|
Term
|
Definition
| Constriction of the pupils of the eyes. |
|
|
Term
| Direct-acting cholinergic agonists |
|
Definition
| Drugs that are selective to the muscarinic receptors but are nonspecific because the muscarinic receptors are located in the GI tract, glands, and heart. |
|
|
Term
| Indirect-acting cholinergic agonists |
|
Definition

|
Definition
| Drugs that inhibit the actions of ACh by occupying the ACh receptors |
|
|
Term
| Cholinergic agonists, parasympathomimetics, cholinomimetics, cholinergic stimulants |
|
Definition
| Drugs that stimulate the parasympathetic nervous system are called ____(4 names) because the mimic the parasympathetic neurotransmitter ACh. |
|
|
Term
Muscarinic receptors (stimulate smooth muscle and heart rate)
Nicotinic receptors (affect skeletal muscles) |
|
Definition
| 2 types of cholinergic receptors |
|
|
Term
| Direct-acting cholinergic agonists |
|
Definition
| Act on the receptors to activate a tissue response. |
|
|
Term
| Indirect-acting cholinergic agonists |
|
Definition
| Inhibit the action of the enzyme cholinesterase (ChE) |
|
|
Term
|
Definition
| The leaking of fluid from a blood vessel into the surrounding tissues, as in the case of an infiltrated intravenous infusion. |
|
|
Term
|
Definition
| The chemical attraction of a substance to lipid or fat molecules |
|
|
Term
|
Definition
| Are alpha2 receptors inhibitory or stimulatory |
|
|
Term
| Beta-1 adrenergic receptors |
|
Definition
| Receptors that are located primarily in the heart |
|
|
Term
| Beta-2 adrenergic receptors |
|
Definition
| receptors that are located primarily on the smooth muscles of the bronchioles and blood vessels |
|
|
Term
|
Definition
| A tumor that forms on the adrenal gland on top of the kidney and secretes norepinephrine, thus causing SNS stimulation. Alpha-blockers may prevent hypertension in patients who have this condition. |
|
|
Term
|
Definition
| When drugs extravasate, or leak out of the blood vessel into the surround tissue, they cause vasoconstriction and ultimately _____________. |
|
|
Term
|
Definition
| _____ can reverse the potent vasoconstriction and restore blood flow to the ischemic tissue, preventing necrosis. |
|
|
Term
|
Definition
| Used for control of seizures |
|
|
Term
| False (Drugs with intrinsic sympathomimetic activity block beta-adrenergic receptors, but also partially stimulate them) |
|
Definition
| True or false: Drugs with intrinsic sympathomimetic activity stimulate beta-adrenergic receptors. |
|
|
Term
| Beta-1 receptors on the surface of the heart |
|
Definition
| Cardioselective beta1-blockers block which receptors and where are they located? |
|
|
Term
|
Definition
| Production of glucose from glycogen -- catecholamines promote this. |
|
|
Term
|
Definition
| Which blockers are considered to be cardioselective? |
|
|
Term
| False (beta-blockers protect the heart from being stimulated by catecholamines) |
|
Definition
| True or false: alpha-blockers protect the heart from being stimulated by catecholamines. |
|
|
Term
|
Definition
| True or false: Because of their lipophilicity, some beta-blockers can easily gain entry into the central nervous system and are used to treat migraine headaches. |
|
|
Term
|
Definition
| True or false: The patient's prescriber should be notified if the patient shows an increase of 2+ pounds in a 24 hour period or 5+ pounds within 1 week. |
|
|
Term
|
Definition
| The nurse discovers that the intravenous infusion of a patient who has been receiving an intravenous vasopressor has infiltrated. The nurse will expect which drug to be used to reverse the effects of the vasopressor in the infiltrated area? A. Phentolamine B. prazosin (Minipress) C. ergotamine D. metoprolol (Lopressor) |
|
|
Term
| A. vasodilation, B. decreased blood pressure, and D. Constriction of the pupil |
|
Definition
| Adrenergic blockade at the alpha-adrenergic receptors leads to which of the following effects? A. Vasodilation B. Decreased blood pressure C. Increased blood pressure D. Constriction of the pupil E. Tachycardia |
