Answer to Question 1

B

Feedback
A Stage 1 does not account for the greatest proportion of total sleep time in adults.
B Stage 2 accounts for the greatest proportion of total sleep time in adults, as it comprises 45 to 55 of total sleep.
C Stage 3 does not account for the greatest proportion of total sleep time in adults.
D Stage 4 does not account for the greatest proportion of total sleep time in adults.

Answer to Question 2

C
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.
