What instruction should the nurse give a diabetic patient on insulin when propranolol is prescribed?
1. You need to increase your insulin to allow for the additive effects of the propranolol.
2. Propranolol may potentiate the effects of the insulin, so the dose should be reduced.
3. Propranolol has no effects on diabetes or on insulin requirements.
4. Propranolol may mask signs of hypoglycemia. Use signs other than rapid heart rate to know when your glucose is too low.
