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: Encouraging family members to press the PCA button for the client is not recommended. The PCA device is designed to be used by the patient to manage their own pain. Allowing someone other than the patient to administer the medication can lead to over-sedation or respiratory depression. The patient must have control over the PCA device to ensure that they are receiving the medication based on their pain level and not someone else's perception of their pain.

Choice B reason: Monitoring the client's respiratory status every 4 hours is important but may not be sufficient for a patient receiving morphine via a PCA device. According to clinical guidelines, respiratory rate, sedation, and pain scores must be recorded more frequently after the initiation of PCA therapy—typically every 15 minutes for the first hour, then every 30 minutes for the next 2 hours, and hourly until 24 hours post-operation. This is to ensure early detection of any adverse effects such as respiratory depression, which is a risk with opioid administration.

Choice C reason: Teaching the client how to self-medicate using the PCA device is the correct action. Patient education is crucial for the effective use of PCA. The patient should be instructed on how to use the device, including when to press the button and the importance of only the patient controlling the button. This empowers the patient to manage their pain effectively and safely, ensuring that they receive the medication when needed and reducing the risk of over-sedation or under-medication.

Choice D reason: Administering an oral opioid for breakthrough pain may be necessary if the PCA does not adequately control the patient's pain. However, this should be done cautiously and typically under the guidance of a pain management team or physician. Breakthrough pain medication is usually reserved for instances where the PCA is not providing sufficient pain relief, and the patient's pain is assessed to be higher than what can be managed by the PCA alone.

Choice A: Rinse your mouth with hydrogen peroxide

Rinsing the mouth with hydrogen peroxide is not recommended for clients with mucositis. Hydrogen peroxide can be too harsh and may cause further irritation to the already sensitive mucosal lining. It is generally advised to use mild rinses such as saline or baking soda solutions.

Choice B: Brush your teeth for 60 seconds twice daily

While brushing is important, it should be done gently with a soft-bristled toothbrush, and the timing should be based on patient tolerance rather than a strict 60-second rule.

Choice C: Floss your teeth gently following each meal

Gentle flossing helps remove food particles and bacteria, reducing the risk of infection. However, if bleeding occurs, the patient should stop and consult a healthcare provider.

Choice D: Wear your dentures only during meals

Wearing dentures only during meals might be advisable for some clients with mucositis, as wearing them all day could irritate the inflamed oral tissues. However, it’s important for the dentures to fit properly and for the client to have periods of rest without the dentures to allow the oral tissues to heal.
