Which type of error is it when the wrong type of medication is administered to the patient?

Choice A reason: This is incorrect. The PCA will not give additional pain medication whenever the button is pushed. The PCA is programmed to deliver a specific dose of pain medication at a specific interval. If the button is pushed before the interval is over, the PCA will not release any medication. This is to prevent overdose and side effects.

Choice B reason: This is incorrect. The PCA will not deliver medication through the IV until the pain is all gone. The PCA is designed to provide pain relief, not pain elimination. The PCA has a limit on how much medication it can deliver in a certain period of time. The patient may still have some pain even after using the PCA.

Choice C reason: This is correct. You or a designated family member are the only one who gets to push the PCA button-nobody else may do so. The PCA is intended to give the patient control over their pain management. The patient should push the button when they feel pain, not when someone else thinks they need it. Allowing others to push the button can lead to under- or over-medication, which can be harmful.

Choice D reason: This is incorrect. Wait until the pain becomes severe before pushing the PCA button is not a good instruction. The PCA is more effective when the patient pushes the button before the pain becomes too intense. Waiting too long can make the pain harder to control and require more medication. The patient should use the PCA as needed to keep the pain at a tolerable level..

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.
