CBET EXAM PRACTICE TEST QUESTIONS WITH ACCURATE
SOLUTIONS(100% GUARANTEED PASS)
In which imaging modality is iodine used as a contrast element? -- Answer ✔✔ CT scan
Which NFPA document covers safety in a healthcare environment? -- Answer ✔✔
NFPA 99
A device that receives a signal in the form of one type of energy and converts it to a
signal in another form is a? -- Answer ✔✔ transducer
What is the true power of a 24 Vac parallel RL circuit when R = 45 Ω and XL = 1.1 KΩ
P = V2 / R
2
P =
= = 12.8 W
XL affects the overall impedance and apparent power, while true power relies only on
the resistance R.
-- Answer ✔✔ 12.8 W
The best solution for reducing excessive leakage current is? -- Answer ✔✔ use a third
or safety ground wire
A resistor that changes resistance with a change in temperature is known as a? --
Answer ✔✔ thermistor
What is the total resistance (Rt) of the following four resistors in parallel: 300 Ω, 600 Ω,
1200 Ω, 1500 Ω?
1/Rt = 1/R1 + 1/R2 + 1/R3 +1/R4
= 1/300 + 1/600 + 1/1200 + 1/1500
= 13/2000
, -1
Rt = (13/2000) = 153.846 Ω
-- Answer ✔✔ 153.846 Ω
The valve between the left atrium and the left ventricle is the? -- Answer ✔✔ mitral
valve
Describe the phase relationship between voltage and current in an inductive circuit. --
Answer ✔✔ voltage leads current by 90 degrees
The value of the inductor when the resonant frequency is 100 kHz and the capacitor
value is 25 pF is?
f = 1 / (2π√(LC))
L = 1 / (2πf)2 * C
f = 100000 Hz
C = 25 * 10^-12 = 2.5 * 10^ -11
L = 1/ (2π*100000)2 (2.5 * 10^-11)
L = 1/9.8696= (1/9.8696)-1
=0.101
= 0.101 * 1000 = 101 mH
-- Answer ✔✔ 101 mH
What is the color of a medical carbon dioxide gas tank? -- Answer ✔✔ grey
A good 1.2 watt light bulb is placed across a 12-volt battery. The resistance the bulb has
is:
P = 1.2
V =12
R=?
P = V2 / R
R = V2 /P = (122/1.2) = 120 Ω
-- Answer ✔✔ 120 Ω
