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?

The correct answer is B. Decreased deep tendon reflexes. Hyperkalemia can lead to muscle weakness and decreased reflexes, which is a common manifestation in patients with chronic kidney disease.

Choice A reason:

Wheezing is typically associated with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD), not hyperkalemia. Hyperkalemia affects the muscular function and cardiac conduction rather than causing respiratory symptoms.

Choice B reason:

Decreased deep tendon reflexes occur due to the effect of hyperkalemia on the neuromuscular junction and muscle excitability. In hyperkalemia, the resting membrane potential of muscle cells is less negative, which makes them less responsive to stimuli.

Choice C reason:

Hypoactive bowel sounds are generally associated with gastrointestinal issues and are not a direct manifestation of hyperkalemia. While severe hyperkalemia can affect smooth muscle function, it is not typically characterized by changes in bowel sounds.

Choice D reason:

Cerebral edema is not a manifestation of hyperkalemia. It is usually caused by traumatic brain injury, infections, or other neurological conditions. Hyperkalemia primarily affects muscular function and cardiac conduction.

Normal serum potassium levels range from about 3.5 to 5.0 mmol/L. Hyperkalemia is defined as serum potassium levels above 5.0 mmol/L.

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.
