What is CBC?
These are normal results for a common lab test: 13.2 and 16.6 gm/dL and 11.6-15 gm/dL
What are normal hemoglobin levels in men and women?
Platelet count < 150,000 mcL
What is thrombocytopenia?
Possible explanations for patient's potassium level of 7.5mEq/L
What is hemolyzed specimen or kidney failure?
Check patient history and lab trends!
Fatigue, nausea, confusion, seizures, coma are symptoms of this electrolyte imbalance
What is hyponatremia?
This lab is the best choice when screening for thyroid dysfunction
What is thyroid-stimulating hormone (TSH)
Therapeutic INR for a patient without a mechanical valve
What is 2-3?
White blood cell count < 3700 cells/mm3
What is leukopenia?
Interpretation of routine lab results for a patient with a normal creatinine and high BUN.
What is the patient is dehydrated?
This enzyme elevates approximately 4-6 hours after injury and peaks in 10-24 hours.
What is troponin?
This type of panel is ordered to detect changes in the ALT, AST, Total Protein, and Total Bilirubin
What is a hepatic (liver) panel?
Therapeutic INR for a patient with a mechanical valve
What is 2.5-3.5?
Heme by-product from aged red blood cells
What is bilirubin?
A patient's labs reveal increased D-dimer, increased fibrin degradation products, and decreased fibrinogen leading to a suspicion of this condition.
What is disseminated intravascular coagulation (DIC)?
A unit of PRBCs will raise the HCT by this percentage in the average adult.
3%
1 unit of PRBC will raise the Hgb 1g/dL
These labs are ordered for a patient admitted with DKA
What are hourly glucose, serum electrolytes, and ABG?
These types of cells will be increased on a differential in patients with allergies and asthma.
What are eosinophils?
These are immature neutrophils.
What are Bands?
Typically released early from the bone marrow in response to infection or inflammation ("bandemia")
Possible diagnosis for a patient with an amylase level of 247 U/L and a lipase of 114 U/L.
What is pancreatitis?
Normal amylase: 25-125 U/L
Normal lipase: 10-140 U/L
Acidosis, hypoxia, hyperthermia, and increased 2,3-Disphosphoglycerate will cause this to occur.
What is a shift to the right on the oxyhemoglobin curve?
Decreased O2 affinity
Do this if a patient's INR is 4.2
What is order:
4-factor Prothrombin Complex Concentrate or 3-factor PCC and Fresh frozen plasma. If 3 or 4-factor PCC not available, administer FFP alone.
2. Intravenous Vitamin K10mg.
3. Consider Tranexamic acid administration
The term for a differential that reveals a PMN count > 80 or bands >10-12%
What is a left shift?
Indicates bacterial infection, toxemia, hemorrhage, or myeloproliferative disorders
The name of the standard test for tuberculin skin testing.
What is the Mantoux test?
Interpret patient's recent labs: pH >7.3; serum glucose >600mg/dL; serum osmolarity >320 mOsml/L; ketones none to minimal
What is hyperosmolar hyperglycemic state (HHS)?
These 3 common electrolyte abnormalities may cause prolonged QT interval
What are hypocalcemia, hypomagnesemia, and hypokalemia?
