Final answer:
The statement requiring further teaching is the patient's intention to use salt substitutes, as they could contribute to excessive potassium intake. Proper IV solution preparation involves dilution calculations. Patients on potassium replacement therapy should carefully monitor their potassium levels, especially when taking other medications like NSAIDs.
Step-by-step explanation:
The subject of this question revolves around understanding the precautions and guidance provided to a patient who is being discharged on oral potassium replacement therapy. Among the statements given by the patient, the one that indicates the need for further teaching by the nurse is "I will continue to use salt substitutes to flavor my food." This is of concern because most salt substitutes contain potassium chloride and could potentially lead to hyperkalemia when combined with potassium supplements. The patient should be educated on the proper management of potassium intake through diet and medication.
When it comes to making an intravenous (IV) delivery of 0.5% KCl for a patient with hypokalemia, it's not as simple as taking a pre-made IV bag from the supply cabinet. Instead, an aide would need to prepare the correct dilution using a sterile solution and a concentrated stock solution of KCl, performing a dilution calculation to reach the desired concentration.
If the nurse is discharging a patient on furosemide, a diuretic, it's commonly prescribed for conditions like hypertension, where it acts on the loop of Henle and inhibits the reabsorption of Na+ and Cl-, effectively reducing blood pressure. Concurrently, taking nonsteroidal anti-inflammatory medications occasionally for arthritis pain could affect kidney function and alter potassium levels, which warrants caution. Furthermore, the patient is advised to read food labels for added potassium to ensure that they are maintaining the correct dietary balance of this mineral, with the recommended daily potassium intake being 4700 mg.
