N370-03: Renal
Labs & Diagnosis pt. 1
| Levels/Order | Interpretation/Indication |
|---|---|
| 60 or higher | Normal GFR range. |
| Below 60 | Indicates kidney disease. |
| Below 15 | Indicates kidney failure. |
| 0.5-1.5 | Normal creatinine level. |
| Creatinine | _____ is measured in the BLOOD; a byproduct of MUSCLE BREAKDOWN |
| Increased | We expect (decreased or increased) creatinine in the blood when kidneys are not adequately filtering out wastes. |
| Creatinine clearance | ______ measures the creatinine in the URINE within a 24 hour period; this is the creatinine that was cleared from the body. |
| Decreased | We expect (decreased or increased) creatinine clearance when less creatinine is effectively filtered out. |
| 11-20 | Normal creatinine clearance. |
| 1.010 (diluted)-1.030 (concentrated) | Normal urine specific gravity levels. |
| 7.35-7.45 | Normal pH level. |
| 22-26 | Normal bicarbonate (HCO3) level. |
| 35-45 | Normal paCO2 level. |
| 80-100 | Normal PaO2 level. |
| Blood Urea Nitrogen (BUN) | ______ is measured in the BLOOD; the byproduct of PROTEIN BREAKDOWN (highly affected by hemodilution or hemoconcentration - "HSB") |
| 8-25 | Normal BUN level. |
| True | T or F: BUN is elevated during hemoconcentration/FVD -> hepatic/renal impairment, dehydration, high protein diet, infection, steroid use, GI bleed |
| False; hemodilution/FVO | T or F: BUN is decreased during hemoconcentration/FVD -> malnutrition, fluid volume excess, severe hepatic damage (dec clot factors -> thinner blood) |
| Increased | Creatinine is (increased/decreased) ONLY w/ renal impairment. |
| Decreased | Creatinine is (increased/decreased) with reduced muscle mass/muscle breakdown. |
| 10:1 to 20:1 | Normal BUN to Cr ratio. |
| Increased | (Increased/Decreased) ratio means FVD or hypoperfusion. |
| Decreased | (Increased/Decreased) ratio means FVO or malnutrition. |
| Increase | (Increase/Decrease) in BOTH means renal impairment. |
| True | T or F: If pt has CHRONIC renal failure managed on dialysis, normal values for them are going to be far from the usual normal -> consult with med team for the PATIENT'S NORMALS. |
| OK | *Know urinalysis findings* |
| T | Potassium and Calcium affect the heart's __ wave. |
| Peaked (hyper - up high) | Hyperkalemia will cause (peaked/flat) T wave. *Inversed with hyperkalemia* |
| Prolonged (hypo - slow - takes so long to get there); chvostek's and trousseau's signs | Hypocalcemia will cause (prolonged/fast) QT interval. *Inversed with hypercalcemia*; expect to see positive _____ . |
