Choice D is inaccurate (calcium not the issue).

Correct Answer: C

Rationale:
Choice C is correct because lipid solubility affects gastric drug absorption by determining how easily a drug crosses the stomach's lipid membranes, a key pharmacokinetic factor.
Choice A is incorrect as liver enzyme activity impacts metabolism, not gastric absorption.
Choice B is wrong because protein binding affects distribution, not initial absorption.
Choice D is incorrect since chewing and swallowing influence administration, not the absorption process in the stomach.

Correct Answer: D

Rationale:
Choice D is correct because REMS often require provider enrollment, training (e.g., opioid prescribing), and patient counseling to mitigate risks, per FDA mandates.
Choice A is incorrect alone as enrollment is one step.
Choice B is wrong by itself because training is just part.
Choice C is incorrect solo since counseling is only one duty.

Correct Answer: D

Rationale:
Choice D is correct because Lexicomp offers pediatric dosing, Medline provides research, and PDR includes label data—all valuable for pediatric drug info.

Choice B is wrong by itself because it's research-focused.
Choice C is incorrect solo since PDR is label-specific.

Correct Answer: C

Rationale:
Choice C is correct because medication agreements are recommended when drug-seeking behavior is suspected, helping set boundaries and monitor use in high-risk cases.
Choice A is incorrect as universal use isn't practical or necessary for all chronic pain.
Choice B is wrong because repeated requests alone don't always warrant a contract without suspicion.
Choice D is incorrect since cancer pain typically doesn't require contracts unless misuse is suspected.
