MMSC 436 Practice - Drugs & Toxicology
Exam Questions & Answers (Grade A+)
When a drug concentration exceeds the available metabolic
capacity of the body, what does the drug's metabolism become
dependent on?
-The amount of metabolizing enzyme
-The health of the renal system
-The number of doses given per hour
-The drug concentration itself -
correct answer ✅The amount of metabolizing enzyme

disorders?
-Lithium
-Acetaminophen
-Phenytoin
-Digoxin -
correct answer ✅Lithium
Which of the following could account for drug toxicity following a
prescribed dose?
-Using a single drug as opposed to multiple drugs for treatment
,MMSC 436 Practice - Drugs & Toxicology
Exam Questions & Answers (Grade A+)
-Decreased renal elimination leading to increased free drug
concentration
-Increased drug metabolism caused by central nervous system
disease
-Using a different route of administration than is typically used for
that drug -
correct answer ✅Decreased renal elimination leading to increased
free drug concentration
The fraction of drug absorbed into a physiological system that is
based on the amount of drug given is referred to as:
-volume of distribution.
-bioavailability.
-dosing.
-steady state. -
correct answer ✅bioavailability.
If a drug is acidic in nature, which of the following proteins will it
associate with primarily for transport and distribution?
-Lipoprotein
-α1-Glycoprotein

Exam Questions & Answers (Grade A+)
-Albumin
-All of the above -
correct answer ✅Albumin
The therapeutic range of a drug is:
-dependent on the route of drug administration.
-dependent on renal function.
-the range of concentrations within which the drug is effective yet
not toxic.
-the range of concentrations at which there are no drug
interactions. -
correct answer ✅the range of concentrations within which the
drug is effective yet not toxic.
The period of time during which the concentration of a therapeutic
drug decays by 50% is referred to as the drug's:
-half-life.
-dosing curve.
-subtherapeutic range.
-volume of distribution. -
correct answer ✅half-life
