Rationale: The correct answer is D because pursed lip breathing helps prevent airway collapse by maintaining positive pressure in the airways, reduces anxiety by promoting relaxation, and enhances effective breathing by improving oxygen exchange. Choice A is incorrect as pursed lip breathing does not directly prevent the build-up of secretions. Choice B is incorrect as comfort is not the primary purpose of pursed lip breathing. Choice C is incorrect as while pursed lip breathing can improve respiratory muscle function, its primary benefit lies in preventing airway collapse, reducing anxiety, and promoting effective breathing.

C is incorrect as many cases of elder abuse go unreported due to various reasons such as fear, shame, or lack of awareness. D is incorrect as healthcare practitioners are mandated to report any suspected cases of elder abuse, not just verified cases, to protect the well-being of the elderly.

Correct Answer: B

Rationale: The correct answer is B because multimorbidity refers to the presence of multiple chronic conditions in an individual, which can complicate treatment due to interactions between medications, conflicting treatment recommendations, and the need for coordination among different healthcare providers. Managing multiple health conditions and medications can lead to potential adverse effects, drug interactions, and difficulties in prioritizing treatment goals. Choices A, C, and D are incorrect because multimorbidity actually increases treatment complexity, necessitating individualized care plans and careful consideration of potential interactions between treatments.
