Which instructions given by the nurse will assist a patient to cope with the common adverse effects of anticholinergic medications?
"Increase fluids daily." "Suck on candy or ice chips."
Which condition would alert the nurse of the need to use beta-adrenergic blockers cautiously?
Emphysema
Which body functions are controlled by the autonomic nervous system?
Blood pressure, skeletal muscle contraction, GI secretion, body temperature, urination
Which are indications for the use of anticholinergic agents?
bradycardia, Parkinson's disease, preparation for surgery
A patient with a history of type 1 diabetes after myocardial infarction has been placed on a beta-adrenergic blocking agent. Which statement by the patient indicates a need for further teaching?
"This medication lowers my blood pressure by helping me get rid of fluid."
Which adverse effects are common when a patient is receiving a cholinergic agent?
nausea, dizziness, bradycardia
Which category of medications is used for peripheral vascular diseases characterized by excessive vasoconstriction, such as Raynaud's disease?
Alpha-adrenergic blocking agents
Which nerve endings liberate norepinephrine?
Adrenergic
The autonomic nervous system can be subdivided into which types of adrenergic receptors?
Alpha and beta
Prior to the administration of metoprolol, a beta-adrenergic blocking agents, which is most important for the nurse to assess?
Blood pressure
Before the initiation of anticholinergic medications, it is important for the nurse to screen patients for which condition?
Closed-angle glaucoma
Which are examples of neurotransmitters?
Gamma amino-butyric, acetylcholine, serotonin, histamine, epinephrine
A patient with Parkinson's disease asks the nurse why anticholinergics are used in the treatment. Which response by the nurse is most accurate?
These drugs inhibit the action of acetylcholine.
Which statements are true about efferent nerves?
They leave the CNS to carry impulses to other body parts. They are part of the peripheral nervous system. They transmit signals that control contractions of smooth and skeletal muscle. They transmit signals that control contractions of some glandular secretions.
Why are beta blockers used cautiously in patients with respiratory conditions?
They may produce severe bronchoconstriction.
What is the primary response to alpha-1 receptor stimulation?
Vasoconstriction (of blood vessels)
An older adult patient is to receive atenolol, a beta-adrenergic blocking agent. Prior to administration of the drug, the nurse assesses an apical pulse rate of 58 and notes ankle edema. Which action will the nurse take first?
Withhold the medication.
A patient with chronic obstructive pulmonary disease (COPD) reports having insomnia and a racing heart after starting terbutaline therapy. Which explanation by the nurse is most accurate?
