Answer to Question 1

D
Parathormone, or parathyroid hormone, is produced and secreted by the parathyroid glands. Low calcium levels will stimulate release of parathormone, which increases the plasma level of cal-cium. Parathormone acts on the renal tubules to increase the excretion of phosphorus in the urine and to stimulate the reabsorption of calcium. Parathormone also acts on bone, causing the release of calcium from the bone into the bloodstream.

Answer to Question 2

C
Most physicians use an arterial closure device at the puncture site, which enables the patient to be ambulatory within 2 hours after the cardiac catheterization procedure. The patient may be turned to either side. Sandbags were used in the past to prevent bleeding from the puncture site and the patient had to lay flat for several hours. Flexing and extending the legs immediately after the procedure would likely cause bleeding from the site.
