Final answer:
Patients with a history of renal stones on thiazide and loop diuretics should have their urine composition monitored through a 24 hour urine collection, and be observed for any kidney stone symptoms, such as severe pain or hematuria.
Step-by-step explanation:
Monitoring for Patients on Thiazide and Loop Diuretics
When monitoring a patient with a history of renal stones who is on thiazide and loop diuretics, you should pay attention to several key factors. These medications affect the reabsorption of Na+ and Cl- ions in the kidneys, which can alter the patient's electrolyte balance and urine composition. Hence, monitoring should include a 24 hour urine collection to measure total daily urinary volume and the excretion of magnesium, sodium, uric acid, calcium, citrate, oxalate, and phosphate.
Additionally, it's essential to monitor the patient for any signs of kidney stone symptoms, which can include severe pain ('loin to groin'), hematuria, and possible nausea and vomiting. Understanding the patient's full medical history is also important, as conditions like hyperparathyroidism or renal tubular acidosis can contribute to the formation of calcium phosphate stones, a specific type of renal stone.
