NUR 210 Exam 2 Actual Questions and
Correct Answers (Verified Answers) Already
Graded A+ | New Update 2026/2027
Question 1
The study of how drugs affect the body is called:
A) Pharmacokinetics
B) Pharmacodynamics
C) Toxicology
D) Biochemistry
Correct Answer: B) Pharmacodynamics
Rationale: Pharmacodynamics explains the drug's effect on the body, including mechanisms of
action and receptor interactions .
Question 2
The process of drug absorption, distribution, metabolism, and excretion is:
A) Pharmacodynamics
B) Pharmacokinetics
C) Pharmacotherapeutics
D) Pharmacogenetics
Correct Answer: B) Pharmacokinetics
Rationale: Pharmacokinetics describes what the body does to the drug throughout its journey .
Question 3
The liver is primarily responsible for:
A) Excretion
B) Metabolism
,C) Absorption
D) Distribution
Correct Answer: B) Metabolism
Rationale: The liver is the primary site for drug metabolism through enzymatic processes .
Question 4
The kidney is the main organ for:
A) Absorption
B) Excretion
C) Metabolism
D) Storage
Correct Answer: B) Excretion
Rationale: The kidneys filter blood and eliminate drugs and their metabolites through urine .
Question 5
The first-pass effect mainly affects which route?
A) IV
B) IM
C) Oral
D) Sublingual
Correct Answer: C) Oral
Rationale: Oral drugs are absorbed from the GI tract and pass through the liver via the portal
circulation before reaching systemic circulation, potentially reducing bioavailability .
Question 6
The time it takes for a drug's plasma concentration to decrease by 50% is:
A) Duration
B) Peak time
,C) Half-life
D) Onset
Correct Answer: C) Half-life
Rationale: Half-life determines dosing frequency and time to reach steady state .
Question 7
A drug with a narrow therapeutic index requires:
A) Larger doses
B) No monitoring
C) Frequent serum level checks
D) Minimal assessment
Correct Answer: C) Frequent serum level checks
Rationale: Narrow therapeutic index means small changes in dose can lead to toxicity or
therapeutic failure .
Question 8
Which route gives 100% bioavailability?
A) Oral
B) IV
C) IM
D) Rectal
Correct Answer: B) IV
Rationale: Intravenous administration bypasses absorption barriers, delivering the entire dose
directly into the bloodstream .
Question 9
Which factor can slow drug absorption?
A) Increased blood flow
B) Food in stomach
, C) Warm temperature
D) IM route
Correct Answer: B) Food in stomach
Rationale: Food can delay gastric emptying and alter drug absorption rates .
Question 10
The steady-state level of a drug occurs when:
A) Intake equals elimination
B) Dose increases
C) Absorption stops
D) Excretion stops
Correct Answer: A) Intake equals elimination
Rationale: Steady state is achieved when the amount administered equals the amount eliminated
per dosing interval .
Question 11
Drugs that mimic the body's natural chemicals are called:
A) Antagonists
B) Agonists
C) Inhibitors
D) Blockers
Correct Answer: B) Agonists
Rationale: Agonists bind to receptors and produce a response similar to endogenous substances .
Question 12
Drugs that block receptor response are called:
A) Agonists
B) Antagonists
