41-year-old obese male patient is diagnosed with congestive heart failure (CHF). He is told to begin a moderate exercise routine with a healthy diet and is prescribed several medications — including a diuretic.
Based on your knowledge of the kidney and the disease of CHF, what factors would be important in selecting a specific diuretic? How would you explain to this patient how it works?
If this patient developed a disease that caused the renal blood flow to be diminished, how might this impact the medication he is taking for his congestive heart failure? As his health care provider, how would you change his treatment in this situation?
