How to push IV medication through the heparin lock device
It’s your first day being on duty at the medical ward as a student nurse and you’re trying to learn everything that you could. Upon accompanying the staff nurse in her rounds, you note that she is carrying a syringe and is about to administer IV medication to a patient who has no IV. You look around the room for IV bottles, but still you can’t find any.
“Umm, excuse me ma’am. Is that for the patient?” you ask the staff nurse.
“Yes, it is,” she answers.
“But he has no IV line”
“Oh, Ms. X, this is to be given through the hep lock” she says as she motions to that tiny yellow thing sticking out from the patient’s hand.
Oh, that’s a heplock? You ask yourself since it’s your first time to see one and wonder how one gives medications through it
