Consider a drug which is exogenous to the body. The drug is filtered, but not secreted, reabsorbed, or metabolised by the kidneys. The drug is constantly infused in a patient to maintain a plasma concentration of 2mg/L. 24 hour urine collection shows the drug being excreted at a rate of 400µg/min. What is this patient's GFR? 50ml/min 100ml/min 150ml/min 200ml/min O 400ml/min

A patient comes to your medical practice with complaints of low urine output (not peeing). You use inulin to calculate the glomerular filtration rate (GFR) using the following information: Plasma level (P – constant over 24 hours): 10 mg/mL inulin. Urine sample (U): 144 mg inulin/mL urine. Urine formation (V): 10 mL/min. Using the fromula GFR=V ✕ U/P, you calculate a GFR of ... A) 144mL/min.. B) 14400 mL/min. C) 144 min./mL. D) 144 g mannitol/min.
A 68-year old woman presents with hypertension and oliguria. A CT of the abdomen reveals a hypoplastic left kidney. based on the following laboratory data which of the following is her estimated RPF? Renal artery p-amino hippuric acid (PAH) = 6mg/dL Renal vein PAH = 0.6mg/dL urinary PAH = 25mg/mL urine flow= 1.5mL/min hematocrit = 40%
A 24hr increase of GFR from 90ml/min to 120 ml/min because of a change of filtration fraction from 0.15 to 0.2 with no change of 24 hr water and sodium intake is expected to cause the following: O A. Decrease renal oxygen consumption OB. Decrease body water OC. Decrease renal plasma flow OD. Decrease volume of urine
Use this paragraph to answer the following 2 questions. To evaluate kidney function in a 45-year-old woman with type Il diabetes, you ask her to collect her urine over 24 hours. She collects 3600 ml of urine in that period. The clinical laboratory returns the following results after analysing the patient's urine and plasma samples: plasma creatinine 4 mg/dL, urine creatinine 32 mg/dL, plasma potassium 5 mmol/L, and urine potassium 10 mmol/L.
You need to evaluate kidney function in a 55-year-old obese man with type 2 diabetes; you ask him to collect his urine over a 24-hour period. He collects 4,320 mL of urine. The clinical laboratory returns the following results from analysis of his urine and plasma samples: Plasma creatinine = 3.0 mg/100 mL Urine creatinine = 40 mg/100 mL Plasma potassium = 5.0 mmol/L Urine potassium = 20 mmol/L What is the net renal tubular secretion rate of potassium in the patient described in question? Group of answer choices .280 mmol/min .140 mmol/min .060 mmol/min .030 mmol/min

Propose one potential mechanism by which asthma might impair kidney function, and discuss how this dysfunction may impair thebody’s ability to respond to respiratory alkalosis
Figure 6 shows measurements of body weight and urinary electrolyte excretion rates in a female before and after taking aldosterone supplements for 3 days. Electrolytes intake rates remained constant throughout. Based on the observed changes in electrolyte excretion and the roles of aldosterone, what could be the reason of the increased body weight during aldosterone treatment?

The laboratory received a 24-hour urine collection from a 26-year old male (body surface area = 2.34m2), and the total urine collection volume measured 800 mL in 24 hours. After creatinine determinations were performed by the alkaline picrate method, interpret the result. Plasma creatinine: 1.2 mg/dL Urine creatinine: 150 mg/dL a. The creatinine clearance of the patient is above reference range. b. The creatinine clearance of the patient is below reference range. c. The creatinine clearance of the patient is within reference range. d. The creatinine clearance of the patient is borderline high.
