A nurse is caring for a client who has lung cancer and has a sealed radiation implant. Which of the following actions should the nurse take? (Select all that apply)

Choice A reason: A single light fixture along the sidewalk provides limited illumination, insufficient for comprehensive safety. Multiple, evenly spaced lights are needed to prevent falls, especially for older adults. Inadequate lighting increases risks of trips or assaults, indicating the client’s understanding of outdoor safety is incomplete and does not fully address home safety needs.
Choice B reason: Changing smoke alarm batteries annually ensures functional alarms, reducing fire-related mortality by 50%. Regular maintenance supports early smoke detection, enabling timely evacuation or response. This action reflects a strong understanding of fire safety, a critical home safety component, making it the best indicator of the client’s safety awareness.
Choice C reason: A small area rug at the front door poses a tripping hazard, particularly for those with mobility issues. Loose rugs can lead to falls, causing injuries like fractures. This finding suggests the client does not fully understand fall prevention, a key aspect of home safety, making it an incorrect indicator of safety awareness.
Choice D reason: Securing electrical cords under furniture risks fire hazards if cords are damaged or pinched, potentially causing electrical shorts. Cords should be secured along walls or with covers to prevent tripping without compromising safety. This indicates a misunderstanding of electrical safety, increasing fire or injury risks, and is not a correct safety measure.

Choice A reason: Advising over-the-counter medications as safe is incorrect, as many, like NSAIDs, increase warfarin’s bleeding risk by inhibiting platelets or affecting liver metabolism. Warfarin’s narrow therapeutic index requires careful management to prevent hemorrhage, making broad safety claims dangerous without specific evaluation.
Choice B reason: Consulting the pharmacist identifies interactions with warfarin, a vitamin K antagonist metabolized by CYP450 enzymes. Many drugs alter warfarin’s efficacy, risking thrombosis or bleeding. Pharmacist expertise ensures safe polypharmacy, maintaining therapeutic INR levels critical for managing pulmonary emboli effectively.
Choice C reason: Recommending warfarin with other medications ignores interaction risks and timing needs. Warfarin’s absorption is unaffected by timing, but CYP450 interactions can alter INR. This advice is irrelevant to safety, missing the need for individualized regimen assessment to prevent complications in anticoagulation therapy.
Choice D reason: Cranberry juice may enhance warfarin’s effect by inhibiting CYP2C9, increasing INR and bleeding risk. Advising its use without monitoring is unsafe, as dietary factors can destabilize anticoagulation, potentially causing hemorrhage in clients with pulmonary emboli, requiring careful dietary guidance.
