A nurse is planning care for a client who has a newly implanted arteriovenous graft in the right arm. Which of the following actions should the nurse include in the plan of care?

The correct answer is Choice B.

Choice A rationale: This choice suggests that the provider will prescribe a different medication regimen. However, this is not necessarily the case. Rifampin is a first-line medication for tuberculosis and its side effects, including the discoloration of body fluids, are well-known and expected. Therefore, it is unlikely that the provider would change the medication regimen solely based on this side effect.

Choice B rationale: This is the correct answer. Rifampin, an antibiotic used to treat tuberculosis, can cause a harmless red-orange discoloration of body fluids, including urine, sweat, tears, and saliva. This is an expected side effect of the medication and does not indicate any harm or toxicity. It is important for the nurse to reassure the client that this is a normal occurrence and does not require any changes to the medication regimen.

Choice C rationale: This choice suggests that the red-orange discoloration of the client’s saliva may indicate possible medication toxicity. However, this is not accurate. While rifampin can have serious side effects, including liver damage and severe gastrointestinal upset, the discoloration of body fluids is not a sign of toxicity. It is a harmless side effect of the medication.

Choice D rationale: This choice suggests that the client will need to increase her fluid intake to resolve the problem. However, increasing fluid intake will not change the discoloration caused by rifampin. The discoloration is a result of the medication itself and is not influenced by the client’s hydration status.

Applying an ice pack to the client's knee can help reduce inflammation, swelling, and pain after a total knee arthroplasty. The nurse should avoid placing pillows under the client's knee, as this can cause flexion contractures and impair mobility and healing. Massaging or manipulating the incision site can increase pain and risk of infection or bleeding. Range-of-motion exercises are important for recovery, but they should be done with caution and under supervision, not when the client is experiencing severe pain.
