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

Choice A reason: The statement that the antidote for warfarin is protamine is incorrect. The primary antidote for warfarin is Vitamin K, and in cases of significant bleeding, prothrombin complex concentrate (PCC) or fresh frozen plasma (FFP) may be used¹². Protamine is used as an antidote for heparin, not warfarin¹.

Choice B reason: Observing the client for manifestations of hemorrhage is a critical nursing action when administering warfarin. Warfarin is an anticoagulant, and one of the major risks associated with its use is bleeding. The nurse should monitor for signs such as unusual bruising, petechiae, hematuria, tarry stools, or any other indications of internal or external bleeding⁷⁸.

Choice C reason: Monitoring the client's aPTT (activated partial thromboplastin time) is not typically associated with warfarin therapy. Warfarin's effect is monitored through the prothrombin time (PT) and the International Normalized Ratio (INR), not aPTT, which is more commonly used to monitor heparin therapy⁴⁵.

Choice D reason: Warfarin should not be administered along with NSAIDs without careful consideration and monitoring due to the increased risk of bleeding. NSAIDs can affect platelet function and gastrointestinal mucosa, leading to an elevated risk of gastrointestinal bleeding when taken with warfarin¹¹¹².

Choice A reason : Tongue thrusting and lip smacking are classic signs of tardive dyskinesia (TD), a side effect of long-term use of dopamine receptor-blocking agents like haloperidol¹. TD is characterized by repetitive, involuntary, purposeless movements, primarily affecting the facial, mouth, and tongue muscles².

Choice B reason : Fine hand tremors and pill rolling are more commonly associated with Parkinson's disease, which is a different type of movement disorder. While antipsychotic medications can cause extrapyramidal symptoms that resemble Parkinson's disease, these are not indicative of tardive dyskinesia².

Choice C reason : Urinary retention and constipation can be side effects of antipsychotic medications due to their anticholinergic effects. However, these are not symptoms of tardive dyskinesia, which specifically involves involuntary movements².

Choice D reason : Loud talking and pacing may be related to the underlying condition of acute psychosis or could be a behavioral side effect of antipsychotic medication, but they are not symptoms of tardive dyskinesia².
