Drugs that may cause increased adverse effects in women include:
- A. Lipid-soluble drugs
- B. Water-soluble drugs
- C. Drugs that are highly protein bound
- D. All of the above

Choice A is incorrect as lipid-soluble drugs distribute more in fat, not necessarily causing more ADRs. Choice C is wrong because protein binding isn't sex-specific enough here. Choice D is incorrect since only water-soluble drugs align.
Generic drugs may differ from brand-name drugs in:

- C. disciplining the child at mealtimes to ensure proper nutrition.
- D. making sure the child's cereals are fortified with vitamins and minerals.
Correct Answer: B
Rationale: The correct answer is B because offering variety in small portions balances nutrition over time for picky eaters. Choice A is incorrect (multivitamin if variety fails). Choice C is wrong (discipline ineffective). Choice D is inaccurate (fortified cereal not enough).

- C. NPs will be better prepared to meet emerging health care needs of patients.

Choice B is wrong since prescriptive authority depends on state laws. Choice D is inaccurate as supervision rules vary by state.
