= Phenylephrine

72- Which of the following sympathomimetics is preferable for the emergency therapy of cardiogenic shock?
~ Epinephrine

= Dobutamine

~ Isoproterenol
~ Methoxamine
73- Which of the following sympathomimetics is related to short-acting topical decongestant agents?
~ Xylometazoline
~ Terbutaline

= Phenylephrine

~ Norepinephrine
74- Indicate the long-acting topical decongestant agents:
~ Epinephrine
~ Norepinephrine
~ Phenylephrine

= Xylometazoline

75- Which of the following topical decongestant agents is an alfa₂-selective agonist?
~ Phenylephrine

= Xylometazoline

~ Ephedrine
~ Epinephrine
76- Indicate the sympathomimetic, which may be useful in the emergency management of cardiac arrest:
~ Methoxamine
~ Phenylephrine

= Epinephrine

77- Which of the following agents is a beta₂–selective antagonist?
~ Tolazolin
~ Pindolol
~ Ergotamin

= Butoxamine

78- Indicate the beta adrenoreceptor antagonist, which has partial beta–agonist activity:
~ Propranolol
~ Metoprolol

= Pindolol

~ Betaxolol
79- Which of the following drugs is a reversible nonselective alfa, beta antagonist?

= Labetalol

~ Phentolamine
~ Metoprolol
~ Propranolol
80- Indicate the indirect-acting adrenoreceptor blocking drug:
~ Tolazoline

= Reserpine

~ Carvedilol
~ Prazosin
81- The principal mechanism of action of adrenoreceptor antagonists is:

= Reversible or irreversible interaction with adrenoreceptors

~ Depletion of the storage of catecholamines
~ Blockade of the amine reuptake pumps
~ Nonselective MAO inhibition
82- Characteristics of alfa-receptor antagonists include all of the following EXCEPT:
~ They cause a fall in peripheral resistance and blood pressure
~ They cause epinephrine reversal (convert a pressor response to a depressor response)
