Case Study Essay Questions

 

Ernest Hare is a 75-year-old retired railroad engineer. He has a history of myocardial infarction, hypertension, congestive heart failure, and anxiety. His medications include warfarin, simvastatin, Lopressor, lorazepam, and Lasix. In addition to these prescription drugs, Mr. Hare takes garlic tablets and St. John’s wort.

 

  1. As a health professional, what steps should you take to determine if any of the medications and supplements Mr. Hare is taking has the potential for diet-drug or drug-drug interactions?
  2. Do any of the drugs Mr. Hare is taking prevent him from safely consuming grapefruit? If so, which ones and why?
  3. Which medication that Mr. Hare is taking interacts with vitamin K? How does this interaction occur?
  4. How should Mr. Hare be counseled regarding his vitamin K intake?
  5. Could either of the dietary supplements Mr. Hare is taking interact with his prescription medications? If so, which ones and why?

 

  1. Yes. Grapefruit should not be consumed when taking simvastatin. Compounds in grapefruit juice (or whole grapefruit) have been found to inhibit or inactivate enzymes that metabolize a number of different drugs, including simvastatin. As a result of the reduced enzyme action, blood levels of the drugs increase, leading to stronger physiological effects. The effect of the grapefruit juice lasts for a substantial period after the juice is consumed.
  2. Warfarin interacts with vitamin K. The two are structurally similar. Warfarin acts by blocking the enzyme that activates vitamin K, thereby preventing the synthesis of blood-clotting factors. The amount of warfarin prescribed is dependent, in part, on how much vitamin K is in the diet. If vitamin K consumption from foods or supplements changes substantially, it can alter the effect of the drug.
  3. Individuals using warfarin are advised to consume similar amounts of vitamin K daily to keep warfarin activity stable. The dietary sources highest in vitamin K are green leafy vegetables such as spinach, kale, Brussels sprouts, collard greens, and mustard greens. A registered dietitian can provide individualized guidance.
  4. Both St. John’s wort and garlic can interact with the warfarin Mr. Hare is taking. They enhance the activity of warfarin.

Case Study Essay Questions

 

Refinery Worker with History of Kidney Stones: Steve Forbes is a 52-year-old refinery worker who wrecked his motorcycle on the way to work one morning. He was taken to the emergency room with multiple broken bones, and a CT scan was performed to rule out internal injuries. Incidentally, the results of the CT scan showed that Mr. Forbes had two large stones in his right kidney. After Mr. Forbes’s broken bones healed, he underwent surgery to have the kidney stones removed. An analysis of the stones determined that they were calcium oxalate stones. Two years later, Mr. Forbes experienced severe back pain, nausea, and the inability to urinate. He returned to the emergency room for treatment.

 

  1. What is a kidney stone and how does one develop?
  2. What are the possible causes of Mr. Forbes’s calcium oxalate stone?
