CARDIO - METS

One metabolic equivalent (MET) is equal to: a. 3.5 ml O2/kg/min b. 5.0 ml O2/kg/min c. 7.5 ml O2/kg/min d. 10 ml O2/kg/min

A 1 metabolic equivalent (MET) is equal to 3.5 ml O2/kg/min. A MET represents the basic systemic requirement at rest. Exercise activity can be clinically measured in METs as a comparison to resting energy requirements.

Which metabolic equivalent level is most consistent with walking on a treadmill at 3 miles per hour? a. 1 MET b. 3 METs c. 5 METs d. 7 METs

B 1 MET is the energy expended while sitting quietly (3.5 mLO2/kg/min or 1 kcal/kg/h).

Which level of exercise intensity would be the most appropriate for a patient who is nearing discharge from inpatient cardiac rehabilitation? a. 1 b. 3 c. 5 d. 7

B A patient who is in a Phase I cardiac rehabilitation (i.e., inpatient) program is typically exercising at an intensity of 1-4 METs. As they are nearing discharge from their inpatient stay, they should be exercising at an intensity of 3-4 METs, which may include activities such as walking in the hallway and climbing up and down a flight of stairs.

The first stage of the Bruce protocol requires roughly how many metabolic equivalents (METs)? a. 1 b. 5 c. 10 d. 15

B The first stage of the Bruce protocol requires 5 METs. The Bruce protocol is a screening test for coronary artery disease. It is a multi-staged exercise test that gradually increases in the percent grade of a treadmill and speed thereby increasing METs at each of the 7 levels. The test stops when the patient can no longer continue and is scored according to time.

When calculating energy expenditure using metabolic equivalents, which of the following variables must be considered? a. height and weight of the patient b. height of the patient and duration of activity c. weight of the patient and duration of activity d. age of the patient and duration of activity

C One metabolic equivalent is equal to 3.5 milliliters of oxygen per kilogram of body weight per minute. Therefore, when calculating energy expenditure, both the patient's weight and the duration of the activity would need to be considered.

The primary use of metabolic equivalents for therapists is: a. preserve patient safety during exercise b. monitor response to exercise c. prescribe exercise intensity d. quantify heart rate response

C One metabolic equivalent is the amount of oxygen consumed at rest and is equal to approximately 3.5 milliliters of oxygen per kilogram of body weight per minute. This measure allows therapists to describe the energy requirements of an activity as a multiple of the metabolic rate.

What standardized measurement refers to the amount of oxygen consumed at rest by the average person? a. basal metabolic rate b. resting metabolic rate c. metabolic equivalent d. rate of oxygen consumption

C One metabolic equivalent is the amount of oxygen consumed at rest and is equal to approximately 3.5 milliliters of oxygen per kilogram of body weight per minute. This measure allows therapists to describe the energy requirements of an activity as a multiple of the metabolic rate.

Which of the following household activities would have the lowest metabolic equivalent (MET) value? a. lawn mowing b. vacuuming c. gardening d. cooking

D Metabolic equivalents allow health care providers to describe the energy requirements of an activity as a multiple of the metabolic rate. The MET values are as follows: cooking = 2.0-3.0 METs, vacuuming = 3.0-3.5 METs, gardening = 3.0-4.0 METs, and lawn mowing = 5.5 METs.

Which activity would require the greatest metabolic equivalents (METs) value to complete? a. walking 4MPH b. sleeping c. general house work d. jogging 10 minute mile

D Metabolic equivalents allow therapists to describe the energy requirements of an activity as a multiple of the metabolic rate. Jogging a 10 minute mile is equivalent to approximately 10 METs. The remaining options would require significantly less METs.

How many milliliters of oxygen per kilogram per minute is an individual consuming if they are engaging in an activity that is described as two metabolic equivalents? a. 2.0 b. 4.0 c. 6.0 d. 7.0

D One metabolic equivalent is the amount of oxygen consumed at rest and is equal to approximately 3.5 milliliters of oxygen per kilogram of body weight per minute. As a result, an activity that is two metabolic equivalents would be consistent with 7.0 mL O2/kg/minute.
