Question 2 of 5
A patient receives an inhaled corticosteroid to treat asthma. The patient asks the primary care NP why the drug is given by this route instead of orally. The NP should explain that the inhaled form:

Choice B is wrong since bioavailability is sufficient at the site.
Choice D is inaccurate as dosing regulation isn’t necessarily easier.
Question 3 of 5

Correct Answer: B
Rationale:
Choice B is correct because START (Screening
Tool to Alert to Right Treatment) identifies underused beneficial drugs (e.g., statins) in the elderly, per guidelines.

Choice C is wrong because it's not about levels.
Choice D is incorrect since only B fits.
Question 4 of 5
Food or drink that should be avoided when taking a prescription for warfarin includes:
Correct Answer: D
Rationale:

Choice A is incorrect as milk doesn't significantly affect warfarin.
Choice B is wrong because orange juice has no notable interaction.
Choice C is incorrect since grapefruit juice impacts CYP3A4 drugs, not warfarin's VKORC1 mechanism.
Question 5 of 5
The therapeutic goals when prescribing include(s):
Correct Answer: D
Rationale:
Choice D is correct because therapeutic goals can be curative (healing), palliative (symptom relief), or preventive (disease avoidance), depending on the patient's condition, making all options valid.
Choice A is incorrect as it's only one goal, not all.
Choice B is wrong because it excludes curative and preventive aims.
Choice C is incorrect since it misses curative and palliative goals.
