NURS 114 - Final Exam questions with correct
answers
characteristics of A fib Correct Answer-No P wave; irregular rhythm,
irregular pattern; very fast rate (350-600 atrial beats/minute)
main fn of DMARDs and 2 types Correct Answer-decrease
inflammation
methotrexate and hydroxychloroquine
risks/sxs associated with A fib Correct Answer-low CO; arf thrombus &
stroke bc heart is quivering not actually pumping
drugs for A fib Correct Answer-Amiodarone - regulates rhythm (Ami
won't turn One unless we regulate her rhythm)
Digoxin (do not give if HR < 60) - regulates rhythm (A fIb - dIg)
Anti-coag (warfarin, heparin) - dt thrombus risk
CCB (-pines, diltiazem, verapamil) - relaxes the
heart muscle
B-blockers(-lols) - decrease HR
,whats Dig toxicity Correct Answer-anorexia, NV, fatigue, HA, visual
changes, depression monitor K while giving Dig
What level should you monitor while taking Dig Correct Answer-
potassium
how does too much potassium effect Dig Correct Answer-Too much
potassium can cause digoxin not to be effective/therapeutic
how does too little potassium effect Dig Correct Answer-Too little
potassium can cause digoxin to be TOO effective causing toxicity
Sx for a fib Correct Answer-Cardioversion, ablation
how can you describe A flutter Correct Answer-Sawtooth-shaped flutter
waves
what is A flutter characterized by Correct Answer-No P waves; regular
pattern, irregular rhythm; very fast atrial rate
sxs/ risks when you have a flutter Correct Answer-Low CO; arf
thrombus & stroke
drugs for a flutter Correct Answer-Amiodarone - to maintain nL rhythm
i want ami to stay 1 forever
,Anti-coag (warfarin, heparin) - dt thrombus risk
CCB (-pines, diltiazem) - relaxes the heart muscle
B-blockers(-lols) - decrease HR
sx for a flutter Correct Answer-Cardioversion, ablation
how would you describe SVT Correct Answer-regular rhythm, high rate
(150-220 bpm)
basically tachycardia, just rate above 150
sxs of having SVT Correct Answer-Low CO; low BP; CP & dyspnea
drugs for SVT Correct Answer-#1: IV adenosine - reduce HR (give
rapidly, follow with flush) (drink gator*ADE* to cool down and
*decrease HR* .......or.... I want to slow down on my sinning)
Digoxin - decreases HR (monitor potassium)
Anti-coag (warfarin, heparin) - dt thrombus risk
, CCB (-pines, diltiazem) - relaxes the heart muscle
B-blockers(-lols) - decrease HR
how can you describe bradycardia Correct Answer-P wave present,
regular rhythm, slow rate (< 60 bpm)
what should you do FIRST with a brady pt? Correct Answer-ASK if this
is normal for them.. if it is and they are asymptomatic tx isnt needed
sxs of bradycardia Correct Answer-Fatigue, dizzy, CP, syncope,
confusion, SOB, low BP, pale/cool skin
drugs for bradycardia Correct Answer-IF SYMPTOMATIC... IV
aTrOPine (causes HR to get to the *TOP*)
describe tachycardia Correct Answer-P wave present, regular rhythm,
fast rate (101-149 bpm)
what can cause tachycardia Correct Answer-stressors, exercise, fever,
pain, low BP, low volume, low O2, MI, HF, fear
sxs of tachycardia Correct Answer-Dizzy, SOB, low BP, CP → like
when you're running outside and it's hot
