A nurse is preparing to insert an IV catheter for an adult client. Which of the following actions should the nurse take?

Choice A reason:
Placing the wasted portion of the controlled substance in the sharp container is not correct. Wasted controlled substances should be disposed of according to specific regulations and facility protocols.
Choice B reason:
Asking a second nurse to record her signature when wasting an unused portion of the controlled substance is not a standard practice. The process for wasting controlled substances usually involves following specific documentation procedures, but this does not necessarily require a second nurse's signature.
Choice C reason:
Verifying the count total of the controlled substance after removing the amount needed is the appropriate action. When administering a controlled substance, it is crucial to maintain accurate accountability of the medication. This includes verifying the count total of the controlled substance before and after removing the amount needed for administration. This step helps ensure proper documentation, prevent errors, and maintain appropriate control over controlled substances.
Choice D reason:
Reporting any discrepancy in the count total of the controlled substance after administration is important, but it should be done as a separate step from verifying the count total before administration. Discrepancies should be reported according to facility policy to ensure proper investigation and resolution.

Choice A reason:
Protective precautions are not necessary because they (also known as reverse isolation) are used for immunocompromised clients to protect them from potential pathogens carried by healthcare workers or visitors.
Choice B reason:
Droplet precautions are not necessary because they are used for infections spread through larger respiratory droplets, like influenza or pertussis.
Choice C reason:
Airborne precautions should be implemented by the nurse. Tuberculosis (TB) is primarily transmitted through the airborne route, as the bacteria that cause TB can be suspended in the air as tiny particles (droplet nuclei) when an infected person coughs, sneezes, speaks, or sings. These particles can be inhaled by others, leading to the potential transmission of the disease.
Choice D reason:
Contact precautions are not necessary because they are used for infections that are transmitted through direct contact with the client or contaminated surfaces, such as MRSA (Methicillin-resistant Staphylococcus aureus) or C. difficile.
