Correct Answer is B

Explanation

This is the correct way to correct an error on a hand-writen chart, according to the legal and ethical principles of documentation. The PN should also initial and date the correction.

Obliterating the entry or charting in the next column can create confusion and suspicion of tampering with the records. Notifying the charge nurse is not necessary unless the error has serious implications for the client's care or safety

A. Teach the client to use a straw when taking the medication to reduce further tooth staining. B. Reassure the client that this change indicates the medication is having the desired effect. C. Determine if the client is also experiencing mouth or gum pain and difficulty swallowing D. Advise the client to withhold further doses until consulting with the healthcare provider.

Correct Answer is A

Explanation

The correct answer is choicea. Teach the client to use a straw when taking the medication to reduce further tooth staining.

Choice A rationale:

Using a straw when taking liquid iron preparations helps minimize contact with the teeth, thereby reducing the risk of staining.

Choice B rationale:

While tooth discoloration can indicate that the iron is being absorbed, it is not a desired effect and should be managed to prevent cosmetic concerns.

Choice C rationale:

Assessing for mouth or gum pain and difficulty swallowing is important but not directly related to the issue of tooth staining.

Choice D rationale:

Advising the client to withhold doses without consulting a healthcare provider could lead to non-compliance and inadequate treatment of iron deficiency.
