CNOR Test Dates and Scheduling

Initial HIV post-exposure prophylaxis must begin immediately, ideally within two hours, to maximize efficacy. Option A is correct because early intervention prevents viral replication. Option B is incorrect; while baseline serology is necessary, waiting for results delays critical medication administration. Option C is wrong because delaying until the shift ends misses the optimal efficacy window. Option D is incorrect because waiting for the source patient's viral load results unnecessarily delays time-sensitive treatment. Early antiretroviral initiation and immediate risk assessment are the cornerstones of effective post-exposure management.

The patient's obesity and residual lower-extremity weakness from spinal anesthesia preclude active weight-bearing. Using the built-in slider board minimizes friction and shearing forces, and with four staff to guide the move, it is the safest method. A draw sheet (Option A) can be effective but requires more effort and may not reduce friction as well as a slider board; however, if the slider board were unavailable, it would be appropriate. Rolling for a mechanical lift (Option B) is not standard for an OR table transfer and may cause spinal movement or discomfort. Sitting and pivoting (Option C) is dangerous due to orthostasis and profound weakness. The slider board is specifically designed for lateral transfers and should be used when available to optimize safety.

The front of the eyewear with visible bone fragments is highly contaminated. The nurse must remove it by handling only the clean earpieces, perform hand hygiene, and then remove the surgical cap by grasping the inside back to avoid contaminating the face. Options A and C are incorrect because grasping the front lens directly contaminates the hands, transferring bioburden. Option D is incorrect because pulling the cap from the front risks dragging contaminated material across the face and eyes, which is a critical error when doffing PPE at the end of the shift.
