In reference to anatomical position, where would the scaphoid be located?
medially and proximal row
laterally and proximal row
laterally and distal row
medially and distal row
laterally and proximal row
Rationale: Anatomical position will place the thumb and radial side lateral; therefore, the scaphoid will be lateral and located in the proximal row of carpals.

Which of the following statements is not true about muscle approximation?
a. Muscle approximation involves slowly pushing the two ends of a muscle together to shorten it, then slowly lengthening the muscle. b. The approximation motion mechanically simulates the shortening that occurs during contraction, which produces a relaxation response. c. It is probable that the spindle fibers register the shortened position, which triggers a resetting of the muscle length by inducing a relaxation response. d. Muscle approximation is a technique used to increase the strength of an inhibited or stretch-weakened muscle.
During volume-assured pressure-supported ventilation, the breath will be pressure-limited under what conditions?
