During a discharge teaching session, the patient voices concern about why her risk of heart disease is elevated simply because she has a history of diabetes mellitus. Based on the nurse’s knowledge, a good explanation is that:
A) Elevated insulin levels associated with diabetes cause vasoconstriction
B) Elevated blood glucose levels promote arterial damage and contribute to arterial damage
C) Diabetics are often obese and thus at higher risk
D) There must be some misunderstanding, since risk for heart disease is not higher for the patient who has diabetes.
B) Elevated blood glucose levels promote arterial damage and contribute to arterial damage
Trace the impulse pattern of the cardiac conduction system.

Which of the following is appropriate patient teaching for self-administration of nitrate medications? (select all that apply)
A) Place nitroglycerin tablets under the tongue at the onset of anginal pain; if pain is unreleived, take a 2nd after 5 minutes and a 3rd after another 5 minutes.
B) Refridgerate medications until use.
C) A burning sensation on the tongue indicates an allergic reaction and requires immediate attention.
D) Place nitroglycerin patches on skin in the morning and remove at bedtime. This prevents development of tolerance and maintains effectiveness.

Which of the following cardiac markers is specific to the heart, not influenced by skeletal muscle trauma or renal failure, and rises 3 hours following a myocardial infarction? A) CK-MB B) Troponin I C) Homocysteine D) Myoglobin
B) Troponin I
You are caring for an older woman with cardiac disease. Based on your knowledge, you realize that the older cardiac patient is different from the younger cardiac patient because:
A) The cardiac output tends to be increased in the older adult.
B) The younger adult tends to have a more extensive network of collateral circulation than the older adult.
C) Dyspnea is a typical symptom of a myocardial infarction in the younger adult, whereas angina is the more common symptom in the older adult.
D) Even with lower doses of medications, the older adult should be observed for signs and symptoms of toxicity.
D) Even with lower doses of medications, the older adult should be observed for signs and symptoms of toxicity.
In evaluating your patient’s risk factors for cardiovascular disease, you identify that the following is a modifiable risk factor that he possesses:
A) Family history of cardiovascular disease
B) Age
C) Active lifestyle
D) Hyperlipidemia
D) Hyperlipidemia
Of the following, which is the most serious type of dysrhythmia? A) Atrial fibrillation B) Ventricular fibrillation C) Supraventricular tachycardia D) Sinus bradycardia
B) Ventricular fibrillation
Which of the following is/are true statements regarding angina pectoris? Select all that apply.
A) Angina indicates a lack of oxygen and blood supply to the heart.
B) Angina only occurs at rest.
C) Angina may resemble heartburn or indigestion.
D) Angina is usually relieved by nitroglycerin.
E) Angina may appear as jaw pain.
A) Angina indicates a lack of oxygen and blood supply to the heart
C) Angina may resemble heartburn or indigestion.
D) Angina is usually relieved by nitroglycerin.
E) Angina may appear as jaw pain.
Your patient was admitted yesterday for a myocardial infarction. Select the following statement that is true regarding treatment for a patient with myocardial infarction.
A) Thrombolytic agents, such as aspirin, are used to minimize infarct size and maximize heart function.
B) Thrombolytic agents must be initiated within 24 hours of the onset of symptoms in order to be effective.
C) Morphine sulfate is contraindicated in a patient with a myocardial infarction due to its effects on the central nervous system.
D) The patient with an acute myocardial infarction will be on bedrest with commode privileges for 24 to 48 hours.
D) The patient with an acute myocardial infarction will be on bedrest with commode privileges for 24 to 48 hours.
The nurse is interviewing a male client with hypertension. Which additional medical diagnosis in the client's history presents the greatest risk for development of a cerebral vascular accident (CVA)? A. Diabetes mellitus B. Hypothyroidism C. Parkinson disease D. Recurring pneumonia
A. Diabetes mellitus
Poorly controlled glucose levels stimulate fat mobilization, which predisposes to atherosclerosis.
A 55 year old male client is admitted to the coronary care unit with chest pain. Within the first 24 hours, which diagnostic laboratory value should the nurse suspect to be indicative of an acute myocardial infarction? A. Elevated serum amylase level B. Elevated CM-MB level C. Prolonged prothrombin time (PT) D. Elevated serum BUN and creatinine
B. Elevated CM-MB level
Tissue damage in the myocardium causes the release of cardiac enzymes into the blood system. An elevated CM-MB is a recognized indicator of MI.
**Other tests to diagnose MI: BNP and troponins I and T
