Correct Answer: A

Rationale: Keeping the client's bed in the lowest position is an essential measure to prevent falls. Lowering the bed reduces the risk of injury if the client falls out of bed by decreasing the distance of the fall. Encouraging the client to wear non-slip socks (Choice B) may help prevent slips on smooth surfaces but does not address the risk of falls in other scenarios. Placing a fall risk sign on the client's door (Choice C) alone does not actively prevent falls but serves as a warning. Using a gait belt when ambulating the client (Choice D) is important for assisting with mobility but does not directly address fall prevention in the client's environment.

Correct Answer: B

Rationale: The nurse demonstrated responsibility by recognizing the potential harm of administering an antibiotic the client is allergic to and taking the necessary steps to ensure the client's safety. Choice A, 'Fairness,' is not applicable in this scenario as it does not involve treating individuals equitably. Choice C, 'Risk-taking,' is incorrect as the nurse's actions aimed to minimize risks rather than taking them. Choice D, 'Creativity,' is not the best fit as the nurse's actions focused on following established protocols and ensuring patient safety rather than thinking innovatively.

Correct Answer: A

Rationale: The correct answer is to regulate O2 via nasal cannula no more than 6L. This flow rate is generally recommended to ensure adequate oxygen delivery without causing discomfort or potential harm to the patient. Choices B, C, and D are incorrect as they suggest flow rates that are either too low (2L, 4L) or too high (8L). A flow rate of 2L might not provide sufficient oxygen, while 4L could be inadequate for some patients. On the other hand, a flow rate of 8L could be excessive and potentially harmful, leading to complications like oxygen toxicity. Therefore, the optimal recommendation is to regulate O2 via nasal cannula at a maximum of 6L to balance effectiveness and safety.

Correct Answer: A

Rationale: The correct answer is A because cleaning the outside part of hearing aids with a damp cloth is an appropriate method. Rubbing alcohol can damage ear molds, so choice B is incorrect. Keeping the volume of hearing aids turned up high may lead to discomfort, making choice C incorrect. Removing batteries when not in use at night is good practice for battery life, but it does not directly relate to understanding cleaning instructions, so choice D is less relevant in this context.

Correct Answer: A

Rationale: The correct first action for the nurse to take when a client removes the covering from an ice pack is to observe the appearance of the skin under the ice pack. This assessment is crucial to check for any skin damage or adverse reactions resulting from direct contact with the ice pack. Instructing the client about the importance of the covering (Choice B) can follow the skin assessment. Reapplying the covering (Choice C) before skin assessment may potentially cause harm. Asking the client about the duration of ice application (Choice D) is not the immediate priority; ensuring skin integrity is the primary concern.
