Lab Values Flashcards
What is the range of serum creatinine?
What do you do outside of these ranges (i.e. what is the level)?
0.6-1.2
Level A - Abnormal
- Do not have to do anything
- Report when you can
What is the range of INR?
What do you if greater than 4?
2-3
Level C - Critical
- Hold medication
- Assess (focused)
- Prepare to give
- Call DR
What is the range of potassium?
What do you do if greater than 5.3?
What do you do if less than 3.5?
What do you do if more than 6?
3.5-5.3
Level C - Critical
- Hold medication
- Assess (focused) heart/ecg
- Prepare to give d5w w insulin iv
- Call DR
Level C - Critical
- Assess heart/ecg
- Prepare to provide K supplement
Level D - Deadly
- Team work to (cannot leave PT):
- Assess (focused) heart/ecg
- Prepare to give d5w w insulin iv
- Anticipate calling CCOT team
What is the normal pH range?
What to do if pH is in the 6 range?
7.35-7.45
Level D - Deadly
- “As the pH goes down, so does my PT”
- Assess vitals
- Call DR
What the range of BUN?
What is the priority level of BUN?
What if it is elevated?
8-25
- Think 8 buns in a pack
Level A - Abnormal
- Just assess for dehydration
If they give you an elevated blood level, and you have no idea what it is, what should you guess?
Think dehydration - they go up because of concentration
What is the range of hemoglobin (Hgb)?
What if the range is lower (8-11)?
What if the range is below 8?
12-18
Level B - Be Concerned
- Assess for anemia, bleeding, or malnutrition
Level C - Critical
- Assess bleeding
- Prepare blood
- Notify DR

What priority level is it?
22-26
Level A - Abnormal
What is the range of carbon dioxide?
What to do if high in the 50’s?
What to do if greater than 60?
35-45
Level C - Critical
- Assess respiratory
- Assist client with breathing
- Call DR if no improvement
Level D - Deathly
- Assess respiratory
- Prepare to intubate
- Call RT and then DR
What is the range of PO2?
What if it is less than 70?
What if it is less than 60?
78-100
Level C - Critical
- Assess respirations
- Prepare to give oxygen
Level D - Deathly
- Give oxygen
- Assess respirations
- Prepare for intubation
- Notify RT and DR
What is the range of O2?
What if it is less than 93?
What if the question asks for:
1) First
2) Best
93-100
Level C - Critical
- Assess RR
- Raise HOB
- Give oxygen
Answer accordingly:
- First = Raise HOB
- Best = Give oxygen
What is the range of hematocrit (Hct)?
What if the range is past the high end?
36-54
- Hint: This is 3x the value of Hgb!
Level C - Critical
- Assess for dehydration
What are the 5 deadly d’s?
- Potassium greater than 6
- pH less than 6
- O2 < 60
- CO2 in the 60s
- Plt less than 40,000
What is the range of BNP?
What if the range is higher than the high end?
Less than 100
Level B - Be Concerned
- Assess for S/S of heart failure (CHF/AHF)
When someone is hypoxic, which rate increases first? RR or HR?
Heart rate
- Speeds up to compensate
When the heart can no longer compensate, RR goes up
What is the range of Na?
What level is abnormal ranges of Na? Unless…
135-145
Level B - Be concerned
- High = dehydration
- Low = overload
Unless… LOC decreases then Level C = Critical
What is the Plt range?
What if it is less than 90,000?
What if it less than 40,000?
150,000 to 400,000
Level C - Critical
- Bleeding precautions
Level D - Deathly
- Notify DR
- Prepare for Plt transfusion
What is the RBC range?
What level is abnormal ranges?
4-6 million
Level B - Be concerned
What is the WBC range?
What level is abnormal ranges?
5,000-11,000
Level B - Be Concerned
- If elevated, usually leukocytosis
- If low, leukopenia, neutropenia, immunosuppression (private room, strict hand washing, shower BID with antimicrobial wash, NO crowds/flowers, fresh water only)
When is O2 false?
In anemic PT’s and after using dye in procedures
What is the absolute neutrophil (ANC) count range?
What level?
> 500
Level C - Critical
- Precautions (private room, strict hand washing, shower BID with antimicrobial wash, NO crowds/flowers, fresh water only)
CD forecourt
- What do you have if above or below?
What level?
200
- Less than 200 = Aids if lower
- More than 200 = HIV
Level C - Critical
- Precautions (private room, strict hand washing, shower BID with antimicrobial wash, NO crowds/flowers, fresh water only)
