VT Patient Care & Safety 2

Question 1

A patient with a latex allergy is scheduled for a vascular ultrasound. Which action is most important before beginning the exam?

Accepted Answer

Use only latex-free gloves and gel applicators

Answer

Latex-free equipment must be used for all patient contact to prevent an allergic or anaphylactic reaction.

Question 2

During a lower extremity venous duplex exam, a patient reports sudden chest pain and shortness of breath. What should the vascular technologist do first?

Accepted Answer

Stop the exam and activate the emergency response system

Answer

Acute chest pain and dyspnea may indicate pulmonary embolism; immediate emergency activation takes priority over completing the scan.

Question 3

Which infection control measure is most effective in preventing healthcare-associated infections between vascular ultrasound patients?

Accepted Answer

Cleaning the transducer with an approved disinfectant between patients

Answer

Transducer disinfection with an EPA-registered, intermediate-level disinfectant is the primary measure to prevent cross-contamination.

Question 4

A patient receiving anticoagulation therapy requires a compression maneuver during venous duplex imaging. What is the primary safety concern?

Accepted Answer

The maneuver may dislodge a thrombus and cause embolism

Answer

Aggressive compression over a suspected acute thrombus can dislodge it, potentially causing pulmonary embolism.

Question 5

Before performing a treadmill exercise test for arterial insufficiency evaluation, which patient history finding is an absolute contraindication?

Accepted Answer

Recent myocardial infarction within the past 4 weeks

Answer

Recent MI is an absolute contraindication to exercise stress testing due to the risk of fatal arrhythmia or reinfarction.
