CET Patient Care & Safety Protocols 3

Question 1

What is the correct procedure for cleaning ultrasound gel from a transducer after a routine TTE examination?

Accepted Answer

Wipe with a soft cloth or gauze, then apply an approved disinfectant wipe

Answer

Gel should be wiped off with a soft cloth, followed by application of an approved low-level disinfectant wipe per manufacturer and facility protocols.

Question 2

A patient scheduled for a TEE reports eating a full meal 2 hours before the procedure. What is the most appropriate action?

Accepted Answer

Postpone the TEE to ensure adequate NPO status

Answer

TEE requires a minimum fasting period (typically 4–6 hours) to reduce aspiration risk; the procedure must be postponed if NPO requirements are not met.

Question 3

When obtaining informed consent for a TEE from a patient who does not speak English, what is required?

Accepted Answer

A qualified medical interpreter must be used

Answer

A qualified medical interpreter must be used to ensure the patient fully understands the procedure, risks, and alternatives before providing informed consent.

Question 4

A patient with an implanted cardiac device is referred for echocardiography. What is the primary safety concern regarding ultrasound equipment?

Accepted Answer

The device may interfere with image quality but poses no safety risk

Answer

Diagnostic ultrasound does not affect implanted cardiac devices; however, the device may create imaging artifacts that reduce image quality.

Question 5

Which standard precaution applies when a patient has an open wound near the echocardiography scan site?

Accepted Answer

Use exam gloves and cover the wound with an occlusive dressing before scanning

Answer

Donning exam gloves and covering the open wound with an occlusive dressing protects both the patient and technician while allowing the exam to proceed safely.
