Solution
-
Thrombolytics are a type of medication that help dissolve blood clots, which can block arteries or veins. They work by activating the enzyme plasminogen, which becomes plasmin. Plasmin then breaks down the fibrin in blood clots, effectively dissolving them. Shelby was likely prescribed thrombolytics because she may have had a condition such as a heart attack, stroke, or pulmonary embolism, which are often caused by blood clots.
-
The time from the onset of symptoms is critical information when administering thrombolytics because these drugs are most effective when given soon after a blood clot forms. The sooner a clot can be dissolved, the less damage it can do to the body. For example, in the case of a stroke, quick administration of thrombolytics can help minimize brain damage.
-
Important nursing interventions when administering thrombolytics include closely monitoring the patient's vital signs, especially blood pressure and heart rate, as these drugs can cause bleeding. Nurses should also watch for signs of bleeding, such as bruising, bloody or tarry stools, or bleeding gums. Additionally, they should monitor the patient's neurological status, as changes could indicate a problem such as a stroke. Finally, nurses should educate patients about the signs of bleeding and the importance of seeking immediate medical attention if they notice any of these signs.
