What are the signs and symptoms of left sided heart failure?
*DROWNING -ANSWER-Dyspnea, crackles, orthopnea, weakness,
nocturnal paroxysmal dyspnea, increased hr, nagging cough, gaining
weight
What are the signs and symptoms of right sided heart failure?
*SWELLING -ANSWER-swelling of legs and hands, weight gain,
edema (pitting), large neck (jvd), lethargy, irregular heart rate,
nocturia, girth (ascites); gi distress and ascites
How is heart failure diagnoses? -ANSWER-BNP, chest X-ray and
echocardiogram
Nursing interventions for heart failure -ANSWER-Strict I/O, daily
weight (report 2-3lb in week), diet restrictions (low sodium, low fat, low
cholesterol), elevate HOB (semi-fowlers)
What are the risk factors for left sided heart failure? -ANSWER-
Hypertension, obesity, hx of mi, substance abuse (cocaine), diabetes
What are the risk factors for right sided heart failure? -ANSWER-Left
ventricular failure, right mi, pulmonary hypertension, copd, acute
respiratory distress
,What is the treatment for heart failure? -ANSWER-Enalapril, Valsartan
and furosemide/bumetanide
patient education for heart failure? *MAWDS -ANSWER-Meds,
activity, weight (daily - 3 to 5lb a week), diet (2-3g sodium), symptoms
What does a normal sinus rhythm include? -ANSWER-P, QRS, T
What is the measurement for a PR interval? -ANSWER-0.12 - 0.2
What is the measurement for a QRS complex? -ANSWER-0.06 - 0.12
What is the measurement for a QT interval? -ANSWER-<0.40
seconds
A widened QRS complex could mean what? -ANSWER-PVCs,
electrolyte imbalance and/or drug toxicity
Define sinus Brady -ANSWER-Regular sinus rhythm but at a rate
lower than 60.
Define sinus tachy -ANSWER-Regular sinus rhythm but at a faster
rate more than 100.
What are causes of sinus Brady? -ANSWER-Sleep, athletic,
hypothyroidism, vagal stimulation, medications (CCB, BB)
What is the treatment of sinus Brady? -ANSWER-Correct underlying
cause, increase the hr to normal
, What are causes of sinus tachy? -ANSWER-Blood loss, fever,
exercise, dehydration, medications (stimulants, illicit drugs, epi), heart
failure, hyperthyroidism
What is the treatment of sinus tachy? -ANSWER-Identify underlying
cause, decrease the hr to normal
Define ventricular tachycardia -ANSWER-Irregular waves; ventricles
are quivering; no contraction or cardiac output which can be fatal
Causes of v-tach -ANSWER-MI, electrolyte imbalance, dig toxicity,
stimulants
Signs and symptoms of v-tach -ANSWER-Pt is awake, chest pain,
lethargy, anxiety, syncope, palpitations
How to treat v-tach if patient has a pulse? -ANSWER-Oxygen,
antidysrhythmics (amioderone stabilizes hr)
How to treat v-tach in a patient with no pulse? -ANSWER-CPR,
defibrillation, drug therapy (epi, amioderone)
Untreated v-tach can lead to what? -ANSWER-Ventricular fibrillation
which can lead to death
Define ventricular fibrillation -ANSWER-Rapid, disorganized pattern of
electrical activity; no visible p, QRS, or t waves. No rate
What are causes of v-fib? -ANSWER-Cardiac injury, medication
toxicity, electrolyte imbalance, untreated v-tach
