Ati Predictor/Nclex Study Guide

ATI PREDICTOR/NCLEX STUDY GUIDE CBC (complete blood count) Components Correct Ans - RBC Hbg, Hct, WBC, PLT BMP/CMP Components Correct Ans - NA, K, Ca, Mg, Phos, Creatinine, BUN,Albumin, Glucose Normal RBC count Correct Ans - 4-5.3 million/mm3w What happens to body temp prior to ovulation? Correct Ans - Drops Normal: Hbg (hemoglobin) level Correct Ans - 12-17g/dL Normal Hct level (Portion of RBC/ Plasma) Correct Ans - -33-51% (3x Hbg) -See increase if plasma decreases (even if RBC doesn't increase) -See decrease if over hydrated (even if RBC doesn't decrease) *If someone is bleeding out, they are losing RBC and Plasma equally, so you will not see an initial decline in Hct Normal PLT count Correct Ans - 150,000-450,000/mm3 Normal WBC count Correct Ans - -4,500-11,000/mm3 -Differential or % of each of the 5 types of WBCs which will total 100% -with inflammation (72 hours after) post-OP, see high WBC (NOT infection) What two types of WBC are indicative of infection? Correct Ans - Neutrophils and Eosinophils What is elevated with patients that have chronic "Osis" And "itis?" Correct Ans - Monocytes Normal BUN level; what it shows? Correct Ans - -8-21 -Indicator for hydration -decreased=fluid overload -increased=Dehydration, kidney damage -IF linked at with Creatinine, shows kidney function If albumin is low, and the med you are giving is protein bound, what happens to patient? Correct Ans - Affects them more intensity Normal Creatinine level, meaning? Correct Ans - -0.5-1.2mg/dL (once 25% of nephrons are dead, we see increase) -1.5=50% nephrons dead -waste product of muscle tissue, MORNING labs With Addison's disease do we see increase or decrease in Glucose? Correct Ans - decrease What is the renal threshold for glucose? (at what level will glucose spill into urine?) Correct Ans - 160-190 Are venus blood draws higher or lower than capillary? Correct Ans - 10-15% higher Normal Na level? Correct Ans - 135-145 Normal K level? Correct Ans - 3.5-5 Normal Ca level? Correct Ans - 8.4-10.2 Normal Phos level? Correct Ans - 2.6-4.6 Normal Mg level? Correct Ans - 1.5-2.6 Serum Osmol normal level? Correct Ans - 275-295 (2x Na) Hypertonic solutions Correct Ans - -D5% in .45% (commonly used) -D5% in .9% (commonly used) -3% NaCl (not commonly used) -Dextrose 10% (not commonly used) With hyperaldosteronism what will we see? Correct Ans - Hypernatremia with hypernatremia, what do we see in BP and P? Correct Ans - increase BP and P
