The nurse has provided discharge teaching to a client prescribed nitroglycerin SL. Which statement, made by the client, indicates that the teaching has been effective? I will:

hoice A reason: Preparing for endotracheal intubation and ventilatory support is not the action that the nurse should take for a client with thyroid storm. This intervention is indicated for clients with respiratory failure or impending airway obstruction, which are not the case for this client.

Choice B reason: Providing continuous sedation for pain relief is not the action that the nurse should take for a client with thyroid storm. This intervention may worsen the client's condition by suppressing the respiratory drive and lowering the blood pressure. The nurse should administer antithyroid medications, beta blockers, and corticosteroids as prescribed to reduce the thyroid hormone levels and the associated symptoms.

Choice C reason: Initiating cardiac monitoring and assessing for reflex bradycardia is not the action that the nurse should take for a client with thyroid storm. This intervention is indicated for clients with hyperkalemia or digoxin toxicity, which are not the case for this client. The nurse should monitor the client's heart rate and rhythm, but not expect a reflex bradycardia, which is a paradoxical slowing of the heart rate in response to a rapid rise in blood pressure.

Choice D reason: Maintaining IV fluid infusion and assessing adequacy of hydration is the action that the nurse should take for a client with thyroid storm. This intervention is indicated for clients with thyroid storm, as they are at risk of dehydration and electrolyte imbalance due to increased metabolic rate, fever, sweating, vomiting, and diarrhea. The nurse should administer isotonic fluids, such as normal saline, and monitor the client's fluid intake and output, urine specific gravity, and serum electrolytes.

Choice A reason: Tinnitus is not a common or serious side effect of digoxin, a drug that strengthens the contraction of the heart and regulates the heart rhythm. ¹ Tinnitus is a ringing or buzzing sound in the ears that can be caused by many factors, such as ear infections, loud noises, or medications. ² However, digoxin is not known to cause tinnitus, and it is not a reason to call the healthcare provider.

Choice B reason: Constipation is not a common or serious side effect of digoxin. Digoxin does not affect the bowel function, and it is not a reason to call the healthcare provider. Constipation can be caused by many factors, such as dehydration, lack of fiber, or medications. ³ The client should drink plenty of fluids, eat high-fiber foods, and exercise regularly to prevent or relieve constipation.

Choice C reason: Visual disturbances are a common and serious side effect of digoxin, and they are a reason to call the healthcare provider. Digoxin can cause changes in vision, such as blurred vision, yellow or green halos around objects, or seeing spots or flashes. ¹ These are signs of digoxin toxicity, which is a potentially life-threatening condition that occurs when the level of digoxin in the blood is too high. The client should report any visual disturbances to the healthcare provider as soon as possible.

Choice D reason: Vertigo is not a common or serious side effect of digoxin. Vertigo is a sensation of spinning or losing balance that can be caused by many factors, such as inner ear problems, head injuries, or medications. However, digoxin is not known to cause vertigo, and it is not a reason to call the healthcare provider.
