THANKS IN ADVANCE!!

An intravenous dose of azithromycin is usually prepared by injecting a measured small amount of sterile water into a sealed vial containing a specific known amount of solid formulation containing the medication and shaking the vial until all of it is dissolved. The dosage to be administered to a patient is then removed (with a syringe) and added to a specific volume of diluent solution, which is then administered as an IV drip. A diluent solution that is commonly used is saline (0.45% sodium chloride solution).

According to the nursing notes, at least 36 minutes passed before the hospital staff realized something was wrong. Azithromycin is usually administered intravenously over a concentration range of 1.0-2.0 mg/mL over a period of one hour. Consider a hypothetical situation whereby a dose of 500 mg of azithromycin is administered at 2.0 mg/mL of azithromycin in saline.

a) How many mg of medicine would have been administered every 15 minutes? (Your answer should be a whole number.) รขย€ยจ

b) What % of medication(relative to the total dose of 500mg) would be administered by 36 minutes? (Your answer should be a whole number.) รขย€ยจ

c) How much saline solution (in mL) would have been administered for a dosage of 500 mg in 36 minutes? (Your answer should be a whole number.)

8- in an emergency when there is insufficient time for normal pretransfusion testing which of the following should be issued without waiting for the results of a crossmatch?

* O Rh (D) Positive whole blood.

* O Rh (D) Positive packed cells.

* O Rh (D) Negative whole blood.

9- A patient presents for a 4 unit crossmatch. The patients blood group is AB Rh (D) Positive. You have the following units of blood available. 10 units of group O Rh (D) Positive, 6 units of group O Rh (D) Negative, 8 units of A Rh (D) Postive units. What units would you select for the crossmatch?

* Do another ABO Rh check. If the same, report.

* Wash the cord blood cells in saline, and then repeat the groups.

* Check the maternal and paternal blood groups.
