Which medication should the nurse prepare to administer as prescribed to the client? 1. Calcium chloride 2. Calcium gluconate 3. Calcitonin (Miacalcin) 4. Large doses of vitamin D: 3. Calcitonin (Miacalcin) Rationale: The no rmal se rum calcium l evel is 8.6 to 10.0 mg/dL. This client is experiencing hypercalcemia. Calcium gluconate and calcium chlo ride are medications used for the treatment of teta ny, which occurs as a result of acute hypocalcemia. In hypercalcemia, large doses of vitamin D need to be avoided. Calcitonin, a t hyroid hormone, decreases the plasma calcium l evel by inhibiting bone reso rption and lowering the se rum calcium concent ration. 2. 2.)

Clients receiving this treatment should be monitored for signs of an acid-base imbalance (hyperventilation). If this occur s, the medication should be disconti nued for 1 to 2 d ays. Options 3 and 4 desc ribe local rather than systemic ef fects. An el evated blood pressure m ay be expected from the pain that occurs with a burn injury. https://www.stuvia.com/ 7. 7.)
