- Q1Which condition would alert the nurse of the need to use beta-adrenergic blockers cautiously?Cardiac dysrhythmiasRaynaud's PhenomenonEmphysemaHypertension60s
- Q2A 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?“The symptoms will tend to resolve with continued therapy.”“The symptoms are unusual and need to be reported to the healthcare provider immediately.”“The symptoms are typical and indicate that the medication is at a therapeutic level.”“The symptoms are indicative of toxicity.”60s
- Q3What is the primary response to alpha-1–receptor stimulation?Uterine relaxationBronchodilationTachycardiaVasoconstriction30s
- Q4Which category of medications is used for peripheral vascular diseases characterized by excessive vasoconstriction, such as Raynaud’s disease?Adrenergic agentsBeta-adrenergic blocking agentsAlpha-adrenergic blocking agentsCholinergic agents30s
- Q5Why are beta blockers used cautiously in patients with respiratory conditions?They mask the signs and symptoms of acute hypoglycemia.They cause extensive vasodilation and cardiac overloadThey increase hypertensive episodesThey may produce severe bronchoconstriction.30s
- Q6A 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 help you urinate.”“These drugs will assist in lowering your heart rate.”“These drugs inhibit the action of acetylcholine.”“These drugs will decrease your eye pressure.”30s
- Q7Before the initiation of anticholinergic medications, it is important for the nurse to screen patients for which condition?DiabetesClosed-angle glaucomaInfectious diseasesHypertension30s
- Q8Which nerve endings liberate norepinephrineMuscarinicAnticholinergicAdrenergicCholinergic30s
- Q9The autonomic nervous system can be subdivided into which types of adrenergic receptors?Afferent and efferentAgonists and antagonistsAlpha and betaNicotinic and muscarinic30s
- Q10Prior to the administration of metoprolol, a beta-adrenergic blocking agent, which is most important for the nurse to assess?Blood pressureLung soundsUrine outputMental status30s
- Q11A 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.”“This medication should not be discontinued suddenly.”“I may not have my usual symptoms of a hypoglycemic reaction while on this drug.”“This medication may take a few weeks to work.”30s
- Q12An 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?Encourage the patient to decrease water intakeDetermine the therapeutic blood levelWithhold the medicationElevate the patient’s legs30s
- Q13A patient hospitalized in an acute care setting reports to the nurse that since starting on an adrenergic medication, he has been feeling “dizzy and weak.” The most appropriate action for the nurse is to:discontinue the adrenergic blocker.teach the patient to move slowly from standing to sittingmonitor the blood pressure in both the supine and standing positionsimmediately notify the physician.30s
- Q14A long-term care resident is taking an anticholinergic agent. The nurse observes the resident to be disoriented and hallucinating. The priority nursing action is to:provide for resident’s safety.medicate with antianxiety medication.assess blood glucose.report development of alterations to the charge nurse30s
- Q15The nurse is caring for a patient taking a cholinergic agent. When auscultating lung sounds, the nurse notes inspiratory and expiratory wheezing bilaterally. The best action for the nurse to take would be to:reposition the patient.provide the next dose of the cholinergic agent immediatelywithhold the next dose and notify the physicianassess heart rate and blood pressure.30s
