An older adult client is receiving digoxin 0.25 mg PO every day, furosemide 40 mg PO twice a day, and potassium chloride 20 mEq PO twice a day. The client remarks, “What a lovely yellow uniform you are wearing today.” The practical nurse (PN) is wearing white. Which action should the PN implement?
Evaluate the client for digitalis glycoside side effects
Withhold the furosemide and force fluids
Assume the client is joking and give the medications
Give the client additional potassium-rich foods
The Correct Answer is A
Choice A reason: Digoxin toxicity can cause visual disturbances, like seeing yellow halos, due to its effect on retinal cone cells. The client’s comment about a yellow uniform suggests this side effect. Evaluating for toxicity, including checking serum digoxin levels, is critical, as toxicity can lead to life-threatening arrhythmias.
Choice B reason: Withholding furosemide and forcing fluids is inappropriate, as the client’s visual symptom points to digoxin toxicity, not furosemide-related issues. Furosemide causes diuresis, but no evidence suggests dehydration here. This choice does not address the likely digoxin-induced visual disturbance.
Choice C reason: Assuming the client is joking ignores a potential digoxin toxicity symptom. Visual changes, like yellow-tinted vision, are serious and require investigation, not dismissal. Administering medications without evaluation risks exacerbating toxicity, making this choice unsafe and incorrect.
Choice D reason: Additional potassium-rich foods are unnecessary, as the client is already receiving potassium chloride. The visual symptom suggests digoxin toxicity, not hypokalemia. Potassium levels may influence digoxin toxicity, but the priority is evaluating digoxin’s effects, not dietary intervention.

Correct Answer is C
Explanation
Choice A reason: Asking the spouse why the client is outside is irrelevant to the clinical concern. Fluoroquinolones cause photosensitivity, increasing sunburn risk. The focus should be on protecting the client from UV exposure, not investigating their location, making this choice unhelpful for addressing the drug’s side effect.
Choice B reason: Notifying the supervisor about an improved condition is premature and unrelated to the client being outdoors. Sitting outside does not indicate recovery, and the priority is addressing photosensitivity from fluoroquinolones, which risks skin damage, making this choice incorrect.
Choice C reason: Fluoroquinolones, like ciprofloxacin, increase photosensitivity by sensitizing skin to UV light, causing severe sunburn or rash. Reminding the client to use sunblock and protective clothing prevents dermal damage during sunlight exposure, directly addressing the drug’s side effect and ensuring safety.
Choice D reason: Encouraging staying indoors is overly restrictive and impractical. Photosensitivity can be managed with sunblock and clothing, allowing safe outdoor activity. This choice unnecessarily limits the client’s mobility, as proper precautions effectively mitigate the risk of UV-related skin damage.
Correct Answer is D
Explanation
Choice A reason: Using an Amsler grid monitors macular degeneration, not sildenafil-related visual changes, which include color tinting or blurred vision due to PDE5 inhibition affecting retinal blood flow. This is not a standard monitoring tool for sildenafil side effects, making it inappropriate for this context.
Choice B reason: Instilling eye drops is irrelevant, as sildenafil’s visual changes are systemic, caused by its effect on retinal phosphodiesterase, not a local eye condition treatable with drops. No evidence supports eye drops for this side effect, making this choice incorrect and ineffective.
Choice C reason: Wearing dark glasses may reduce light sensitivity but does not address sildenafil’s visual side effects, like blue-green color distortion, caused by altered retinal signaling. This is a temporary, drug-induced effect, and glasses do not mitigate the underlying issue, making this choice inadequate.
Choice D reason: Reporting visual changes immediately is critical, as sildenafil can cause rare but serious effects like non-arteritic anterior ischemic optic neuropathy, impairing retinal blood flow. Prompt reporting allows the provider to assess severity, adjust dosing, or discontinue the drug to prevent permanent vision loss.
