- A 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 homeworkA 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)?Your laboratory supervisor asks you to determine a patient’s 24-hour creatinine clearance. The urinesample reported on the laboratory report is 580 mL. The plasma creatinine level is reported as 10 mg/L.In addition, the urine creatinine concentration was 820 mg/L.Use the information in the case and determine the 24-hour creatinine clearance of this patient. Takeinto consideration the 24-hour duration.

One of you per group will be on his/her normal fluid intake for 24 hours prior to ingesting the test volume of water [normal hydration - water loaded). B. One of you per group will be on his/her normal fluid intake for 24 hours prior to ingesting the test volume of 0.9% NaC1 [normal hydration - saline loaded]. C. One of you per group will be over-hydrated by drinking 2 ml of tap water per kilogram body weight per hour in addition to your normal fluid intake during the previous 24 hours (awake) before ingesting the test volume of water in lab [over-hydration - water loaded]. D. One of you per group before drinking a test volume load of water will be partially dehydrated by abstaining from fluids during the previous 24 hours, except for one cup of coffee, tea, milk or soft drink at the evening meal and at breakfast. No additional fluids should be taken up to the time of the experiment. Breakfast and lunch can be eaten but they should be low in protein [dehydrated, water loaded).…
- Well 1 contains 20 uL of serum. Wells 2-6 contain 90 uL of water. To do a serial dilution of 10% concentration (not volume) for each dilution, how many uL of liquid do you move between each well? Type your answer as a whole number of uL, but do not type the "uL" label. Hint: see end of video.A 65 kg patient is diagnosed with a stemi is to receive an IV bolus dose of abciximab 0.25mg/kg followed by a maintenance infusion of the drug at the rate of 0.125mcg/kg/min. The abciximab is available in 5mL vials containing 2mg/mL. a) How many mL will you administer for the bolus? b) How many mcg/min will the patient receive during the maintenance infusion?The practical nurse (PN) administers an antibiotic to a client with a respiratory tract infection.
