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 C

Explanation

A. While blood vessel spasms can occur after a stroke, t-PA does not directly affect them.
B. Platelet aggregation is the process by which platelets stick together to form a clot. t-PA dissolves clots, but it does not prevent their formation.
C. Tissue plasminogen activator (t-PA) is a medication that can dissolve blood clots. In the case of a thrombotic stroke, a blood clot has blocked blood flow to the brain. By dissolving the clot, t-PA can restore blood flow and limit brain damage.
D. t-PA does not have any direct effect on the risk of infection in the brain.

A. Discuss the precipitating factors that caused the symptoms B. Schedule a STAT computed tomography (CT) scan of the head C. Prepare to administer recombinant tissue plasminogen activator (t-PA) D. Notify the Speech Pathologist for an emergency consult

Correct Answer is B

Explanation

A.While it's important to gather information about the client's symptoms, the priority in this situation is to determine the underlying cause of the neurological symptoms. A CT scan can quickly identify if there's been a stroke or other brain injury.
B.This is the most appropriate and urgent intervention. A CT scan can rapidly identify if the client has had a stroke, which is a time-sensitive medical emergency. Early diagnosis and treatment are crucial for minimizing brain damage and improving outcomes.
C.t-PA is a medication used to dissolve blood clots in the brain, but it is only effective if given within a specific time window after the onset of stroke symptoms. Without a confirmed diagnosis of stroke from a CT scan, administering t-PA could be harmful.
D.While a speech pathologist may be involved in the client's care later on, the priority is to determine the underlying cause of the neurological symptoms and initiate appropriate treatment. A CT scan is essential for this purpose.
