Answer to Question 1

A
A. Clients doing isometric exercises should be taught to exhale while exerting effort. Many persons hold their breath (Valsalva maneuver), which increases intrathoracic pressure, causing a decrease in venous return to heart.
B and D. Client will gradually increase number of exercise repetitions.
C. Hold muscles tightly contracted for 5 to 15 seconds and then relax completely for several seconds.

Answer to Question 2

C
Some specimens have special collection requirements before or after specimen collection, for example, for lactic acid levels, do not use a tourniquet. For cryoglobulin levels, use pre-warmed test tubes. For ammonia and ionized calcium levels, place the tube in ice for delivery to the laboratory. For vitamin levels, avoid exposure of the test tube to light.
