The nurse receives report at 0700 on a client who has 500 mL of IV fluid left in the bag. The IV is running at 125 mL per hour. At what time should the nurse expect to change the bag (military time)?

A. If the concentration were 1 unit/mL, then in 250 mL there would only be 250 units total, which is much lower than the provided 25,000 units.
B. If the concentration were 10 units/mL, then in 250 mL there would be 2,500 units total, which is also much lower than the provided 25,000 units.
C. If the concentration were 100 units/mL, then in 250 mL there would be 25,000 units total, which matches the provided information. However, while this seems plausible, it is not the answer we calculated.
D. If the concentration were 1,000 units/mL, then in 250 mL there would be 250,000 units total, which is significantly higher than the 25,000 units provided.

A. CA-125 is primarily associated with ovarian cancer and is not a relevant tumor marker for testicular cancer. Serum ceruloplasmin is a copper-carrying protein that can be elevated in various conditions, but it is not specific for testicular cancer. Therefore, this option is not appropriate.
B. Both hCG and AFP are tumor markers specifically associated with testicular cancer. Elevated levels of these markers can indicate the presence of non-seminomatous testicular tumors. Monitoring these markers is essential for diagnosis, assessing treatment response, and detecting recurrence.
C. EPO is involved in red blood cell production and is not a tumor marker for testicular cancer. CEA is primarily associated with colorectal cancer and some other malignancies, but it is not specific for testicular cancer.
D. PSA is a tumor marker associated with prostate cancer, not testicular cancer. While hCG is relevant for testicular cancer, the inclusion of PSA makes this option inappropriate for a client with testicular cancer.
