Diagnostic Procedure Flashcards
Means accessing the bodies tissue organs or cavity through some type of instrumentation procedure
Invasive procedures
The body is not entered with any type of instrument; the skin and other body tissues, organs, and cavities remain intact
Noninvasive Procedures
Puncturing of a vein with a needle to aspirate blood
Venipuncture
An individual who performs venipuncture
Phlebotomist
Reveals the ability of the lungs to exchange gases by measuring the partial pressure of O2 (PO2) and carbon dioxide PCO2 and evaluates the pH of the arterial blood
Arterial Blood Gas (ABG)
Blood gases are ordered to evaluate:
- Oxygenation
- Ventilation and the effectiveness of respiratory therapy
3.Acid base level of the blood
A skin puncture performed when small quantifies of capillary blood are needed for analysis (blood glucose analysis)
Capillary Puncture
It refers to a venous catheter inserted into the superior vena cava through the subclavian, internal or external jugular vein
Central Lines
Two major components of routine analysis
Microscopic analysis
Macroscopic analysis
Includes color, appearance, odor, specific gravity, pH, protein, glucose, ketones, blood, bilirubin, and urobilingen, nitrite, and leukocytes
Macroscopic analysis
Includes RBC, WBC, epithelial cells, cast and crystals, and other substance such as bacteria, yeast, mucus spermatozoa and parasites
MICROSCOPIC ANALYSIS
The best term to collect urine for UA is in the?
MORNING AFTER THE FIRST VOIDING
Have the greatest influence on the specific gravity of urine subclavian, internal or external jugular vein; than requires strict sterile technique
Urea and uric acid
Governed by the hydrogen ion concentration of the urine
pH
Urine sample should be evaluated within?
1 hour of collection
It is said to be a _____ when the blood is invisible on inspection; blood can be detected only through a microscopic or biochemical means
Occult Blood
Is done to diagnose gastrointestinal bleeding ulcers, and malignant tumors
OCCULT BLOOD
Perform to identify both the mature invading organism and their susceptibility to commonly used antibiotics
Culture and Sensitivity Test
Standard precautions are used to collect the specimen from the site at a time when the microorganisms are present in large numbers, before the initiation of antibiotic therapy
CULTURE AND SENSITIVITY TEST
Done to evaluate the cell maturity, metabolic activity and morphologic variation of the cervical tissue
Papanicolauo Test (PAP SMEAR)
A lose dose radiographic study of breast tissue to reveal congenital abnormalities and lesions
Mammography
Normal values for hematocrit
M: 37-49%
F: 36-46%
Normal values for triglycerides
<150 mg/dL
Normal values for platelet count
150,000-350,000/mm³
Normal values for Cholesterol
Adults: <200 mg/dL
Normal values for hemoglobin
M: 13.8-18 g/dL
F: 12-16 g/dL
Composed of a pigment (heme) which contains iron, and a protein (globin)
HEMOGLOBIN (Hgb)
Are fragments of cytoplasm that function in blood coagulation
Platelets
Packed cell volume is a fast way to determine the percentage of RBC’s in the plasma.
Hematocrit
Is reported as a percentage because it is the proportion of RBCs to the plasma
Hematocrit
