Q

What blood pressure reading requires deferring
dental treatment and directing patient to their primary
care provider or the ER?

A

The day of surgery

8
Q

What type of procedure can you perform if the INR is in the 2.0-3.5 range?

Q

Gauging a patient’s ability to perform normalphysical activity is gauging their what?

Functional capacity

19
Q

The Metabolic Equivalents of Tasks (METs), which isna method to determine a person’s functional capacity, quantifies what?

A

The body’s use of oxygen

20
Q

A MET is equivalent to what with respect to oxygen?

A

MET is a unit of oxygen consumption

1 MET = 3.5 mL of O2/kg of body wt/minute at rest
