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 B

Explanation

A. A carotid endarterectomy does not involve bypassing the plaques; rather, it directly addresses the blockage.
B. Carotid endarterectomy is a surgical procedure that involves making an incision in the neck to access the carotid artery, where the surgeon removes the atherosclerotic plaques that are causing narrowing and restricting blood flow. This helps reduce the risk of stroke.
C. Carotid endarterectomy is not brain surgery; it is performed on the carotid arteries in the neck. The procedure aims to prevent strokes by improving blood flow to the brain, but it does not involve surgery on the brain itself.
D. This description does not accurately reflect carotid endarterectomy. The procedure does not involve resecting an artery in the brain or using a graft; rather, it focuses on removing plaques from the carotid artery in the neck.

A. a history of multiple sex partners. B. a long history of smoking. C. prolonged exposure to estrogen. D. multiple pregnancies.

Correct Answer is C

Explanation

A. While having multiple sexual partners is associated with an increased risk of sexually transmitted infections (STIs), it is not considered a significant risk factor for uterine cancer specifically. STIs can contribute to other reproductive cancers, such as cervical cancer, but they are not directly linked to the development of uterine cancer.
B. Smoking is a risk factor for various cancers, including cervical and lung cancers, but its association with uterine cancer is not as strong. While some studies suggest a potential link, it is not recognized as a primary risk factor for uterine cancer.
C. Prolonged exposure to unopposed estrogen (estrogen not balanced by progesterone) is the primary risk factor for uterine cancer. This can occur in situations such as obesity (where adipose tissue produces estrogen), hormone replacement therapy without progesterone, and certain medical conditions like polycystic ovary syndrome (PCOS).
D. Having multiple pregnancies is generally considered to have a protective effect against uterine cancer. Pregnancy reduces the number of menstrual cycles a woman has over her lifetime, which can lead to lower lifetime exposure to estrogen.
