Quizlet Pharmacology Questions for LPN Questions
Question 1 of 5
Instructions to a client regarding self-administration of oral enteric-coated tablets should include which of the following statements?
Correct Answer: D
Rationale:
Choice D is correct because enteric-coated tablets need ample fluid (e.g., 8 ounces) to ensure proper passage and dissolution in the intestines, not stomach, for optimal effect.
Choice A is incorrect as avoiding other drugs isn't a general rule unless specified.
Choice B is wrong because dissolving enteric-coated tablets destroys their protective coating.
Choice C is incorrect since crushing negates the coating's purpose.
Question 2 of 5
In deciding which of multiple drugs used to use to treat a condition, the NP chooses Drug A because it:
Correct Answer: C
Rationale:
Choice C is correct because choosing a drug covered by insurance ensures affordability and adherence, a practical consideration in rational drug selection.
Choice A is incorrect as serious side effects typically deter use unless benefits outweigh risks, especially for non-life-threatening conditions.
Choice B is wrong because dosing and location are secondary to efficacy and cost.
Choice D is incorrect since insurance coverage is a valid factor.
Question 3 of 5
Pharmacokinetic changes in children that affect drug dosing include:
Correct Answer: D
Rationale:
Choice D is correct because children have higher gastric pH (affects absorption), slower liver metabolism (prolongs drug action), and more body water (alters distribution), all impacting dosing per pediatric pharmacology.
Choice A is incorrect alone as pH is one factor.
Choice B is wrong by itself because metabolism is just part.
Choice C is incorrect solo since body water is only one aspect.
Question 4 of 5
Gender factors that affect drug prescribing include:
Correct Answer: D
Rationale:
Choice D is correct because body composition (fat vs. lean mass), hormone levels (e.g., estrogen affecting metabolism), and enzyme activity (e.g., CYP differences) all influence prescribing by sex.
Choice A is incorrect alone as it's one factor.
Choice B is wrong by itself because hormones are just part.
Choice C is incorrect solo since enzymes are only one aspect.
Question 5 of 5
Schedule III drugs are characterized by:
Correct Answer: B
Rationale:
Choice B is correct because Schedule III drugs (e.g., anabolic steroids) have moderate abuse potential, less than Schedule II, with medical use, per DEA.
Choice A is incorrect as high potential is Schedule II.
Choice C is wrong because low potential is Schedule IV.
Choice D is incorrect since only B applies.
