Answer to Question 1

ANS: C
The hematocrit, or the percentage of red blood cells in the blood, determines blood viscosity. Blood cultures determine the causative agent of an infection. Abnormal potassium levels can cause dysrhythmias. Arterial blood gases determine acid-base balance or the pH levels of the blood.

Answer to Question 2

ANS: B
The difference between the systolic pressure and the diastolic pressure is the pulse pressure. For a blood pressure of 140/60, the pulse pressure is 80 (140  60 = 80). 140 is the systolic pressure. 60 is the diastolic pressure. 200 is the systolic (140) added to the diastolic (60), but this has no clinical significance.
