Question 1 of 9

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 2 of 9

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 9

Pharmaceutical promotion may affect prescribing. To address the impact of pharmaceutical promotion, the Institute of Medicine recommends that:

Correct Answer: A

Rationale: Choice A is correct because the Institute of Medicine recommends transparency in conflicts of interest to reduce bias in prescribing education, promoting objectivity. Choice B is incorrect as banning reps isn't a universal recommendation—disclosure is preferred. Choice C is wrong because samples aren't tied to insurance status in this context. Choice D is incorrect since even low-value gifts can influence, and disclosure is the broader solution.

Question 4 of 9

Precautions that should be taken when prescribing controlled substances include:

Correct Answer: B

Rationale: Choice B is correct because tamper-proof paper helps prevent prescription fraud, a key precaution for controlled substances prone to abuse. Choice A is incorrect as faxing Schedule II prescriptions is restricted—originals are typically required. Choice C is wrong because pre-signed pads are insecure and discouraged. Choice D is incorrect since numbers alone don't enhance security and may confuse.

Question 5 of 9

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 6 of 9

Digoxin may cause a type A adverse drug reaction due to:

Correct Answer: B

Rationale: Choice B is correct because digoxin's narrow therapeutic index means small dose increases can lead to type A ADRs (predictable, dose-related), like toxicity. Choice A is incorrect as idiosyncratic effects are type B, not A. Choice C is wrong because teratogenicity isn't a type A reaction—it's a specific harm. Choice D is incorrect since digoxin isn't a carcinogen; its ADRs are cardiovascular.

Question 7 of 9

Patients may prefer brand-name drugs over generics due to:

Correct Answer: A

Rationale: Choice A is correct because some patients perceive brand-name drugs as higher quality due to marketing or familiarity, despite bioequivalence. Choice B is incorrect as generics are cheaper, not brand-name. Choice C is wrong because side effects are equivalent. Choice D is incorrect since only A applies.

Question 8 of 9

Drugs that are safe for breastfeeding include:

Correct Answer: B

Rationale: Choice B is correct because acetaminophen is safe for breastfeeding, with low milk levels and no significant infant effects, per AAP guidelines. Choice A is incorrect as fluoxetine's milk transfer risks infant exposure. Choice C is wrong because isotretinoin isn't safe—it's contraindicated in breastfeeding due to toxicity. Choice D is incorrect since only acetaminophen is safe.

Question 9 of 9

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.
