- A. Potential for causing life-threatening GI bleeds
- B. Increased risk of developing systemic arthritis with prolonged use

A nurse is caring for a client with hyperparathyroidism and notes that the client's serum calcium level is 13 mg/dL. Which medication should the nurse prepare to administer as prescribed to the client?
- A. Calcium chloride
- B. Calcium gluconate
- C. Calcitonin (Miacalcin)
- D. Large doses of vitamin D
Correct Answer: C
Rationale: The normal serum calcium level is 8.6 to 10.0 mg/dL. This client is experiencing hypercalcemia. Calcium gluconate and calcium chloride are medications used for the treatment of tetany, which occurs as a result of acute hypocalcemia. In hypercalcemia, large doses of vitamin D need to be avoided. Calcitonin, a thyroid hormone, decreases the plasma calcium level by inhibiting bone resorption and lowering the serum calcium concentration.
The nurse is preparing to administer an intradermal injection. The nurse would insert the needle at which angle?
- A. 15 degrees
- B. 30 degrees
- C. 45 degrees
- D. 90 degrees
Correct Answer: A
Rationale: When giving an intradermal injection, the needle is inserted bevel up at a 15-degree angle. The nurse would insert the needle at a 90-degree angle for an intramuscular injection or for a patient who is obese and requires a subcutaneous injection. Typically a subcutaneous injection is given at a 45-degree angle.

A client with diabetes mellitus visits a health care clinic. The client's diabetes mellitus previously had been well controlled with glyburide (DiaBeta) daily, but recently the fasting blood glucose level has been 180 to 200 mg/dL. Which medication, if added to the client's regimen, may have contributed to the hyperglycemia?
- A. Prednisone
- B. Phenelzine (Nardil)
- C. Atenolol (Tenormin)
- D. Allopurinol (Zyloprim)
Correct Answer: A
Rationale: Prednisone may decrease the effect of oral hypoglycemics, insulin, diuretics, and potassium supplements. Option 2, a monoamine oxidase inhibitor, and option 3, a β-blocker, have their own intrinsic hypoglycemic activity. Option 4 decreases urinary excretion of sulfonylurea agents, causing increased levels of the oral agents, which can lead to hypoglycemia.
