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 D
Explanation
A. Instructing the client to increase protein intake is inappropriate, as jaundice may indicate liver dysfunction, which can affect protein metabolism.
B. Preparing the client for repeat blood cultures may be necessary if there is suspicion of an infection, but the priority is to assess the liver's function first due to the presence of jaundice. C. Arranging emergency transport to an inpatient facility is not immediately necessary unless the client shows signs of severe distress or complications. Evaluation of liver function is a more prudent first step.
D. Explaining the need to evaluate liver function is critical because jaundice indicates a potential liver issue that needs immediate assessment. This evaluation will guide further treatment and management.
