Answer to Question 1

A
Feedback:
The correct procedure for venipuncture is to check for presence of a radial pulse. Locate a peripheral vein, apply the tourniquet about 4 to 6 inches above the proposed insertion site, and ask the client alternately to open and close the fist, ending with a closed fist. If a vein is difficult to locate, the nurse should lower the arm below the level of the heart and/or tap or stroke the area, while gently moving away from the heart.

Answer to Question 2

B
Feedback:
Hyperparathyroidism associated with osteomalacia is caused by excess production of parathyroid hormone (PTH). It causes depletion of the serum calcium level. This may lead to skeletal tenderness and weak bones. The depletion of other minerals, such as potassium, sodium, and magnesium, is not associated with hyperparathyroidism associated with osteomalacia.
