A technologist prepares to inject contrast for an emergency urogram on a patient with bloody sputum and an uncovered cough, using a single-dose vial and a sharps container at bedside. Which combination of Standard Precautions, PPE, and injection practice provides safe care during the IV contrast administration?

For bloody sputum and an uncovered cough during IV contrast administration, safe care combines hand hygiene, gloves and a mask, one use of the single-dose vial, and intact sharps disposal. Cleaning your hands before contact limits transfer, gloves help block blood exposure, and a mask helps limit droplet inhalation and dispersion. A single-dose vial must be discarded after puncture; preservative-free contents cannot be saved for later use, even for the same patient, because bacterial growth can occur rapidly. Directly discarding the intact syringe in the bedside sharps container avoids needlestick risk. The combination that substitutes protective eyewear for a mask fails to address respiratory protection: eyewear controls splashes but provides no filtration or source control for cough droplets. Saving an opened single-dose vial for the same patient later fails safe injection practice because the vial is for one use and must be discarded after puncture. Recapping the needle with a one-hand scoop before disposal adds handling and needlestick risk when a sharps container is at bedside; discard the intact unit directly instead. An exam caveat is that same-patient reuse language does not override single-dose discard rules, and eye protection does not substitute for a mask. As a practical check, perform hand hygiene, confirm mask coverage and glove integrity, verify the single-dose label, give the dose once, and place the intact syringe directly in the bedside container.
