She is 6 hours post-operative and will be staying on your unit for the next 24 hours. You collect her VS: BP 148/90, HR 82, RR 16, BMI 38. Her labwork consists of the following values: CBC is WNL, cholesterol 282, HDL 38, LDL 170, triglycerides 280, FBG 170. labwork consists of the following values: CBC is WNL, cholesterol 282, HDL 38, LDL 170, triglycerides 280, FBG 170....
