ARRT Patient Care 2

Question 1

A patient with a serum creatinine of 1.9 mg/dL is scheduled for a contrast-enhanced CT. What is the most appropriate action?

Accepted Answer

Notify the radiologist and consider pre-hydration or alternative imaging

Answer

Elevated creatinine indicates reduced renal function, requiring radiologist consultation and possible pre-hydration or withholding contrast to prevent contrast-induced nephropathy.

Question 2

Which organization's guidelines most commonly govern the use of iodinated contrast media in CT scanning in the US?

Accepted Answer

American College of Radiology (ACR)

Answer

The ACR publishes widely adopted Manual on Contrast Media that guides safe use of iodinated and gadolinium-based contrast agents.

Question 3

When positioning an unresponsive patient for a head CT, the technologist should first:

Accepted Answer

Ensure airway, breathing, and circulation are assessed

Answer

ABCs (airway, breathing, circulation) must be confirmed before any positioning to ensure patient safety.

Question 4

A patient states they are allergic to shellfish. How should the technologist respond regarding iodinated contrast?

Accepted Answer

Document the allergy and notify the radiologist for risk assessment

Answer

Shellfish allergy does not directly predict iodinated contrast reactions, but any allergy history should be documented and the radiologist informed to guide pre-medication decisions.

Question 5

Which of the following is a sign of a severe allergic reaction to contrast media requiring immediate intervention?

Accepted Answer

Laryngeal edema with stridor

Answer

Laryngeal edema with stridor is a life-threatening anaphylactic response requiring immediate epinephrine and emergency support.
