A nurse is assisting with the care of a client who is receiving an IV infusion of dextrose 10% in water. The nurse should monitor the client for which of the following adverse effects?

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.

Choice A reason: Aluminum-containing antacids are more likely to cause constipation rather than diarrhea.

Choice B reason: Magnesium-containing antacids can cause diarrhea because magnesium can act as an osmotic laxative, drawing water into the intestines and increasing peristalsis.

Choice C reason: While antibiotics can disrupt the gut flora and potentially cause diarrhea, they are not the best
answer when compared to magnesium-containing antacids specifically known for this side effect.

Choice D reason: Anticholinergics/antispasmodics typically reduce gastrointestinal motility, which would more likely lead to constipation instead of diarrhea.

Choice E reason: Opioid narcotics are known to cause constipation due to reduced gut motility, not diarrhea
