The nurse directs an 80-year-old recovering from a fractured pelvis to participate in several isometric exercises to maintain muscle strength, such as:
a. alternately tightening and relaxing of the muscles of the abdomen.
b. lifting the body up off the bed using an overhead trapeze.
c. pushing against the bed to lift the buttocks off the bed a few inches.
d. pressing the sole of the foot against a footboard.
Question 2
Because isometric and isotonic exercises can cause the patient to perform an accidental Valsalva maneuver, the nurse coaches the patient to:
a. hold the breath during an exercise cycle.
b. breathe through the mouth.
c. breathe deeply and rhythmically during an exercise cycle.
d. breathe in through the nose and out through the mouth.
