Acute Care Lab Values Cheat Sheet (DRAFT) by

Quick reference for acute care lab values for physical therapy

This is a draft cheat sheet. It is a work in progress and is not finished yet.

White Blood Cells

CVs: < 2,500 or > 30,000
Upward Trend: acutely ill, fever, and fatigue.
Downward Trend: high chance of infection, fatigue, and oncologic emergency if neutro­penic and fevered.

Platelets

CVs: < 50,000 or > 1 million
Upward Trend: headache, dizziness, tingling in hands and feet, and screen for VTE.
Downward Trend: high chance of bleeding, easily bruising, and especially mind fall risk.

HGB, Hemato­crit, and RBC

HGB CVs:
< 5 or > 20
Hematocrit CVs:
< 15% or > 60%
Red Blood Cells (normal)
Male: 4.7-6.1, Female: 4.2-5.4
Generally for all 3:
- Upward Trend: fatigue, headaches, weakness, dizziness, and VTE monitor.
- Downward Trend: also known as anemia, OH, dizziness, headaches, pallor, dyspnea, keep in mind CVA, cardiac, or renal conditions and signs for poor perfusion (disco­lor­ation, peripheral pulses, decreased temp, and angina).

Coagul­ation Tests

APTP
CV: >70 secs
Prothr­ombin Time
CV: 20 secs
INR
CV: > 5.5
These are your very high bleed risks and potent­ially sponta­neuous bleed risks. Very high caution for falling and even things like BP cuffs can bruise these patients.
 

Sodium

CVs: < 120 or > 160
Upward Trend: confused, thirsty, tachyc­ardic, hypote­nsive, seizure risk, and cardiac rhythm monito­ring.
Downward Trend: OH, edema, confused, weakness, lethargic, seizure, and coma.

Calcium

CVs: < 6 or > 13
Upward Trend: weakness, ventri­cular dysthymia, nausea, lethargy, and patients undergoing oncology treatment are at risk for hyperc­alcemia (alert team for oncologic emerge­ncy).
Downward Trend: confusion, cramping, seizure precau­tion, dysrth­ymia, fatigue, parest­hesia, and your chronic patients can present with osteopenia or osteop­orosis.

Potassium

CVs: < 2.5 or > 6.5
Upward Trend: muscle weakne­ss/­par­alysis, parest­hesia, dysrhy­thmia, bradyc­ardia, > 5 is an increased risk of dysrhy­thmia, and assess for ascending muscle decline that could become paralysis.
Downward Trend: extremity weakness, parest­hesia, dysrhy­thmia, hypote­nsion, < 2.5 is an increased risk of dysrhy­thmia, and assess for ascending muscle decline that could become paralysis.

Other Electr­olytes

Chloride
CVs: < 80 or > 115
Phosphate
CVs: < 1.0
Magnesium
CVs: < 0.5 or > 3
 

Kidney Functon

Blood Urea Nitrogen
CVs: > 100
Serum Creatinine
CVs: > 4
For Both:
- Upward Trend: edema, fatigue, confusion (SC), hypert­ension (BUN), confusion, polydipsia (BUN), nausea (BUN), abdominal or back pain (SC), and dyspnea (SC).
- Downward Trend (mainly BUN): fatigue, nausea, headache, and confusion.

Arterial Blood Gases

pH
CVs: < 7.25 or > 7.55
PaCO2
CVs: < 20 or > 60
HCO3
CVs: < 15 or > 40
PaO2
CVs: < 40

Hepatic Panel

Serum Albumin
CV: < 1.5
Serum Prealbumin
CV: < 10.7
Serum Bilirubin
CV: > 12
Serum Albumin & Prealb­umin:
- Upward Trend: fatigue, dizziness, and OH.
- Downward Trend: hypote­nsion and peripheral edema.
Serum Bilirubin
- Upward Trend: will produce yellow tint to body tissues, abdominal pain and bloating, and associated with neurol­ogical manife­sta­tions such as confusion, hyperr­efl­exia, and muscle tremors.

Glucose

CVs: < 50 or > 400
Trending Upward: polyuria and dipsia, blurred vision, fatigu­e/w­eak­ness, and dizziness.
Trending Downward: pale, weakness, tachyc­ardia, LoC, seizure, and lethargy. 15-30g of fast acting carbs recomm­ended if blood glucose is < 100.
