Med Surg Hesi |Real Exam| Questions with Complete Solution and Rationale Graded A+ 2023/2024
Multiple Choice
1 of 60
The nurse is concerned about a patient's stroke volume. What determining factors should the nurse consider when determining stroke volume?
1 Preload, afterload, and contractility
2 Cardiac output, heart rate, and body surface area
3 Afterload, cardiac output, and mean arterial pressure
4 Cardiac index, mean arterial pressure, and blood pressure {{Correct Ans- 1
Preload, afterload, and contractility determine stroke volume (SV). Cardiac output and heart rate are used to determine stroke volume; however, body surface area is used to determine cardiac index. Mean arterial pressure is used to determine afterload, not stroke volume. Cardiac index is a more precise measurement of the efficiency of the heart's pumping action; it is not used to determine stroke volume.
2 of 60
The nurse is caring for a patient receiving intraaortic balloon pump (IABP) therapy. On which part of the electrocardiogram should the nurse expect the balloon to be inflated?
1 P wave
2 Q wave
3 R wave
4 T wave {{Correct Ans- 4
The electrocardiogram (ECG) is the trigger for the pump to start inflation on the T wave. Deflation occurs on the upstroke of the R wave (of the QRS) complex. The P and Q waves are not triggers for the pump to either inflate or deflate.
3 of 60
The nurse is attempting to determine a patient's left ventricular afterload. Which hemodynamic value should the nurse use?
1 Central venous pressure
2 Pulmonary arterial pressure
3 Systemic vascular resistance
4 Peripheral vascular resistance {{Correct Ans- 3
Systemic vascular resistance is an index of left ventricular afterload. Central venous pressure is an index of preload. Pulmonary arterial pressure and peripheral vascular resistance are indices of right ventricular afterload.
4 of 60
A patient with severe left ventricular failure is considering artificial heart transplantation. What should the nurse inform the patient is a long-term treatment associated with this device?
1 Beta-blockers
2 Anticoagulation
3 Antibiotic therapy
4 Immunosuppressive agents {{Correct Ans- 2
Patients require lifelong anticoagulation with an artificial heart. Beta-blockers are not indicated for this device. Antibiotic therapy is not indicated for this device. Patients do not require immunosuppression with this device.
