Answer to Question 1

B
Feedback:
Exocytosis is the movement of substances such as waste products, hormones, and neurotransmitters out of the cell. Pinocytosis is the movement of nutrients and needed substances into the cell through specific receptors on the cell surface. Phagocytosis involves the destruction of engulfed proteins or bacteria. Endocytosis involves incorporation of material into the cell.

C

The patient will take 90 mg/dose (360 divided by 4 doses equals 90 mg/dose). Therefore, the other options are incorrect.
