Correct Answer is D
Explanation
A. Remove dental plates before the procedure. Dental plates do not interfere with a mammogram, so removing them is unnecessary.
B. Do not eat or drink anything for 4 hr before the procedure. There are no dietary restrictions required before a mammogram, so this instruction is not necessary.
C. An IV will be started before the procedure. An IV is not required for a mammogram, which is a non-invasive imaging procedure.
D. Do not apply any deodorant before the procedure. Patients are advised not to apply deodorant, lotions, or powders before a mammogram because these products can show up as artifacts on the mammogram images, potentially leading to misinterpretation.
