Chapter 24 : Heart Failure Drugs Questions
Question 1 of 5
When a patient is experiencing digoxin toxicity, which clinical situation would necessitate the use of digoxin immune Fab?
Correct Answer: B,D,E
Rationale: Clinical situations that would require the use of digoxin immune Fab in a patient with digoxin toxicity include serum potassium level above 5 mEq/L, severe sinus bradycardia that does not respond to cardiac pacing, or an overdose of more than 10 mg of digoxin. Seeing colorful halos around lights, nausea, anorexia, fatigue, and headaches are potential adverse effects of digoxin therapy but are not necessarily reasons for digoxin immune Fab treatment.
Question 2 of 5
Which drug classes are considered first-line treatment for heart failure?
Correct Answer: A,B,D
Rationale: ACE inhibitors, ARBs, and certain beta blockers are now considered the first-line treatments for heart failure. Digoxin is used when the first-line treatments are not successful; nesiritide is considered a last-resort treatment.
Question 3 of 5
The medication order for a 5-year-old child reads, -Give digoxin elixir, 15 mcg/kg, PO now. Convert the 15 micrograms to milligrams.
Correct Answer: 0.015 mg
Rationale: 1000 mcg : 1 mg :: 15 mcg : x mg; (1000 * x) = (1 * 15); 1000x = 15; x = 15/1000 = 0.015 mg.
Question 4 of 5
A patient about to receive a morning dose of digoxin has an apical pulse of 50 beats/min. What will the nurse do next?
Correct Answer: D
Rationale: Digoxin doses are held and the prescriber notified if the apical pulse is 60 beats/min or lower or is higher than 100 beats/min. The other options are incorrect.
Question 5 of 5
A patient is taking digoxin and a loop diuretic daily. When the nurse enters the room with the morning medications, the patient states, -I am seeing a funny yellow color around the lights. What is the nurse's next action?
Correct Answer: A
Rationale: Seeing colors around lights is one potential indication of developing digoxin toxicity. If a patient indicates these visual problems, the nurse needs to assess for other signs and symptoms of digoxin toxicity including bradycardia, headache, dizziness, confusion, nausea, and blurred vision, and then notify the prescriber. Administering the drug or withholding the diuretic are incorrect options.
