The physician recommends a carotid endarterectomy for a client with atherosclerosis and a history of transient ischemic attacks (TIAS). The nurse explains that this procedure involves:
bypassing the plaques with another artery.
removal of plaques in the artery in the neck.
brain surgery to remove the diseased plaques.
resection of a diseased artery in the brain and replacing it with a Gortex graft.
The Correct Answer is B
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.

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.

Explanation
Allogeneic Transplant
Matched Donor: This refers to a donor who is not genetically identical to the recipient but has a similar tissue type. This can include unrelated donors who are matched through registries.
Sibling Donor: A sibling can be a potential donor if they have a matching tissue type. Since siblings share genes, there is a higher chance of finding a match.
Autologous Transplant
Self-Donor: In this type of transplant, the patient donates their own stem cells before undergoing treatment (such as chemotherapy or radiation). These cells are then stored and re-infused after treatment to help the body recover.
Syngeneic Transplant
Twin Donor: This involves a donor who is an identical twin. Since identical twins have the same genetic makeup, there is a perfect match, reducing the risk of graft-versus-host disease (GVHD).
