The nurse is instructing a patient on nitroglycerin tablets prescribed to treat angina. Which statement(s) should be included in the nurse's instructions?
Select all that apply.
1. "Take a second dose if the angina is not relieved within five minutes."
2. "The drug should remain in this brown bottle since it is sensitive to light."
3. "Store this medication in your bathroom medicine cabinet so it is readily available to you."
4. "Eating or drinking will not interfere when taking the medication."
5. "Call your doctor immediately if you develop a headache when taking this drug."
Correct Answer: 1, 2
A second dose of nitrates is recommended within five minutes if the first dose does not relieve the angina. Sublingual nitrates should not be removed from their original amber bottle since it protects the medication from light. They should be stored in a dry location and not placed in the bathroom medicine cabinet since moisture affects nitrates. This medication is taken sublingually; therefore, eating and drinking will interfere with absorption. A transient headache may occur when taking this medication and will diminish over time.
