  A) Insulin and glucose drive potassium into the cells.
  B) Insulin and glucose bind potassium to sodium.
  C) Insulin and glucose increase urinary excretion of potassium.
  D) Insulin and glucose increase fecal excretion of potassium.

Answer to Question 1

A
Feedback:
Insulin and glucose lower serum potassium levels by driving potassium into the cells. Insulin and glucose do not bind potassium to sodium or increase urinary excretion of potassium or fecal excretion of potassium.

Answer to Question 2

D
Feedback:
Beta-lactam antibacterial drugs inhibit synthesis of bacterial cell walls by binding to proteins in bacterial cell membranes. Penicillin V does not inhibit protein synthesis, cause mutations, or lower the pH of a bacterium's cellular contents.
