Final answer:
Vasoactive medications should be administered using a central venous line to ensure safe, controlled, and effective drug delivery, avoiding the risks associated with other administration methods like rapid IV push or peripheral IV lines. Option c.
Step-by-step explanation:
The administration of vasoactive medications should be done with care due to their potent effects on blood vessel tone and blood pressure. These medications are typically administered using a central venous line (option c), as this method allows for controlled administration and monitoring. A central venous line ensures immediate drug delivery and effect, avoiding the slow absorption and variable effects associated with intramuscular (IM) injection.
Moreover, central venous administration reduces the risk of drug extravasation, which can occur if given through a peripheral IV line and may lead to tissue damage due to the concentrated effect of vasoactive drugs. Rapid intravenous (IV) push (option a) is not the method of choice for vasoactive drugs because it may result in sudden changes in blood pressure and potential overdose. Thus, for the safety and efficacy of treatment, the central venous route is preferred for administering vasoactive drugs.
