4
Answer 80-120

Introduction

• Phlebotomy-collection of blood from a vein via
  needle stick.
• Arteries-are accessed routinely only by medical
  doctors and respiratory therapists.

6
Most Commonly Used Veins

• Antecubital-bend of elbow.
• Median cubital and median cephalic-forearm just
  below bend of elbow, most often used.

7

• Scalp-infants and children under one year.
• Heel-infants and children under one year.

8
This Belongs to Who?

• Label all tubes with patient name, doctor name
  and patient birth date.

Over-The-Counter Glucose Test
10
Glucometer

• A machine that measures blood
• sugar level.

11

• 1. Turn on glucometer and check calibration by
  looking for 8s as it boots up.

• 2. Insert glucostrip into glucometer.

13

• 3. Wipe off the first drop of blood with sterile
  gauze.

14

• 4. Place 1 drop of blood on the glucostrip and
  press start.

15

• 5. Read glucose level when alarm sounds.

16

• REMEMBER
• Normal glucose level is 80-120.
• Report levels below 40 and above
• 200 immediately.

17
Gross Analysis
????
18

• Gross analysis is determining what you can,
  about specimens, using your basic special senses
  without any special equipment.

19
Use sense(s) appropriate for specimen.

• Inspection (vision)-check amount, color,
  concentration.
• Olfaction (smell)-check odors.
• Auscultation (hearing)-check sounds.

20

• Palpation (touch)-check how it feels.
• Never taste specimens.
