Practice Questions and Verified Answers
| Graded A+
• Normal Hemoglobin A1C Assay Result . Answer: 4.0 and below
• Pre-diabetic Hemoglobin A1C Assay Result . Answer: 7.0 and above
• Median Cubital Vein . Answer: most preferred and commonly used for
venipuncture.
-easiest to obtain blood from and less painful
-less prone to injury
• Select Lancet Size . Answer: Phlemotomist should ____ prior to
performing capillary puncture
• Chain of Infection . Answer: 1) Agent 2) Reservoir 3) Portal of Exit 4)
Mode of Transmission 5) Portal of Entry 6) susceptible host
• Infectious Agents . Answer: Viruses, Bacteria, Fungi, parasites
• Portal of Exit . Answer: Agent leaves its reservoir
,• standard precautions (or transmission-based precautions) . Answer:
designed by the CDC to decrease the risk of transmission of
microorganisms from both recognized and unrecognized sources of
infection in hospitals
-hand hygiene, gloves, masks, gowns, linen, needle-sheathing devices,
patient placement
-includes universal precautions that are designed to prevent transmission
of all infectious agents
-protection from contact with blood, all body fluids, mucous
membranes, and non intact skin
• 8-10 ML . Answer: When obtaining a blood culture from an adult, you
should collect _____
• Portal of entry . Answer: Allows infectious agent access to susceptible
host (broken skin, mucous membranes, and body systems exposed to
external environment such as gastrointestinal, respiratory, and
reproductive)
• Limit Transmission of infectious agent . Answer: Transmission-
based/standard precautions (gloves, mask), and aseptic technique (hand
washing)
• Susceptible Host . Answer: 'At risk', not resistant or immune
,• Infection control at susceptible host level . Answer: Identification of
the patients at risk, treat their underlying condition for susceptibility, or
isolate them from the reservoir
• Fasting Specimen . Answer: Usually glucose, cholesterol, triglycerides,
lipid panel test, vitamins (anything that has to do with food)
-usually between 8-10 hours
• Successful blood Smear . Answer: Will have 'feathered edge'
• Fecal Specimens . Answer: -patient should be instructed to avoid
urinating in the container because urine can kill the microorganisms
-Occult Blood (or 'hidden blood'), analyze for dietary products and
digestive secretions, decreased amount of bile
• Guaiac Test . Answer: test for occult or 'hidden' blood in stool
• Steatorrhea . Answer: Excessive amount of fat in stool- can indicate
faulty absorption of fat from small intestine
• Decreased amount of bile in stool . Answer: Indicates obstruction in
bile flow from liver and gallbladder to intestine as well as gallbladder
removal
, • Labeling blood samples . Answer: Must have patient name, ID(ULI
Number), DOB, date and time of collection, site location, collectors
initials
-date of birth is critical along with patient name
• Urine Specimen . Answer: label should be affixed on the container
NOT the lid
-if two patients specimens are near each other and without lids, it is
highly likely that mismatching of the tests' results to the patients will
occur
• capillary specimen site for children . Answer: Lateral or medial portion
of infant's heel (if child is not walking for 1 year)
• Age and Development . Answer: Factors that determine whether a
child will have capillary collection by heel or finger stick
• Detecting presence of ova and parasites in stool sample . Answer: Send
specimen as soon as possible, if it will be seen in >24 hours, **ice
sample (chill sample, put sample in refrigerator)
• Testing feces for occult blood . Answer: Use chemical reagent
substance to detect presence of enzyme peroxidase in hemoglobin
molecule
• Guaiac Test Results . Answer: Blue color- postive result
