Inflating the cuff to a pressure 30 mm Hg above the point where the pulse has disappeared, after closing the screw clamp on the bulb, helps ensure that the systolic reading is not underestimated. Assisting the client to a comfortable position helps to foster cooperation. Centering the cuff's bladder approximately 1 inch above the site where the brachial pulse has been palpated helps ensure even cuff inflation over the brachial artery. A mercury manometer needs to be at eye level because improper height can alter perception of reading. However, this does not apply to an aneroid manometer.
Answer to Question 2
C
Feedback:
The HIV-RNA, or viral load, is measured to determine how virulent the virus is. A person who is not infected with HIV has an undetectable viral load. An undetectable reading is also considered to be an excellent response to therapy, although the inability to detect the virus in the blood does not indicate that a person is no longer infected. Clients with HIV that is not controlled with medications may have readings as high as 1,000,000 copies or more of viral cells read as viral load.
