer; low-dose CT is, but this patient (10 pack-years, age 49) does not yet meet USPSTF screening criteria (50-80 yo, >=20 pack-years, smoking within 15 years).
**B.** Colonoscopy screening starts at age 45 per updated USPSTF guidelines, so it would be appropriate to discuss, but statin therapy more directly addresses her dominant cardiovascular risk profile and is the best next step.
**C.** Mammography is appropriate biennial screening for women 50-74, with shared decision-making for 40-49; at 49 it's reasonable to consider, but does not supersede statin therapy given her diabetes and cardiovascular risk burden.
**D.** Statin therapy is indicated for this 49-year-old with type 2 diabetes (an automatic indication for moderate-intensity statin per ACC/AHA guidelines), hypertension, smoking, obesity, and elevated LDL — the best next step in management.
