A client diagnosed with prostate cancer asks the nurse the importance of the prostate specific antigen (PSA). The nurse explains to the client that the PSA:

is effective in diagnosing other male cancers

is decreased in the presence of cancer

is a screening tool for prostate cancer

is used as a definitive diagnosis for prostate cancer

Answer and Explanation

The Correct Answer is C

A.  PSA is primarily associated with prostate health and is not an effective marker for diagnosing other male cancers. While elevated PSA levels can sometimes indicate issues related to the prostate, they are not used for diagnosing other types of cancer.
B.   In fact, PSA levels are usually increased in the presence of prostate cancer. While there can be some conditions that lead to a decrease in PSA levels, cancer itself typically raises PSA levels.
C.  PSA is commonly used as a screening tool for prostate cancer. Elevated PSA levels may prompt further investigation, including biopsies, to determine if cancer is present. However, it’s important to note that elevated PSA can also occur due to benign conditions like prostatitis or benign prostatic hyperplasia (BPH).
D.  While PSA levels can indicate the possibility of prostate cancer, they do not provide a definitive diagnosis. A diagnosis of prostate cancer typically requires further testing, such as a prostate biopsy, to confirm the presence of cancerous cells.

Correct Answer is D

Explanation

A. While it's true that ulcers can be a serious complication of PAD and require careful management, exercise is generally encouraged in patients with PAD as long as it is safe and supervised. Patients should consult their healthcare provider about appropriate exercise, but not exercising altogether can worsen their condition.
B. Buying shoes in the afternoon is advisable because feet can swell throughout the day. It helps ensure a better fit and reduces the risk of blisters or skin breakdown, which is particularly important for clients with PAD.
C. This statement is generally correct, as dangling the legs can help improve circulation in some cases. Clients with PAD often experience relief when their legs are in a dependent position, as it may help increase blood flow to the extremities. However, they should also be encouraged to avoid prolonged periods of sitting.
D. This statement may indicate a misunderstanding. Compression stockings are typically used for venous issues rather than arterial diseases like PAD. In patients with PAD, wearing compression stockings may not be appropriate and could potentially compromise arterial blood flow.

A. 1 unit per 1mL B. 10 units per 1 mL C. 100 units per 1 mL D. 1000 units per 1 mL

Correct Answer is C

Explanation

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.
