What things are necessary for infections to occur? -CORRECT ANSWER-1.) A source
(infectious agent or germ)
2.) Susceptible person (non-vaccinated or immunocompromised)
3.) Mode of transmission
What is mode of transmission? -CORRECT ANSWER-The way the germs are moved through a
susceptible person
True or false: Alcohol-based hand sanitizers are capable of removing C-DIF and/or C-spores
from a person's hands. -CORRECT ANSWER-False; CDIF is not removed with just alcohol
based hand sanitizer, you must wash the spores away.
True or false: you MUST wear gowns, gloves, and a face mask with contact precautions. -
CORRECT ANSWER-False; contact precautions are direct contact, you must wear JUST gown
and gloves.
True or false: Droplet precautions include particles that are greater than 5 microns. -
CORRECT ANSWER-True
True or false: Airborne precautions include particles greater than 5 microns. -CORRECT
ANSWER-False; airborne precaution particles are LESS than 5 microns.
In which situation must a patient's door remain closed and you must wear an N95 mask? -
CORRECT ANSWER-Airborne precautions
,What is the goal of the sterile technique? -CORRECT ANSWER-To provide your patient with
an environment that...
1.) Promotes healing
2.) Prevents infection
3.) Minimizes the length of recovery time
What part of the gown is not considered to be "sterile"? -CORRECT ANSWER-The back of the
gown
True or False: You should give 30 strokes for washing your fingernails, and 20 strokes for your
each surface of your fingers, hands, wrist, forearms, and elbows. -CORRECT ANSWER-True
What is a hematoma? -CORRECT ANSWER-A localized collection of blood outside of the
blood vessel
What is the MOST COMMON complication associated with venipuncture? -CORRECT
ANSWER-Hemorrhage or hematoma
What culture is always done first regardless if it you use a vacutainer or syringe? -CORRECT
ANSWER-Blood cultures are always done first because they have to be sterile
The median cubital vein is used because it is... -CORRECT ANSWER-1.) Easily palpable
2.) Well-anchored
3.) Least painful
4.) Least likely to bruise
5.) largest vein in antecubital space
What are the blood tests associated with the colored top tubes? (Red, Gold, Light blue,
Lavender, Grey, Green, Pink) -CORRECT ANSWER-Red Top = Chemistry (BMP, CMP)
, Gold top = Chemistry (serology, immunology)
Light blue = Coagulation studies (PT/PTT, D-Dimer, INR)
Lavender top = CBC, CD4, A1C
Grey top = Lactic acid, lithium levels
Green top = Troponin, CK, ammonium level
Pink top = Titan screen
Which veins are not well-anchored and painful to draw from? -CORRECT ANSWER-Cephalic
and Basilic vein
Which vein in the arm is dangerous to try to stick because it lies next to the brachial artery
and medial nerve? -CORRECT ANSWER-Basilic vein
What angle are you going in at for a venipuncture? -CORRECT ANSWER-15-30 degree angle
What is the biggest contraindication of an ABG? -CORRECT ANSWER-Absence of arterial
pulse (probably occluded)
What is an Allen's test? -CORRECT ANSWER-A "collateral circulation test" where you occlude
the radial and ulnar artery to watch the hand blanch, and the blood should return almost
immediately after pressure is stopped. Positive means blood came back immediately (within
15 seconds).
With an ABG in the RADIAL artery, what angle do you use to go into the artery? -CORRECT
ANSWER-40-60 degree angle
With an ABG in the FEMORAL artery, what angle do you use to go into the artery? -CORRECT
ANSWER-60-90 degree angle
What variable affects the ABG results? How does it affect them? -CORRECT ANSWER-
Temperature affects the results, If Temp decreases, PO2, PCO2 decreases as well.
