When caring for an unconscious client with increasing intracranial pressure, the nursing intervention that is contraindicated is :

Choice A reason : Cleaning dentures in a denture cup is a standard hygiene practice but does not directly address the low WBC count. While maintaining oral hygiene is important, it is not the most critical action related to the client's immunocompromised state⁶.

Choice B reason : Replacing the water in flower vases daily is a good practice to prevent bacterial growth; however, it is recommended to avoid having flowers or plants in the room of an immunocompromised patient due to the risk of exposure to fungi and bacteria⁷.

Choice C reason : Humidifying the room can be beneficial for respiratory comfort, but it must be done with caution in immunocompromised patients. Humidifiers need to be kept clean to prevent the growth of bacteria and fungi, which could be harmful to a patient with a low WBC count⁷.

Choice D reason : Serving cooked fruit with meals is the correct action because cooking fruit can eliminate potential pathogens that the client's compromised immune system may not be able to handle. Raw fruits and vegetables can harbor bacteria and other pathogens, so serving them cooked is a safer option for someone with a low WBC count⁶⁷.

Choice A reason : Acting as if the hallucination is real can validate the client's false perceptions and potentially reinforce the hallucination. It is important to maintain a sense of reality and not to enter into the client's hallucinatory experience.

Choice B reason : Instructing the client to argue with the voices is not therapeutic. It can increase the client's agitation and anxiety, and it does not help in distinguishing reality from hallucinations.

Choice C reason : While it is important to understand the client's experience, asking direct questions about the hallucination may lead the client to focus more on the hallucination, which can reinforce its presence. The nurse should focus on reality-based topics.

Choice D reason : This is the correct action. The nurse should gently and firmly reassure the client that the hallucination is not real and is a symptom of their illness. This helps to orient the client to reality and can reduce the distress associated with hallucinations.
