A nurse is caring for a client who has an electrolyte imbalance with a potassium level of 6.4 mEq/L. Which of the following should the nurse administer?

A) A potassium supplement: Administering a potassium supplement would be inappropriate for a client with a potassium level of 6.4 mEq/L. This level is above the normal range (3.5-5.0 mEq/L) and indicates hyperkalemia, which can have serious effects on cardiac function. Increasing potassium intake could exacerbate the condition.

B) A fiber supplement: While fiber supplements can be beneficial for overall digestive health, they do not directly address or correct an electrolyte imbalance like hyperkalemia. They are not relevant in managing elevated potassium levels.

C) An anticonvulsant: Anticonvulsants are used to manage seizure activity and are not indicated for treating hyperkalemia. They do not have any role in the regulation or management of potassium levels in the body.

D) A diuretic: Diuretics, particularly loop diuretics, are often used to help manage hyperkalemia by promoting the excretion of potassium through urine. This helps lower the elevated potassium levels in the blood and reduce the risk of complications such as cardiac arrhythmias. Therefore, administering a diuretic is an appropriate intervention for a client with a potassium level of 6.4 mEq/L.

A) Consume a diet low in cholesterol: A diet low in cholesterol is beneficial for preventing cholelithiasis (gallstones), as high cholesterol levels can contribute to the formation of cholesterol stones in the gallbladder. By reducing dietary cholesterol, the risk of gallstone formation can be minimized.

B) Increase your intake of refined carbohydrates: Increasing the intake of refined carbohydrates can lead to higher levels of triglycerides and cholesterol in the blood, which can promote the formation of gallstones. This dietary change is not recommended for preventing cholelithiasis.

C) Consume a diet high in calories: A high-calorie diet, especially if it leads to obesity, increases the risk of developing gallstones. Obesity is a significant risk factor for cholelithiasis, and a high-calorie diet can contribute to weight gain and the development of gallstones.

D) Reduce your dietary fiber intake: Dietary fiber helps in reducing cholesterol levels by binding bile acids in the intestines, which in turn can prevent the formation of cholesterol gallstones. Reducing fiber intake would be counterproductive and increase the risk of cholelithiasis.
