NURSING 6005 CHAPTER 43: REVIEW OF HEMODYNAMICS Test Bank MULTIPLE CHOICE 1. A patient is taking a beta1-adrenergic drug to improve the stroke volume of the heart. The nurse caring for this pa... tient knows that this drug acts by increasing: a. cardiac afterload. b. cardiac preload. c. myocardial contractility. d. venous return. 2. A nurse is caring for a patient who is receiving a drug that causes constriction of arterioles. The nurse expects to observe which effect from this drug? a. Decreased stroke volume b. Increased stroke volume c. Decreased myocardial contractility d. Increased myocardial contractility 3. A patient with a history of hypertension is admitted for a procedure. If the patient’s arterial pressure decreases, which clinical manifestation would the nurse expect to see? a. Decreased heart rate b. Increased heart rate c. Decreased blood pressure d. Syncope 4. A nurse is teaching a nursing student how blood can return to the heart when pressure in the venous capillary beds is very low. Which statement by the student indicates a need for further teaching? a. “Constriction of small muscles in the venous wall increases venous pressure.” b. “Negative pressure in the left atrium draws blood toward the heart.” c. “Skeletal muscles relax to allow the free flow of blood.” d. “Venous valves help prevent the backflow of blood.” 5. A nurse is assessing a patient with heart failure. The patient complains of shortness of breath, and the nurse auscultates cracklesin both lungs.
