- Prepare 50 plates of Sheep's Blood Agar using 100mm petri dish. Add 10% of blood to the media. (Manufacturer's instructions: Suspend 38 g of blood agar base dehydrated powder in 1 liter of distilled or deionized water.) Pour 25 mL of prepared medium per plate. Express answer to the nearest whole number. How many grams of the dehydrated powder should be weighed? Answer: What is the volume of distilled water that should be used in the preparation? Answer: What is the volume of sheep's blood that should be added to the sterilized and cooled blood agar base? Answer:A nurse reconstituted a vial of 750 mg Cefuroxime Sodium Powder for Injection with 6mL of sterile water for injection. The reconstituted solution was dark amber-colored solution. The package insert states that solution colors range from clear to yellow depending on concentration, diluent, and storage conditions. The nurse was then hesitant to give the patient the solution due to its unusual dark color. Five portions were taken from a batch of cefuroxime sodium. Prior to testing in the instrument, each part was subjected to one of the following conditions: Conditions Specifications Temperature Portion 1: 8°C ± 2°C Portion 2: 30°C ± 2°C Portion 3: 40°C ± 2°C Light Portion 4: Kept in the dark Portion 5: Exposed to direct sunlight 1. Which form of the product – the powder for injection, the reconstituted product, or both – will you subject to the following conditions? Why do you think these forms can best address the problem?Gel used in electrophoresis is/are: a. Agarose gel b. Polyacrylamide plain gel c. Polyacrylamide SDS impregnated Polyacrylamide gel (Sodium dodecyl sulphate)
