Exam 3 Study Guide
Labs:
• Complete blood count (CBC)- Page 720-721
• Basic metabolic panel (BMP/Chem 7)-
- BUN: measure urea
- Creatine: renal function
- Potassium: regulates fluid balance
- Normal: 3.5 - 5.3 me/L
- Sodium: regulates fluid balance
- Normal: 135 – 145 me/L
- Calcium: bone strength
- Normal: 4.5 – 5.5 me/L
- Chloride: regulates fluid balance
- Normal: 95 – 105 me/L
- Glucose: 70-110 mg/dL
Specimens Procedures:
• Blood glucose-
1. Make sure finger is warm
2. Hold in dependent position
3. Clean
4. Prick side of finger
5. Wipe away first droplet (if used alcohol to clean)
6. Collect
• Stool specimen (Occult or Qualla)- indicated ulcers, inflammation, or tumors
, - Avoid collection during period or 3 days after
- Flush toilet twice before or use a clean bedpan
- Avoid contaminating sample with urine or toilet paper
- Use tongue blade to transfer specimen to test folder
- Collect from two different areas
• Stool specimen (steatorrhea)- fat in the stool indicates a small intestine issue
- Must send full sample
- Send to lab immediately

Preparing for Mathematics ExamsMathematics requires
• Clean catch urine-
- Wash and dry perineal from front to back on women, retract foreskin
and clean the distal portion
- Tell patient to start voiding
- Catch it mid-stream
- Cap container and label
- Send to lab immediately
• 24-hour urine-
- Discard first, then save every after
- Put on ice or in a refrigerator
- If you miss one, you MUST start over
- End time void goes in main container
• Foley Cath-
- Tilt back and forth to empty bladder before clamping
- Clamp
- Wait 10-15 or 30 minutes
- Insert syringe at 30-45° angle
- Unclamp catheter
- Withdraw required amount
- Transfer to specimen container
, - Cap and label
- Send to lab immediately
Procedures:
• CT scan- soft tissue
- IV pyelography is contrast medium injected to visualize urinary/kidney
structures
• MRI- soft tissue (brain, spine, limbs, joints, heart, blood vessels, abdomen, pelvis)
- Provides better contrast between normal and abnormal tissue than a CT scan
does
- MUST remove all metal objects
- Patients with metal implants cannot have MRIs
- Tattoos can become very hot during procedure
- Ask patient if they are claustrophobic

• PET- Cancer and tumors
- Injection or inhalation of radioisotope
- Distribution of isotope is different in normal tissue than in diseased tissue
• Lumbar puncture- Diagnose serious infections
- Cerebrospinal fluid is withdrawn then inserted into the
subarachnoid space of the spinal canal between the 3rd & 4th or 4th
and 5th vertebrae
- Patient is positioned laterally with head bent toward chest, knees
flexed onto the abdomen, and back at the edge of the bed
- Tell patient to lay flat after procedure to reduce risk of ‘spinal headache’
- At risk for meningitis and subsequent sepsis if sterile is broken
• Abdominal paracentesis- Relieve pressure on abdominal organs causes by
excessive fluid or to obtain fluid specimen
- Needle is inserted into abdominal cavity or pleural space to drain off fluid
- 1500 mL is the max amount of fluid taken out and it is taken out
