The nurse is caring for a patient who is 3 days post myocardial infarction and the patient states, 'I just had a little chest pain. As soon as I get out of here, I'm going for my vacation as planned' Which of the following responses should the nurse make?
- A. Where are you planning to go for your vacation?
- B. What do you think caused your chest pain episode?
- C. Sometimes plans need to change after a heart attack.
- D. Recovery from a heart attack takes at least a few weeks.
Correct Answer: B
Rationale: When the patient is experiencing denial, the nurse should assist the patient in testing reality until the patient has progressed beyond this step of the emotional adjustment to MI. Asking the patient about vacation plans reinforces the patient's plan, which is not appropriate in the immediate post-MI period. Reminding the patient in denial about the MI is likely to make the patient angry and lead to distrust of the nursing staff.

The nurse is providing teaching to a patient about use of sublingual nitroglycerin. Which of the following patient statements indicates that the teaching has been effective?
- A. I will put the nitroglycerin tablet under my tongue if I get chest pain.
- B. I like fresh salmon and I will plan to eat it more often.
- C. I will miss being able to eat peanut butter sandwiches.
- D. I can have a cup of coffee with breakfast if I want one.
Correct Answer: A
Rationale: Sublingual nitroglycerin is taken by placing the tablet under the tongue to relieve chest pain. The other statements relate to dietary preferences and do not indicate understanding of nitroglycerin use.
Following an acute myocardial infarction, a patient ambulates in the hospital hallway. When the nurse is evaluating the patient's response, which of the following assessment data would indicate that the exercise level should be decreased?
- A. BP changes from 118/60 to 126/68 mm Hg.
- B. Oxygen saturation drops from 100% to 98%.
- C. Heart rate increases from 66 to 90 beats/minute
- D. Respiratory rate goes from 14 to 22 breaths/minute.
Correct Answer: C
Rationale: A change in heart rate of more than 20 beats or more indicates that the patient should stop and rest. The increases in BP and respiratory rate, and the slight decrease in oxygen saturation, are normal responses to exercise.
The nurse is providing teaching to a patient with persistent stable angina about how to use the prescribed short-acting and long-acting nitrates. Which of the following patient statements indicates that the teaching has been effective?
- A. I will put on the nitroglycerin patch as soon as I develop any chest pain.
- B. I will check the pulse rate in my wrist just before I take any nitroglycerin.
- C. I will be sure to remove the nitroglycerin patch before using any sublingual nitroglycerin.
- D. I will stop what I am doing and sit down before I put the nitroglycerin under my tongue.
Correct Answer: D
Rationale: The patient should sit down before taking the nitroglycerin to decrease cardiac workload and prevent orthostatic hypotension. Transdermal nitrates are used prophylactically rather than to treat acute pain and can be used concurrently with sublingual nitroglycerin. Although the nurse should check blood pressure before giving nitroglycerin, patients do not need to check the pulse rate before taking nitrates.
Which of the following information about a patient who has been receiving fibrinolytic therapy for an acute myocardial infarction is most important for the nurse to communicate to the health care provider?
- A. No change in the patient's chest pain
- B. A large bruise at the patient's IV insertion site
- C. A decrease in ST segment elevation on the electrocardiogram (ECG)
- D. An increase in cardiac enzyme levels since admission
Correct Answer: A
Rationale: Continued chest pain suggests that the fibrinolytic therapy is not effective and that other interventions such as percutaneous coronary intervention (PCI) may be needed. Bruising is a possible adverse effect of fibrinolytic therapy, but it is not an indication that therapy should be discontinued. The decrease of the ST segment elevation indicates that fibrinolysis is occurring and perfusion is returning to the injured myocardium. An increase in cardiac enzyme levels is expected with reperfusion and is related to the washout of enzymes into the circulation as the blocked vessel is opened.
The nurse is caring for a patient with a non-ST-segment-elevation myocardial infarction (NSTEMI) who is receiving heparin. Which of the following information explains the purpose of the heparin?
- A. Platelet aggregation is enhanced by IV heparin infusion.
- B. Heparin will dissolve the clot that is blocking blood flow to the heart.
- C. Coronary artery plaque size and adherence are decreased with heparin.
- D. Heparin will prevent the development of new clots in the coronary arteries.
Correct Answer: D
Rationale: Heparin helps prevent the conversion of fibrinogen to fibrin and decreases coronary artery thrombosis. It does not change coronary artery plaque, dissolve already formed clots, or enhance platelet aggregation.
