A client with multiple sclerosis (MS) is receiving interferon beta-1b 0.1875 mg subcutaneously every other day. The nurse reconstitutes the vial by slowly injecting 1.2 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"]
Calculate the volume of the reconstituted solution that contains the prescribed dose of 0.1875 mg. Since the reconstituted solution has a concentration of 0.25 mg per 1 mL, we can set up a proportion to find the answer: (0.1875 mg / X mL) = (0.25 mg / 1 mL).
Solving for X gives us X = (0.1875 mg * 1 mL) / 0.25 mg, which equals 0.75 mL.
Therefore, the nurse should administer 0.75 mL of the reconstituted solution.

Explanation
Client Statement: A. The client seems unemotional when talking about needing to rebuild her house.
Suppression fits here because the client appears detached or unemotional when discussing the significant emotional task of rebuilding her house after it collapsed. This suggests a deliberate effort to suppress or minimize the emotional impact of the situation.
Client Statement: C. The client discusses moving to Hawaii instead of returning to rebuild her house.
The client's discussion of moving to Hawaii instead of facing the reality of rebuilding her house reflects a form of fantasy. It suggests a retreat into an idealized scenario (moving to a distant, idyllic location) to avoid dealing directly with the trauma and stress associated with rebuilding her home.
Client Statement: B. The client says that she sometimes forgets why she is in the hospital.
Isolation can be inferred here because the client's statement about forgetting why she is in the hospital may indicate a psychological distancing or detachment from the traumatic events that led her there. It suggests a coping mechanism where she separates her emotional distress (related to the house collapse) from the practical reality of being hospitalized and receiving treatment.
Client Statement: D. The client is frightened that the hospital will burn down.
This statement fits into the defense mechanisms of fantasy. The client encounters thoughts of the hospital burning and her house burns down.
Correct Answer is A
Explanation
Rationale
A. An elevated neutrophil count suggests an active immune response to infection, supporting the clinical findings of purulent drainage. This information is crucial for the healthcare provider to assess the severity of the infection and guide treatment.
B. Hematocrit changes are more related to blood volume, fluid shifts, or bleeding rather than infection. While it may be monitored postoperatively, it does not provide specific information about infection.
C. Platelet count is important for assessing clotting function but does not directly indicate infection or purulent drainage.
D. Serum sodium levels are part of electrolyte balance and hydration status monitoring but do not directly relate to the presence of infection.
