ANS: A, D
Absorption by passive diffusion across the membranes depends on the pH of the environment. Increased blood flow to gastric mucosa increases absorption of medication and decreases time of absorption. Drug absorption does not depend on the mental status of the patient. Fever does not affect drug absorption. The patient's absolute weight and body surface area do not affect drug absorption, although problems associated with weight greater than or less than normal may be a factor in the process.
