A nurse is caring for a patient with atrial fibrillation. In addition to an antidysrhythmic, what medication does the nurse plan to administer?
Warfarin
Atropine
Dobutamine
Magnesium sulfate
The Correct Answer is A
Choice A reason: Warfarin is an anticoagulant commonly used in patients with atrial fibrillation to prevent the formation of blood clots. Atrial fibrillation increases the risk of stroke due to the potential for blood clots forming in the heart and traveling to the brain. Warfarin helps reduce this risk by thinning the blood and preventing clot formation.
Choice B reason: Atropine is used to treat bradycardia (slow heart rate) and is not typically used for patients with atrial fibrillation. Its primary function is to increase the heart rate by blocking the vagus nerve's effects on the heart. In the context of atrial fibrillation, anticoagulation is more crucial to prevent complications like stroke.
Choice C reason: Dobutamine is an inotropic agent used to increase cardiac output in patients with heart failure or cardiogenic shock. It is not used for managing atrial fibrillation. Dobutamine works by stimulating the heart to pump more effectively but does not address the risks associated with atrial fibrillation, such as blood clot formation.
Choice D reason: Magnesium sulfate is used to treat various conditions, including torsades de pointes (a type of abnormal heart rhythm) and severe asthma attacks. It is not typically used for atrial fibrillation. The focus in atrial fibrillation management is on controlling the heart rate or rhythm and preventing thromboembolic complications with anticoagulation therapy.

Correct Answer is C
Explanation
Choice A reason: Albumin is a plasma expander and is typically used to restore blood volume in cases of shock, burns, or trauma. However, it is not specifically indicated for managing spinal shock. Albumin helps in maintaining osmotic pressure and fluid balance but does not directly address the underlying pathophysiology of spinal shock.
Choice B reason: Nitroprusside is a potent vasodilator used to manage hypertensive crises. It works by rapidly reducing blood pressure through vasodilation. In the context of spinal shock, where hypotension is a concern, administering nitroprusside would be inappropriate as it could exacerbate the hypotensive state and worsen the patient's condition.
Choice C reason: Dexamethasone, a corticosteroid, is used to reduce inflammation and edema around the spinal cord following an injury. The anti-inflammatory properties of dexamethasone help to mitigate secondary damage caused by swelling and pressure on the spinal cord tissue. It is commonly administered in cases of acute spinal cord injuries to improve neurological outcomes and manage symptoms of spinal shock.
Choice D reason: Furosemide is a diuretic used to manage fluid overload and edema. It works by increasing urine output, which can help reduce fluid retention in various conditions, such as heart failure and renal impairment. However, it is not specifically indicated for the management of spinal shock and does not address the underlying causes of spinal cord injury-related inflammation and edema.
Correct Answer is B
Explanation
Choice A reason: Suctioning every 2 hours is not appropriate for a patient with increased intracranial pressure (ICP). Suctioning can increase ICP due to the stress and stimulation it causes. It should only be performed when absolutely necessary and with proper precautions to minimize ICP spikes.
Choice B reason: Providing rest periods between nursing procedures is the correct measure. This helps minimize stimulation and stress, which can increase ICP. Rest periods allow the patient to stabilize and reduce the risk of further increasing the pressure within the skull.
Choice C reason: Encouraging active range of motion exercises is not suitable for a patient with increased ICP. Physical activity can exacerbate the condition by increasing intracranial pressure. The focus should be on minimizing activity and stress to prevent further elevation of ICP.
Choice D reason: Assigning the patient to a semiprivate room near the nurse's station is not the best approach. Patients with increased ICP require a quiet and calm environment to help manage their condition. A semiprivate room near the nurse's station may expose the patient to more noise and activity, which could increase ICP.
