The correct answer is C. continue the test if there is otherwise no reason to believe that the client has reached aerobic. Reaching 85% of age-predicted maximum heart rate during a 1.5-mile run is not itself a termination criterion; the test should continue if no other clinical signs are present.

  • Bterminate the test for safety purposes
  • Ccontinue the test if there is otherwise no reason to believe that the client has reached aerobic
  • Dterminate the test if you continue to observe a steady increase in heart rate with increasing

Why each option

Reaching 85% of age-predicted maximum heart rate during a 1.5-mile run is not itself a termination criterion; the test should continue if no other clinical signs are present.

Acontinue the test until she reaches 100% of her age-predicted heart rate maximum

Requiring a client to reach 100% of age-predicted maximum heart rate is unnecessary and unsafe for a field-based aerobic capacity test, which uses submaximal or maximal self-paced effort rather than a laboratory-controlled maximum.

Bterminate the test for safety purposes

Terminating the test solely because the client reached 85% of age-predicted maximum heart rate is not supported by standard exercise testing guidelines, as this threshold alone does not constitute a safety concern.

Ccontinue the test if there is otherwise no reason to believe that the client has reached aerobicCorrect

Submaximal aerobic field tests like the 1.5-mile run are designed to elicit elevated heart rates, and 85% of age-predicted maximum heart rate is within the expected and acceptable range for this protocol. Termination is indicated by symptoms such as chest pain, dizziness, or pallor - not by a specific heart rate percentage alone in an otherwise healthy client. Continuing the test under these conditions allows for a valid aerobic capacity estimate.

Dterminate the test if you continue to observe a steady increase in heart rate with increasing

A steady increase in heart rate with increasing workload is a normal and expected physiological response to progressive aerobic exercise and is not itself a reason to terminate the test.
