What is the priority nursing care for a client who is prescribed hydroxychloroquine (Plaquenil)?

The priority nursing care for a client prescribed hydroxychloroquine is to assess for blurred vision. Hydroxychloroquine is known to potentially cause retinal toxicity, which can lead to vision changes including blurred vision. Regular assessment of visual acuity and monitoring for any changes in vision are crucial, especially since these side effects can be irreversible if not caught early.

The importance of this assessment lies in the fact that early detection of any adverse effects related to vision can prompt timely intervention, thereby preserving the client’s sight. It reflects the nursing responsibility to safeguard the client's overall well-being and address any significant side effects related to medications administered.

While monitoring for headaches, educating on dietary restrictions, and checking for skin reactions are all relevant nursing considerations, they do not address the immediate risk associated with hydroxychloroquine. Visual disturbances can have profound implications for a client’s daily function and quality of life, underscoring the rationale for prioritizing the assessment for blurred vision above other concerns.
