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.)

Answer and Explanation

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 B

Explanation

B. When purulent drainage is observed at a wound site, obtaining a culture of the drainage is essential for identifying the specific microorganisms causing the infection and determining their sensitivity to antibiotics.

A. Serum blood glucose level is not directly relevant to the assessment of purulent drainage at a wound site.

C. An elevated CRP level may indicate the presence of infection but obtaining a CRP level may not be as immediate or specific as obtaining a wound culture.

D. Blood pH level is not directly relevant to the assessment of purulent drainage at a wound site.

A. Review with the client the need to avoid foods that are rich in milk and cream. B. Reinforce the teaching by asking the client to make a list of snack foods high in dairy content. C. Remind the client that it is also important to switch to decaffeinated coffee and tea. D. Suggest that the client also plan to eat frequent small meals to reduce discomfort.

Correct Answer is A

Explanation

A. Consuming dairy products, especially those rich in milk and cream, can stimulate gastric acid secretion and exacerbate symptoms of a duodenal ulcer. Therefore, it is essential for the nurse to review with the client the importance of avoiding foods that can aggravate the ulcer and worsen symptoms.

B. While reinforcing teaching about dietary modifications is important, encouraging the client to make a list of snack foods high in dairy content would not address the issue of avoiding dairy products to protect the duodenal ulcer.

C. While switching to decaffeinated coffee and tea can be beneficial for individuals with duodenal ulcers, it does not directly address the client's misconception about using dairy products to coat and protect the ulcer.

D. Eating frequent small meals can help reduce discomfort associated with duodenal ulcers by minimizing gastric acid secretion and preventing large fluctuations in stomach volume.

However, this option does not address the client's misconception.
