Course 5: ED course Flashcards
What is in a CBC, what is the significance of each test
- WBC(White Blood Cells)High=infection
- Hgb(Hemoglobin)—Low=Anemia
- Hct(Hematocrit)—low=Anemia
- Plt(Platelets)—Low(Thrombocytopenia)=Prone to bleeding
Type of Lab studies
- Blood
- Urine
- Cultures
What is CBC with Diff, what is the significance of each test?
CBC tests+ more detailed look at WBC
- Bands—high(bandemia)=serious infection
- Segs(segmented Neutrophils—High(left shift)= acute infection
- Lymphs(lymphocytes)—High=Viral infection
- Monos(monocytes)—High=Bacterial Infection
- Eos(Eosinophils)—High=parasitic infection
Whats done in a CMP?
- BMP
- LFTs
What are the LFTs (liver function Tests)?
wALT wALKs pAST
Whats done in a BMP?
- Electrolytes
- Kidney Function
- BUN(Blood Urea Nitrogen)
- Creat(Creatinine)
- Blood Glucose
What tests are done in a CEP(Cardiac enzyme panel), what is important?
Looks for heart Damage
- Troponin
- CK(Creatine Kinase)
- Other Creatine tests
- Myo(myoglobin)
what are the 6 Cardiac Orders?
- CBC
- BMP
- CK, CK-MB
- Troponin
- EKG
- CXR
Respiratory labs and significance?
- BNP(B-type Natriuretic Peptide)
- High=CHF
- ABG(Arterial Blood Gas)
- VBG(Venous Blood Gas)
What Does a positive D-Dimer mean?
Possible PE, order a CTA Chest and VQ scan
What does a Negative D-Dimer mean?
No PE
What is important about D-Dimer?
- Signifies a PE
- SOB
- Pleuritic CP
- If Negative no blood clots, PE excluded
- Need CTA chest or VQ scan to diagnose PE
What does Troponin Test tell about pt?
- If it is high signifies a non-STEMi
- can take 4-12 hours for Troponin levels to rise
What test will show a Hemorrhagic CVA?
CSF RBC
3 Coag studies and significance
- PTT
- PT
- PT and INR
- INR
- Normal INR=1.0
- >3.0 Supratheraputic—>Too Much Coumadin
- <2.0 Subtheraputic —>Not enough Coumadin
What labs are used to test inflammation?
- CRP(C -Reactive Protein)
- ESR/Sed Rate( Erythrocyte Sedimentation Rate)
- if Either are high—>inflamation
What are the 4 ENT( ears, nose and throat labs)?
- Strep- Rapid Strep Test
- Monospot-Mononucleosis
- Influenza A+B
- RSV-Respiratory Synctial Test
- if positive likely bronchitis
CSF Analysis Tests
- DDx: Meningitis, hemorrhagic CVA(RBC)
- Tests
- CSF gluc
- CSF prot
- CSF RBC(hemorrhagic CVA)
- CSF WBC
- CSF Gram Stain
What Labs would you use to Diagnose Pancreatitis?
- Lip (Lipase)
- specific to pancreatitis
- Amy (Amylase)
- possible pancreatitis
What are the 3 Thyroid Labs?
- TSH(Thyroid stimulating hormone)
- Low- Hyperthyroidism
- High-Hypothyroidism
- T3
- T4
What are the OB/GYN Labs and their significance?
- HCG
- Positive=Preg
- Serum HCG Quant
- Higher/Unchanged= Further along in preg
- Lower=failed pregnancy
- Serum HCG Qual
- Positive=Preg
- Negative=Not Preg
- T+S/ABORh
- Rh Negative= Needs RhoGAM shot if pregnant
What are the Pelvic Exam Labs?
- Wet Prep(vaginal wet mount)
- GC (Gonococcus)
- CT (Chlamydia)
- Genital Cx (genital Culture)
What are the Three labs that are key for efficiency?
- D-Dimer-must order CTA Chest or VQ scan
- Troponin- Acute MI
- Creatinine(From BMP)-Kidney Function
What is the difference between the Urine Dip and Microscopic Urinalysis
- Urine dip can be done at bedside and is qualitative
- Microscopic Urinalysis is Quantitative
- Both can be used to determine if pt has a UTI or a Kidney Stone
