Correct Answer: B

Rationale: When a nurse assesses a client with signs of delirium, the priority in determining the cause should be focusing on fluid and electrolyte imbalances. Delirium can often be linked to imbalances in these essential elements, making it crucial to address them promptly. While medication history, psychosocial stressors, and environmental factors can also contribute to delirium, they should be assessed after addressing fluid and electrolyte imbalances due to their immediate impact on cognitive function.

Correct Answer: C

Rationale: The correct action for the nurse to take is to pour warm water over the client's perineum. This intervention helps stimulate urination after catheter removal by providing warmth and promoting relaxation of the muscles. Assessing for bladder distention after 2 hours (Choice A) is not the initial intervention to facilitate voiding. Encouraging the client to try urinating in a sitting position (Choice B) may be uncomfortable if the client is struggling to void. Restricting the client's fluid intake (Choice D) is not appropriate as it can further exacerbate the issue by concentrating the urine.

Correct Answer: B

Rationale: The correct answer is B: 'Identify any reversible causes of delirium.' When managing a client with delirium, it is crucial to first identify and address any reversible factors contributing to the delirium. Administering sedatives (Choice A) may worsen delirium and is not the primary intervention. Increasing environmental stimulation (Choice C) can exacerbate symptoms. Limiting noise and providing a calm environment (Choice D) are beneficial but not as crucial as identifying reversible causes.

Correct Answer: A

Rationale: The correct nursing intervention for a patient receiving anticoagulant therapy is to monitor INR levels and check for signs of bleeding. Monitoring the INR levels helps assess the effectiveness and safety of anticoagulant therapy, while checking for bleeding is essential due to the increased risk associated with anticoagulants. Choice B is incorrect as antiplatelet therapy is not the standard treatment for patients on anticoagulant therapy. Choice C is incorrect as providing additional anticoagulation is not a direct nursing intervention in this scenario. Choice D is incorrect because administering aspirin, an antiplatelet medication, along with anticoagulants can increase the risk of bleeding and is generally avoided.

Correct Answer: C

Rationale: The correct answer is C: Previous violent behavior. This is considered the best predictor of future violent actions as individuals who have a history of violent behavior are more likely to engage in violent acts again. Option A, experiencing delusions, although it can impact behavior, is not as strong of a predictor as past violent behavior. Option B, male gender, is a demographic factor but not as specific or predictive as a history of violence. Option D, a history of being in prison, may indicate past behavior but is not directly linked to future violent actions as a known history of violence.
