Rationale: The correct answer is C: 'Avoid open flames or smoking near oxygen.' This information is crucial to prevent fires because oxygen supports combustion. Choices A, B, and D are incorrect. Choice A is not relevant to oxygen therapy. Choice B is incorrect as oxygen should not be turned off when in use as prescribed. Choice D is incorrect because adjusting the oxygen flow rate without healthcare provider guidance can be dangerous.

Correct Answer: C

Rationale: After administering a narcotic medication, any unused portion should be discarded with another nurse as a witness. This procedure ensures proper disposal of controlled substances and prevents misuse or diversion. Storing it for later use (Choice B) is not appropriate due to safety concerns and legal regulations. Returning it to the pharmacy (Choice D) is also not recommended as the medication is already out of the pharmacy's control. Documenting the amount wasted (Choice A) is important for accurate record-keeping but does not address the immediate need for safe disposal of the unused narcotic medication.

Correct Answer: B

Rationale: The correct answer is 'Increased hematocrit.' In fluid volume deficit (FVD), there is a decrease in the amount of fluid in the blood vessels, leading to hemoconcentration. This results in an increase in hematocrit levels. Choices A, C, and D are incorrect because a decrease in hematocrit, decrease in white blood cell count, and an increase in red blood cell count are not typically seen in fluid volume deficit.

Correct Answer: B

Rationale: The correct answer is B. When instructing a client on the use of a cane, it is essential to ensure that the cane has a rubber tip. This rubber tip helps prevent slipping, providing additional stability and safety. Option A, holding the cane on the weaker side, is incorrect as the cane should be held on the stronger side to provide better balance and support. Option C, keeping the cane on the dominant side, is also incorrect because the cane should be held on the stronger side. Option D, using the cane only on stairs, is not comprehensive as the cane can be used for support and balance while walking on level ground as well.

Correct Answer: D

Rationale: The correct answer is D: Lowered immune function. Older adults often experience a decline in immune function as they age, making them more vulnerable to infections. This weakened immune system can result in increased susceptibility to various pathogens. Choice A, 'Improved nutritional status,' is incorrect because good nutrition can actually help support the immune system. Choice B, 'Increased mobility,' is not directly related to an increased risk of infections. Choice C, 'Chronic conditions,' while they can contribute to a weakened immune system, do not directly address the primary risk factor for infections in older adults.
