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. Wheezes:
Wheezes are continuous, high-pitched, whistling lung sounds that are heard especially during expiration and sometimes during inspiration. They are caused by the rapid movement of air through narrowed or constricted airways, which is common in conditions like asthma. Wheezing is a characteristic adventitious sound associated with asthma and other obstructive respiratory disorders.
B. Whispered Pectoriloquy:
Whispered Pectoriloquy is an increased loudness of whispering noted during auscultation with a stethoscope on the lung fields. This phenomenon occurs when sound is transmitted clearly through consolidated or compressed lung tissue, making whispered sounds more distinct. It is a sign of lung consolidation, often seen in conditions like pneumonia.
C. Bronchial Sounds:
Bronchial sounds are harsh, high-pitched sounds heard over the trachea and the large bronchi. These sounds are normally heard during expiration. If they are heard over peripheral lung areas, it can indicate consolidation or compression of lung tissue, possibly due to pneumonia or tumor.
D. Bronchophony:
Bronchophony is a phenomenon in which spoken sounds are heard more clearly and distinctly through the stethoscope on auscultation of the lungs. Normally, sounds are muffled during auscultation. Increased clarity of spoken sounds can indicate lung consolidation, similar to whispered pectoriloquy, and is often associated with conditions like pneumonia.
Correct Answer is D
Explanation
A. A shiny, pearly white color tympanic membrane: This is a normal finding. A healthy tympanic membrane often appears shiny and pearly white.
B. The presence of cerumen: This is a normal finding. Cerumen, or earwax, is a natural substance that helps protect the ear canal.
C. The presence of a cone of light: This is a normal finding. The cone of light is a reflection of the otoscope light on the tympanic membrane and is a normal variation.
D. A yellow or amber color to the tympanic membrane: This is considered an abnormal finding. A yellow or amber coloration of the tympanic membrane can indicate the presence of fluid or infection behind the eardrum, which may be a sign of otitis media or other ear conditions.
