Answer to Question 1
Correct Answer: 1
The blood pressure should be taken in the arm opposite the surgical site. Blood pressures should not be taken on the same side as a mastectomy. It should also not be taken on an arm with a shunt, trauma, or disease. If this is not possible, then a thigh pressure should be obtained. The nurse should be sure to provide the PCA with instructions to use the arm opposite the surgical site for blood pressure readings. The left arm should not be used for blood pressure readings, intravenous fluids, or other invasive procedures. It is not possible to take the blood pressure using both arms, since the left arm should never be used again for blood pressure readings. If bilateral readings become necessary, the thighs should be used so that a comparison can be made.
Answer to Question 2
Correct Answer: 3, 4
Arteriosclerosis results in hardened and rigid arteries, which are less compliant. Elasticity of blood vessels decreases with age and also leads to increased blood pressure. Arteriosclerosis requires greater ventricular force and leads to increased blood pressure. Arteriosclerosis decreases the elasticity of the arteries. Arteriosclerosis has a direct effect on blood pressure; decreased elasticity and compliance is directly related to the increase in blood pressure.
