QUESTIONS WITH CORRECT
ANSWERS
A patient about to receive his morning dose of digoxin has an apical
pulse of 70 beats per minute. What will the nurse do?
A. Administer the dose.
B. Administer the dose and notify the physician.
C. Check the radial pulse for 1 full minute.
D. Withhold the dose and notify the - ANSWER- A. Administer the
dose.
In assessing a patient before administration of a cardiac glycoside, the
nurse knows that what condition can predispose a patient to digitalis
toxicity?
A. Hypokalemia
B. Hyperkalemia
,C. Hypocalcemia
D. Hypernatremia - ANSWER- A. Hypokalemia; control ventricular
response to atrial fibrillation and a derived from foxglove. Digoxin is
the only available cardiac glycoside---positive inotropic---inhibits
sodium potassium pump (adenosine tripphophatase) Sodium and
calcium rise. Cholinergic stimulation via the vagus nerve of
Parasympathetic nervous system. ---Negative chronotropic---
Negative Dromotropic effect
While assessing a patient who is receiving intravenous digitalis, the
nurse recognizes that the drug has a negative chronotropic effect. How
would this drug effect be evident in the patient?
A. Increased heart rate
B. Decreased heart rate
C. Decreased conduction
D. Increased ectopic beats - ANSWER- B. Decreased heart rate
A patient has been taking digoxin at home but has taken an accidental
overdose and has developed toxicity. He has been admitted to the
telemetry unit where the physician has ordered digoxin immune Fab
(Digibind). The patient asks the nurse why the medication is ordered.
What is the nurse's best response?
A. "It works faster than digoxin."
B. "It is safer than digoxin and can be taken orally."
C. "It helps to convert the irregular heart rhythm to a more normal
rhythm."
,D. "This drug is an antidote to digoxin and will help to lower the blood
levels." - ANSWER- D. "This drug is an antidote to digoxin and will
help to lower the blood levels." (severe bradycardia, advanced heart
block, ventricularr tachycardia, fibrillation, and hyperkalemia);
available in parental form. Clinical signs and symptoms are
monitored NOT serum levels----used for systolic heart failure and
atrial fibrillation.
5. A patient has been placed on a milrinone infusion as part of the
therapy for end-stage heart failure. What risks involved with this drug
will the nurse keep in mind while assessing this patient during the
infusion?
A. Hypertension
B. Hyperkalemia
C. Nausea and vomiting
D. Cardiac dysrhythmias - ANSWER- D. Cardiac dysrhythmias
(contraindictated with ventricular tachycardia, and fibrillation)
used for treatment of atrial fibrillation. Available in Oral and
injection form.
6. A patient with atrial fibrillation was started on digoxin, and 1 week
later a digoxin level was drawn. Which result is within normal
therapeutic levels for digoxin?
A. 0.4 ng/mL
B. 0.7 ng/mL
C. 2.1 ng/mL
, D. 2.6 ng/mL or higher - ANSWER- B. 0.7 ng/mL (normal 0.5 to 2.0
ng/mL
7. When reviewing the list of medications taken by a patient who will be
receiving a new prescription for digoxin, the nurse would be concerned
about which medication that may interact with the digoxin?
A. aspirin
B. acetaminophen (Tylenol)
C. furosemide (Lasix)
D. vitamin K - ANSWER- C. furosemide (Lasix); (loop Diuretics);
numerous ones on page 341
8. The nurse is reviewing discharge teaching for a patient who will be
taking digoxin (Lanoxin) therapy. The patient should be taught to avoid
which foods when taking the digoxin?
A. Leafy green vegetables
B. Dairy products
C. Grapefruit juice
D. Bran muffins - ANSWER- D. Bran muffins
9. In assessing a patient before administration of a cardiac glycoside, the
nurse knows that which lab result can increase the toxicity of the drug?
A. Potassium level 2.8 mEq/L
B. Potassium level 4.9 mEq/L
C. Sodium level 140 mEq/L
