Final answer:
PhosLo is a medication used in patients with chronic kidney disease to lower abnormal levels of phosphates in the blood, known as hyperphosphatemia, thus impacting phosphorus levels.
Step-by-step explanation:
The nurse preparing to administer a dose of PhosLo to a patient with chronic kidney disease would interpret that this medication should have a beneficial effect on phosphorus levels in the patient. PhosLo is used to treat hyperphosphatemia, which is an abnormally increased level of phosphates in the blood, often seen in patients with decreased renal function or chronic kidney disease. Since PhosLo contains calcium acetate, when it binds with dietary phosphate, it forms insoluble calcium phosphate, which is excreted from the body, thereby helping to lower the serum phosphate levels.
