Sample item

Before extubation after nondepolarizing neuromuscular blockade, which quantitative train-of-four ratio best supports adequate recovery?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. At least 0.9

A quantitative train-of-four ratio of at least 0.9 is used to indicate adequate recovery from nondepolarizing blockade. Lower ratios are associated with residual weakness and increased risk of postoperative airway and respiratory complications.

Option by option

  • A. At least 0.9 (correct)

    Correct. A ratio of 0.9 or greater is the usual recovery target.

  • B. 0.4

    A ratio of 0.4 indicates substantial residual weakness.

  • C. 0.2

    A ratio of 0.2 represents profound residual block.

  • D. 0.6

    A ratio of 0.6 remains below the accepted recovery threshold.
