0.5 is the number to remember for Creatinine.Ĭ reatinine for women is 0.5 – 1.1 mg/dL (44-97 mcmol/L) and for men is 0.6-1.2 mg/dL (53-106 mcmol/L).īUN is 10-20 mg/dL, which is about 20 times greater than creatinine for US values (0.5 x 20 = 10). Some people say that Creation took 7 days, which is half (0.5) of 14. Hematocrit for men is 42-52% (0.42-0.52 volume fraction) and women is 37–47% (0.37-0.47 volume fraction)Ī general rule of thumb is that Hematocrit is three times the Hemoglobin (in US values). Multiply the Hb by 3 for the hematocrit = 45% (If you know an easy way to memorize volume fraction, let us know!)

Multiply the RBCs by 3 to estimate normal Hemoglobin (Hb) = 15 g/dL or multiply the RBCs by 25 to find the SI units = 125 mmol/L There are about 5 (million) RBCs (4.2-6.1 million) The percentages in WBC that make up the whole count vary a little, but as an aid to memorizing them, stick with just ‘average’ numbers. Complete Blood Count (CBC) White Blood Count (WBC) If you know what’s normal, you can easily determine what’s not, so we’ve put together some ways to help memorize some common values. One area where this is especially true is when it comes to lab values. Although the NCLEX rarely offers up any knowledge-based questions, studying for your boards or nursing school exams invariably means a lot of memorization after all, you need to learn the knowledge to apply it. Nursing is all about applying what you know to effectively promote health, prevent illness, and compassionately care for the ill and dying.
