Echocardiogram Patient Care and Safety in Echocardiography 2

Question 1

During a transesophageal echocardiogram (TEE), a patient's oxygen saturation drops to 85%. What should the technician do first?

Accepted Answer

Alert the physician immediately and prepare to withdraw the probe

Answer

Oxygen desaturation below 90% during TEE is a safety endpoint requiring immediate physician notification and possible probe removal.

Question 2

Which document must be obtained from a competent patient before performing a transesophageal echocardiogram?

Accepted Answer

Written informed consent

Answer

Informed consent is required for invasive procedures like TEE; it documents that the patient understands the risks and agrees to proceed.

Question 3

A patient has a latex allergy. What precaution is specifically needed during an echocardiographic examination?

Accepted Answer

Use latex-free gloves and verify probe covers are latex-free

Answer

Latex-free gloves and latex-free probe covers prevent allergic reactions in latex-sensitive patients during the examination.

Question 4

When caring for a patient on droplet precautions, which personal protective equipment (PPE) is required for the echocardiography technician?

Accepted Answer

Surgical mask, gloves, and eye protection

Answer

Droplet precautions require a surgical mask, gloves, and eye protection to prevent exposure to respiratory droplets within 3–6 feet.

Question 5

What is the appropriate response if an electrocardiogram (ECG) lead placed during echocardiography shows sustained ventricular tachycardia?

Accepted Answer

Stop the examination, activate emergency response, and stay with the patient

Answer

Sustained ventricular tachycardia is a life-threatening arrhythmia requiring immediate activation of the emergency response team.
