Which supplies are essential when preparing for a bolus?

The selection of supplies essential for preparing a bolus relates primarily to the administration of medication or contrast agents for imaging purposes. In this context, a bolus often refers to a rapid administration of a substance, typically through an intravenous route.

The correct answer highlights the need for a syringe, a butterfly needle, a tourniquet, and the contrast or medications themselves. The syringe is vital for holding and delivering the medication or contrast efficiently. The butterfly needle, also known as a butterfly catheter, is specifically designed for easy access to veins, providing greater stability and comfort during bolus administration. The tourniquet is crucial for engorging the veins, making venipuncture easier and more successful. Lastly, having the contrast or medications readily available is fundamental to perform the bolus effectively.

The other provided choices may lack some critical components necessary for successful bolus administration. For instance, while some options include gloves or tape, they do not address the specific access and delivery requirements needed for bolus administration, such as the butterfly needle and the use of a tourniquet. Understanding this selection of tools ensures healthcare providers can administer boluses safely and effectively, contributing to patient care during radiological procedures.
