Angina, MI, Aneurysms Questions (NCLEX) Answered 2022 The nurse teaches the client that the major difference between angina and pain associated with myocardial infarction (MI) is that: A) Angina is relieved with nitroglycerin and rest. B) Angina can be fatal. C) MI pain always radiates to the left arm or jaw. D) MI pain cannot be treated. - ✔✔A) Angina is relieved with nitroglycerin and rest. The teaching plan for a client being started on long-acting nitroglycerin includes the action of this drug. The nurse teaches that this drug relieves chest pain by which action? A) Dilating just the coronary arteries B) Decreasing the blood pressure C) Increasing contractility of the heart D) Dilating arteries and veins - ✔✔D) Dilating arteries and veins The nurse cautions the client receiving isosorbide dinitrate for treatment of angina that long-term use can lead to the development of: A) Tolerance. B) Tachycardia. C) Hypotension. D) Urinary retention. - ✔✔A) Tolerance. The nurse prepares discharge teaching for a client receiving isosorbide dinitrate for treatment of angina. What information must the nurse include?A) Limit exercise to 30 minutes twice per week. B) Avoid alcohol consumption. C) Monitor intake and output. D) Report skin flushing to the physician. - ✔✔B) Avoid alcohol consumption. The nurse recognizes that the mechanism for action of beta-adrenergic blockers in the treatment of angina is: A) Positive chronotropic effect. B) Negative inotropic effect. C) Positive inotropic effect. D) Antidysrhythmia. - ✔✔B) Negative inotropic effect. Rationale: Beta blockers decrease the workload of the heart by slowing heart rate (negative chronotropic effect) and reducing contractility (negative inotropic effect). What does the nurse include in the teaching plan for a client receiving a beta blocker for treatment of angina? A) Discontinue drug if heart rate <60. B) Do not discontinue drug abruptly. C) Exercise heart rate should be 110-120. D) Monitor for hyperglycemia. - ✔✔B) Do not discontinue drug abruptly. Rationale: Beta blocker treatment should never be abruptly discontinued. With abrupt cessation, a rebound excitation occurs, and adrenergic receptors are stimulated. This can exacerbate angina, increase heart rate, and cause myocardial infarction. Clients often tolerate heart rates as low as 50. The beta blocker might blunt the compensatory increase in heart rate with exercise. Hypoglycemia can occur.The nurse recognizes that calcium channel blockers prescribed for treatment of angina exert their effect by: A) Increasing preload. B) Decreasing afterload. C) Positive chronotropic effect. D) Positive inotropic effect. - ✔✔B) Decreasing afterload.
