The nurse recognizes that the following statement is true regarding the internal structures of the breast: The breast is made up of:
Glandular tissue, which supports the breast by attaching to the chest wall.
Fibrous, glandular, and adipose tissues
Primarily muscle with very little fibrous tissue.
Primarily milk ducts, known as lactiferous ducts.
The Correct Answer is B
A. Glandular tissue, which supports the breast by attaching to the chest wall: Glandular tissue is indeed a part of the breast structure, but it is not responsible for supporting the breast by attaching to the chest wall. It's the Cooper's ligaments, which are fibrous connective tissue, that provide structural support.
B. Fibrous, glandular, and adipose tissues: This statement is correct. The breast is composed of glandular tissue (responsible for milk production), fibrous tissue (including Cooper's ligaments for support), and adipose tissue (fat).
C. Primarily muscle with very little fibrous tissue: The breast contains very little muscle tissue. The main supportive structure is fibrous tissue, not muscle.
D. Primarily milk ducts, known as lactiferous ducts: Milk ducts are part of the glandular tissue and are responsible for carrying milk. However, the breast is not primarily made up of milk ducts; it consists of a combination of glandular, fibrous, and adipose tissues.

Correct Answer is A
Explanation
A. The best time to perform a BSE is 4 to 7 days after the first day of the menstrual period:
This statement is correct. Performing BSE a few days after the menstrual period ensures that the breasts are less likely to be swollen or tender, which can make it easier to detect any unusual changes.
B. If she suspects that she is pregnant, then the woman should not perform a BSE until her baby is born:
This statement is incorrect. Pregnant women can still perform breast self-examinations. In fact, it's important for pregnant women to be aware of any changes in their breasts.
C. The best time to perform BSE is in the middle of the menstrual cycle:
This statement is not as accurate as the first choice. While it's true that performing BSE a few days after the menstrual period can be easier due to reduced breast tenderness, it doesn't necessarily mean the middle of the menstrual cycle for every woman. The timing can vary based on an individual's menstrual cycle.
D. The woman needs to perform BSE only bimonthly unless she has fibrocystic breast tissue:
This statement is incorrect. Regular monthly breast self-examinations are recommended for all women, regardless of whether they have fibrocystic breast tissue or not. Detecting changes early is crucial for breast health.
Correct Answer is C
Explanation
In this sequence:
Vena cava brings deoxygenated blood from the body into the right atrium.
Blood flows from the right atrium to the right ventricle through the tricuspid valve.
The right ventricle pumps blood into the pulmonary artery to the lungs.
In the lungs, blood is oxygenated and returns to the heart via the pulmonary veins into the left atrium.
From the left atrium, blood moves to the left ventricle through the bicuspid (mitral) valve.
The left ventricle then pumps oxygenated blood into the body through the aorta.
This sequence represents the systemic and pulmonary circulation of the heart.
