Step by step
Solved in 3 steps
- A uremic patient has a urine output of 1.8 L/24 h and an average creatinine concentration of 2.2 mg/dL. What is the creatinine clearance? How would you adjust the dose of a drug normally given at 20 mg/kg every 6 hours in this patient (assume the urine creatinine concentration is 0.1 mg/mL and creatinine clearance is 100 mL/min)?What is the patient's creatinine clearance given the following data? Serum creatinine 0.6 mg/dL Urine creatinine 102 mg/dL 24 hr urine volume 1650 mL Patient's BSA 1.93 m2 1) 195 mL/min 2) 130 mg/dL 3) 93 mL/min 4) 175 mL/min no references, just homeworkA creatinine clearance is done on a patient with the following results: serum creatinine, 0.6 mg/dL; urine creatinine, 102 mg/dL; urine volume, 1650 mL/24 hours; body surface area, 1.93 m2. Based on the information from calculations above, which of the following is the best interpretation of this patient's creatinine clearance results? 1) Within the normal range 2) Above normal, probably because the 24-hr urine collection was not completed correctly 3) Above normal 4) Below normal no references, just homework

The creatinine clearance of the patient is above reference range. b. The creatinine clearance of the patient is below reference range. c. The creatinine clearance of the patient is within reference range. d. The creatinine clearance of the patient is borderline high.If the shown serial dilutions are performed, starting with a 5M stock of sodium acetate, what is the cumulative dilution in the final tube?

Please show steps, thank you!
- A normal saline solution (0.9 mg of sodium chloride per 100 ml of solution) is given intravenously and a total of 0.5 L of the solution was given over a 4 hour period. What is the flow rate in units of milliliter per hour?. What is the flow rate in units of mg ( of sodium chloride) per hour?. During 4 hour period how much sodium chloride is delivered?750mL is being infused at a rate of 45 gtt/min. The drop factor is 20gtt/mL. How many mL per hour will the patient receive?4) 0.1 ml of a blood sample is added to 9.9 ml of sterile saline.1 ml of this dilution is then added to 9 ml of sterile saline. 1 ml of this dilution is plated , and 37 colonies form. What is the CFU/ml of the blood sample? 5) 5 ml of urine is added to 70 ml of water . 1ml of the diluted urine is plated, and 163 colonies form. What is the CFU/ml of the urine ?
- Calculate the flow rate for a solution of 18 mg in 300 mL with a maintenance dose of 5 mcg/min.1) How to solve for creatinine coefficient with 59kg and 1, 500ml estimated total volume for 24hrs of urine. No gender or age given, but with absorbance reading of 0.082 and concentration of 0.1mg/mL. 2) Also, how to calculate for the creatinine in a urine sample? please formula and solution.A 44-year-old woman was experiencing headaches and fatigue. The consultingphysician recommended testing glucose and electrolytes. The results are attached in the picture below: (a) What is the difference between serum and plasma? (b) Describe the results (c) Plasma glucose levels lower than 20 mg/dl can be fatal. As the patient’s resultsdid not match with her clinical presentation, the consulting biochemist decidedto investigate this test, and found that the glucose analyser was giving theresults in mM, but the lab assistant had assumed the results were in mg/dl. Isthis error pre-analytical, analytical or post-analytical? (d) 1 mM glucose = 18 mg/dL glucose. What is the patient’s fasting plasmaglucose in mg/dL, and is it within the normal range? (e) Describe possible consequences of this error.
