Which option correctly lists the asymmetrical alarm widths with the arterial width paired with venous width as 120 and 100 respectively?

Which option correctly lists the asymmetrical alarm widths with the arterial width paired with venous width as 120 and 100 respectively?

• A. Arterial width 100; Venous width 120
• B. Arterial width 110; Venous width 90
• C. Arterial width 130; Venous width 110
• D. Arterial width 120; Venous width 100

Answer: (D)

Understanding asymmetrical alarm widths means each dialysis line has its own tolerance for deviation before an alarm triggers. Here, the required pairing is arterial width 120 with venous width 100. The option that lists arterial width 120 and venous width 100 matches exactly, so it’s the correct choice. The other options do not keep the arterial value at 120 paired with venous 100 (they swap values or use different numbers), which is why they don’t fit the requirement.
