Answer to Question 1

Correct Answer: 2,3
Rationale 1: Registered nurses can administer medications but it is outside the scope of practice to prescribe medications.

Answer to Question 2

Correct Answer: 3
Rationale 1: Ionization is the chemical property of a drug, not a phase of pharmacokinetics.
Rationale 2: Bioavailability refers to the amount of active drug available to body tissues.
Rationale 3: A drug undergoes the pharmacokinetics of absorption, diffusion, metabolism, and excretion.
Rationale 4: Ionization is the chemical property of a drug where it takes on positive or negative charges.
Global Rationale: A drug undergoes the pharmacokinetics of absorption, diffusion, metabolism, and excretion. Ionization is the chemical property of a drug, not a phase of pharmacokinetics. Bioavailability refers to the amount of active drug available to body tissues. Ionization is the chemical property of a drug where it takes on positive or negative charges.
