What is the Cockcroft-Gault equation used to estimate?

Respiratory rate
(140-age) / (72xScr) x weight (kg) (x 0.85 if female)
Blood pressure
Renal function

The correct answer is: Renal function

The Cockcroft-Gault equation is a formula used to estimate renal function by calculating the creatinine clearance of a patient. Creatinine clearance is a measure of how well the kidneys are functioning in terms of filtering waste products from the blood. This equation takes into account the patient's age, weight, and serum creatinine level. Therefore, the correct answer is D - Renal function. Option A, respiratory rate, is not estimated using the Cockcroft-Gault equation. Option B is not correct as well; the formula provided is not the Cockcroft-Gault equation but the MDRD equation used to estimate glomerular filtration rate (GFR). Option C, blood pressure, is not estimated using the Cockcroft-Gault equation either.
