Answer:
Options B, injection
Explanation:
Heparin is an anticoagulation medication used to prevent blood clots from forming within the heart, lungs, brain, and blood vessels, thereby mitigating conditions such as pulmonary embolism, ischemic stroke, deep vein thrombosis (DVT), and general thromboembolism. It can also be used to flush intravenous (IV) lines in order to keep them patent (open) to ensure access to the patient's bloodstream.
Heparin is generally available in two forms of injection, option B.
The first form of injection comes by way of the medication being mixed within a bag with 0.45% sodium chloride solution. This is salt water that is about half as "salty" as the normal blood composition, a mixture known as a hypotonic solution. This bag is primed with IV tubing, programmed using an infusion pump, and hooked up to the patient via a peripheral IV catheter in a patent vein. Drip by drip, the medication is then delivered to the patient.
The second form of injection involves a needle delivering the medication subcutaneously into the adipose tissue. The abdomen, thigh, hip, or back of the patient's arm is pinched enough to separate the adipose from the underlying muscle layers and a needle around 5/8 of an inch is inserted at a 90° angle into this fatty tissue. Once the medication is dispensed, the pinch is released, the needle is removed, and the needlestick prevention safety mechanism is engaged. This form is called low-molecular-weight heparin (LMWH), with one example being enoxaparin (brand name Lovenox).
