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

Answer and Explanation

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 A

Explanation

Choice A reason: Explaining that diarrhea is expected and that it is how the body gets rid of ammonia is accurate. Lactulose is often prescribed for patients with hepatic encephalopathy, and its purpose is to reduce blood ammonia levels by promoting bowel movements. Diarrhea is a common and anticipated side effect, as it helps eliminate ammonia from the body.

Choice B reason: Recommending Kaopectate for loose stools is not appropriate in this context. Kaopectate is an anti-diarrheal medication, and using it would counteract the effect of lactulose, which aims to promote bowel movements to reduce ammonia levels.

Choice C reason: Instructing the patient to stop taking the medication until stools firm up is incorrect. Lactulose should be continued as prescribed to maintain its therapeutic effect of reducing blood ammonia levels. Stopping the medication would negate its benefits and potentially worsen the patient's condition.

Choice D reason: Suggesting to send a stool specimen to the laboratory is unnecessary in this scenario. Diarrhea is an expected side effect of lactulose, and there is no indication that a stool specimen needs to be analyzed unless there are signs of infection or other complications.

A. Respiratory compromise. B. Stress ulcer. C. Paralytic ileus. D. Spinal shock.

Correct Answer is A

Explanation

Choice A reason: Respiratory compromise is the greatest risk for a client with a C4 spinal cord injury. The C4 spinal level is critical for the function of the diaphragm, which is the main muscle responsible for breathing. Injury at this level can impair diaphragmatic function, leading to difficulty in breathing or even respiratory failure. Immediate and continuous monitoring of respiratory status is essential for these patients to ensure adequate ventilation and oxygenation.

Choice B reason: Stress ulcers can develop in patients with spinal cord injuries due to the stress response and immobility. However, they are not the highest immediate risk compared to respiratory compromise, which can be life-threatening if not promptly addressed.

Choice C reason: Paralytic ileus, a condition where the intestines stop moving, can occur in spinal cord injury patients due to disruption of the nervous system control of the gut. While it is a significant concern, it is not as immediately life-threatening as respiratory compromise.

Choice D reason: Spinal shock is a condition that can occur after a spinal cord injury, leading to temporary loss of reflexes below the level of the injury. While it is an important condition to recognize and manage, the most urgent risk for a patient with a C4 injury is respiratory compromise due to the potential impact on breathing.
