15 degrees of knee flexion
90 degrees of knee flexion
During a conference with the physical therapist, a respiratory therapist indicates that the patient has a low expiratory volume. What does this mean?

b. The volume of air in a breath during normal breathing is low
c. The volume of air forcefully expired after a forceful inspiration is low
d. The amount of air expired after a resting expiration is low
d. The amount of air expired after a resting expiration is low
During an evaluation, a 74-year-old woman informs you that she is “taking her heart pill”. The patient does not have her medication with her but states that the medication “slows down my heart rate”. Which of the following is the most probable medication?

A patient is referred to physical therapy with a secondary diagnosis of hypertension. The physician has ordered relaxation training. The therapist first chooses to instruct the patient in the technique of diaphragmatic breathing. Which of the following choices is the correct set of instructions?
Slow breathing rate to (8-12 or 12-16) breaths per minute, (increase/decrease) movement of the abdominal region , and (increase/decrease) movement in the upper chest
Slow breathing rate to 8-12 breaths per minute, INCREASE movement of the abdominal region, and DECREASE movement in the upper chest
Which of the following statements about cardiovascular response to exercise in trained and/or sedentary patients is false?

b. Cardiovascular response to increased workload will increase at the same rate for sedentary patients as it will for trained patients
c. Trained patients will have a longer stroke volume during exercise
d. The sedentary patient will reach anaerobic threshold faster than the trained patient if workloads are equal
b. Cardiovascular response to increased workload will increase at the same rate for sedentary patients as it will for trained patients
A therapist is asked to examine a patient in the intensive care unit. The patient is comatose but breathing independently. During the assessment of range of motion in the right upper extremity, the therapist notices that the patient is breathing unusually. The pattern is an increase in breathing rate and depth followed by brief pauses in breathing. The therapist should notify the appropriate personnel that the patient is exhibiting which of the following patterns?
