Flashcards in Pre-op Deck (27):
0

WBC

Total white blood count.
Fight infection.
-4,000-10,000 (4-10 on lab print out)
Neutrophils, lymphocytes, monocytes, basophils, eosinophils

1

Neutrophils

2nd line of defense
Fight infection

2

Lymphocytes

1st line of defense.
Fight infection.
^neutrophils + low lymp = late stage if infection.

3

Eosinophils

Relate to allergies

4

RBC

Red blood cell
Contain hemoglobin for transport and exchange of oxygen
Male: 4.7-6.1
Female: 4.2-5.4

5

Hemoglobin

Male: 14-18
Female: 12-16

6

Hematocrit

Percentage of total blood volume made up by RBCs
Male: 42-52%
Female: 37-47%

7

Platelets

Essential to blood clotting
150,000-400,000

8

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

9

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

10

Carbon dioxide

Normal: 23-30 mEq
Assists in evaluating pH status of pt and other electrolytes

11

Chloride

Normal: 98-106 mEq
Gives indication of acid- base balance
Maintain electrical neutrality with Na

12

Calcium

Normal: 7.6-10.4 mg/dl
Evaluates parathyroid function, calcium metabolism, monitor renal pts, other uses

13

BUN

Blood, urea, nitrogen
Normal: 10-20
Monitors kidney function

14

Creatine

Normal: .5-1.1
Monitors kidney function

15

Urinalysis

UTI, renal function, diabetes

16

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

17

ABGs

Arterial blood gases
Arterial blood caries oxygen going away from the heart

18

PTT

Prothrombin time
Clotting factor

19

Albumin/protein

Important for osmotic pressure within the vascular space
Measures nutrition

20

ALT

Alanine aminotransferase
Normal: 4-36
Monitors liver function
^ alt when in early stages of cirrhosis and liver damage etc

21

Benzodiazepines

Reduces anxiety
Induces sedation
Induces amnesia

22

Narcotics

Relieves discomfort during preop procedures

23

H2- receptors blockers or proton pump inhibitors

Increases gastric pH
Decreases gastric volume

24

Antacids

Increases gastric pH

25

Antiemetics

Increases gastric emptying
Decreases N/V

26

Anticholinergics

Decreases oral and respiratory secretions.
Prevents bradycardia
