Question

Difficulty: Very hardPreventive Care and Screening

Match each patient's clinical vignette with the most appropriate next step in preventive screening or disease surveillance based on current evidence-based guidelines.

  • A 37-year-old woman who received mantle field radiation therapy for Hodgkin lymphoma at age 22. She currently has no palpable breast masses or clinical symptoms.Initiate annual screening with both magnetic resonance imaging (MRI) and mammography.
  • A 58-year-old postmenopausal woman with severe rheumatoid arthritis who has been maintained on 10 mg10\text{ mg} of prednisone daily for three years. She has never undergone bone density testing.Schedule a dual-energy x-ray absorptiometry (DXA) scan now, prior to the standard age threshold.
  • A 28-year-old woman at 10 weeks of gestation during her first pregnancy. She reports no high-risk behaviors and has no prior history of sexually transmitted infections.Perform screening for hepatitis C virus (HCV) infection as part of her initial prenatal laboratory panel.
  • A 34-year-old man who sustained a deep, soil-contaminated puncture wound to his foot. His last documented tetanus, diphtheria, and acellular pertussis (Tdap) booster was administered exactly 6 years ago.Administer a tetanus toxoid-containing booster today, as the appropriate timeframe has elapsed for this specific injury type.

Answer

Match the high-risk and exception-based clinical vignettes to their corresponding guideline-concordant screening and immunization recommendations.
Each vignette represents a specific exception to standard screening guidelines: mantle radiation necessitates early dual-modality breast screening; chronic steroids require early DXA testing; pregnancy mandates universal HCV screening regardless of behavior; and contaminated wounds shorten the required tetanus booster interval from 10 years to 5 years.

Step-by-Step Solution

1
Evaluate the breast cancer screening requirements for the 37-year-old woman with a history of mantle field radiation.
She requires immediate initiation of high-risk screening with both breast MRI and mammography.
Chest radiation prior to age 30 significantly elevates breast cancer risk, negating the standard age 40 or 50 screening onset.
2
Assess the indications for osteoporosis screening in the 58-year-old postmenopausal woman.
She should undergo a DXA scan now.
Chronic glucocorticoid therapy and severe rheumatoid arthritis are major risk factors that mandate early bone density screening before the standard age of 65.
3
Determine the necessary prenatal infectious disease screening for the 28-year-old pregnant woman without risk factors.
She must receive HCV screening alongside standard prenatal labs.
Guidelines have been updated to require universal HCV screening during every pregnancy to identify vertical transmission risks and coordinate postpartum treatment.
4
Calculate the tetanus prophylaxis timeframe for the 34-year-old man with a contaminated puncture wound.
He requires a tetanus booster today.
Because the wound is dirty and his last booster was 6 years ago (which is >5>5 years), the standard 10-year rule does not apply.

Key Concept
