This question tests understanding of preventive care and screening in primary care (USMLE Step 3). Preventive care involves applying evidence-based guidelines to recommend appropriate screenings and lifestyle modifications. In this vignette, the 50-year-old man has cardiovascular risk factors and no recent lipid testing, the recommended step is ordering a fasting lipid profile for ASCVD risk, aligning with ACC-AHA guidelines. Choice A is correct because it matches ACC-AHA recommendations for lipid screening in adults with risk factors to assess 10-year ASCVD risk. Choice B is incorrect because it suggests coronary CT angiography, which is not routinely recommended for primary prevention screening without symptoms. For teaching, emphasize the importance of staying updated with guidelines, identifying patient-specific risk factors, and prioritizing screenings that provide the greatest benefit. Encourage students to practice applying guidelines in varied scenarios to build confidence in clinical decision-making.

The Advisory Committee on Immunization Practices (ACIP) recommends the recombinant zoster vaccine (Shingrix) for all immunocompetent adults aged 50 and older, including those on low-dose immunosuppressive therapy such as methotrexate (≤0.4 mg/kg/week). The recombinant vaccine is not a live virus and is safe and effective in this population. The live attenuated vaccine would be contraindicated.

Choice A is correct because it matches USPSTF recommendations for screening adults aged 35-70 who are overweight or obese. Choice C is incorrect because it suggests no screening until symptoms, ignoring asymptomatic detection benefits. For teaching, emphasize the importance of staying updated with guidelines, identifying patient-specific risk factors, and prioritizing screenings that provide the greatest benefit. Encourage students to practice applying guidelines in varied scenarios to build confidence in clinical decision-making.

This question tests understanding of preventive care and screening in primary care (USMLE Step 3). Preventive care involves applying evidence-based guidelines to recommend appropriate screenings and lifestyle modifications. In this vignette, the 25-year-old woman with multiple partners has no prior HIV test, the recommended screening is one-time HIV Ag/Ab test, aligning with USPSTF guidelines. Choice A is correct because it matches USPSTF recommendations for screening all adults aged 15-65 at least once. Choice D is incorrect because it suggests no screening unless symptomatic, ignoring routine recommendations. For teaching, emphasize the importance of staying updated with guidelines, identifying patient-specific risk factors, and prioritizing screenings that provide the greatest benefit. Encourage students to practice applying guidelines in varied scenarios to build confidence in clinical decision-making.

This question tests understanding of preventive care and screening in primary care (USMLE Step 3). Preventive care involves applying evidence-based guidelines to recommend appropriate screenings and lifestyle modifications. In this vignette, the 10-year-old boy has BMI at 95th percentile with excessive screen time and soda intake, the prioritized modification is increasing daily physical activity and reducing screen time, aligning with AAP guidelines. Choice A is correct because it matches AAP recommendations for at least 60 minutes of activity daily and limiting screen time to reduce obesity risk. Choice D is incorrect because it suggests restricting all dietary fat, which is not balanced or recommended. For teaching, emphasize the importance of staying updated with guidelines, identifying patient-specific risk factors, and prioritizing screenings that provide the greatest benefit. Encourage students to practice applying guidelines in varied scenarios to build confidence in clinical decision-making.

This question tests understanding of preventive care and screening in primary care (USMLE Step 3). Preventive care involves applying evidence-based guidelines to recommend appropriate screenings and lifestyle modifications. In this vignette, the 70-year-old woman has no prior bone density testing, the recommended screening is DXA scan for osteoporosis, aligning with USPSTF guidelines. Choice A is correct because it matches USPSTF recommendations for osteoporosis screening in women aged 65 and older. Choice B is incorrect because it suggests whole-body CT, which is not indicated for fracture risk assessment. For teaching, emphasize the importance of staying updated with guidelines, identifying patient-specific risk factors, and prioritizing screenings that provide the greatest benefit. Encourage students to practice applying guidelines in varied scenarios to build confidence in clinical decision-making.

This question tests understanding of preventive care and screening in primary care (USMLE Step 3). Preventive care involves applying evidence-based guidelines to recommend appropriate screenings and lifestyle modifications. In this vignette, the 25-year-old woman wants age-based infectious disease screening, the recommended test is one-time hepatitis C antibody screening, aligning with USPSTF guidelines. Choice A is correct because it matches USPSTF recommendations for one-time screening in adults aged 18-79. Choice D is incorrect because it suggests no screening until age 50, ignoring the broad age range. For teaching, emphasize the importance of staying updated with guidelines, identifying patient-specific risk factors, and prioritizing screenings that provide the greatest benefit. Encourage students to practice applying guidelines in varied scenarios to build confidence in clinical decision-making.

This question tests understanding of preventive care and screening in primary care (USMLE Step 3). Preventive care involves applying evidence-based guidelines to recommend appropriate screenings and lifestyle modifications. In this vignette, the 25-year-old sexually active woman has no prior HPV vaccination, the most important vaccine is HPV vaccine series initiation, aligning with ACIP guidelines. Choice A is correct because it matches ACIP recommendations for HPV vaccination up to age 26 in those not previously vaccinated. Choice B is incorrect because it suggests zoster vaccine, which is recommended starting at age 50. For teaching, emphasize the importance of staying updated with guidelines, identifying patient-specific risk factors, and prioritizing screenings that provide the greatest benefit. Encourage students to practice applying guidelines in varied scenarios to build confidence in clinical decision-making.

This question tests understanding of preventive care and screening in primary care (USMLE Step 3). Preventive care involves applying evidence-based guidelines to recommend appropriate screenings and lifestyle modifications. In this vignette, the 25-year-old woman has no prior cervical screening, the most appropriate measure is cervical cytology every 3 years, aligning with USPSTF guidelines. Choice A is correct because it matches USPSTF recommendations for cytology every 3 years from ages 21-29. Choice D is incorrect because it suggests no screening until age 30, but screening starts at 21. For teaching, emphasize the importance of staying updated with guidelines, identifying patient-specific risk factors, and prioritizing screenings that provide the greatest benefit. Encourage students to practice applying guidelines in varied scenarios to build confidence in clinical decision-making.

Patients with inflammatory bowel disease (IBD) are at increased risk for colorectal cancer and require surveillance, not average-risk screening. For patients with left-sided colitis or pancolitis, surveillance colonoscopy should begin 8-10 years after the onset of symptoms. This patient, with a 12-year history, is overdue. The procedure involves taking multiple random biopsies throughout the colon to look for dysplasia.
