A 25-gauge, zero.Five-inch needle is BEST used for a(n) ____ injection.
A. Intradermal
b. Intramuscular
c. Subcutaneous
d. Intravenous - ANS-c. Subcutaneous
Subcutaneous is the fine desire for a 25-gauge needle, as it has a small diameter and short
length as a way to now not penetrate deeply into the dermis. Thegauge and period of
needles for ntradermal, intramuscular, and intravenous injections are all exclusive.
A four-year old patient enters the radiology suite for chest radiography and appears
demanding. The child has never had the exam before. She isn't always speakme or
answering questions. The technologist should satisfactory try to talk with the kid via:
a. Taking as a good deal time as they want to explain the examination
b. In short exploring the radiology branch with the kid
c. Supplying the child candy for participating I the examination
d. Sitting eye level with the child and walking them thru the exam - ANS-d. Sitting eye
degree with the child and strolling them thru the exam
A affected person between 3 and five years old may not be able to purpose with the
technologist approximately the purpose of the exam. Walking thru the steps with the child
may be the exceptional approach to alleviate their strain. A tour of the department might be
hazardous, and taking an infinite amount of time to provide an explanation for a technique
may not be possible. The baby may not be capable of devour candy, so providing it is able to
now not be an awesome idea.
A backup timer for the automated exposure manage (AEC) serves to:

b. Limit the thermal loading of the anode
c. Growth inherent filtration
d. Modulate tube modern to reduce affected person exposure - ANS-a. Terminate the
publicity inside the occasion of equipment or operator mistakes
A assessment medium that shall we x-ray photons easily bypass thru it's miles taken into
consideration:
a. Radiolucent
b. Radiopaque
c. Opaque
d. Transparent - ANS-a. Radiolucent
A affected person is injected with a huge extent of fluid intravenously; that is known as a(n):
a. Intravenous push
,b. Bolus
c. Drip infusion
d. Drop waft - ANS-b. Bolus
A bolus is a huge quantity of injected fluid. An intravenous push is the action of rapid
injection of fluid. Drip infusion is the infusion of liquid into the vein, however can encompass
a big or small amount of liquid. Drop float isn't always a clinical time period utilized in
venipuncture tactics.
A terminally ill patient has asked the medical doctor about feasible volunteer opportunities in
the health center. She says that if she can volunteer inside the hospital, she might be
capable of make bigger her lifestyles a bit longer from doing proper deeds. This represents
the ____ stage of grief for the affected person.
A. Bargaining
b. Anger
c. Denial
d. Melancholy - ANS-a. Bargaining
The bargaining degree makes a speciality of the hope the patient has to increase her life.
Anger can occur once the affected person realizes her lifestyles is being interrupted with the
aid of the infection. Denial can include rejecting information and preferring to be left alone.
Depression affects the patient's mood or conduct concerning the illness, and may purpose
melancholy and mourning.
A wedge filter is a form of ______ clear out.
A. Inherent
b. Compensating
c. Brought
d. Trough - ANS-b. Compensating
A wedge filter out is a sort of compensating filter out. It is used to offer the receptor with
uniform publicity whilst imaging frame systems with various thicknesses (i.E., a foot). The
thick edge of the clear out is located over the skinny structural part and the skinny part is
located over the thick structural part.
According to NCRP Report No. 116, annual occupational publicity to the lens of the attention
have to not exceed:
a. 25 mSv
b. 50 mSv
c. A hundred mSv
d. 150 mSv - ANS-d. A hundred and fifty mSv
NCRP Report No. 116 states the yearly occupational exposure limit for the lens of the eye is
a hundred and fifty mSv, or 15 rem.
According to the American College of Radiology, which of the following are symptoms for
acquiring a skeletal survey?
1. Suspected non unintentional trauma
, 2. Skeletal dysplasias, syndromes, and metabolic problems
3. Neoplasms - ANS-1, 2, and three
All of the subsequent affect the spatial decision of an photo EXCEPT FOR:
a. KVp
b. Component length
c. Tube attitude
d. SID - ANS-a. KVP
Kilovolts top has an effect on receptor publicity and comparison handiest. Tube perspective
affects spatial decision because of unequal magnification of the element. Part size affects
spatial resolution due to magnification (larger elements growth the OID, which ends up in
decreased spatial resolution). SID affects spatial resolution due to beam divergence.
All of the following are within acceptable kVp accuracy variance for an exposure the usage
of eighty kVp EXECPT FOR ____ kVp.
A. 86
b. 84
c. 82
d. Seventy six - ANS-a. 86
The kVp variance is within +5%. At eighty kVp, the variance is 4 kVp (eighty x 0.05 = 4).
Therefore, 76-84 kVp is inside proper limits.
All of the following EXCEPT ___ will bring about an increase in AEC reaction time.
A. Decreasing the kVp
b. Increasing the focal spot length
c. Growing the part thickness
d. Increasing the SID - ANS-b. Growing the focal spot length
Increasing the focal spot length does not exchange the AEC reaction time It influences the
spatial resolution. Decreasing the kVp will increase the publicity time because extra photons
are absorbed, resulting in fewer accomplishing the mobile(s). The same is genuine for
increasing part thickness. Increasing the SID effects in an extended exposure time due to
beam divergence and the lower in the variety of photons achieving the cell(s).
An acceptable PA chest examination is taken the use of three hundred mA, zero.008
seconds, and one hundred ten kVp. If this examination is repeated the usage of an AEC that
has a minimum reaction time of 10 ms, which of the subsequent publicity elements could be
appropriate?
A. 400 mA, zero.006 seconds, one hundred ten kVp
b. Two hundred mA, zero.012 seconds, one hundred ten kVp
c. 600 mA, zero.004 seconds, one hundred ten kVp
d. All the above would be appropriate - ANS-b. Two hundred mA, 0.006 seconds, 110 kVp
The minimum reaction time (MRT) is the amount of time it takes for the AEC to discover and
respond to an exposure. In this situation, the MRT is 10 ms (zero.01 seconds). This
approach that the AEC will no longer terminate an exposure in less than zero.01 seconds.
A 25-gauge, zero.Five-inch needle is BEST used for a(n) ____ injection.
