Zorluk: ZorClinical Preventive Services and Screening

A 66-year-old woman is evaluated at an ambulatory clinic as a new patient. She recently lost her health insurance and has not received comprehensive medical care for the past two years. She has a history of essential hypertension, for which she takes amlodipine. She underwent natural menopause at age 52. During the review of systems, the patient mentions that two months ago she experienced three days of light vaginal bleeding, which she attributed to "normal changes of aging." The bleeding has not recurred. She has a 45 pack-year smoking history and currently smokes one pack of cigarettes daily. Her father died of a ruptured abdominal aortic aneurysm at age 75. A review of her records shows a normal screening colonoscopy and negative cervical human papillomavirus (HPV) testing performed at age 64. She recently received a normal screening mammography and an updated influenza vaccine at a local health fair. Vital signs show a blood pressure of 136/84 mm Hg, heart rate of 76/min, and body mass index (BMI) of 29 kg/m 2^2. Physical examination, including a pelvic examination, is unremarkable with no active bleeding. Which of the following sets of diagnostic and screening tests is the most appropriate next step in the management of this patient?

  1. Endometrial biopsy, low-dose computed tomography of the chest, and dual-energy x-ray absorptiometryCevap
  2. B
    Reassurance for vaginal bleeding, low-dose computed tomography of the chest, and dual-energy x-ray absorptiometry
  3. C
    Endometrial biopsy, chest radiograph, and dual-energy x-ray absorptiometry
  4. D
    Endometrial biopsy, low-dose computed tomography of the chest, and abdominal duplex ultrasonography
  5. E
    Transvaginal ultrasonography in 6 months, low-dose computed tomography of the chest, and abdominal duplex ultrasonography

Cevap

Endometrial biopsy, low-dose computed tomography of the chest, and dual-energy x-ray absorptiometry
The correct combination includes diagnostic evaluation for postmenopausal bleeding (endometrial biopsy) alongside appropriate age- and risk-based preventive screening (low-dose computed tomography of the chest and dual-energy x-ray absorptiometry). Postmenopausal bleeding is highly suspicious for endometrial cancer and requires prompt tissue sampling. Regarding preventive care, this 66-year-old female with a 45 pack-year smoking history meets the USPSTF criteria for both annual lung cancer screening via low-dose chest CT and one-time osteoporosis screening via a DEXA scan. She does not require a colonoscopy or mammogram as those are up to date.

Adım Adım Çözüm

1
Analyze the patient's acute or subacute symptom (vaginal bleeding).
The patient has a history of postmenopausal bleeding (PMB).
PMB is a high-risk indicator for endometrial carcinoma. It requires immediate diagnostic evaluation, typically with an endometrial biopsy, which supersedes purely preventive care.
2
Evaluate the patient's need for lung cancer screening based on age and smoking history.
Low-dose computed tomography (LDCT) of the chest is indicated.
The USPSTF recommends annual LDCT for adults aged 50 to 80 with a 20 pack-year or greater smoking history who currently smoke or have quit within the past 15 years.
3
Assess the patient's need for osteoporosis screening.
Dual-energy x-ray absorptiometry (DEXA) is indicated.
The USPSTF recommends routine bone density screening for all women aged 65 and older to prevent osteoporotic fractures.
4
Determine if abdominal aortic aneurysm (AAA) screening is indicated given her family history and smoking status.
Abdominal duplex ultrasonography is NOT indicated.
Routine AAA screening is recommended only for men aged 65 to 75 who have ever smoked. There is insufficient evidence to routinely screen women who have smoked.
