When performing a breast examination, the nurse knows that it is especially important to examine the upper, outer quadrant of the breast.
The reason for this is that the upper outer quadrant is:

The largest quadrant of the breast.

The location of most breast tumors.

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

Where most of the suspensory ligaments attach.

Answer and Explanation

The Correct Answer is B

Choice A rationale

The upper, outer quadrant is indeed a significant portion of the breast tissue, but its size alone does not explain its importance in breast examination. The distribution of glandular tissue throughout all quadrants contributes to breast volume, but density varies.

Choice B rationale

The upper outer quadrant is the most common location for breast tumors because it contains the largest amount of glandular tissue. This anatomical concentration increases the probability of abnormal cell proliferation, leading to a higher incidence of cancerous lesions in this area.

Choice C rationale

While any breast quadrant can experience injury or calcifications, the upper outer quadrant is not inherently more prone. Calcifications often result from benign processes or can be associated with malignancy, but their predisposition isn't quadrant-specific based on injury.

Choice D rationale

Suspensory ligaments (Cooper's ligaments) are fibrous tissues providing breast support and attach throughout the breast tissue to the underlying fascia and overlying skin. Their attachment is not concentrated solely in the upper outer quadrant, but rather distributed across the entire breast.

Correct Answer is ["147.9"]

Explanation

Step 1: Convert fluid ounces to milliliters. 1 fl. oz = 29.5735 mL.

Step 2: Multiply the given fluid ounces by the conversion factor. 5 fl. oz × 29.5735 mL/fl. oz = 147.8675 mL.

Step 3: Round the answer to the nearest tenth. 147.9 mL.

A. Instill 5 ml of water to rinse the tube. B. Check the tube placement. C. Lay the client flat. D. Assess the client's bowel sounds.

Correct Answer is B

Explanation

Choice A rationale

Instilling water to rinse the tube is an important step after medication administration or prior to administering incompatible medications, but it is not the initial and most crucial step before delivering any drug. Placement verification is paramount.

Choice B rationale

Scientifically, confirming tube placement is the absolute first and most critical step before administering any substance, including medication, through an enteral tube. Misplaced tubes can lead to aspiration pneumonia or inefficient drug absorption, posing significant patient safety risks.

Choice C rationale

Laying the client flat may increase the risk of aspiration, especially if the tube is misplaced or if the client has impaired gag reflex. Proper positioning, typically semi-Fowler's, is crucial for safe enteral feeding and medication administration.

Choice D rationale

Assessing bowel sounds is important for evaluating gastrointestinal motility and absorption capacity before initiating or continuing enteral feedings, but it is not the primary immediate safety check required before administering a single dose of medication.
