Which medication order will provide the most consistent control of the patient's chronic pain?

Choice A reason: This is incorrect. Wiping up the liquid with paper towels and gloves can spread the mercury droplets and increase the risk of exposure. Mercury can also penetrate through nitrile gloves and cause skin irritation.

Choice B reason: This is incorrect. Disinfecting the area with chlorine bleach can create toxic vapours that can harm the respiratory system. Chlorine bleach is not effective in removing mercury from the surface.

Choice C reason: This is incorrect. Contacting the housekeeping staff to mop up the liquid can delay the proper clean-up and disposal of mercury. Mopping can also disperse the mercury droplets and contaminate the mop and the water.

Choice D reason: This is correct. Consulting the agency’s materials safety data sheets (MSDS) is the priority action of the nurse. MSDS provide information on the hazards, precautions, and procedures for handling and disposing of mercury. The nurse should follow the MSDS guidelines and use the appropriate equipment and methods to clean up the spill.

Choice A reason: This is an incorrect choice because the nurse braids the patient’s long hair to prevent tangles is not an action that demonstrates the concept of nurse autonomy. Nurse autonomy refers to the ability and right of nurses to make independent decisions about patient care without interference from others. Braiding the patient’s hair is a personal care task that does not require the nurse to use their own judgment or expertise.

Choice B reason: This is the correct choice because the nurse checks the policy manual before changing the central line dressing is an action that demonstrates the concept of nurse autonomy. Nurse autonomy refers to the ability and right of nurses to make independent decisions about patient care without interference from others. Checking the policy manual before changing the central line dressing shows that the nurse is responsible for following the evidence-based guidelines and standards of practice for this procedure.

Choice C reason: This is an incorrect choice because the nurse counts the patient’s pulse before administering digoxin is not an action that demonstrates the concept of nurse autonomy. Nurse autonomy refers to the ability and right of nurses to make independent decisions about patient care without interference from others. Counting the patient’s pulse before administering digoxin is a routine task that is prescribed by the physician and does not involve the nurse’s own decision making.

Choice D reason: This is an incorrect choice because the nurse directs the nursing assistant to obtain the patient's weight is not an action that demonstrates the concept of nurse autonomy. Nurse autonomy refers to the ability and right of nurses to make independent decisions about patient care without interference from others. Directing the nursing assistant to obtain the patient's weight is a task that is delegated by the nurse and does not reflect the nurse’s own authority or initiative.
