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 - CORRECT 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 - CORRECT 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." - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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 - CORRECT 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
