Pre-op Flashcards
Neutrophils
2nd line of defense
Fight infection
WBC
Total white blood count.
Fight infection.
-4,000-10,000 (4-10 on lab print out)
Neutrophils, lymphocytes, monocytes, basophils, eosinophils
Lymphocytes
1st line of defense.
Fight infection.
^neutrophils + low lymp = late stage if infection.
Eosinophils
Relate to allergies
RBC
Red blood cell
Contain hemoglobin for transport and exchange of oxygen
Male: 4.7-6.1
Female: 4.2-5.4
Hemoglobin
Male: 14-18
Female: 12-16
Hematocrit
Percentage of total blood volume made up by RBCs
Male: 42-52%
Female: 37-47%
Platelets
Essential to blood clotting
150,000-400,000
Sodium
Major determinant of extracellular osmolality
Normal: 136-145
Balance between dietary intake and renal excretion
Many other factors also regulate Na in body.
Helps determine how much fluid our body holds onto and how much is excreted
Potassium
Major cation within cells
Normal: 3.5-5
Excreted by the kidneys
Minor changes have significant consequences…high risk for muscle spasms or heart arrhythmias
K and Na balance each other and control fluid balance in the kidneys
Carbon dioxide
Normal: 23-30 mEq
Assists in evaluating pH status of pt and other electrolytes
Chloride
Normal: 98-106 mEq
Gives indication of acid- base balance
Maintain electrical neutrality with Na
Calcium
Normal: 7.6-10.4 mg/dl
Evaluates parathyroid function, calcium metabolism, monitor renal pts, other uses
BUN
Blood, urea, nitrogen
Normal: 10-20
Monitors kidney function
Creatine
Normal: .5-1.1
Monitors kidney function
Urinalysis
UTI, renal function, diabetes
Type & cross match
If any risk for blood loss
For matching blood types if extra blood is needed during a surgery with high risk of blood loss
ABGs
Arterial blood gases
Arterial blood caries oxygen going away from the heart
PTT
Prothrombin time
Clotting factor
Albumin/protein
Important for osmotic pressure within the vascular space
Measures nutrition
ALT
Alanine aminotransferase
Normal: 4-36
Monitors liver function
^ alt when in early stages of cirrhosis and liver damage etc
Benzodiazepines
Reduces anxiety
Induces sedation
Induces amnesia
Narcotics
Relieves discomfort during preop procedures
H2- receptors blockers or proton pump inhibitors
Increases gastric pH
Decreases gastric volume
