Preload - ANS ✔✔The filling pressure of the ventricle at the end of ventricular diastole in known
as?
Right Ventricular End-Diastolic Pressure (RVEDP) - ANS ✔✔Which measurement is typically used
to indicate right ventricular preload?
32% (stroke volume / end-diastolic volume = = 0.32) - ANS ✔✔Calculate the ejection
fraction of a female patient with a stroke volume of 40 mL and an end-diastolic volume of 125
mL.
1. The catheter tip must face upstream
4. The transducer must be level with the catheter tip - ANS ✔✔Which of the following is true
concerning the insertion of a radial arterial line?
1. The catheter tip must face upstream
2. The catheter tip must face downstream
3. The transducer must be higher than the catheter tip
4. The transducer must be level with the catheter tip
Remove the catheter (there is a clot or kink in the catheter) - ANS ✔✔While attempting to draw
blood from an indwelling arterial catheter, the RT notices a dampened waveform and has
difficulty withdrawing blood for sampling. What should the RT's immediate action be?
, Check the other side - ANS ✔✔The RT preparing to insert an arterial line in the right radial
artery performs an Allen's test. The result of the Allen's test is 20 seconds. What should the RT
do?
Catheter knotting - ANS ✔✔Excessive pulmonary artery catheter movement can cause what to
occur?

is?
11.86% ( Arterial Oxygen Content = Hemoglobin (Hb) x 1.34 x SaO2 + (PaO2 x 0.003) = 9 x 1.34
x .96 + (97 x 0.003) = 11.5776 + 0.291 = 11.8686 %) - ANS ✔✔Calculate the arterial oxygen
content for a patient with the following arterial blood gas measurements: Hemoglobin (Hgb) 9,
arterial oxygen saturation (SaO2) 96%, arterial partial pressure of oxygen (PaO2) 97 mm Hg.
3.7 (Fick Equation = Cardiac Output = Oxygen Consumption / (Arterial Oxygen Content - Mixed
Venous Oxygen Content) x 10 = 280 / (19.5 - 12) x 10 = = 3.7) - ANS ✔✔Calculate
cardiac output using the Fick Principle for the following values: Oxygen consumption 280
mL/min, Arterial oxygen content 19.5 vol %, Mixed venous oxygen content 12 vol %

✔✔Calculate the stroke index using the following data: cardiac output 3.7 L/min, Heart rate 90,
Body Surface Area 1.7
48.96% (Left Ventricular Stroke Work = (Mean Arterial Pressure x Stroke Volume) x 0.00136 =
[MAP = (Diastolic Pressure x 2) + Systolic Pressure / 3] = (60 x 2) + = MAP 72; 72 x 50 x
0.0136 = 48.96) - ANS ✔✔The hemodynamic values for a patient in the cardiovascular care unit
