Final answer:
The creatinine clearance (CrCl) for a patient, based on their age, weight, height, and serum creatinine levels, is calculated using formulas like the Cockcroft-Gault formula, but is not provided due to lack of specific information on race or other factors.
Step-by-step explanation:
The question pertains to calculating the creatinine clearance (CrCl) for a 69-year-old female patient who has recently been admitted for a hip replacement. The CCr-corrected formula, which involves the body surface area (BSA), is not provided in the question. However, the basic information to calculate BSA using the DuBois formula, which is BSA (m²) = 0.007184 × Weight(kg)0.425 × Height(cm)0.725, is given. We know that the patient is 5'6" (167.64 cm) and weighs 140lbs (63.5 kg), and we have a serum creatinine (SCr) of 0.7 mg/dL.
One would typically use the Cockcroft-Gault formula to calculate CrCl which is CrCl = [(140 - age) × weight (kg) × (0.85 if female)] / (72 × SCr). For KK, the CrCl calculation would be: CrCl = [(140 - 69) × 63.5 × 0.85] / (72 × 0.7). However, without knowing if KK is of African American descent or other factors that might influence the normal CrCl value, the exact calculation cannot be resolved here.
For reference, normal creatinine clearance values are generally 90-139 ml/min for adult males and 80-125 ml/min for adult females who are less than 40 years old. For those over the age of 40, the values decrease by 6.5 ml/min for each subsequent decade of life.
