ANSWERS
Normal Length for PR, QRS, and QT intervals. - CORRECT ANSWER PR 0.12-0.20
sec, QRS 0.08-0.12 sec, and QT interval less than or = to 450 ms or half the R-R interval
Big box on ECG readings = ___ seconds? - CORRECT ANSWER 0.20 seconds
Little boxes on ECG readings = ____ seconds? - CORRECT ANSWER 0.04 seconds
The mA that achieves capture is the _______ _________ - CORRECT
ANSWER pacing threshold
Defibrillation energy settings (biphasic and monophasic) - CORRECT
ANSWER biphasic 120-200 j and monophasic 360 j
Synchronized Cardioversion energy settings for SVT or aflutter, for afib, and for
monomorphic VT (biphasic and monophasic) - CORRECT ANSWER SVT or aflutter-
biphasic 50-100 j & monophasic 200 j
Afib-biphasic 120-200 j & monophasic 200 j
Monomorphic VT-biphasic 100 j & monophasic 100 j
Vtach treatment - CORRECT ANSWER Synchronized cardioversion and
Antiarrhythmic such as Amiodarone (150-300 mg) and/or lidocaine
Vfib treatment - CORRECT ANSWER Defibrillation also can load them up with
Amiodarone
, SVT treatment - CORRECT ANSWER Vasovagal maneuvers, carotid massage,
Adenosine (if BP is good) 6 mg for first dose and then 12 mg for the second dose, or
synchronized cardioversion
Torsades treatment - CORRECT ANSWER Synchronized cardioverison (if regular) or
defibrillation (if irregular) and administer Mg (treating underlying cause)
Anatomical location of Cardiac Assessment Landmarks - CORRECT ANSWER
Pulse pressure calculation - CORRECT ANSWER Difference between the systolic and
diastolic pressure for example 120/60 the pulse pressure is 60!
Cardiac output normal values - CORRECT ANSWER 4-8 Liters per minute (formula is
Stroke Volume x Heart Rate)
Cardiac Index normal values - CORRECT ANSWER 2.5-4 L/min/m2 (formula is
Cardiac output divided by Body Surface Area aka need ht and wt)
Central Venous Pressure or Right Atrial Pressure normal values - CORRECT
ANSWER 2-6 mmHg or 2-8 cm H2O
Pulmonary Arterial Pressure (PAP) normal values - CORRECT ANSWER Pulmonary
Artery Systolic (PAS) 15-30 mmHg
Pulmonary Artery Diastolic (PAD) 5-15 mmHg
Pulmonary Artery Mean (PAM) 9-18 mmHg
Pulmonary Artery Occlusion Pressure (PAOP) AKA Wedge normal values - CORRECT
ANSWER Similar to CVP or RAP and the diastolic pulmonary artery pressure will
reflect this value closely... PAOP 6-12 mmHg
Systemic Vascular Resistance (SVR) normal values - CORRECT ANSWER 800-1200
