A nurse is planning care for a client who reports heartburn. Which of the following tests should the nurse anticipate in the client's plan of care?

Choice A reason: Caffeinated beverages can cause diarrhea as caffeine stimulates the gastrointestinal tract and can

lead to increased bowel movements.

Choice B reason: Ripe bananas are typically recommended to manage diarrhea due to their pectin content, which can help absorb liquid in the intestines.

Choice C reason: White rice is often recommended for those with diarrhea as it is easy to digest and can help form

stools.

Choice D reason: Low fiber cereal is less likely to cause diarrhea compared to high fiber options, as fiber can accelerate the passage of food through the intestines.

Choice A reason: Magnesium is important for many processes in the body, including nerve transmission and the regulation of muscle contractions, but it is not primarily used for oxygen transport.

Choice B reason: Iron is a key component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. The normal range for iron in the blood is typically 50 to 170 micrograms per deciliter for men and 65 to 165 micrograms per deciliter for women.

Choice C reason: Potassium is crucial for heart function and plays a key role in skeletal and smooth muscle contraction, making it important for normal digestive and muscular function, but not directly for oxygen transport.

Choice D reason: Phosphorus helps form bones and teeth and is involved in the body's utilization of carbohydrates and fats, as well as the synthesis of protein for the growth, maintenance, and repair of cells and tissues, but it does not transport oxygen.
