Answer to Question 1

increases voltage and decreases current

Rationale: Autotransformers can vary the voltage magnitude through step up or down transformers. Step up transformers will increase voltage and decrease current. Step down transformers will decrease voltage and increase current.

Answer to Question 2

scaphoid

Rationale: The scaphoid located in the proximal row of carpals, also the largest carpal in the proximal row, is most commonly fractured.
