To assist the patient with coronary artery disease (CAD) in making appropriate dietary changes, which of the following nursing interventions will be most effective?
- A. Instruct the patient that a diet containing no saturated fat and minimal sodium will be necessary.
- B. Emphasize the increased risk for cardiac problems unless the patient makes the dietary changes.
- C. Assist the patient to modify favourite high-fat recipes by using polyunsaturated oils when possible.
- D. Provide the patient with a list of low-sodium, low-cholesterol foods that should be included in the diet.
Correct Answer: C
Rationale: Lifestyle changes are more likely to be successful when consideration is given to the patient's values and preferences. The highest percentage of calories from fat should come from polyunsaturated fats. Although low-sodium and low-cholesterol foods are appropriate, providing the patient with a list alone is not likely to be successful in making dietary changes. Removing saturated fat from the diet completely is not a realistic expectation. Telling the patient about the increased risk without assisting further with strategies for dietary change is unlikely to be successful.

The nurse is administering IV nitroglycerin to a patient with a myocardial infarction (MI). Which of the following actions should the nurse take to evaluate the effectiveness of the medication?
- A. Check blood pressure.
- B. Monitor apical pulse rate.
- C. Monitor for dysrhythmias.
- D. Ask about chest discomfort.
Correct Answer: D
Rationale: The goal of IV nitroglycerin administration in MI is relief of chest pain by improving the balance between myocardial oxygen supply and demand. The nurse also will monitor heart rate and BP and observe for dysrhythmias, but these parameters will not indicate whether the medication is effective.
Which of the following information collected by the nurse who is admitting a patient with chest pain suggests that the pain is caused by an acute myocardial infarction?
- A. The pain increases with deep breathing.
- B. The pain has persisted longer than 30 minutes.
- C. The pain worsens when the patient raises the arms.
- D. The pain is relieved after the patient takes nitroglycerin.
Correct Answer: B
Rationale: Chest pain that lasts for 20 minutes or more is characteristic of an acute myocardial infarction. Changes in pain that occur with raising the arms or with deep breathing are more typical of pericarditis or musculoskeletal pain. Stable angina is usually relieved when the patient takes nitroglycerin.
A patient with ST segment elevation in several electrocardiogram (ECG) leads is admitted to the emergency department (ED) and diagnosed as having an ST-segment-elevation myocardial infarction (STEMI). Which of the following questions should the nurse ask to determine whether the patient is a candidate for fibrinolytic therapy?
- A. Do you take Aspirin on a daily basis?
- B. What time did your chest pain begin?
- C. Is there any family history of heart disease?
- D. Can you describe the quality of your chest pain.
Correct Answer: B
Rationale: Fibrinolytic therapy should be started within 6 hours of the onset of the myocardial infarction (MI), so the time at which the chest pain started is a major determinant of the appropriateness of this treatment. The other information also will be needed, but it will not be a factor in the decision about fibrinolytic therapy.
The nurse is assessing a patient who has chest pain is to the emergency department and all the following diagnostic tests are prescribed. Which of the following tests should the nurse arrange to be completed first?
- A. Electrocardiogram (ECG)
- B. Computed tomography (CT) scan
- C. Chest x-ray
- D. Troponin level
Correct Answer: A
Rationale: The priority for the patient is to determine whether an acute myocardial infarction (AMI) is occurring so that reperfusion therapy can begin as quickly as possible. ECG changes occur very rapidly after coronary artery occlusion. Troponin levels will increase after about 3 hours. Data from the CT scan and chest x-ray may impact the patient's care but are not helpful in determining whether the patient is experiencing a myocardial infarction (MI).
The nurse is caring for a patient with hyperlipidemia who has a new prescription for colestipol. Which of the following nursing actions is best when giving the medication?
- A. Administer the medication at the patient's bedtime.
- B. Have the patient take this medication with an Aspirin.
- C. Encourage the patient to take the colestipol with a sip of water.
- D. Give the patient's other medications 2 hours after the colestipol.
Correct Answer: D
Rationale: The bile acid sequestrants interfere with the absorption of other drugs, and giving other medications at the same time should be avoided. Taking an aspirin concurrently with the colestipol may increase the incidence of gastrointestinal adverse effects such as heartburn. An increased fluid intake is encouraged for patients taking the bile acid sequestrants to reduce the risk for constipation. For maximum effect, colestipol should be administered with meals.
