A patient reports they took metformin before their contrast-enhanced CT. What is the primary concern?
Answer: Risk of lactic acidosis if renal function is compromised
Metformin should be withheld before and after iodinated contrast because contrast-induced nephropathy can impair metformin clearance, leading to lactic acidosis.
When positioning a combative patient for imaging, the radiologic technologist should FIRST:
Answer: Communicate calmly and assess the cause of agitation
De-escalation through calm communication and identifying the cause of agitation is the first priority before considering physical or chemical restraints.
Which of the following flow rates is appropriate when administering oxygen via nasal cannula to a patient with no known COPD?
Answer: 2-6 L/min
Nasal cannula delivers 24-44% FiO2 at flow rates of 2-6 L/min for patients without COPD or hypoxic drive concerns.
A patient's IV site appears puffy, cool, and pale during contrast injection. The technologist should:
Answer: Stop the injection immediately and remove the IV
These signs indicate extravasation; the injection must be stopped immediately and the IV removed to prevent further contrast infiltration into tissue.
Which isolation precaution category requires the technologist to wear a gown, gloves, and eye protection when entering the room?
Answer: Droplet precautions
Droplet precautions require a surgical mask, gown, gloves, and eye protection for care activities that may cause splashing or spraying of secretions.
A patient undergoing fluoroscopy suddenly states, 'I feel like something terrible is about to happen.' This is MOST likely:
Answer: A classic sign of anaphylaxis prodrome
A sense of impending doom is a classic prodromal symptom of anaphylaxis and requires immediate cessation of the procedure and emergency response.
Which of the following is the MOST important action before transferring a patient with a suspected spinal injury from the stretcher to the imaging table?
Answer: Ensure adequate personnel and use log-roll technique
A minimum of three trained personnel using a log-roll or lift technique maintains spinal alignment and prevents further neurological injury during transfer.
