A nurse is teaching about food choices to a client who has chronic kidney disease and must limit potassium intake. Which of the following choices should the nurse recommend as containing the least potassium?

Choice A reason: Instructing the client to expect tingling in their extremities is not a standard post-lumbar puncture care instruction. Tingling may be a sign of nerve irritation or damage, which is not an expected outcome and should be reported if it occurs.

Choice B reason: Measuring blood glucose every 2 hours is not related to post-lumbar puncture care unless the client has a specific condition that requires such monitoring. Post-lumbar puncture care focuses on preventing complications such as headaches and monitoring for signs of infection or bleeding.

Choice C reason: Limiting the client's fluid intake is not advised following a lumbar puncture. In fact, increasing fluid intake can help prevent the occurrence of post-lumbar puncture headaches, which are a common complication. Adequate hydration helps replenish cerebrospinal fluid and reduce headache severity.

Choice D reason: Instructing the client to lie flat is the correct action. After a lumbar puncture, it is recommended that the client lies flat for several hours to prevent the leakage of cerebrospinal fluid from the puncture site, which can lead to a spinal headache. Lying flat helps maintain normal cerebrospinal fluid pressure and reduces the risk of headache.

Choice A reason: While it is generally advised to avoid taking blood pressure readings from an arm with a PICC line to prevent complications, if the right arm cannot be used, as may be the case with the other clients listed, the nurse may have to use the left arm with extreme caution, ensuring not to disrupt the PICC line.

Choice B reason: Bell's palsy affects facial nerves and does not typically impact the measurement of blood pressure. Therefore, there is no contraindication to using the left arm for a blood pressure reading in a client with left-sided Bell's palsy.

Choice C reason: A client with right-sided weakness due to Parkinson's disease can have their blood pressure taken on the left side if the right side is too weak to provide an accurate reading or if using the right side would cause discomfort to the client.

Choice D reason: For a client with a right upper extremity arteriovenous fistula, typically created for dialysis access, blood pressure measurements should not be taken on that arm to avoid damaging the fistula. Therefore, the left arm should be used for blood pressure readings in this case.
