A recent episode of chest pain while doing yard work prompted a 70-year-old man to seek care and he has been subsequently diagnosed with chronic stable angina. The nurse should recognize what guiding principle in the treatment of this patient's angina? a) The patient will likely have a trial of antiplatelet drugs before being prescribed nitrates. b) The patient would benefit from a weekly intravenous dose of a beta blocker. c) The patient's angina may necessitate the use of a calcium channel blocker. d) The patient indicates a need for daily low-molecular weight heparin therapy

Answer: The patient's angina may necessitate the use of a calcium channel blocker. Rationale: Calcium channel blockers are used in chronic stable angina when the patient cannot tolerate beta blockers, or if the symptoms are not adequately controlled while on this therapy. Regularly-scheduled beta blockers are not administered intravenously. Low molecular weight heparin is not typically used in the treatment of stable angina and antiplatelet medications do not need to precede the use of nitrates.
