NRG 200: PHARMACOLOGY FOR HUMAN CARING
NURSING
ULTIMATE EXAM PREP PACKAGE 2026
### SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS
(Questions 1-40)
**Question 1**
A nurse is reviewing the medication administration record and notes a
medication is ordered to be given "PC." When should the nurse
administer this medication?
A) Before meals
B) At bedtime
C) After meals
D) As needed
**Correct Answer: C) After meals**
,**Rationale:** "PC" is an abbreviation for *post cibum*, Latin for "after
meals." "Before meals" is AC (*ante cibum*), "at bedtime" is HS (*hora
somni*), and "as needed" is PRN (*pro re nata*).

**Question 2**
The study of how a drug moves through the body, including absorption,
distribution, metabolism, and excretion, is known as:
A) Pharmacodynamics
B) Pharmacokinetics
C) Pharmacotherapeutics
D) Pharmacogenomics
**Correct Answer: B) Pharmacokinetics**
**Rationale:** Pharmacokinetics describes what the body does to the
drug—its movement through absorption, distribution, metabolism, and
excretion. Pharmacodynamics describes what the drug does to the
body.

**Question 3**
,A patient is prescribed a medication that has a high first-pass effect.
The nurse understands this means:
A) A large portion of the drug is inactivated by the liver before reaching
systemic circulation
B) The drug is absorbed quickly from the stomach
C) The drug is excreted unchanged by the kidneys
D) The drug has a rapid onset of action
**Correct Answer: A) A large portion of the drug is inactivated by the
liver before reaching systemic circulation**
**Rationale:** The first-pass effect refers to the metabolism of a drug
by the liver before it reaches systemic circulation, often necessitating
higher oral doses.
---
**Question 4**
Which organ is primarily responsible for drug metabolism in the body?
A) Heart
B) Lungs
C) Liver
D) Kidney
, **Correct Answer: C) Liver**
**Rationale:** The liver is the primary site of drug metabolism,
containing enzymes (primarily the cytochrome P450 system) that
transform drugs into forms that can be more easily eliminated from the
body.
---
**Question 5**
Which organ is primarily responsible for drug excretion from the body?
A) Liver
B) Lungs
C) Kidney
D) Skin
**Correct Answer: C) Kidney**
**Rationale:** The kidneys are the primary organs responsible for drug
excretion, eliminating water-soluble drug metabolites through urine.
Other routes include bile, lungs, sweat, and breast milk.
