Rationale: The correct answer is B because the U.S. Bureau of Labor Statistics predicts that the job growth rate for RNs will surpass job growth in all other occupations by 2020. This is supported by the increasing demand for healthcare services due to an aging population and advancements in medical technology.

Correct Answer: A

Rationale: The correct answer is A because large doses of calcium causing cerebral plaques to form can potentially mask the atrophy of the brain, which is a common indicator of dementia on imaging studies. This interference could delay the detection of dementia. Choice B is incorrect because excess folic acid would not mask a vitamin B deficiency that could lead to dementia. Choice C is incorrect as hypnotherapy focusing on current thoughts would not necessarily eliminate clues to past cognitive decline. Choice D is incorrect because there is no evidence that the electrical current from magnetic fields interferes with normal brain waves in a way that would cause confusion and inability to concentrate.

Correct Answer: B

Rationale: The correct answer is B: Child abuse.

Explanation for incorrect choices: A: Animal abuse - While animal abuse is also a serious concern, nurses are not legally required to report it in the same way as child abuse. C: Alcohol abuse - Nurses may provide assistance and support for individuals struggling with alcohol abuse, but it is not a mandatory reporting requirement. D: Infant abuse - While abuse of infants falls under the category of child abuse, the specific term "infant abuse" is not a separate reporting requirement for nurses.
