A nurse is reinforcing teaching with a client who is scheduled for a mammogram. Which of the following instructions should the nurse include in the teaching?

A. Refrain from using deodorant on the morning of the test: Deodorants, powders, lotions, and perfumes applied to the breast or axillary area can contain metallic particles such as aluminum. These substances may appear as radiopaque artifacts on the mammogram and mimic microcalcifications, potentially leading to false-positive findings or the need for repeat imaging. B. Shower with an antimicrobial solution before the test: Mammography is a noninvasive radiographic procedure that does not require sterile preparation. Antimicrobial cleansing is unnecessary because there is no incision or breach of skin integrity. Routine hygiene is sufficient prior to the examination. C. Avoid taking aspirin for 1 week prior to the test: Mammography does not involve tissue puncture or invasive sampling, so there is no increased bleeding risk associated with aspirin use. Antiplatelet medication adjustments are typically considered before invasive procedures such as biopsies, not routine imaging studies. D. Do not eat or drink after midnight the night before the test: Fasting is not required for a mammogram because the procedure does not involve sedation or anesthesia. Clients may eat, drink, and take prescribed medications as usual prior to the appointment.
