A 30-year-old man presents to your clinic complaining of excessive thirst and frequent urination for the past few months. Urine testing reveals a low urine osmolarity, which fails to increase after subjecting the patient to a water deprivation test and injection of desmopressin. Further into the encounter, the patient reveals that he has been on a mood stabilizer for bipolar disorder for several years. Which of the following is the most likely cause of his polyuria?

A 48-year-old female presents to the clinic due to 3 weeks of increased thirst and increased urination. She has a history of obesity, hypertension and depression and has smoked a pack of cigarettes daily for the past 28 years. Her current medications include lisinopril and sertraline. T 98.5°F, BP 148/90 mmHg, HR 84/min, and RR 15/min. Her physical exam is normal, and her laboratory values are as follows:   Serum: Na+: 140 mEq/L K+: 4.4 mEq/L HCO3-: 21 mEq/L BUN: 38 mg/dL Creatinine: 1.1 mg/dL Glucose: 215 mg/dL Which of the following is the most appropriate screening test for nephropathy in this patient?

 A 22-year-old female presents with urinary frequency. Her BMI is 41. A urinalysis is positive for glucose. Her random blood sugar is 257 mg/dL, hemoglobin A1c is 8.5%, and C-peptide is 1.5 ng/mL. She is diagnosed with type 2 diabetes; diet and exercise are recommended. What is the drug of choice for managing her diabetes?

The mean free path of an oxygen molecule is [l] m, when the gas is at a pressure of [p] Pa and a temperature of [t] K. The molar mass of oxygen is 32.0 g/mol. Assuming that the molecules are moving at their root-mean-square speeds, what is the average time interval between collisions of an oxygen molecule in nanoseconds? 1 ns = 10-9 s Boltzmann constant = 1.38 × 10-23 J/K Avogadro’s number = 6.02 × 1023 molecules/mole R = 8.314 J/mol · K = 0.0821 L · atm/mol · K.  Enter only a numerical value (3 sig. fig) without units.
