A further sample of blood was taken from the above individual and prepared for haemoglobin analysis. To 18 mls of blood, 2 mls of anticoagulant were added and 5 mls of this sample was centrifuged and a 2.6 ml pellet of red blood cells obtained. 10 mls of water were added and mixed to lyse the cells before a further centrifugation to remove cell membranes from the sample. 1 ml of this sample was further diluted by the addition of 5 mls of water to provide a stock sample of haemoglobin. What was the final dilution factor for this haemoglobin stock solution? O 1.16.76 QUESTION 3 О 2.1.67 О 3.1247 O 4.1.51 O 5.61.89

At the station there is a 2 mL microcentrifuge tube containing sheep blood and 3 tubes containing the following solutions: 0 mM, 300 mM, 600 mM of sucrose. The tubes are randomly labelled A, B, C. 2 mL of each solution were transferred to a different microcentrifuge tube, 20 ul of blood were then added to each tube, and they were mixed well by inverting the tube for multiple times. They were observed and it was determined whether the solution in each tube was hypotonic (Yes or No) relative to the blood cells. In addition, the solutions were diluted with water to help you determine which solution is which sucrose concentration. What sucrose concentration corresponds with each tube? Tube Hypotonic (Yes/No) Hypotonic after 1:1 dilution with water (Yes/No) Most likely Sucrose concentration (mM) A No Yes B Yes Yes C No No
1 ml of whole blood is collected and centrifuged to obtain a plasma sample. The volume of the plasma sample is 300 microlitres. A 1 in 4 dilution of the plasma is made and analysed using a cholesterol assay like the one you performed in the laboratory. 10 microlitres of both the diluted plasma sample and a cholesterol standard are assayed using 1mL of cholesterol reagent. Following incubation at 37 degrees Celcius, the samples are measured spectrophotometrically at 500nm. If the absorbance of the plasma sample assay was 0.5, the absorbance of the cholesterol standard assay was 0.4, and the concentration of cholesterol in the standard was 1.3mM, what was the concentration of the cholesterol in the whole blood (in mM)? (assume all of the cholesterol in the whole blood sample was recovered in the plasma; do not include units in your answer; give your answer to 2 decimal places)

The physician ordered erythromycin 500 mg IV every 8 hours for infection. The pharmacy sends a vial labeled: Erythromycin 1 g. The nursing drug reference provides information to reconstitute 1 g of erythromycin with 20 mL of sterile water and further dilute in 250 mL of 0.9% NS and to infuse over 2 hours. How many ml will you draw from the vial after reconstitution and add it to the IV bag of 0.9% NS 250 mL? 20 mL 5 mL 15 mL 10 mL Page 10 of 14 Previous Page Next Page

A thyroid peroxidase antibody test was performed on a 45 year old man. The dilution sequence was 25 microliters serum to 100 microliters of diluent in tube 1. Then 25 microliters from tube 1 was added to 25 microliters of diluent in tube 2. Then 25 microliters from tube 2 was added to 50 microliters of diluent in tube 3. What is the dilution factor of tube 1. What is the dilution factor in just tube 2. What is the dilution factor in just tube 3. What is the overall dilution factor in tube 3.
You are given a cell stock A. You make a 1:100 dilution and load 10uL diluted sample to a hemocytometer. After counting all 5 "one millimeter squares" you have 51 cells in average. (Please write down each step)T 1. What is the cell concentration of this diluted sample? 2. What is the cell concentration of original cell stock ? 3. If the original stock A has a total volume of 5mL, what is total number of cells in the A? 4. You decide to do a 1:1000 dilution to verify your counting. After loading and counting, you find out that you have 20 cells in average in each square. Do you think the new concentration is consistent with your previous result? If not, list all the possible errors that can cause this inconsistency. MacBook Air
