UTC Ultrasound Technologist Patient Care & Safety Protocols 2

Question 1

A patient reports a latex allergy before a transrectal ultrasound. What is the most appropriate action?

Accepted Answer

Use a latex-free probe cover and notify the radiologist

Answer

Latex-free probe covers must be used for patients with latex allergies to prevent allergic reactions, and the radiologist should be informed.

Question 2

When scanning a pregnant patient in the third trimester, which position best prevents supine hypotensive syndrome?

Accepted Answer

Left lateral decubitus

Answer

Left lateral decubitus positioning shifts the uterus off the inferior vena cava, preventing compression that causes supine hypotensive syndrome.

Question 3

Which cleaning method is required for endocavitary ultrasound transducers between patients?

Accepted Answer

High-level disinfection using an EPA-registered chemical

Answer

Endocavitary transducers contact mucous membranes and require high-level disinfection with an EPA-registered disinfectant per CDC guidelines.

Question 4

A patient becomes diaphoretic and lightheaded during an abdominal ultrasound. The first priority is to:

Accepted Answer

Lower the head of the table and call for assistance

Answer

A vasovagal response requires lowering the patient's head (Trendelenburg or supine) to restore cerebral perfusion and calling for clinical support.

Question 5

The thermal index (TI) is most relevant when performing ultrasound on which tissue type?

Accepted Answer

Bone and soft tissue interfaces

Answer

The thermal index is especially relevant at bone-soft tissue interfaces (TIB) because bone absorbs more ultrasound energy and generates more heat.
