- 2PO280-100
- 3PCO235-45
- 4SaO295-100%
- 5HCO322-28
- 6BUN6-20 mg/dL
- 7Cholesterol (total)<200
- 8Glucose70-110
- 9Hematocrit (Hct)Represents RBC mass and is important measure of anemia and polycythemia. % RBC in volume of whole blood and is related to Hgb) Low could be anemia, destruction of RBCs (sickle cell, englarged spleen), decreased produx of RBCs (bone marrow supression, cancer, drugs)
M: 42-52%
F: 37-47% - 10HemoglobinMain component of erythrocytes and serves as vehicle for transporting oxygen and carbon dioxide. Carries O2 to body's tissues. Low could be anemia, pg, blood loss, cancer, kidney disease, enlarged spleen
M: 14-18 g/dL
F: 12-16 g/dL - 11HgA1c<6%
- 12Platelets150-400 mm3
- 13K+3.5-5
- 14Sodium135-145
- 15WBC5-10 mm3 but can be 5-15 during 3rd trimester of pregnancy
- 16Creatinine0.6-1.3 mg/dL
- 17PTProthrombin Time
10-12
1.5-2.5 times on coumadin - 18aPTTactivated partial thromboplastin time (activator is added to speed up clotting time)
how long to clot
25-30 sec
1.5-2.5x higher on Herparin
ONLY NEED TO MONITOR WITH unfractionated heparin - 19PTT30-45 sec (decreased in pg)
1.5-2.0x on Heparin
>100 is CRITICAL - 20INR0.9-1.2 seconds
Therapeutic on WARFARIN 2-3x normal
High dose warfarin 3-4.5x - 21Osmolalityconcentration of dissolved particles of chemicals and minerals (electrolytes) in serum. Higher osmolality = more particles, lower = diluted.
275-295 mmol/kg - 22MAP (Mean Arterial PressurE)Pressure in your arteries during one cardiac cycle shows how well the vital organs are being perfused
70-105 mmHg, less than 60 means vital organs underperfused
=(systolic+(diastolic * 2))/3 - 23Serum Carboxyhemoglobin<5% for nonsmokes, <10% for smokers
venous 22-30 mEq/L - 24Urine Specific GravityHow well kidneys are diluting urine. Higher=more dehydrated OR urine is becoming less dilute (more concentrated)
1.003-1.030 - 25Calcium8.6-10.2
- 26MagnesiumNormal: 1.3-2.1 mEq/L
Therapeutic: 4-7 mEq/L
Toxicity >7 - 27GFR125 mL/minute in young adult
decreases 10% each decade
Age 65 65 mL/min - 28T3, T4, TSHT3: 70-205 ng/dL
T4: 4-12 mcg/dL
TSH: 0.4-6 - 29BMINormal 18.5-24.9
- 30Mantoux testTB screening
client returns 48-72 hrs to assess for induration (>15 mm is positive)
if positive, chest x-ray - 31Creatine kinaseseverely elevated is considered over 15k U/L
- 32BNP-assess for HF
<100 normal
<125 pg/mL 0-74 yrs
<450 pg/mL 75-99 yrs - 33CVP (central venous pressure)2-8 mm Hg
Elevate: crackles, pedal edema, JVD
indicates fluid volume status - 34waste circumferenceincrease risk for metabolic disease if >40 in men and >35 in women
- 35systemic vascular resistance800-1200
- 36ANC2200-7700
