ARRT Patient Care and Management 2

Question 1

A patient reports they took metformin before their contrast-enhanced CT. What is the primary concern?

Accepted Answer

Risk of lactic acidosis if renal function is compromised

Answer

Metformin should be withheld before and after iodinated contrast because contrast-induced nephropathy can impair metformin clearance, leading to lactic acidosis.

Question 2

When positioning a combative patient for imaging, the radiologic technologist should FIRST:

Accepted Answer

Communicate calmly and assess the cause of agitation

Answer

De-escalation through calm communication and identifying the cause of agitation is the first priority before considering physical or chemical restraints.

Question 3

Which of the following flow rates is appropriate when administering oxygen via nasal cannula to a patient with no known COPD?

Accepted Answer

2-6 L/min

Answer

Nasal cannula delivers 24-44% FiO2 at flow rates of 2-6 L/min for patients without COPD or hypoxic drive concerns.

Question 4

A patient's IV site appears puffy, cool, and pale during contrast injection. The technologist should:

Accepted Answer

Stop the injection immediately and remove the IV

Answer

These signs indicate extravasation; the injection must be stopped immediately and the IV removed to prevent further contrast infiltration into tissue.

Question 5

Which isolation precaution category requires the technologist to wear a gown, gloves, and eye protection when entering the room?

Accepted Answer

Droplet precautions

Answer

Droplet precautions require a surgical mask, gown, gloves, and eye protection for care activities that may cause splashing or spraying of secretions.
