b. 0.5 to 2.0 ng/mL - ANSWER A newly admitted client takes digoxin 0.25 mg/day. The nurse knows that which is the serum therapeutic range for digoxin? a. 0.1 to 1.5 ng/mL b. 0.5 to 2.0 ng/mL c. 1.0 to 2.5 ng/mL d. 2.0 to 4.0 ng/mL a. It is in the high (elevated) range. - ANSWER The client's serum digoxin level is 3.0 ng/mL. What does the nurse know about this serum digoxin level? a. It is in the high (elevated) range. b. It is in the low (decreased) range. c. It is within the normal range. d. It is in the low average range. d. Pulse below 60 beats/min and irregular rate - ANSWER The nurse is assessing the client for possible evidence of digitalis toxicity.

Pulse greater than 60 beats/min and irregular rate d. Pulse below 60 beats/min and irregular rate a. Increase the serum digoxin sensitivity level - ANSWER The client is also taking a diuretic that decreases her potassium level. The nurse expects that a low potassium level (hypokalemia) could have what effect on the digoxin? a. Increase the serum digoxin sensitivity level b. Decrease the serum digoxin sensitivity level c. Not have any effect on the serum digoxin sensitivity level d. Cause a low average serum digoxin sensitivity level b. Headaches - ANSWER When a client first takes a nitrate, the nurse expects which symptom that often occurs? a. Nausea and vomiting b. Headaches c. Stomach cramps d. Irregular pulse rate c. Decrease heart rate and decrease myocardial contractility. - ANSWER The nurse acknowledges that beta blockers are as effective as antianginals because they do what? a. Increase oxygen to the systemic circulation. b. Maintain heart rate and blood pressure. c. Decrease heart rate and decrease myocardial contractility. d. Decrease heart rate and increase myocardial contractility. b. The beta blocker should NOT be abruptly stopped; the dose should be tapered down. - ANSWER The health care provider is planning to discontinue a client's beta blocker. What instruction should the nurse give the client regarding the beta blocker? a. The beta blocker should be abruptly stopped when another cardiac drug is prescribed. b. The beta blocker should NOT be abruptly stopped; the dose should be tapered down. c. The beta blocker dose should be maintained while taking another antianginal drug. d. Half the beta blocker dose should be taken for the next several weeks. c. To block the beta1-adrenergic receptors in the cardiac tissues - ANSWER The beta blocker acebutolol (Sectral) is prescribed for dysrhythmias. The nurse knows that what is the primary purpose of the drug? a. To increase the beta1 and beta2 receptors in the cardiac tissues b. To increase the flow of oxygen to the cardiac tissues c. To block the beta1-adrenergic receptors in the cardiac tissues d. To block the beta2-adrenergic receptors in the cardiac tissues a. "Apply the patch to a nonhairy area of the upper torso or arm." - ANSWER A client is to be discharged home with a transdermal nitroglycerin patch. Which instruction will the nurse include in the client's teaching plan? a. "Apply the patch to a nonhairy area of the upper torso or arm." b. "Apply the patch to the same site each day." c.
