A nurse is reinforcing teaching with a client who is at risk for hypokalemia. The nurse should instruct the client that which of the following foods is the best source of potassium?

Spinach

Baked potato

Banana

Cheese

Answer and Explanation

The Correct Answer is B

Choice A reason: Spinach is a good source of potassium, but not the best. According to the USDA, one cup of cooked spinach contains 839 mg of potassium, which is about 18% of the recommended daily intake (RDI) for adults².

Choice B reason: Baked potato is the best source of potassium among the choices. According to the USDA, one medium baked potato with skin contains 941 mg of potassium, which is about 20% of the RDI for adults². Potassium is an essential mineral that helps regulate fluid balance, nerve and muscle function, and blood pressure.

Choice C reason: Banana is a popular source of potassium, but not the best. According to the USDA, one medium banana contains 422 mg of potassium, which is about 9% of the RDI for adults².

Choice D reason: Cheese is a poor source of potassium. According to the USDA, one ounce of cheddar cheese contains only 28 mg of potassium, which is less than 1% of the RDI for adults². Cheese is high in sodium, which can counteract the benefits of potassium and increase the risk of hypertension.

Correct Answer is A

Explanation

The correct answer is: A. Place the client on continuous cardiac monitoring.

Choice A reason:

Placing the client on continuous cardiac monitoring is crucial because metabolic alkalosis can lead to life-threatening arrhythmias due to electrolyte imbalances, particularly hypokalemia. Continuous monitoring allows for the early detection and management of these arrhythmias, ensuring patient safety.

Choice B reason:

Obtaining a prescription for insulin is not relevant for treating metabolic alkalosis. Insulin is typically used for managing hyperglycemia and diabetic ketoacidosis, not for correcting alkalosis.

Choice C reason:

Planning to administer sodium bicarbonate is incorrect because sodium bicarbonate is used to treat metabolic acidosis, not alkalosis. Administering it in this context could worsen the alkalosis.

Choice D reason:

Having the client breathe into a paper bag is a technique used for respiratory alkalosis to increase CO2 levels. It is not appropriate for metabolic alkalosis, which requires different management strategies.

A. Metabolic alkalosis B. Respiratory acidosis C. Respiratory alkalosis D. Metabolic acidosis

Correct Answer is B

Explanation

Choice A reason: Metabolic alkalosis is a condition in which the blood pH is elevated due to an excess of bicarbonate or a loss of acid. It can be caused by vomiting, diuretics, or excessive antacid intake. It is not associated with COPD.

Choice B reason: Respiratory acidosis is a condition in which the blood pH is lowered due to an accumulation of carbon dioxide. It can be caused by hypoventilation, airway obstruction, or lung diseases such as COPD. It is the most common acid-base imbalance in COPD patients.

Choice C reason: Respiratory alkalosis is a condition in which the blood pH is elevated due to a loss of carbon dioxide. It can be caused by hyperventilation, anxiety, fever, or aspirin overdose. It is not common in COPD patients.

Choice D reason: Metabolic acidosis is a condition in which the blood pH is lowered due to an excess of acid or a loss of bicarbonate. It can be caused by diabetic ketoacidosis, renal failure, or lactic acidosis. It is not directly related to COPD.
