Quizlet Pharmacology Questions for LPN Questions
Question 1 of 5
Nurse practitioner practice may thrive under health-care reform because of:
Correct Answer: A
Rationale:
Choice A is correct because studies show NPs provide cost-effective care with outcomes comparable to physicians, aligning with healthcare reform's focus on value and efficiency.
Choice B is incorrect as independent practice isn't guaranteed by reform; it depends on state laws.
Choice C is wrong because full reimbursement isn't universally promised and varies by system.
Choice D is incorrect since shifting Medicaid costs is a policy issue, not a direct driver of NP practice thriving.
Question 2 of 5
A laboratory result indicates that the peak level for a drug is above the minimum toxic concentration. This means that the:
Correct Answer: B
Rationale:
Choice B is correct because a peak level above the minimum toxic concentration indicates the drug concentration exceeds the safe therapeutic range, likely causing adverse effects.
Choice A is incorrect as therapeutic effects occur below toxicity, not above.
Choice C is wrong because shortening doses doesn't address an already toxic level; dose reduction is needed.
Choice D is incorrect since duration isn't the issue—peak concentration is.
Question 3 of 5
Once they have been metabolized by the liver, the metabolites may be:
Correct Answer: D
Rationale:
Choice D is correct because liver metabolism can produce metabolites that are more active (e.g., prodrugs like codeine to morphine), less active, or inactive, depending on the drug, making all options possible.
Choice A is incorrect as it's only one scenario, not the full range.
Choice B is wrong because it excludes cases where metabolites are more active.
Choice C is incorrect since not all metabolites are deactivated—some retain or gain activity.
Question 4 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 5 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.
