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.)

Answer and Explanation

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 C

Explanation

A. While encouraging relaxation techniques can be helpful, the client’s immediate expression of frustration indicates a need for the nurse to respect their request.

B. Referring the client to a social worker may be beneficial in the long term but does not address the immediate situation.

C. Leaving the client’s room and returning later respects the client's wishes and allows for a more conducive environment for teaching when the client is ready.

D. Explaining the importance of insulin may not be effective if the client is currently unwilling to engage in the discussion.

A. Notify the healthcare provider if the client reports any allergies to iodine or shellfish. B. Instruct the client that it will be necessary to keep the legs straight for 6 to 8 hours after the procedure. C. Encourage the client to drink at least 3 to 4 liters of water prior to the procedure. D. Insert an indwelling urinary catheter prior to going to the x-ray department.

Correct Answer is A

Explanation

A. Notifying the healthcare provider about allergies to iodine or shellfish is crucial, as IVP contrast agents often contain iodine, and allergic reactions can occur. This is a safety measure that can prevent adverse reactions.

B. While keeping the legs straight may be necessary during the procedure, there is no requirement for them to be kept straight for 6 to 8 hours afterward.

C. While hydration is important, the focus should be on hydration after the procedure to help flush out the contrast material rather than specifically drinking large volumes before the procedure.

D. Inserting an indwelling urinary catheter is not routinely required for IVP unless specified by the healthcare provider; preparation usually focuses on the client’s hydration and allergy history.
