When displayed by the patient, which symptom would be most indicative to the nurse to withhold a recently prescribed beta-adrenergic blocker?
a. Dizziness
b. Peripheral edema
c. Hyperglycemia
d. Wheezing
ANS: D
Wheezing in a patient taking beta-adrenergic blockers could indicate the adverse effect of bronchial constriction. Dizziness may indicate changes in blood pressure and safety precautions should be taken, but the medication does not have to be stopped. Peripheral edema may indicate cardiovascular problems, but the medication may have been prescribed to help these conditions. It would not warrant stopping the medication. Hyperglycemia may indicate a need for other interventions but would not be a reason to stop the medication.
