Correct Answer is ["250"]

Explanation

The correct answer is 250 mg.

Step 1: Convert grams to milligrams. 1 gram = 1000 milligrams. So, 2 grams = 2000 milligrams.

A. Tell the client the physician wants the client to take the medicine. B. Explain the purpose for the medication. C. Ask the client why they are being difficult. D. Document that the client refuses the medication.

Correct Answer is D

Explanation

Choice A rationale:

Telling the client that the physician wants them to take the medicine may not address the client’s concerns or fears about the medication.

Choice B rationale:

Explaining the purpose of the medication is important, but it does not directly address the client’s refusal.

Choice C rationale:

Asking the client why they are being difficult could escalate the situation and is not a respectful or therapeutic response.

Choice D rationale:

Documenting that the client refuses the medication is the most appropriate action as it accurately records the client’s decision and can inform future care planning.
