Course 5: ED Course Flashcards
What lab order contains the “H&H”?
CBC-Complete Blood Count
What is the difference between BMP and CMP?
BMP-basic metabolic panel; contains electrolytes, kidney function and glucose levels
CMP-comprehensive metabolic panel; BMP in addition to e LFTs
What part of the CBC does a “differential” further characterize, RBC or WBC?
WBC
What does creatinine measure?
Renal function
What is high potassium level called?
Hyperalkalemia
What organ do LFTs investigate?
Liver
How would you document Aspartate Transaminase?
AST
Which cardiac enzyme is more specific to heart damage, troponin or CK-MB?
Troponin
What does a negative D-Dimer mean?
No evidence of a PE
What does a positive D-Dimer mean?
Possible PE, must order a CTA chest or VQ scan
What does an elevated BNP diagnose?
Congestive Heart Failure
Dies the blood sample for an ABG come from a vein or an artery?
Artery
Name the parts of the cardiac order set (5)
- CBC
- BMP
- Troponin
- EKG
- CXR
What procedure must first be performed before CSF Cana be obtained?
Lumbar puncture
What do “Coag” lab tests examine?
Blood coagulation/ Coumadin levels
Name the 3 “Coag” level tests
- PT
- PTT
- INR
What does lipase diagnose?
Pancreatitis
What do both CRP and ESR test for?
Inflammation
CRP=C-Reactive Protein
ESR=Erythrocyte Sedimentation Rate

No
What is the difference between a Urine Dip and a Urine Micro?
Urine Dip: done bedside and detects leuks, nitrites, glucose, blood
Urine Nitro: in last and detects WBC, RBC and bacteria
Name the 3 labs important to track for efficiency
1) Troponin
2) Creatinine
3) D-Dimer
What type of body structure are XR’s best suited to examine?
Bones
What is the difference between CTA and CT?
CTA= CT angiogram looks at the arteries using IV contrast
CT=no IV contrast but may or may not use PO contrast
