Correct Answer: D

Rationale: The correct answer is D: Foods rich in vitamin K. Foods rich in vitamin K can interfere with the effectiveness of Coumadin (warfarin) by promoting blood clotting. It is crucial for clients on this medication to maintain a consistent intake of vitamin K and avoid sudden dietary changes. Choices A, B, and C are incorrect as they are not directly related to the interaction of Coumadin (warfarin) with vitamin K. Large indoor gatherings, exposure to sunlight, and active physical exercise do not have a significant impact on the effectiveness of Coumadin (warfarin) in comparison to the interaction with foods rich in vitamin K.

Correct Answer: C

Rationale: The correct topic that the nurse should include in planning a primary prevention class for adolescents is suicide risks and prevention. Adolescents are particularly vulnerable to mental health issues, including suicidal ideation. Educating them about suicide risks and prevention strategies is crucial for early intervention and support. Choices A, B, and D are important topics, but when considering primary prevention for adolescents, addressing suicide risks and prevention takes precedence due to its immediate life-saving implications.

Correct Answer: D

Rationale: A decrease in chest wall expansion suggests that the client may be experiencing a serious complication, such as worsening pneumonia or respiratory failure, requiring immediate medical attention. This finding indicates a potential decrease in lung function, which could lead to respiratory distress. Pleuritic pain on inspiration may be related to the disease process but does not indicate an immediate need for intervention. Dry mucus membranes in the mouth may require attention but are not as critical as a decrease in chest wall expansion. A decrease in respiratory rate could be concerning but is not as urgent as a decrease in chest wall expansion, which directly impacts respiratory function.

Correct Answer: A

Rationale: The correct answer is A: 'Differences in health outcomes and their determinants between different segments of the population.' Health disparity refers to variations in health status or health care utilization between different groups. Choice B is incorrect because providing equal healthcare services to all individuals is related to health equity, not health disparity. Choice C is also incorrect as it refers to universal access to healthcare, which is different from health disparity. Choice D is incorrect as it describes the concept of high-quality healthcare for everyone, not health disparity.

Correct Answer: C

Rationale: Individuals with cognitive impairment often experience difficulties in learning new information, creative thinking, and making sound judgments. Loss of ability in hearing, speech, and sight (Choice A) is more closely related to sensory impairments rather than cognitive impairment. Endurance, strength, and mobility (Choice B) are more associated with physical capabilities rather than cognitive functions. Balance, flexibility, and coordination (Choice D) are related to motor skills and physical coordination, not cognitive impairment.
