moderate (4 METs to 6 METS)
poor (<4 METS)

Question 4

____ METs indicate patients with sufficient functional capacity to proceed for surgery

Answer 4

> 4 METs
may proceed for surgery provided patients with cardiac risk factors are properly managed with statin and β-blocker therapy

Question 5

Answer 5

• doesn’t consider severity of planned surgery
• assessment of patient’s medical co-morbidities
• used with other factors (eg, type of surgery, frailty, level of deconditioning), it can be helpful in predicting perioperative risks.
