A client with multiple sclerosis (MS) is receiving interferon beta-Ib 0.1875 mg subcutaneously every other day. The nurse reconstitutes the vial by slowly injecting 2 mL of diluent into the interferon vial for a reconstituted solution of 0.25 mg/1 mL. How many mL should the nurse administer? (Enter numeric value only. If rounding is required, round to the nearest hundredth.)
The Correct Answer is ["0.75"]
To determine the correct dosage, the nurse should use the concentration of the reconstituted solution which is 0.25 mg per 1 mL. Since the prescribed dose is 0.1875 mg, the nurse needs to calculate the volume of the reconstituted solution that contains this dose. By dividing the prescribed dose (0.1875 mg) by the concentration of the solution (0.25 mg/mL), the result is the volume to administer. Therefore, the nurse should administer 0.75 mL of the reconstituted solution.

Correct Answer is A
Explanation
A. Depletion of clotting factors occurs in DIC as the coagulation cascade is activated, leading to the formation of clots and subsequent consumption of clotting factors, which can result in bleeding.
B. Activation of complement pathways is part of the immune response but does not directly explain the coagulopathy seen in DIC.
C. Production of extra platelets may occur, but in DIC, platelets are consumed more rapidly than they can be produced, contributing to bleeding risks.
D. Inhibition of red blood production is not directly related to the coagulation issues seen in DIC; rather, it relates more to the overall effects of shock and organ dysfunction.
