Pharmacological and Parenteral TherapiesQuestion 497 of 2368

A client with diabetes mellitus starts metoprolol. Which nursing action is most important?

  1. Hold the drug if blood glucose is above 200 mg/dL
  2. Teach the client that the drug raises blood glucose for several hours
  3. Monitor blood glucose closely because the drug can mask signs of hypoglycemia
  4. Check urine ketones before each dose
Show answer

Correct answer: Monitor blood glucose closely because the drug can mask signs of hypoglycemia

Beta-blockers hide the usual warning signs of low blood sugar, so glucose is checked more often.
