Correct Answer: B

Rationale: Pain tolerance in elderly clients with cancer is likely to decrease due to factors such as diminished adaptative capacity, increased physical discomfort, and the psychological impact of the disease. Cancer is known to cause various physical and emotional stressors that can lower the pain threshold, leading to a decrease in pain tolerance. Choices A, C, and D are incorrect because cancer and its associated effects typically result in a decrease in pain tolerance rather than remaining constant, increasing, or having no impact.

Correct Answer: A

Rationale: The correct response is to show cultural awareness and respect the client's request by offering assistance in arranging for the medicine woman to be present. This approach acknowledges the importance of cultural beliefs and practices in the client's care, fostering trust and cooperation. Choices B, C, and D are inappropriate as they dismiss or belittle the client's cultural beliefs, showing insensitivity and lack of respect, which can negatively impact the nurse-client relationship.

Correct Answer: B

Rationale: The correct answer is Standard Precautions. Standard precautions are taken in all situations for all clients and involve all body secretions except sweat. They are designed to reduce the rate of transmission of microbes from one host to another or one source to another. Respiratory Isolation (Choice A) is used for diseases transmitted by airborne particles, not secretions and blood. Contact Isolation (Choice C) is for clients known or suspected to be infected with microorganisms that can be transmitted by direct or indirect contact. Droplet Isolation (Choice D) is used for diseases transmitted by large respiratory droplets expelled during coughing, sneezing, talking, or procedures.

Correct Answer: B

Rationale: The correct answer is 'To provide data for analysis by a risk manager to determine how future problems can be avoided.' Incident reports are a crucial tool for collecting information about incidents to analyze them and prevent similar issues in the future. They are not primarily used for liability protection or disciplining staff. Therefore, choices A and C are incorrect. Selecting 'All of the above' (choice D) is not accurate as incident reports serve a specific purpose related to data analysis and risk prevention, excluding liability protection and staff discipline.

Correct Answer: C

Rationale: The correct answer is 6 liters/minute. When a client needs oxygen therapy, the highest flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Higher flow rates must be delivered by a mask. Choices A, B, and D are incorrect because they suggest flow rates that exceed what can be effectively delivered through a nasal cannula.
