Saunders book says 35-65mg/dL, CD 15-45, Kaplan 80-110. A bit too much difference for me.
Quote from mariaspapias
i've run into the same problem studying for boards. so how does 15-45 mcg/dl equal 80-110 g/dl?? is there something i'm missing?
nclex prints details of the what is on the test on their website so you know what to expect. this is the current one for the nclex-rn: https://www.ncsbn.org/2007_nclex_rn_..._candidate.pdf
. on page 38 of this document regarding laboratory values it lists the following:
- know laboratory values for abgs (ph, po2, pco2, sao2, hco3) bun, cholesterol (total) glucose, hematocrit, hemoglobin, hemoglobin a1c (hba1c), platelets, potassium, rbc, sodium, urine specific gravity and wbc
- recognize deviations from normal for values of albumin (blood), alt (sgpt), ammonia, ast (sgot), bilirubin, bleeding time, calcium (total), cholesterol (hdl and ldl), creatinine, digoxin, esr, lithium, magnesium, ptt and aptt, inr, phosphorous/phosphate, protein (total), pt, urine (alb, ph, white blood cell count [wbc] and differential)
- obtain specimens other than blood for diagnostic testing (e.g., wound cultures, stool, urine
- obtain blood specimens peripherally or through central line
- notify primary health care provider about laboratory test results
- monitor client laboratory values (e.g., glucose testing results for the client with diabetes)
- provide client with information about the purpose and procedure of prescribed laboratory tests
you don't need to convert any lab values. for ammonia, you merely need to know what the normal levels are and be able to recognize what is abnormal
no matter what system of measurement is used. you need to get a lab reference that will give you the normal levels in various measurements. if you do not have a lab reference book with this information, try looking for it on any of these websites:
the people who write the nclex are aware that the test is taken all over the country and that many different labs use different methods to test for these lab values. they are trying to keep the test fair, so they will not tie you down to something very, very specific. that is why they are going to ask for deviations from normal
when it comes to ammonia levels.
