All but d 2. Once the muscarinic receptor on the smooth muscle is stimulated: a. GTP converts int0 cyclic -GMP which results in an increase of free intracellular Ca++. b. ATP converts into cyclic-AMP which triggers protein kinase A to reduce intercellular Ca ++. c. Both happen at once; the result is a balance of intracellular Ca ions 3. The resorcinol and saligenin families of bronchodilators have: a. Rapid onset and prolonged duration of action b. Rapid onset and shorter duration of action c. Slower onset and shorter duration of action d. Slower onset and prolonged duration of action 4. The resorcinol and saligenin families of bronchodilators are: a.

The resorcinol and saligenin families of bronchodilators have: a. More specific action at the Beta II b. More specific action at the Beta I c. Widespread adrenergic action at alpha, Beta I and II receptors 6. The rise of free intercellular Ca ions in the bronchial smooth muscle results in: a. Bronchospasm b. Bronchodilation 7. The catecholamine family of bronchodilators have: a. Rapid onset and prolonged duration of action b. Rapid onset and shorter duration of action c. Slower onset and shorter duration of action d. Slower onset and prolonged duration of action 8. Because epinephrine is known for its tachyphylaxis: a. The drug doses must be given closely together for there to be an effect b. The drug wears off slowly so doses need to be pretty far apart c. The drug is only effective for a couple of treatments d. b and c 9. Your patient has an exacerbation of asthma. You would best give him which drug by subQ shot? a. Racemic epinephrine b. Epinephrine c. Terbutaline sulfate 2/12/201612:13:00 PM Buzbee pharmacology Unit 2 part I page 2 10.

Urinary retention of the receptors are located in the bladder d. A and c e. A and b 13. T/F During CPR, a patient is given epinephrine by IV to restart the heart and to increase the blood pressure by vasodilation. 14. Headache, insomnia, nervousness caused by adrenergic agonists is caused by stimulation of: a. Alpha receptors b. Beta I receptors c. Beta II receptors d.

Cholinergic antagonist d. Xanthines e. Drugs with a combination of a and d 17. Beta I stimulation of the SA node a. raises the heart rate & increases contractility thus increases the cardiac output. b. could just trigger dangerous cardiac arrhythmias. 18.

Racemic epinephrine 2.25% is used to: a. Restart a stopped heart during CPR b. Treat subglottic edema c. Treat asthma d. Prevent wheezing, rather than treat it 21. Metaproterenol 5% is used to: a.

Beta I stimulation of the ventricles could: a. raises the heart rate & increases contractility thus increases the cardiac output. b. could just trigger dangerous cardiac arrhythmias. 25. Terbutaline sulfate is used to: a. Restart a stopped heart during CPR b. Treat subglottic edema c. Treat asthma d. Prevent wheezing, rather than treat it. 26. Albuterol: a. Has only S-isomer b.
