Answer to Question 1

D
An adult's blood pressure tends to rise with advancing age. The optimal blood pressure for a healthy, middle-aged adult is less than 120/80 . Values of 120 to 139/80 to 89 mm Hg are considered prehypertension. Blood pressure greater than 140/90 is defined as hypertension. Blood pressure of 98/50 is normal for a child, whereas 115/70 can be normal for an infant.

Answer to Question 2

A
In a systematic review or meta-analysis, an independent researcher reviews all of the RCTs conducted on the same clinical question and reports whether the evidence is conclusive, or if further study is needed. A single RCT is not as conclusive as a review of several RCTs on the same question. Control trials without randomization may involve bias in how the study is conducted. Case control studies also have room for bias.
