MULTIPLE CHOICE

1. A client is learning about cholesterol. The nurse explains that the “good cholesterol” transports plasma cholesterol away from plaques and to the liver for metabolism. This type of cholesterol is called:

ANS:  1

High-density lipoprotein transports plasma cholesterol away from atherosclerotic plaques and to the liver for metabolism and excretion. Low-density lipoproteins, or “bad cholesterol,” are the main component of the atherosclerotic plaque. Very-low-density lipoproteins are considered more atherogenic and are more common in men and people with diabetes.

2. A client has a blood pressure of 124/78 mmHg and a triglyceride level of 160 mg/dL. Based on these results, the nurse knows that the client has:

ANS:  3

Prehypertensive blood pressure ranges systolically from 120 to 139 mmHg or diastolically from 80 to 90 mmHg. Stage I hypertension is systolic blood pressure (SBP) of 140 to 159 mmHg or a diastolic blood pressure (DBP) of 90 to 99 mmHg. Optimal triglyceride levels are less than 150 mg/dL. Triglyceride levels from 150 to 199 mg/dL are considered borderline high. Triglyceride levels at 200 to 499 mg/dL are considered high.

3. The nurse measures a client’s blood pressure to be 158/92 mmHg. The nurse recognizes that this blood pressure is classified as:

ANS:  3

Normal blood pressure is SBP less than 120 mmHg and DBP less than 80 mmHg. A prehypertensive state is SBP of 120 to 139 mmHg or DBP of 80 to 90 mmHg. Stage I hypertension is SBP of 140 to 159 mmHg or DBP of 90 to 99 mmHg. Stage II hypertension is a SBP of 160 mmHg or higher or a DBP of 100 mmHg or higher.

4. A client is complaining of chest pain that occurs during exercise. This pain is relieved when the client rests. The nurse realizes that this client is experiencing which type of angina?

ANS:  3

Stable angina is precipitated by factors that increase oxygen demand or reduce oxygen supply. Chest pain occurs predictably with the same onset, duration, and intensity and is relieved when the precipitating factor is removed or with nitroglycerin. Unstable angina is typified by an increase in frequency, duration, and intensity of symptoms at lower levels of activity and even at rest. Prinzmetal’s variant angina is a coronary artery spasm. Silent angina can occur with no pain at all and is common in diabetic patients.

5. A client diagnosed with stable angina is undergoing a 12-lead electrocardiogram. Which of the following results is not expected?

ANS:  2

During an episode of angina, T-wave flattening or inversions and ST segment depression may be seen on the electrocardiogram due to subendocardial ischemia. ST segment elevation is seen with impending or acute myocardial infarction.
