The nurse is preparing a client with breast cancer for BRCA1 and BRCA2 genetic testing. Which pathophysiological process should the nurse use to support client teaching?

The choice of treatment is best determined by the sensitivity of these genetic markers.

BRCA1 and BRCA2 provide protection of mature, functioning breast and ovarian cells.

Mutations in BRCA1 or BRCA2 identify a client’s risk for cancerous cell development in breast tissue.

The prognosis of breast cancer is most successful when these markers are inherited mutations.

Answer and Explanation

The Correct Answer is C

Choice A rationale
While the sensitivity of genetic markers can influence the choice of treatment, it is not the primary pathophysiological process involved in BRCA1 and BRCA2 genetic testing. The main purpose of these tests is to identify genetic mutations that increase the risk of developing certain types of cancer.
Choice B rationale
BRCA1 and BRCA2 do play a role in protecting mature, functioning breast and ovarian cells. However, this is not the primary reason for conducting BRCA1 and BRCA2 genetic testing. The main purpose of these tests is to identify mutations that increase cancer risk.
Choice C rationale

This is the correct answer. Mutations in BRCA1 or BRCA2 can significantly increase a person’s risk for developing breast and ovarian cancer. Therefore, identifying these mutations through genetic testing can help determine a person’s cancer risk.
Choice D rationale
While inherited mutations in BRCA1 and BRCA2 can influence the prognosis of breast cancer, the primary purpose of BRCA1 and BRCA2 genetic testing is to identify mutations that increase cancer risk, not to determine prognosis.

Correct Answer is B

Explanation

Choice A rationale
Reinforcing the connection of the chest tube to the container with tape is not the immediate action to be taken when a client becomes suddenly short of breath and anxious. This action might be necessary if the connection between the chest tube and the container is loose, but it does not address the immediate need of the client.
Choice B rationale
If a client with a chest tube becomes suddenly short of breath and anxious, the nurse should immediately clamp the chest tube with a plastic clamp. This is because the chest tube might have been disconnected from the water seal chamber, and clamping the tube can prevent air from entering the pleural space and causing a tension pneumothorax.
Choice C rationale

Applying an occlusive dressing over the site of the chest tube is not the immediate action to be taken when a client becomes suddenly short of breath and anxious. This action might be necessary if the chest tube is accidentally removed, but it does not address the immediate need of the client.
Choice D rationale
Ensuring that the chest tubing is neither kinked nor hanging low is an important part of the ongoing care for a client with a chest tube, but it is not the immediate action to be taken when a client becomes suddenly short of breath and anxious.

A. Iron deficiency anemia B. Vitamin B12 deficiency C. Folic acid deficiency anemia

Correct Answer is {"A":{"answers":"A,B"},"B":{"answers":"C,B"},"C":{"answers":"B"}}

Explanation

Choice A rationale

Chronic alcoholism is often associated with both Vitamin B12 and Folic acid deficiency anemia. Alcohol interferes with the absorption of these vitamins in the gut, leading to their deficiency.

Choice B rationale

Malabsorption syndrome can lead to Iron deficiency anemia, Vitamin B12 deficiency anemia, and Folic acid deficiency anemia. In malabsorption syndrome, the small intestine can’t absorb enough of certain nutrients and fluids.

Choice C rationale

Dietary deficiency can result in Iron deficiency anemia, Vitamin B12 deficiency anemia, and Folic acid deficiency anemia. These types of anemia can occur when the body doesn’t have enough of the vitamins needed to produce enough healthy red blood cells.
