Which term describes a solution such as 0.9% NaCl (normal saline) relative to red blood cells?

A. Ovarian tumor:

The symptoms (chronic pelvic pain, abdominal girth, fever, vomiting, and an elevated HE4 test) are suggestive of an ovarian tumor or potentially ovarian cancer, which may require surgical intervention like a salpingo-oophorectomy (removal of the ovary and fallopian tube).

B. Pelvic inflammatory disease (PID):

PID typically causes pelvic pain and fever, but the increased abdominal girth and elevated HE4 test make an ovarian tumor more likely.

C. Dysmenorrhea:

Dysmenorrhea refers to painful menstruation, which typically doesn't present with the severe symptoms described here, such as fever, vomiting, and abdominal girth changes.

D. Benign fibroadenoma:

Fibroadenomas are benign breast tumors, not related to the ovaries or the symptoms presented.

A. Cerebral aneurysm:

A cerebral aneurysm involves a bulging blood vessel in the brain, which could lead to rupture and bleeding. It is not associated with tremors or bradykinesia.

B. Multiple sclerosis:

MS involves demyelination causing muscle weakness and visual disturbances, but not primarily tremors and bradykinesia.

C. Amyotrophic lateral sclerosis (ALS):

ALS affects motor neurons, leading to muscle weakness and atrophy, but does not typically present with tremors or benefit from deep brain stimulation.

D. Parkinson disease:

Parkinson disease features tremors, bradykinesia (slow movements), and abnormal gait. Deep brain stimulation is an advanced therapy for symptom management in Parkinson’s.
