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.
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 A
Explanation
Choice A rationale
The vastus lateralis muscle is the preferred intramuscular injection site for infants and children due to its large muscle mass and lack of major nerves or blood vessels, minimizing the risk of injury. This site is easily accessible and provides a safe area for medication absorption in developing musculature.
Choice B rationale
The ventrogluteal site is generally considered safe and effective for intramuscular injections, but it requires precise anatomical landmark identification, which can be challenging in infants and young children, increasing the risk of sciatic nerve injury if landmarks are not accurately identified.
Choice C rationale
The dorsogluteal site is contraindicated for intramuscular injections in infants and children due to the risk of sciatic nerve damage. The sciatic nerve runs through this area, and the muscle mass is not fully developed in younger patients, making it a hazardous site.
Choice D rationale
The deltoid muscle is too small and underdeveloped in infants and young children to safely accommodate intramuscular injections. Its limited muscle mass increases the risk of injury to underlying nerves and blood vessels, and absorption capacity is reduced.
Correct Answer is ["25"]
Explanation
Step 1 is to determine the total infusion time in minutes. 1 L = 1000 mL. 1000 mL ÷ (150 mL/h) = 6.666. hours. 6.666. hours × (60 min/hour) = 400 minutes.
Step 2 is to calculate the flow rate in drops per minute. (1000 mL ÷ 400 min) × (10 gtts/mL) = 25 gtts/min. The flow rate is 25 gtts/min.
