Malignant plasma cells secrete substances to stimulate the creation of new blood vessels to enhance the growth of the clusters of plasma cells. This is the process of

A. Flush the toilet twice after use: Brachytherapy involves the use of radioactive materials, and bodily fluids can carry radiation. Flushing the toilet twice ensures that any potential radioactive material in urine is adequately cleared, minimizing the risk of exposure to others.

B. Wash laundry unseparated from others: Laundry from a client undergoing brachytherapy should be washed separately to prevent the potential spread of radioactive materials to other clothes and individuals.

C. Wear a lead apron for one week after the treatment: Wearing a lead apron is not typically necessary for a week after brachytherapy. Precautions focus more on minimizing exposure to others, particularly through body fluids, rather than continuous use of lead aprons.

D. Stay in a standing position while urinating: This instruction is not relevant for brachytherapy safety in terms of limiting exposure to others. Its relevance might be to prevent splashing or ensure complete bladder emptying, but it doesn't directly address limiting radiation risk.

A. Visual disturbances: Visual disturbances are not a typical symptom of ovarian cancer. They are more often associated with conditions such as neurological issues or metabolic disturbances. Ovarian cancer primarily affects the reproductive and gastrointestinal systems.

B. Back pain: Back pain is a common symptom of ovarian cancer, particularly when the tumor grows and presses on surrounding structures. It may also be a result of ascites or metastasis to the lower abdomen or pelvis.

C. Persistent indigestion: Persistent indigestion is a common symptom of ovarian cancer, especially as the tumor grows and puts pressure on the digestive system. It can cause bloating, nausea, and feelings of fullness, often contributing to gastrointestinal discomfort.

D. Pelvic or abdominal pain: Pelvic or abdominal pain is a hallmark symptom of ovarian cancer. As the tumor develops, it may cause discomfort or pain in the pelvic region, often accompanied by bloating or pressure in the lower abdomen.

E. Ascites: Ascites, or the accumulation of fluid in the abdominal cavity, is a classic sign of advanced ovarian cancer. It occurs when cancer spreads to the peritoneum and interferes with the body's ability to drain fluid properly, leading to swelling in the abdomen.

F. Unexplained weight loss: Unexplained weight loss can occur with ovarian cancer, particularly in later stages. This may result from changes in appetite, increased metabolic demand, or complications like ascites.

G. Frequent urination: Frequent urination is a symptom that can be associated with ovarian cancer, particularly when the tumor presses on the bladder. This pressure can lead to the sensation of needing to urinate more often, even if the bladder is not full.
