View Attempt 1 of 2 Title: Kee Chap 18 (7th ed) Started: November 14, 2011 11:10 AM Submitte d: November 14, 2011 11:15 AM Time spent: 00:04:44 Total score: 24/25 = 96% Total score adjusted by 0.0 Maximum possible score: 25 1. Drugs that mimic the effect of norepinephrine are called: Student Response Value Feedback A. sympathomimetics, or adrenergic drugs 100% B. sympatholytics, or adrenergic drugs C. sympathomimetics, or adrenergic blockers D. sympatholytics, or adrenergic blockers General Feedback: This is the definition of sympathomimetics, or adrenergic drugs. Score: 1/1 2. When stimulating the beta 1 -adrenergic receptors, the response is: Student Response Value Feedback A. increased blood pressure B. decreased blood pressure C. increased pulse rate 100% D. decreased pulse rate General Feedback: Beta 1 receptors stimulate the heart rate. Score: 1/1

3. The adrenergic receptor that causes bronchodilation when stimulated is: Student Response Value Feedback A. alpha 1 B. alpha 2 C. beta 1 D. beta 2 100% General Feedback: receptors are responsible for bronchodilation. Score: 1/1 4. The adrenergic receptor that causes the greatest increase in blood pressure is: Student Response Value Feedback A. alpha 1 B. alpha 2 0% C. beta 1 D. beta 2 General Feedback: These receptors cause vascular constriction, which increases blood pressure Score: 0/1 5. The general sympathetic responses to adrenergic drugs include: Student Response Value Feedback A. constricting bronchioles and gastrointestinal smooth muscles B. decreasing heart rate and dilating blood vessels

Student Response Value Feedback C. increasing heart rate and constricting blood vessels 100% D. dilating bronchioles and decreasing heart rate General Feedback: These changes represent the "fight or flight" sympathetic responses. Score: 1/1 6. The sympathomimetic drugs that stimulate adrenergic receptors are classified into three categories: direct acting, indirect acting, and mixed acting. An example of a mixed-acting sympathomimetic is: Student Response Value Feedback A. ephedrine 100% B. epinephrine C. norepinephrine D. dobutamine General Feedback: Ephedrine stimulates the release of norepinephrine and directly stimulates alpha and beta receptors, so it is a mixed-acting agent. Score: 1/1 7. The mixed-acting sympathomimetics act by: Student Response Value Feedback A. stimulating the adrenergic receptor sites and inhibiting the release of norepinephrine B. stimulating the adrenergic receptor sites and stimulating the release of norepinephrine 100% C. inhibiting the adrenergic receptor sites and inhibiting the release of norepinephrine D. inhibiting the adrenergic receptor sites and stimulating the
