Abrupt medication withdrawal may lead to a rebound hypertension.
Which is the pharmacological action of propranolol (Inderal)?

During assessment of a patient diagnosed with pheochromocytoma, the nurse auscultates a blood pressure of 210/110 mm Hg. The nurse would expect to administer which medication?
The nurse understands beta blockers produce which cardiovascular effects?
Negative inotropic, negative chronotropic, and negative dromotropic
What is the priority nursing diagnosis for a patient prescribed metoprolol (Lopressor)?
Risk for decreased cardiac tissue perfusion related to effects of medication
When performing discharge instructions to a patient prescribed metoprolol (Lopressor), which statement by the nurse is correct?
If you take your pulse and it is less than 60 beats/min, hold your medicine and call your health care provider for instructions.
Beta blockers have a negative chronotropic effect and could cause symptomatic bradycardia or heart block. The health care provider should be consulted before administering to a patient with bradycardia
The nurse is caring for a patient with a history of angina and hypertension who is diagnosed with moderate heart failure. The patient's current medication regimen includes digoxin (Lanoxin), furosemide (Lasix), and quinapril (Accupril). Which medication would be most beneficial for the health care provider to add to this patient's treatment plan?
Carvedilol (Coreg), a combined alpha11 and beta blocker, has been shown to slow the progression of heart failure and decrease the frequency of hospitalization in patients with mild to moderate (Class II or III) heart failure. Carvedilol is most commonly added to digoxin, furosemide, and angiotensin-converting enzyme inhibitors when used to treat heart failure.
Beta blockers are used to treat which conditions?
Beta blockers are effective in treating hypertension (secondary to negative inotropic effects), angina pectoris (decreases cardiac workload when decreasing heart rate and contractility), and cardiac dysrhythmias (decreasing heart rate and conductivity). Beta blockers can exacerbate COPD because they block beta22 receptors and subsequent bronchodilation. Raynaud's disease may be treated with alpha, not beta, blockers.
