A nurse is preparing to administer dabigatran to a client who has atrial fibrillation. The nurse should explain that the purpose of this medication is which of the following?

Choice A Reason: This is incorrect. Opioids are not indicated for a client who is emerging from a coma, as they can cause respiratory depression, sedation, and confusion. They may also mask the signs of increased intracranial pressure or neurological deterioration.

Choice B Reason: This is incorrect. Darkening the room may not be helpful for a client who is emerging from a coma, as it may increase their disorientation and agitation. The nurse should provide adequate lighting and orient the client to time, place, and person frequently.

Choice C Reason: This is incorrect. Applying restraints may worsen the restlessness and agitation of a client who is emerging from a coma, as they may perceive them as a threat or a restriction. Restraints may also increase the risk of injury, infection, or skin breakdown. The nurse should use restraints only as a last resort and with a physician's order.

Choice D Reason: This is correct. Reducing stimuli is an appropriate intervention for a client who is emerging from a coma, as it can help calm them and prevent sensory overload. The nurse should limit noise, visitors, and unnecessary procedures, and provide a quiet and comfortable environment.

Choice A Reason: This is incorrect because a decreased level of consciousness is a late sign of shock, not an early one. Decreased level of consciousness indicates that the brain is not receiving enough oxygen and blood flow, which can lead to irreversible damage and death.

Choice B Reason: This is correct because increased respiratory rate is an early sign of shock, indicating hypoxia. This finding indicates that the client is experiencing hypoxia, which is a lack of oxygen in the tissues and organs. Hypoxia is a common and early sign of shock, which is a condition where the body's vital organs do not receive enough blood

flow and oxygen due to low blood pressure, low cardiac output, or low blood volume. The client's respiratory rate increases as a compensatory mechanism to increase oxygen intake and delivery.

Choice C Reason: This is incorrect because hypotension is a late sign of shock, not an early one. Hypotension indicates that the blood pressure is too low to maintain adequate perfusion and oxygenation to the vital organs.

Choice D Reason: This is incorrect because anuria is a late sign of shock, not an early one. Anuria indicates that the kidneys are not receiving enough blood flow and oxygen, which can result in acute kidney injury or failure.
