  2. I might be able to change from insulin to a pill with metoprolol (Lopressor).
  3. I might need less insulin when I take metoprolol (Lopressor).
  4. I might need more insulin when I take metoprolol (Lopressor).

Question 2

Answer to Question 1

Correct Answer: 3
Rationale: Metoprolol (Lopressor) may enhance the hypoglycemic effects of insulin and oral hypoglycemic agents, so the patient might require less insulin. Metoprolol (Lopressor) may enhance the hypoglycemic effects of insulin and oral hypoglycemic agents, so the patient might require less, not more, insulin. Metoprolol (Lopressor) will not change a diabetic patient's need for insulin; the patient might just require less insulin. The patient will most likely need more frequent blood glucose assessments, as metoprolol (Lopressor) may enhance the hypoglycemic effects of insulin.

Answer to Question 2

Correct Answer: 4
Rationale: Hypokalemia and hypocalcemia can result from an interaction with furosemide (Lasix) and digoxin (Lanoxin), so it will increase a patient's risk for digoxin (Lanoxin) toxicity. Hypercalcemia and hyperkalemia do not result from an interaction with furosemide (Lasix) and digoxin (Lanoxin), so it will not increase the patient's risk for digoxin (Lanoxin) toxicity. Hypermagnesemia and hyponatremia do not result from an interaction with furosemide (Lasix) and digoxin (Lanoxin), so it will not increase the patient's risk for digoxin (Lanoxin) toxicity. Hyponatremia and hyperkalemia do not result from an interaction with furosemide (Lasix) and digoxin (Lanoxin), so it will not increase the patient's risk for digoxin (Lanoxin) toxicity.
