Which instructions should a nurse give to a client prior to obtaining a throat culture?

This is because furosemide is a diuretic that makes you pee more and lose water and electrolytes such as potassium and sodium.

Therefore, you should avoid foods that are high in sodium or potassium, such as bananas, oranges, cranberries, and bagels with cream cheese.

You should also drink plenty of fluids to prevent dehydration.

Choice A is wrong because oatmeal with a banana, milk, and orange juice contains too much potassium, which can cause irregular heartbeat or muscle weakness when taking furosemide.

Choice B is wrong because blueberry muffins, cranberry juice, and herbal tea contain too much sodium and sugar, which can raise your blood pressure and worsen your heart failure.

Choice D is wrong because a bagel with low-fat cream cheese and decaffeinated coffee contains too much sodium and caffeine, which can cause fluid retention and increase your heart rate.

Normal ranges for potassium are 3.5 to 5.0 mmol/L and for sodium are 135 to 145 mmol/L.

You should monitor your electrolyte levels regularly when taking furosemide.
