A nurse is preparing to initiate IV access for an older adult client. Which of the following sites should the nurse select when initiating the IV for this client?

A. Radial vein of the inner arm. This is correct because this site is easily accessible, has good blood flow, and has less risk of complications such as infection, thrombosis, or infiltration.

B. Great saphenous vein of the leg. This is incorrect because this site is not recommended for older adults due to poor circulation, increased risk of thrombophlebitis, and difficulty in monitoring.

C. Dorsal plexus vein of the foot. This is incorrect because this site is prone to edema, infection, and injury, and can interfere with mobility and comfort.

D. Basilic vein of the hand. This is incorrect because this site is more painful, has smaller veins, and can cause nerve damage or occlusion if not inserted carefully.

A. Documenting the client's refusal in the medical record is an important action, but not the first one. The nurse should first try to understand the client's perspective and address any concerns or misconceptions they might have about the blood transfusion. This choice is incorrect.

B. Honoring the client's decision to refuse the blood transfusion is a respectful and ethical action, but not the first one. The nurse should first attempt to educate and persuade the client about the benefits and risks of the treatment, and respect their autonomy only after ensuring that they have made an informed decision. This choice is incorrect.

C. Exploring the client's reasons for refusing the treatment is the first action that the nurse should take. The nurse should use effective communication skills to elicit the client's beliefs, values, fears, and preferences regarding the blood transfusion, and provide factual and evidence-based information to address any knowledge gaps or misconceptions. The nurse should also assess the client's decision-making capacity and determine if they are competent to refuse the treatment. This choice is correct.

D. Discussing the client's refusal with the provider is an appropriate action, but not the first one. The nurse should first try to resolve the issue with the client directly, and involve the provider only if they are unable to do so or if there are legal or ethical implications that require further consultation. This choice is incorrect.
