Beta Blockers Quiz

Beta blocker with peripheral vasodilator action is:

• Carvedilol

• Propanolol

• Atenolol

• Acebutolol

In a patient Kishore having hypertension, propranolol was given. Though the drug controlled hypertension but it reduced resting heart rate to 50/min. Which of the following β blockers can be used in this patient as an effective substitute which does not cause bradycardia?

• Pindolol

• Labetalol

• Bisoprolol

• Atenolol

Propanolol is contraindicated in diabetes mellitus because it:

• Causes hyperglycemia

• Causes seizures

• Masks the hypoglycemic symptoms

• Causes hypotension

Tamsulosin, a competitive αadrenoceptor antagonist has affinity for which of the following receptors?

• α1A

• α1D

• All the above

• None of the above

Ideal drug employed in the preoperative preparation for surgical excision of pheochromocytoma is:

• Atenolol

• Phenoxybenzamine

• Reserpine

• Clonidine

Which of the following is not a cardioselective β-blocker:

• Acebutol

• Atenolol

• Pindolol

• Metoprolol

Drug of choice for bradycardia due to beta blocker overdose is:

• Atropine

• Dopamine

• Adrenaline

• Isoprenaline

The nonselective α adrenergic blockers produce the following actions except:

• Postural hypotension

• Bradycardia

• Miosis

• Inhibition of ejaculation

The bladder trigone and prostatic muscles are relaxed by:

• Adrenergic α1 agonists

• Adrenergic α1 antagonists

• Adrenergic α2 agonists

• Adrenergic α2 antagonists

The primary reason for preferring phentolamine as the α adrenergic blocker for performing diagnostic test for pheochromocytoma is:

• It produces rapid and short lasting α-adrenergic blockade

• It equally blocks α1 and α2 adrenoceptors

• It is the most potent α blocker

• It has no additional β adrenergic blocking property
