Textbook Question
Chapter 18, Problem 6CCS
54-Year-Old Female with a Defective Heart Valve
Dr. El-Sheikh is a 54-year-old Egyptian female who complains of weakness, fatigue, shortness of breath, chest pain, and dizziness. Her heart rate is 96 beats/min, and her blood pressure is 148/54 mm Hg. You notice that she nods her head with every heartbeat, and her radial pulse is very strong and abrupt. Her heart sounds are abnormal, with a long diastolic murmur at the right sternal margin in the second intercostal space.
Her doctor orders an echocardiogram, which shows that Dr. El-Sheikh has severe aortic regurgitation (backflow of blood through an incompetent valve) and an enlarged left ventricle.
6. NCLEX-STYLE Although Dr. El-Sheikh has a high systolic blood pressure, her heart rate is also high. This is most likely due to:
a. The Bainbridge reflex, caused by increased atrial filling
b. Parasympathetic activation
c. Excessive vagus nerve firing
d. Sympathetic stimulation

E. Bar Graph
Use the same technique to upload the completed image.
We will use a different type of graph to derive additional information from the
CO2 data (Fig A1.6.2)
1. Calculate the average rate of increase in COz concentration per year for the time intervals 1959-1969, 1969-
1979, etc. and write the results in the spaces provided. The value for 1959-1969 is provided for you as an
example.
2. Plot the results as a bar graph. The
1959-1969 is plotted for you.
3. Choose the graph that looks the most like yours

The relative motion between the plates is indicated by the half arrows along the transform plate boundary (i.e., the Pacific Plate is moving to the northwest relative to the North American Plate). Note the two bodies of Oligocene volcanic rocks (labeled Ov) on the map in the previous page located along either side of the San Andreas Fault. These rocks are about 23.5 million years old and were once one body of rock. They have been separated by displacement along the fault. 21. Based on the offset of these volcanic rocks, what is the average annual rate of relative plate motion in cm/yr?
