The nurse is administering sevelamer during lunch to a client with chronic kidney disease (CKD). The client asks the nurse to bring the medication later. The nurse should describe which action of sevelamer as an explanation for taking it with meals?

Choice A reason: Obtaining a hospital bed with side rails and an over-bed trapeze is not a necessary instruction for reducing the risk of injury for a client taking carbidopa-levodopa, which is a combination of two drugs that increase dopamine levels in the brain and improve motor function in patients with Parkinson's disease. A hospital bed may be helpful for patients with severe mobility impairment or bedridden status, but not for all patients with Parkinson's disease.

Choice B reason: Placing small rugs on smooth surfaces such as tile or wood floors is an incorrect instruction for reducing the risk of injury for a client taking carbidopa-levodopa, which is a combination of two drugs that increase dopamine levels in the brain and improve motor function in patients with Parkinson's disease. Small rugs can pose a tripping hazard and increase the risk of falls, especially for patients with impaired balance or coordination.

Choice C reason: Using caution when changing from a sitting to a standing position is a correct instruction for reducing the risk of injury for a client taking carbidopa-levodopa, which is a combination of two drugs that increase dopamine levels in the brain and improve motor function in patients with Parkinson's disease. Carbidopa-levodopa can cause orthostatic hypotension, which is a sudden drop in blood pressure when changing positions. This can cause dizziness, fainting, or falls. Patients should change positions slowly and carefully, and use support if needed.

Choice D reason: Ambulating using a four point cane or a walker with wheels is not a specific instruction for reducing the risk of injury for a client taking carbidopa-levodopa, which is a combination of two drugs that increase dopamine levels in the brain and improve motor function in patients with Parkinson's disease. The type of assistive device that is appropriate for each patient depends on their individual needs and abilities. Some patients may not need any device, while others may need different types of canes, walkers, or wheelchairs.

Choice A reason: Eliminating use of nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen or naproxen, is an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that stabilizes mood and prevents manic episodes. NSAIDs can increase the blood levels of lithium and cause toxicity, which can manifest as nausea, vomiting, tremors, confusion, or seizures.

Choice B reason: Monitoring blood glucose levels daily is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not affect the blood sugar levels or the risk of diabetes. Blood glucose levels may be important for the general health of the client, but they are not related to lithium therapy.

Choice C reason: Notifying healthcare provider prior to dental procedures is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interact with local anesthetics or antibiotics that may be used during dental procedures. However, the client should inform the dentist about their medical history and medications, as a precaution.

Choice D reason: Avoiding consuming all foods that contain iodine is not an instruction that the nurse should provide to the client who is taking lithium carbonate, which is a medication that does not interfere with the thyroid function or the metabolism of iodine. Iodine is an essential nutrient that is found in many foods, such as seafood, dairy products, eggs, and iodized salt. Avoiding iodine can cause deficiency and lead to goiter or hypothyroidism.
