Question 1
A patient is prescribed a medication that has a high first-pass effect. Which route of
administration would be MOST appropriate to bypass this effect?
A) Oral
B) Sublingual
C) Intramuscular
D) Topical
Answer: B) Sublingual
Rationale: The first-pass effect refers to metabolism of a drug in the liver after oral
absorption, reducing bioavailability. Sublingual administration allows direct
absorption into systemic circulation through the rich vascular network under the
tongue, bypassing the portal circulation and first-pass metabolism.
Question 2
The nurse is teaching a patient about a new prescription for enteric-coated tablets.
Which statement by the patient indicates correct understanding?
A) "I can crush the tablet if I have trouble swallowing."
B) "I should swallow the tablet whole without crushing or chewing."
C) "I can take the tablet with orange juice for better absorption."
D) "The coating is for flavor, so crushing is fine."
Answer: B) "I should swallow the tablet whole without crushing or chewing."
Rationale: Enteric coating protects the drug from stomach acid and prevents gastric
irritation. Crushing or chewing destroys the coating, leading to premature drug
release.
,Question 3
What is the minimum effective concentration (MEC)?
A) The maximum safe drug level
B) The plasma drug level below which therapeutic effects will not occur
C) The level at which toxicity occurs
D) The amount of drug bound to plasma proteins
Answer: B) The plasma drug level below which therapeutic effects will not occur
Rationale: The minimum effective concentration (MEC) is the plasma drug level
below which therapeutic effects will not occur. Drug levels must remain above this
threshold to achieve the desired therapeutic effect.
Question 4
What is the therapeutic index/window?
A) The dose that produces maximum effect
B) The plasma concentration between the minimum effective concentration and the
toxic concentration
C) The time it takes for the drug to be eliminated
D) The amount of drug bound to plasma proteins
Answer: B) The plasma concentration between the minimum effective
concentration and the toxic concentration
Rationale: The therapeutic range is the plasma concentration range between the
minimum effective concentration (MEC) and the minimum toxic concentration (MTC).
Maintaining drug levels within this range ensures efficacy without toxicity.
Question 5
Which of the following is an example of an adverse drug reaction?
A) Therapeutic effect
B) Desired effect
C) Unintended harmful effect
D) Dose-dependent effect
,Answer: C) Unintended harmful effect
Rationale: An adverse drug reaction is an unintended, harmful effect that occurs at
normal doses. It can range from mild to severe and may require discontinuation of
the drug.
Question 6
The term "potency" refers to:
A) The amount of drug needed to produce a given effect
B) The maximum effect a drug can produce
C) The speed at which a drug acts
D) The duration of drug action
Answer: A) The amount of drug needed to produce a given effect
Rationale: Potency refers to the amount of drug needed to produce a given effect. A
more potent drug requires a lower dose to achieve the same effect as a less potent
drug.
Question 7
A patient with liver disease may require a dose reduction of a medication because:
A) Absorption is decreased
B) Distribution is altered
C) Metabolism is impaired
D) Excretion is increased
Answer: C) Metabolism is impaired
Rationale: Liver disease impairs the liver's ability to metabolize drugs, leading to
drug accumulation and potential toxicity. Dose reductions are often necessary to
prevent adverse effects.
Question 8
A patient with chronic kidney disease may require a dose reduction because:
, A) Absorption is increased
B) Metabolism is impaired
C) Distribution is altered
D) Excretion is decreased
Answer: D) Excretion is decreased
Rationale: The kidneys are the primary route of drug excretion. In chronic kidney
disease, drug excretion is decreased, leading to drug accumulation and increased risk
of toxicity.
Question 9
The term "bioavailability" refers to:
A) The fraction of an administered drug that reaches systemic circulation
B) The rate at which a drug is absorbed
C) The amount of drug bound to plasma proteins
D) The time it takes for a drug to be eliminated
Answer: A) The fraction of an administered drug that reaches systemic
circulation
Rationale: Bioavailability is the fraction of an administered drug that reaches
systemic circulation in an unchanged form. It is 100% for intravenous drugs and
varies for other routes.
Question 10
The term "agonist" refers to a drug that:
A) Activates a receptor and produces a response
B) Blocks a receptor and prevents a response
C) Has no effect on receptors
D) Reverses the effects of another drug
Answer: A) Activates a receptor and produces a response
Rationale: An agonist is a drug that binds to a receptor and activates it, producing a
response. An antagonist blocks the receptor and prevents a response.
