- The normal calculated anatomic shunt is about A. 0.5-1 percent B. 2-5 percent C. 6-9 percent D. 10-12 percentarrow_forwardWhen the systemic blood pressure increases, the aortic and carotid sinus baroreceptors initiate reflexes that cause a/an 1. Increased heart rate 2. Decreased ventilatory rate 3. Increased ventilatory rate 4. Decreased heart rate A. 1 only B. 2 only C. 3 only D. 2 and 4 onlyarrow_forwardWhich of following is true 1. A greater pressure in the right ventrical than the aort causes the pulmonary valve to open 2. The oxygen content of arteries in the pulmonary circulation is high 3. none of the choice are true 4. If the tricuspid valves did not close fully, you could expect blood to get congested(backed up) in the venous systemarrow_forward
- Heart failure occurs when a. the cardiac output is 15 liters per minute when you are watching television b. the cardiac output is 5 liters per minute when you are running as fast as you can on the treadmill. c. the cardiac outout does not change based on the energy expenditure d. all of the abovearrow_forward7. The P-Wave in the electrocardiogram... A)Gives information about the oxygenation content of the blood B)Happens when the semilunar valves are closed C)Can give information about how much blood is pumped out D)Represents atrial contraction E)Two of these options are correctarrow_forwardWhile taking an adult patient’s pulse, a nurse finds the rate tobe 140 beats/min. What should the nurse do next?a. Check the pulse again in 2 hours.b. Check the blood pressure.c. Record the information.d. Report the rate to the primary care provider.arrow_forward
- 9. A patient's cardiac output is measured as 5849.58 mL/min using the Fick's method. The spirometer measures an oxygen content in 600 mL of arterial blood. The spirometer measures 23.5 mL of oxygen for every 1000 mL of venous blood. If the oxygen uptake is 350 mL/min, find the oxygen content in 600 ml of arterial blood in ml.arrow_forward8. After passing through the aortic semilunar valve, a red blood cell accidentally flows backwards through a small leak in the valve. This red blood cell landed in... A)the pulmonary arteries B)the aorta C)the left ventricle D)the right ventricle E)the right atrium F)the pulmonary veins G)the left atriumarrow_forward7). Answer it.! A patient hospitalised with aortic stenosis has activity intolerance related to insufficient oxygen due to decreased cardiac output. An appropriate nursing intervention for this patient is to: Select one: a. Progressively increase activity to increase cardiac tolerance b. Maintain on bed rest to reduce tissue oxygen demands c. Monitor electrocardiography to assess cardiac output d. Use a Semi-Fowler position to decrease venous return and increase respiratory excursion.?arrow_forward
- The preoperative characteristic of patients likely to experience postoperative ischemia after noncardiac surgery include() A) Angina B) More than three premature ventricular contractions(PVCs) per minute C) Dyspnea on exertion D) Age greater than 60 years E) Feverarrow_forward7). Answer it.! AsapA patient hospitalised with aortic stenosis has activity intolerance related to insufficient oxygen due to decreased cardiac output. An appropriate nursing intervention for this patient is to:Select one:a.Progressively increase activity to increase cardiac toleranceb.Maintain on bed rest to reduce tissue oxygen demandsc.Monitor electrocardiography to assess cardiac outputd.Use a Semi-Fowler position to decrease venous return and increase respiratory excursion.?arrow_forwardA 1.5 L IV of D5W fluid is administered to a patient at 10AM at a flow rate of 75 mL/hr. How long will the IV bag last? Group of answer choices a. 20 hours b. 24 hours c. 8 hours d. 12 hoursarrow_forward
