Question 1 of 5

When educating a client about to undergo a pacemaker insertion, the nurse explains the normal phases of cardiac muscle tissue. During the repolarization phase, the nurse will stress that membranes must be repolarized before they can be re-excited. Within the cell, the nurse understands that:

A. Potassium channels open while sodium channels close, causing repolarization to the resting state. B. The influx of calcium is the primary stimulus for the repolarization of cardiac tissue. C. Only the electrical activity within the heart will determine when repolarization occurs. D. The cell membranes need to stay calm, resulting in muscle tissue becoming refractory.

Question 2 of 5

A nurse recalls an example of an immune-complex-mediated disease is:

A. Bronchial asthma B. Contact dermatitis C. Serum sickness D. Rheumatoid arthritis

Question 3 of 5

What is the primary action of bisphosphonates when prescribed to a patient with osteoporosis?

A. It inhibits bone resorption, which helps maintain bone density. B. It stimulates new bone formation by increasing osteoblast activity. C. It increases calcium absorption in the intestines, which helps build stronger bones. D. It decreases calcium excretion by the kidneys, helping to maintain bone density.

Question 4 of 5

A patient with a history of osteoporosis is prescribed raloxifene (Evista). What is the primary therapeutic action of this medication?

A. It stimulates the formation of new bone. B. It decreases bone resorption and increases bone density. C. It increases calcium absorption in the intestines. D. It increases the excretion of calcium through the kidneys.

Question 5 of 5

A. A patient who has experienced a spinal cord injury and reports severe, burning pain in his legs. B. A patient who reports severe pain in her hand following a surgery for carpal tunnel syndrome. C.
