The healthcare provider prescribes interferon beta-1b 0.125 mg every other day for a client with multiple sclerosis. The nurse reconstitutes the single-use vial of powder labeled, "0.3 mg with 2 mL of sterile water." How many mL should the nurse administer to the client? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.8"]
The vial contains 0.3 mg of medication, which has been reconstituted with 2 mL of sterile water. Therefore, each milliliter of solution contains 0.15 mg of medication.
The prescribed dose is 0.125 mg, so the nurse should administer \( \frac{0.125\ mg}{0.15\ mg/mL} = 0.8333 \) mL of the solution.
After rounding to the nearest tenth, the nurse should administer 0.8 mL of the reconstituted solution to the client every other day.

Correct Answer is C
Explanation
C. After eye surgery, especially when there's been trauma like glass removal, it's crucial to protect the eye from further injury, particularly during sleep when movements may be involuntary and less controlled. An eye shield helps prevent inadvertent rubbing or trauma to the eye, promoting healing and reducing the risk of complications.
A. While deep breathing and coughing exercises are important for preventing respiratory complications after surgery, they are not the immediate intervention required following surgical removal of glass from the eye.
B. Monitoring vital signs is essential for assessing the client's overall health status and detecting any signs of complications. However, it is not a priority
D. While administering eye drops may be a part of postoperative care, it's not the immediate intervention required right after the surgical removal of glass from the eye.
Correct Answer is D
Explanation
D. The correct instruction to include in a discharge teaching plan for an adult client with hypernatremia is to review food labels for sodium content. Hypernatremia is a condition characterized by high levels of sodium in the blood, and it is often due to fluid loss rather than excessive sodium intake.
A. Hypernatremia is characterized by elevated levels of sodium in the blood, and reducing sodium intake is typically part of the treatment plan. Instructing the client to use salt tablets would exacerbate the hypernatremia and could lead to further complications.
B. This instruction is not directly related to managing hypernatremia. While monitoring urine output is important for assessing hydration status and kidney function, it may not specifically address the underlying cause of hypernatremia.
C. Hypernatremia is often caused by dehydration or inadequate water intake, leading to elevated sodium levels in the blood. Therefore, hydrating is an important instruction but not the most important.
