A nurse is caring for a client who has myasthenia gravis. The nurse should recognize that this disease is caused by which of the following types of hypersensitivities?

The nurse should check the client's vital signs first because nausea and weakness are signs of digoxin toxicity, which can also cause bradycardia, hypotension, and arrhythmias. The nurse should also assess the client's serum digoxin level, potassium level, and electrocardiogram.

Request a dietitian consult is wrong because it is not the priority action and it does not address the possible cause of the client's symptoms. A dietitian consult may be helpful to provide nutritional education and guidance, but only after ruling out or treating digoxin toxicity.

Suggest that the client rests before eating the meal is wrong because it is not the priority action and it may delay the diagnosis and treatment of digoxin toxicity. The nurse should not assume that the client's symptoms are due to fatigue or lack of appetite, but rather investigate for any underlying problems.

Request an order for an antiemetic is wrong because it is not the priority action and it may mask the symptoms of digoxin toxicity. The nurse should not administer any medications that could interact with digoxin or worsen its effects, but rather notify the provider and follow the protocol for digoxin toxicity management.

a.This is appropriate as regular, moderate exercise can help improve cardiovascular health and functional capacity in clients with heart failure. It is essential to discuss appropriate types and levels of exercise based on the individual’s condition.

b.This is incorrect because clients should be instructed to notify the provider if they gain 1 kg (2.2 lbs) in one day or 2 kg (4.4 lbs) in one week. A weight gain of 0.5 kg is not typically a threshold for concern.

c. Take diuretics early in the morning and before bedtime is wrong because it may disrupt the client's sleep patern and cause nocturia. The nurse should advise the client to take diuretics early in the morning and avoid taking them in the evening or at night, unless prescribed otherwise.

d. Take naproxen for generalized discomfort is wrong because naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that can worsen heart failure by causing sodium and water retention, increasing blood pressure, and reducing the effectiveness of diuretics and other heart failure medications. The nurse should advise the client to avoid NSAIDs and use acetaminophen or other alternatives for pain relief, as prescribed by the provider.
