A patient is ordered 20 unit/kg IV bolus of Heparin. The patient weighs 154 lbs. Heparin is supplied 25,000 units/250 mL. How many mL will the nurse administer? (round to the nearest whole number)

A. This response is relevant and helps assess the characteristics of the lump. Pain can be an important factor in differentiating between conditions, such as epididymitis, testicular torsion, or tumors. However, while it is a useful question, it may not provide a comprehensive assessment of the situation.
B. This question can be relevant depending on the underlying cause of the lump. Issues with urination may suggest a problem related to the prostate or bladder rather than the testicle itself. While it can help assess urinary tract involvement, it may not directly address the significance of the lump in the testicle.
C. This question is important in the context of sexually transmitted infections (STIs), which can cause scrotal swelling or lumps due to conditions like epididymitis or orchitis. However, it does not directly assess the lump itself, making it less focused on the immediate concern.
D. This question addresses the possibility of an STI and related conditions. While it is relevant, it is not the best immediate question concerning the lump in the testicle. The presence of discharge may not directly correlate with the testicular lump itself.

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.
