ORPEDIC NURSE CERTIFICATION: AN A+ QUESTIONS AND
ANSWERS PLAYBOOK
Anything that is a risk to organisms, such as ionizing radiation or harmful bacteria or viruses
Blood borne Pathogens
Pathogenic micro-organisms that are present in human blood and can cause disease in humans
Catheter
A hollow, flexible tube that can be inserted into a vessel or cavity of the body to withdraw fluids
Chain of Custody
The chronological documentation showing the seizure, custody, control, transfer, analysis, and
disposition of specimens, which can be used as evidence
Chemical Reagent Strip Testing
Method of urinalysis involving the use of plastic strips to which chemically specific reagent pads
are affixed.
Clean-catch midstream specimen
Method of urine collection, ordered to diagnose urinary tract infections or to evaluate the
effectiveness of drug therapy.
Dermal Puncture
Procedure in which a finger or heel is lanced to obtain a small quantity of blood for testing, also
called a capillary draw, finger stick, heel stick, or skin puncture.
Ethylenediaminetetraacetic acid (EDTA)
Used as anticoagulant to keep blood specimens from clotting
Enteric
Pertaining to the intestines
Galactosemia
Inherited disorder in which the body is unable to use, or metabolize, sugar galactose, causing
the patient to be unable to tolerate any form of milk, foods containing galactose.
Hematocrit
Proportion of the blood that consists of packaged red blood cells, expressed as a percentage by
volume; the hematocrit test measures the percentage of hematocrit in the blood.
, Occult blood
Blood that comes form a source that cannot be immediately determined, such as a peptic ulcer.
Phenylketonuria (PKU)
A metabolic genetic disorder characterized by a deficiency in the hepatic enzyme phenylalanine
hydroxylase; classic PKU causes permanent intellectual disability, seizures, delayed
development, behavioral problems, psychiatric disorders, a "mousy" body odor, lightening of
skin and hair, and eczema.
Point of care
At or near the site of patient care
Quality control
Method of repeated assay of known standard materials and monitoring reaction parameters to
ensure precision and accuaracy
Random specimen
Single urine specimen taken at any time
Reagents
Chemical substances known to react in specific ways; used to detect or synthesize other
substances in chemical reactions
Reference laboratory
Laboratory outside a patient care facility; able to perform many more types of testing than at
the hospital laboratory
Semen
Thick, whitish secretion of the male reproductive organs discharged from the urethra during
ejaculation.
Sputum
Material coughed from the lungs and expectorated through the mouth.
Stool
Waste form the digestive tract that is formed in the intestine and expelled through the rectum;
also called feces.
Suprapubic
