A nurse is preparing to insert an indwelling urinary catheter for a client. Which of the following actions should the nurse plan to take?

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: Memory loss is not typically associated with a lack of dietary fiber. Memory loss can be related to various neurological or psychological conditions.

Choice B reason: Bleeding gums are commonly associated with vitamin C deficiency, not a lack of dietary fiber.

Choice C reason: Brittle hair can be associated with poor nutrition in general, but it is not a specific indicator of inadequate fiber intake.

Choice D reason: Constipation is a well-known symptom of inadequate fiber intake. Fiber helps to bulk up the stool
and promotes regular bowel movements.
