A nurse is caring for a client who has nausea and is vomiting. The nurse should identify that the client is at risk for which of the following acid-base imbalances?

Choice A reason: Caffeinated beverages can cause diarrhea by stimulating the intestinal motility and increasing the fluid loss. They can also irritate the lining of the stomach and intestines.

Choice B reason: Low-fiber cereal is not likely to cause diarrhea. Fiber helps to bulk up the stool and regulate the bowel movements. Low-fiber foods are often recommended for clients with diarrhea to reduce intestinal activity.

Choice C reason: White rice is not likely to cause diarrhea. It is a bland and starchy food that can help to bind the stool and reduce fluid loss. White rice is often part of the BRAT diet (bananas, rice, applesauce, toast) that is suggested for clients with diarrhea.

Choice D reason: Ripe bananas are not likely to cause diarrhea. They are rich in potassium, which can help to replenish the electrolytes lost due to diarrhea. They also contain pectin, a soluble fiber that can help to firm up the stool.

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.
