Urinalysis Questions 1. A patient has urine with the following characteristics: Color—very pale yellow pH—low (about 4.1) Specific gravity—high (greater than 1.030) Ketones—high concentration Glucose concentration—very high concentration a. What condition might this patient have? b. Explain your reasoning: c. Considering the fact that the patient's urine (and blood) contains excess glucose, why was the patient suffering from excessive thirst and urination? d. Considering the fact that neither the liver nor body cells of this patient were taking up glucose, why was the patient suffering from tiredness and losing weight?

The following lab results were reported for a 15-year-old male. His mother told the physician that he had lost weight recently, even though his appetite and thirst had increased dramatically. She also said she believed her son to be extremely fatigued because he would get up to use the bathroom in the middle of the night. Plasma: - Glucose: 165 (80-150 mg/dL) (fasting) - Sodium: 139 (135-145 mEq/L) - Potassium: 4.2 (3.0-5.0 mEq/L) - Chloride: 102 (98-103 mEq/L) - CO2: 29 (22-27 mmol/L) Urine: - Specific Gravity: 1.040 - Glucose: 4+ - Ketones: Moderate - Proteins: 2+ - pH: 6.5 What likely condition do the results indicate (be specific by type)? Which of the above parameters indicates the condition and why? What other blood tests might the physician order and why?
