EXAM 3-Chapter 31- Nursing AssessmentCardiovascular System-Lewis- Medical-Surgical Nursing- Assessment and Management of Clinical Problems, 6th Edition Test Bank 1. While monitoring a patient's cardiac activity, the nurse recognizes that a normal physiologic mechanism responsible for an increase in heart rate and force of cardiac contractions is stimulation of 1. the vagus nerve. 2. baroreceptors in the aortic arch and carotid sinus. 3. alpha-adrenergic receptors in the vascular system. 4. chemoreceptors in the aortic arch and carotid body. - >>Answer: 4 1. A patient is receiving a drug that decreases peripheral arterial resistance. The nurse anticipates that the effect of this drug on the patient's cardiac function will result in 1. an increase in preload. 2. a decrease in afterload. 3. a decrease in contractibility. 4. a decrease in stroke volume. - >>Answer: 2 1. A patient has a blood pressure of 142/84 mm Hg. The nurse calculates the patient's mean arterial pressure (MAP) as 1. 103 mm Hg. 2. 113 mm Hg. 3. 123 mm Hg. 4. 131 mm Hg. - >>Answer: 1 1. A 70-year-old patient undergoes an exercise treadmill test. The nurse anticipates that as a result of age-related changes in cardiac function, the patient will experience 1. evidence of decreased PR, QRS, and QT intervals. 2. less increase in the heart rate than in a younger patient. 3. a narrowed pulse pressure resulting from an increased diastolic pressure. 4. faster recovery to usual heart rate after exercise than in a younger patient. - >>Answer: 2 1. During physical examination of a 56-year-old man, the nurse palpates the PMI in the sixth intercostal space lateral to the midclavicular line. The most appropriate interpretation of this finding by the nurse is that 1. the PMI is in the normal location. 2. the patient may have left ventricular hypertrophy. 3. the patient has age-related downward displacement of the heart. 4. the patient should be observed for signs of left atrial enlargement. - >>Answer: 2 1. To auscultate for extra heart sounds in the mitral area, the nurse listens with the 1. bell of the stethoscope with the patient in the left lateral position. Continues...
