Which best characterizes this patient's rhythm? - CORRECT ANSWER Unstable SVT SR with *1st degree AV block* on the ECG - CORRECT ANSWER P = ↑1:1; HR = reg. 60-100; PR = *wide > .20*; QRS = narrow; *2nd degree AV block type I* on the ECG - CORRECT ANSWER P↑ > QRS; HR = A. reg. V. irr.; *PR = long, longer, longer...drop!*; QRS = narrow; *2nd degree AV block type II* on the ECG - CORRECT ANSWER P↑ > QRS; HR = reg. 60-100; QRS = narrow/wide; *PR = when related with QRS, it's constant*; *3rd degree AV block* on the ECG - CORRECT ANSWER P↑ > QRS, *unrelated*; HR = A reg. V?; PR = non measurable; *Synchronized Electrical Cardioversion* - CORRECT ANSWER therapeutic dose of electric current to the heart at a *specific moment* in the cardiac cycle, restoring the activity of the electrical conduction system of the heart with a stable patient with a QRS-t complex (100J). *Defibrillation* - CORRECT ANSWER Therapeutic dose of electric current to the heart at a *random moment* (unsynchronized cardioversion) in the cardiac cycle with unstable patient, and is the most effective resuscitation measure for cardiac arrest associated with: V-fib and pulseless V-tach. With the *drop in cardiac output*, a patient may experience the following symptoms (these symptoms occur more frequently with a heart rate >150 beats per minute): - CORRECT ANSWER • Shortness of air (*S*table but serious symptoms) • Palpitation feeling in chest (S) • Dizziness (S) • Rapid breathing (S) • Numbness of body parts (S) • Ongoing chest pain (*U*nstable) • Loss of consciousness (U) The pathway of choice for SVT in the tachycardia algorithm is based on whether the patient is stable or unstable: Unstable patients with *SVT* (w/pulse) are always treated with _____________; - CORRECT ANSWER *Synchronized cardioversion* (the appropriate voltage for cardioverting SVT is 50-100 J); In cycle length of 400 ms (*0.4 s*) is what rate? - CORRECT ANSWER *150 bpm* (60/0.4=150) • Rate > 100 bpm with gradual onset • P to QRS ratio 1:1 - CORRECT ANSWER Tachycardia Which are known as the precordial leads? - CORRECT ANSWER V1-V6 Which rate is equivalent to an interval of 800 ms (*0.8 s*)? - CORRECT ANSWER 60/0.8 = *75 bpm* Which of the following are considered normal durations for the PR and QRS intervals? - CORRECT ANSWER PR = 150 ms; QRS = 80 ms; Which structure accounts for most of the duration of the PR interval? - CORRECT ANSWER AV node The normal glucose level, during fasting, for non-diabetic patients is _______. - CORRECT ANSWER 70-100mg/dL After FAST - CORRECT ANSWER 1) Support ABCs; 2) Apply oxygen to bring above 94% 3) Check LKW; 4) Check blood count, coags, *glucose*; If the CT scan shows *no hemorrhage*, an Acute Ischemic Stroke is probable and *Fibrinolytic Therapy* is recommended after NIHSS screening: T/F - CORRECT ANSWER True Fibrinolytic Therapy is recommended within 3 hrs from stroke onset: T/F - CORRECT ANSWER True If the patient is not a candidate for Fibrinolytic Therapy on the NIH Stroke Scale, administer aspirin and send for a CT scan w/o contrast and obtain ECG: T/F - CORRECT ANSWER True When stroke is suspected, check glucose level: T/F - CORRECT ANSWER True If hemorrhage is present on CT scan, fibrinolytic Therapy is recommended: T/F - CORRECT ANSWER False Possible causes for stroke - CORRECT ANSWER 1) Diabetes; 2) HTN; 3) Hypercholesterolemia; 4) Family History; Hyperglycemia - CORRECT ANSWER blood glucose level >6.0 mmol/L (*>108 mg/dL*),
