CRNA Quizzes & Trivia

Sympathomimetic stimulants are drugs, which mimic the effects of endogenous agonists of the nervous system. The CRNA Pharm Sympathomimetic Short Review quiz below is set to gauge your understanding on this and more. All the best.

  • 3. 
    Regarding increased acetylcholine, the muscarinic effect on the heart is bradycardia, on the pulmonary system is bronchospasm and increased secretions, and can also cause diffuse EEG activity neurologically.
    • A.

    • B. 

      False

  • 4. 
    Which of the following is decreased during a fight or flight reaction?
    • A. 

      Plasma glucose levels

    • B. 

      Cardiovascular function

    • C. 

      Metabolic function

    • D. 

      Gastrointestinal and genitourinary function

  • 5. 
    The indirect affects of dopamine are due to the release of __________.
  • 6. 
    Beta1 stimulation via epinephrine increases cardiac output, contractility, and heart rate; it therefore _________ myocardial oxygen demand
  • 7. 
    According to Greg's ppt, the continuous infusion dose of epinephrine is 2-20 mcg/min.
    • A. 

      True

    • B. 

      False

  • 8. 
    When using epinephrine, the B2 stimulation causes vasodilation of skeletal muscle and causes _________ diastolic blood pressure.
  • 9. 
    Ephedrine is a catecholamine.
    • A. 

      True

    • B. 

      False

  • 10. 
    What is the preferred vasopressor for obstetric cases?
    • A. 

      Ephedrine

    • B. 

      Epinephrine

    • C. 

      Norepinephrine

    • D. 

      Phenylephrine

  • 11. 
    Dosing for ephedrine is 2.5-10 mg for adults and 0.1 mg/kg for children.
    • A. 

      True

    • B. 

      False

  • 12. 
    With patients on monoamine oxidase inhibitors, they should not receive ________ as norepinephrine is in abundance in the nerve cleft and administration can cause a hypertensive crisis
  • 13. 
    Phenylephrine is associated with tachyphylaxis and reflex bradycardia.
    • A. 

      True

    • B. 

      False

  • 14. 
    All of the following describe phosphodiasterase inhibitors except:
    • A. 

      Positive inotrope

    • B. 

      Vasoconstrictor

    • C. 

      Increase cAMP by preventing breakdown

    • D. 

      Decrease SVR

  • 15. 
    Ephedrine is commonly given as a continuous infusion.
    • A. 

      True

    • B. 

      False

  • 16. 
    Ephedrine's direct action occurs by stimulating adrenergic receptors similar to epinephrine, indirect actions may be due to central stimulation, peripheral postsynaptic norepinephrine release, or inhibition of norepinephrine reuptake
    • A. 

      True

    • B. 

      False

  • 17. 
    Albuterol is commonly used for treatment of ________.
  • 18. 
    _______ is to beta-blockade overdose as narcan is to opioid overdose.  The likely mechanism of action is the increase of cAMP in the myocardium, in effect bypassing the beta-adrenergic second messenger system.
  • 19. 
    Remember when I talked in broad generalities about cAMP and cGMP and in general which one might be considered an up regulator and which one might be considered a down regulator. cAMP = up-regulator, cGMP down-regulator?This is my best guess.  cAMP generally increases contractility and cGMP causes smooth muscle relaxation/vasodilation.
    • A. 

      True

    • B. 

      False
