CET Patient Care & Procedure Assistance 2

Question 1

A patient undergoing an upper endoscopy begins vomiting during the procedure. What is the endoscopy technician's immediate priority?

Accepted Answer

Turn the patient to the left lateral decubitus position and suction the oropharynx

Answer

Positioning the patient left lateral and suctioning the airway prevents aspiration, the most immediate risk during vomiting in endoscopy.

Question 2

Which informed consent principle requires that a patient understand what will happen during a colonoscopy before agreeing to the procedure?

Accepted Answer

Disclosure

Answer

Disclosure requires providing the patient with adequate information about the procedure, risks, benefits, and alternatives before consent is given.

Question 3

During a conscious sedation procedure, the patient's oxygen saturation drops to 88%. What should the technician do first?

Accepted Answer

Apply supplemental oxygen via nasal cannula or face mask

Answer

Applying supplemental oxygen is the first-line intervention for a desaturation event during procedural sedation.

Question 4

An endoscopy technician is assisting with a pediatric flexible sigmoidoscopy. Compared to adult procedures, which adjustment is most important?

Accepted Answer

Using a pediatric scope and reducing insufflation pressure

Answer

Pediatric patients require smaller-caliber scopes and lower insufflation pressures due to their smaller anatomy and greater risk of perforation.

Question 5

What is the purpose of placing a bite block during upper endoscopy?

Accepted Answer

To prevent the patient from biting the endoscope and injuring the mouth

Answer

A bite block protects the endoscope from being bitten and prevents oral injury to the patient during the procedure.
