Correct Answer is ["A","C","D"]
Explanation
Choice A reason:
If Mr. Greene has memory retention and a neurological evaluation that has demonstrated understanding of how to follow the sliding scale and recognize proper dosage, use, and potential side effects of insulin, he is a candidate for self-administration. This ensures he can manage his insulin therapy safely and effectively.
Choice B reason:
If Mr. Greene states “I can do it” but has severe hand tremors, he is not a candidate for self-administration of insulin. Severe hand tremors can impair his ability to accurately draw up and administer the correct dose of insulin, increasing the risk of errors.
Choice C reason:
If Mr. Greene demonstrates the ability to self-administer insulin over a period of time successfully using the “Teach Back” method by a number of staff or visiting nurse, he is a candidate for self-administration. The “Teach Back” method confirms that he understands and can perform the procedure correctly.
Choice D reason:
If Mr. Greene no longer is actively suicidal and has hand-eye coordination that is accurate, he is a candidate for self-administration of insulin. Accurate hand-eye coordination is essential for safely drawing up and administering insulin.
