NCLEX Lab Values Articles

NCLEX lab values: common reference ranges, units and trends, electrolytes, blood counts, acid-base and coagulation.

Lab-value questions on the NCLEX test interpretation more than recall. The NCLEX lab values cheat sheet lists common adult study examples, such as sodium 135–145 mEq/L, potassium 3.5–5.0 mEq/L and arterial pH 7.35–7.45, and stresses that the range and unit given in a question govern that item. It teaches a five-step way to read a result: confirm the test and the unit, use the range the question provides, look at the direction and trend, connect the result with the client's cues, and identify the decision the item is testing. It then covers electrolytes, the complete blood count, acid-base values, and coagulation and medication-related monitoring, lists common study mistakes and shows how to build your own lab sheet. Ranges and units can differ between sources, so treat these numbers as orientation points for study, not as instructions for patient care.
