Radioactive iodine treatment is the therapy of choice in patients with Graves' disease. The patient should be prepared:

To need short-term thyroid replacement therapy.

To possibly need lifelong thyroid replacement therapy.

To achieve full recovery after treatment.

To receive lifelong iodine treatment.

Answer and Explanation

The Correct Answer is B

Choice A reason: While some patients might need short-term thyroid replacement therapy after radioactive iodine treatment, this is not as common as the need for long-term or lifelong therapy. Radioactive iodine often causes hypothyroidism, which requires ongoing thyroid hormone replacement.

Choice B reason: Radioactive iodine treatment frequently leads to hypothyroidism, where the thyroid gland no longer produces enough thyroid hormone. As a result, patients often require lifelong thyroid hormone replacement therapy to maintain normal thyroid function. This is a common outcome and patients should be prepared for this possibility when undergoing treatment for Graves' disease.

Choice C reason: Although radioactive iodine is effective in treating Graves' disease, it does not guarantee full recovery without the need for further treatment. Most patients will develop hypothyroidism and need thyroid hormone replacement therapy. Complete recovery without any need for ongoing management is uncommon.

Choice D reason: Lifelong iodine treatment is not required after radioactive iodine therapy for Graves' disease. The primary treatment involves administering a specific dose of radioactive iodine to ablate the overactive thyroid tissue. Following this, patients typically need thyroid hormone replacement therapy, not continuous iodine treatment.

Correct Answer is D

Explanation

Choice A reason: Amoxicillin is an antibiotic used to treat bacterial infections and is not relevant to the management of atrial fibrillation. Atrial fibrillation is a cardiac condition, and antibiotics do not play a role in its treatment.

Choice B reason: Reglan (metoclopramide) is a medication used to treat gastrointestinal issues such as gastroparesis and is not used in the management of atrial fibrillation. It does not address the primary concerns associated with atrial fibrillation, such as stroke risk and heart rate control.

Choice C reason: Omeprazole is a proton pump inhibitor used to treat gastroesophageal reflux disease (GERD) and other acid-related conditions. It is not used in the management of atrial fibrillation and does not address the primary concerns associated with the condition.

Choice D reason: Rivaroxaban (Xarelto) is an anticoagulant (blood thinner) commonly prescribed to patients with atrial fibrillation to reduce the risk of stroke. Atrial fibrillation increases the risk of blood clots forming in the heart, which can travel to the brain and cause a stroke. Rivaroxaban helps prevent these clots from forming, thereby reducing the risk of stroke in patients with atrial fibrillation.

A. Pain stimulation above the level of the spinal cord lesion B. Toxic accumulation of free radicals below the level of the injury C. A distended bladder or rectum D. An abnormal vagal response

Correct Answer is C

Explanation

Choice A reason: Pain stimulation above the level of the spinal cord lesion can cause discomfort and an increase in sympathetic activity, but it is not the primary cause of an uncompensated cardiovascular response seen in autonomic dysreflexia. This condition typically results from stimuli below the level of the injury.

Choice B reason: Toxic accumulation of free radicals below the level of the injury can contribute to tissue damage and inflammation but is not the primary cause of the acute cardiovascular responses in autonomic dysreflexia. The condition is primarily triggered by noxious stimuli below the level of the injury.

Choice C reason: A distended bladder or rectum is a common cause of autonomic dysreflexia in patients with spinal cord injuries above the T6 level. This condition involves an exaggerated autonomic response to stimuli below the level of the injury, resulting in severe hypertension, bradycardia, and other cardiovascular symptoms. The distention of the bladder or rectum sends signals that the spinal cord cannot properly process, leading to an uncontrolled sympathetic response.

Choice D reason: An abnormal vagal response typically involves parasympathetic activity and can lead to symptoms such as bradycardia or fainting. However, it is not the primary cause of the sympathetic overactivity and hypertension seen in autonomic dysreflexia. The condition is driven by an imbalance in the autonomic nervous system due to spinal cord injury.
