What is the first step in administering a trans-dermal nitroglycerin patch?

Washing hands is a crucial first step in the process of administering a transdermal nitroglycerin patch. This step ensures that any potential contaminants or pathogens are removed from your hands, which helps prevent infection and maintains hygiene standards. Proper hand hygiene is vital in medication administration to safeguard both the patient's health and the caregiver's health.

Additionally, following hand washing, other steps like locating and removing the old patch and preparing the skin for the new patch would continue the process. However, starting with clean hands is fundamental before touching either the medication or the patient's skin. This practice is an essential part of protocol in any healthcare setting, ensuring safety and efficacy in medication delivery.
