Heparin 10,000 units subcutaneous every 12 hours is ordered for a patient after a stent placement.

The heparin is available in a 20,000 units per 1 mL concentration.

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.

Choice A rationale

Asking which client is supposed to have medications compromises patient privacy and could lead to medication errors if an incorrect patient self-identifies. Proper patient identification is a fundamental safety measure, requiring objective verification to ensure the right medication is administered to the right patient.

Choice B rationale

Stating the patient's name and expecting a confirmation ("You are Mrs. Wilson, aren't you?") is a leading question and does not independently verify identity. A patient could respond affirmatively without truly being Mrs. Wilson, increasing the risk of medication errors by not adhering to objective verification protocols.

Choice C rationale

Asking if anyone knows Mrs. Wilson is an inappropriate and unprofessional method for patient identification. It breaches patient confidentiality and does not provide a reliable or direct means of verifying the intended recipient of medication, potentially leading to significant medication safety issues.

Choice D rationale

Checking the client's identification bracelets while the client states their name provides two independent identifiers, which is a standard and highly reliable method for patient identification. This dual verification minimizes the risk of medication errors by confirming both physical identification and the patient's verbal confirmation before administration.
