NSG 318 EXAM 3 WITH 100%
CORRECT ANSWERS 2025/2026
Acute heart failure - correct answers -Heart muscle weakness and enlarges
Loses ability to pump blood adequately
Compensatory mechanisms fail
Lungs and periphery become congested
Right-sided heart failure - correct answers -blood backs up in periphery
Left-sided heart failure - correct answers -blood backs up in lungs
Cardio Megaly - correct answers -enlarged heart (can be caused by chronic HTN)
Nonpharmacologic treatment for Heart Failure - correct answers --Limit salt and
saturated fat intake
-Limit or avoid alcohol intake; stop smoking
-Perform mild exercise
,What's the main use of Digoxin? - correct answers -to decrease workload of the
heart
(does so by inhibiting sodium-potassium ATPase)
How does Digoxin effect the heart muscle? - correct answers --Increases
myocardial contractility
-Increases cardiac output
-Decreases heart rate
-Decreases conduction
When would you use Digoxin with caution? - correct answers -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? - correct answers -Halo effect (blurred or
yellow vision)
Anorexia, vomiting
Antidote for Digoxin - correct answers -Digoxin Immune FAB (digiband)
How might a diuretic and antacid effect someone on Digoxin? - correct answers -
Increases the risk for digitalis toxicity (diuretic)
, Decreases Digoxin absorption (antacid)
Which CAM may increase Digoxin levels and increase the risk of toxicity? - correct
answers -Ginseng (increase levels)
Licorice, aloe, and ephedra (increase risk of toxicity)
When shouldn't you administer Digoxin? - correct answers -When a patients heart
rate is under 60 bpm
Therapeutic level of Digoxin: - correct answers -0.5-1 ng/mL
What does angina indicate? - correct answers -decreased blood flow to the heart
(men can present with crushing pain or like an elephant is on their chest; women
may present with andigestion)
What are the 3 types of antianginal drugs? - correct answers -1. Nitrates
2. Beta blockers
3. Calcium channel blockers
they decrease the hearts need for oxygen
