The nurse is doing an examination of a client's anterior thorax. The nurse recognizes that the trachea bifurcates anteriorly at the:

Xiphoid process.

Suprasternal notch.

Sternal angle.

Costal angle.

Answer and Explanation

The Correct Answer is C

A. Xiphoid process:

The xiphoid process is a small, cartilaginous extension at the inferior end of the sternum (breastbone). It does not play a role in the bifurcation of the trachea.

B. Suprasternal notch:

The suprasternal notch, also known as the fossa jugularis sternalis or jugular notch, is the visible dip in the superior part of the manubrium of the sternum between the clavicular notches. It is an important anatomical landmark for assessing the position of the trachea during emergency situations but is not the location of tracheal bifurcation.

C. Sternal angle (Angle of Louis):

The sternal angle, or Angle of Louis, is a palpable notch located at the articulation of the manubrium and the body of the sternum. It is where the second rib attaches and serves as a useful reference point for counting ribs and locating internal structures like the tracheal bifurcation.

D. Costal angle:

The costal angle is the acute angle formed by the junction of the costal margins at the xiphoid process. It is not related to the tracheal bifurcation.

Correct Answer is A

Explanation

A. Auricle (Pinna):

The auricle, also known as the pinna, is the visible external part of the ear. It consists of movable cartilage and skin. When administering eardrops, pulling the auricle up and back helps to straighten the ear canal, allowing the drops to enter the ear effectively.

B. Mastoid Process:

The mastoid process is a bony prominence located behind the ear. It is not a part of the outer ear structure involved in administering eardrops.

C. Outer Meatus:

The outer meatus, also known as the external acoustic meatus or ear canal, is the tube-like structure leading from the auricle to the eardrum. It is the passage through which eardrops are administered. Pulling the auricle up and back helps to straighten the outer meatus for the proper administration of eardrops.

D. Concha:

The concha refers to the bowl-shaped depression next to the ear canal. While it is a part of the outer ear, pulling the concha is not a technique used for administering eardrops. The auricle, specifically, is manipulated to facilitate the process.

A. The best time to perform a BSE is 4 to 7 days after the first day of the menstrual period. B. If she suspects that she is pregnant, then the woman should not perform a BSE until her baby is born. C. The best time to perform BSE is in the middle of the menstrual cycle. D. The woman needs to perform BSE only bimonthly unless she has fibrocystic breast tissue.

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.
