In performing a breast examination, the nurse knows that examining the upper outer quadrant of the breast is especially important.
The reason for this is that the upper quadrant is:

More prone to injury and calcifications than other locations in the breast.

Where most of the suspensory ligaments attach.

The largest quadrant of the breast.

The location of most breast tumors.

Answer and Explanation

The Correct Answer is D

Choice A rationale

While the upper outer quadrant can be prone to injury and calcifications, this is not the primary reason for its importance in breast examinations. Calcifications can occur in various parts of the breast and are often detected through mammography rather than physical examination.

Choice B rationale

Suspensory ligaments, also known as Cooper's ligaments, provide structural support to the breast. They attach to the skin and the underlying pectoral fascia. However, these ligaments are distributed throughout the breast and are not confined to the upper outer quadrant.

Choice C rationale

The upper outer quadrant is not the largest quadrant of the breast. All quadrants have relatively similar sizes. Therefore, the size of the quadrant is not the reason for its importance in breast examinations.

Choice D rationale

The upper outer quadrant of the breast is the most common location for breast tumors. This is because a significant portion of the breast tissue, including the axillary tail (an extension of breast tissue into the armpit), is located in this quadrant. Therefore, careful examination of this area is crucial for early detection of breast cancer.

Correct Answer is A

Explanation

Choice A rationale

Without treatment, glaucoma can lead to blindness due to the progressive damage it causes to the optic nerve. Elevated intraocular pressure damages the optic nerve fibers, leading to peripheral vision loss and eventually total blindness if untreated.

Choice B rationale

Double vision is not a common symptom of glaucoma. Instead, glaucoma typically presents with symptoms like gradual peripheral vision loss, eye pain, and halos around lights.

Choice C rationale

Glaucoma is primarily caused by increased intraocular pressure, either due to overproduction of aqueous humor or improper drainage, not inadequate fluid production.

Choice D rationale

Use of eye drops helps to control intraocular pressure but does not improve vision; it helps to prevent further damage to the optic nerve.

A. Atrial depolarization. B. Ventricular repolarization. C. Atrial repolarization. D. Ventricular depolarization.

Correct Answer is D

Explanation

Choice A rationale

Atrial depolarization is represented by the P wave on an ECG, not the QRS wave. This phase involves the electrical activation and contraction of the atria, which precedes ventricular contraction.

Choice B rationale

Ventricular repolarization is represented by the T wave, not the QRS complex. The T wave signifies the ventricles returning to their resting state.

Choice C rationale

Atrial repolarization generally occurs during the QRS complex, but it is not represented by it. The electrical activity of atrial repolarization is masked by the more significant ventricular depolarization signal of the QRS complex.

Choice D rationale

The QRS complex on an ECG represents ventricular depolarization, which is the electrical activation leading to the contraction of the ventricles. This is the correct answer as it accurately describes the QRS wave’s significance. .
