questions with correct answers
LKC (leukocytes) - Answer-3.6-10.4 elevated in the presence of an infection. (also low
when septic or immunocompromised) (fibro neutropenia)
ERC(RBC) (erythrocytes) - Answer-3.65-5.00 (size) (amount)
Hgb (Haemoglobin) - Answer-Female-115-155, Male-130-170 (oxygen capacity)
Haematocrit - Answer-0.344-0.445 (Portion of your blood made up of RBC, monitors
conditions that effect RBC count) (indicator of fluid balance)
Platelet Count - Answer-130-400 (clotting capability)
NA (Sodium) - Answer-135-147 (fluid balance) (cardiac, CNS)
K (Potassium) - Answer-3.5-5 Critical for the electrical conduction of the heart.
Abnormal can cause lethal cardiac rhythms. (Lasix) (potassium depleting)
CL (Chloride) - Answer-98-110 (fluid balance) (acidosis/alkalosis)
Fasting Glucose - Answer-3.3-5.8 (see what baseline is)
Finger Sticks Glucose Accu Check - Answer-4-7 (give apple juice at 4) (recheck in 15
minutes)
HgbA1C - Answer-Assess glucose levels over a three month period. 4-6% is normal
values, less than 7% are ok, and greater than 8% represents elevated average blood
glucose levels
PT Prothrombin Time - Answer-0.8-1.2 10-13 sec When on anticoagulants the
therapeutic desired range will be higher than normal and the specific target will be
written in the doctors orders. (clotting) (warfarin affected mostly between 2-3)
INR International Ratio - Answer-0.9-1.2 When on anticoagulants the therapeutic
desired range will be higher than normal and the specific target will be written in the
doctors orders. Coumadin will affect INR results. (warfarin)
