Final answer:
The correct instruction for using a birth control patch like Ortho Evra is to apply a new patch once a week for three weeks on certain body areas like the lower abdomen or outer arm, then have a one-week break. For a nitroglycerin patch, typically used for angina, the patch is placed on a flat area and rotated according to a prescribed schedule.
Step-by-step explanation:
The correct statement a nurse should include when teaching a patient how to use a nitroglycerin transdermal patch is none of the options provided directly relate to nitroglycerin use. However, if we were discussing the birth control patch such as Ortho Evra, the correct instruction would be different. Since the question seems to conflate a nitroglycerin patch with a birth control patch, let's clarify the instructions based on the description of the birth control patch provided. The patch is worn on the lower abdomen, buttocks, outer arm, or upper body, but not on the foot or the chest specifically. It is important to change the patch once a week for three weeks and then have one week off for a period. This cycle is repeated monthly. In case of a nitroglycerin patch, which is used for angina, the instructions typically involve placing the patch on a flat area of the body, such as the chest or the upper arm, and patches are usually rotated and removed according to a specific schedule to prevent tolerance, typically every 12-14 hours, with a nitrate-free period to ensure effectiveness.
