Chapter 1 Orientation to Pharmacology

• The nurse is explaining pharmacology to a group of students. What does

pharmacology primarily study?

• How drugs are administered
• The therapeutic uses of drugs
• The effects of drugs on the body
• The cost-effectiveness of medications

Answer: C

Rationale: Pharmacology is the study of how drugs affect the body,

including mechanisms of action, therapeutic effects, and side effects.

NCLEX Focus: Basics of pharmacology

• A patient asks the nurse how medications are classified. Which of the

following is the best description of drug classification?

• Drugs are classified based on their chemical properties
• Drugs are classified based on their therapeutic uses
• Drugs are classified based on the pharmacy where they are made
• Drugs are classified based on patient age

Answer: B

Rationale: Drugs are typically classified by their therapeutic use or their

effects on particular body systems.

NCLEX Focus: Drug classification

• The nurse is preparing to administer a drug to a patient. What is the

first step in ensuring medication safety?

• Checking the patient's ID band
• Reviewing the patient's allergy history
• Confirming the drug dosage
• Reading the medication label

Answer: B

Rationale: Reviewing a patient’s allergy history is critical to prevent

allergic reactions.

NCLEX Focus: Safety - medication administration

• Which of the following is an important nursing responsibility when

administering medications?

• Determining the drug's cost
• Documenting the administration of the medication
• Calculating the pharmacy's profit
• Choosing the manufacturer 2 / 4

Answer: B

Rationale: Proper documentation of medication administration is a crucial

nursing responsibility to ensure patient safety and legal accuracy.

NCLEX Focus: Medication administration

• A nurse is explaining the difference between generic and brand-name

drugs. What is the key difference?

• Generic drugs have different active ingredients
• Brand-name drugs are less effective
• Generic drugs are usually less expensive
• Brand-name drugs are safer

Answer: C

Rationale: Generic drugs typically cost less but have the same active

ingredients as brand-name drugs.

NCLEX Focus: Drug classification

• The nurse is assessing a patient who is taking multiple medications.

What term is used to describe the use of multiple medications by a patient?

• Monotherapy
• Polypharmacy
• Drug synergy
• Tolerance

Answer: B

Rationale: Polypharmacy refers to the use of multiple medications, often

seen in older adults or patients with chronic conditions.

NCLEX Focus: Safety - polypharmacy

• Which of the following factors is most likely to affect a drug's

absorption?

• The patient's gender
• The route of administration
• The patient's eye color
• The patient's job

Answer: B

Rationale: The route of administration (oral, IV, etc.) has a significant

impact on the absorption rate of a drug.

NCLEX Focus: Pharmacokinetics - absorption

• A nurse is reviewing the concept of bioavailability with a patient. What

does bioavailability refer to?

• The time it takes for a drug to work
• The percentage of the drug that reaches the bloodstream
• The amount of the drug metabolized by the liver 3 / 4

• The effect of the drug on target cells

Answer: B

Rationale: Bioavailability refers to the proportion of a drug that enters the

bloodstream and is available for action.

NCLEX Focus: Pharmacokinetics - bioavailability

• The nurse is caring for a patient who has taken an overdose of a

medication. What term describes the harmful effects of a drug when taken in excessive amounts?

• Tolerance
• Toxicity
• Dependence
• Resistance

Answer: B

Rationale: Toxicity occurs when a drug is taken in excessive amounts,

leading to harmful effects.

NCLEX Focus: Safety - overdose and toxicity

• The nurse is explaining drug distribution to a patient. Which of the

following is most important for drug distribution in the body?

• The drug’s half-life
• Blood flow to tissues
• The color of the drug
• The route of administration

Answer: B

Rationale: Blood flow to tissues is essential for proper distribution of the

drug throughout the body.

NCLEX Focus: Pharmacokinetics - distribution

• A nurse is caring for a patient with liver disease. How might liver

disease affect drug metabolism?

• The drug will be excreted faster
• The drug will be metabolized slower
• The drug will have no effect on the body
• The drug will work faster

Answer: B

Rationale: Liver disease can impair drug metabolism, leading to a slower

breakdown of drugs and potential drug accumulation.

NCLEX Focus: Pharmacokinetics - metabolism

• Which of the following describes the process of a drug being broken

down and converted to an inactive form in the body?

• Absorption
• Distribution
