NSG 318 EXAM 3 QUESTIONS AND
THEIR COMPLETE SOLUTIONS
Acute heart failure
Heart muscle weakness and enlarges
Loses ability to pump blood adequately
Compensatory mechanisms fail
Lungs and periphery become congested
Right-sided heart failure
blood backs up in periphery
Left-sided heart failure
blood backs up in lungs
Cardio Megaly
enlarged heart (can be caused by chronic HTN)
Nonpharmacologic treatment for Heart Failure
-Limit salt and saturated fat intake
-Limit or avoid alcohol intake; stop smoking
-Perform mild exercise
What's the main use of Digoxin?
to decrease workload of the heart
(does so by inhibiting sodium-potassium ATPase)
How does Digoxin effect the heart muscle?
-Increases myocardial contractility
-Increases cardiac output
, -Decreases heart rate
-Decreases conduction
When would you use Digoxin with caution?
If someone has hyper/hypothyroidism or renal/hepatic
dysfunction
As well as with older adults as they probably don't have
complete heart health
Common signs of Digoxin toxicity?
Halo effect (blurred or yellow vision)
Anorexia, vomiting
Antidote for Digoxin
Digoxin Immune FAB (digiband)
How might a diuretic and antacid effect someone on
Digoxin?
Increases the risk for digitalis toxicity (diuretic)
Decreases Digoxin absorption (antacid)
Which CAM may increase Digoxin levels and increase
the risk of toxicity?
Ginseng (increase levels)
Licorice, aloe, and ephedra (increase risk of toxicity)
When shouldn't you administer Digoxin?
When a patients heart rate is under 60 bpm
Therapeutic level of Digoxin:
0.5-1 ng/mL
What does angina indicate?
decreased blood flow to the heart
