A patient has recently been prescribed nitroglycerin for treatment of angina. He calls the nurse and tells her that he is having frequent headaches. Which of the following responses to the patient is correct?
  1. "Stop taking the nitroglycerin and see if the headaches improve."
  2. "Immediately report to the emergency department as nitroglycerin may cause brain hemorrhage."
  3. "Headaches are a common side effect of nitroglycerine because it causes vasodilation."
  4. "The headache has nothing to do with the nitroglycerin, see your doctor for further investigation."
Explanation
Answer- C - Nitroglycerin is a potent vasodilator and often produces unwanted side effects related to vasodilation such as headache, dizziness, and hypotension. Patients should be counselled, and the dose adjusted to minimize the side effects. Despite these side effects, nitroglycerine is effective at reducing myocardial oxygen consumption and increasing blood flow. The patient should not be instructed to stop the medication. Nitroglycerine does not cause brain hemorrhage.
