· What laboratory parameters would be routinely monitored in the above patient

– Lasix: BUN, creatinine & electrolytes (specifically potassium) loop diuretic therapy – Avandia: monitor LFT’s (increase sensitivity at of insulin at the receptor site) – Metformin: use cautiously with renal insufficiency patients—monitor BUN and creatinine (if levels are too high, not a candidate for biguinides) – Potassium supplements: potassium levels
– Metaprolol: monitor blood glucose can mask signs of hypoglycemia – Prinivil: monitor potassium levels (has a tendency to increase), – Allopurinol: monitor BUN, creatinine

· Why was Zithromax chosen to treat this patient?

– Zithromax was chosen to treat this patient because it doesn’t interact with liver function and it has a broader range of coverage for both gram (+) and gram (-) bacteria that can treat the pneumonia that is possibly causing the fever. This patient is also allergic to penicillin.

· What factor increases this patient’s risk for gout?

– This patient is taking a loop diuretic, Lasix, which significantly increases the risk for gout due to the concentration of uric acid in the blood. – Hypertension
– Diabetes can cause renal insufficiency which can lead to uric acid build up

· Allopurinol is used to prevent recurrent gout in this patient. The standard dose is 300 mg daily. Why is this patient only on 100 mg daily?

– This patient has chronic renal insufficiency and therefor the drug needs to be adjusted, this drug is also used to for maintenance therapy and not for acute attacks
