Assignment:

Case 1:

Clinical Notes: Patient reports to the clinic with increasing dysmenorrhea. She describes the pain as cyclical, increasing in intensity during menstruation. The pain started as mild cramps several years ago, but has progressively become more severe and is now debilitating. The patient denies any abnormal vaginal discharge.

Current vital signs: BP 110/82, HR 68 bpm, Temperature 98.4°F

Her gynecologist completes a pelvic exam and notes no structural abnormalities of the vagina or cervix. The gynecologist suspects endometriosis or polycystic ovarian syndrome and recommends imaging studies for diagnosis and treatment.

Question 1: Why would the physician order imaging tests instead of lab tests?

Question 2: If Ms. Miller has polycystic ovarian syndrome, what other symptoms might you expect her to exhibit?

Current vital signs: BP 122/78, HR 82 bpm, Temperature 98.2°F

The physician suspects prostate issues and suggests a digital rectal exam and prostate-specific antigen test.

Question 1: If the issue is related to a structural abnormality of the prostate, which other symptoms (not mentioned here) may he experience?

Question 2: What is a prostate-specific antigen test and why was it ordered in this case?

Question 3: Mr. Heinrich's digital rectal exam revealed abnormal bumps. Which other diagnostic procedures may be recommended as a follow-up?
