Cardiac NCLEX Questions and Answers 100% Solved| Latest Update Graded A+
Why is slowing the heart rate a good thing when on digoxin? This give the coronary arteries
and ventricles enough time to fill up with blood.
What will happen to cardiac output when on dig? goes up
What will happen to kidney perfusion when on dig? goes up
Would you want to diurese a HF client? yes!
Why can heart failure clients not get whole blood? It's too much fluid, their heart cannot
handle it
What is the normal digoxin level? 0.5-2.0 ng/mL
How do you know the digoxin is working? CO will increase
What are signs and symptoms of dig toxicity? early: anorexia, nausea, vomitting
late: arrhythmias, vision changes
What do you do before administering digoxin? check the apical pulse, hold if less than 60
Why must you check your patients electrolyte status before giving digoxin? hypokalemia +
digoxin = toxicity
What is the action of diuretics in HF? diuresing fluids, therefore decreasing preload
, What time of day do you give diuretics? morning
What type of diet would you like a HF pt to be on? low sodium to decrease fluid retention
Why should HF clients stay away from salt substitutes? contain excessive potassium
What position should any heart patient be in? Elevate HOB
What happens if your heart rate drops below 60? CO decreases
What is the most common complication post op pacemaker? electrode displacement
What is it called when there is no contraction that follows the stimulus with a pacemaker?
loss of capture
What is it called when a pacemaker fires at inappropriate times? failure to sense
What can cause loss of capture, failure to sense or any malfunction with a pacemaker? not
programmed correctly, electrodes dislodged, battery may be depleted
Who is at risk for pulmonary edema? Anyone who is: receiving fluids really fast, very young
or old, has heart or kidney history
What is the brief patho of pulmonary edema? Fluid is backing up into the lungs when the
heart can't move it forward through the body
