A patient with myasthenia gravis is admitted to the hospital with signs of a myasthenic crisis. Which of the following symptoms should the nurses expect to observe?

Increased pulse, respirations and blood pressure with dysphagia and respiratory distress

Hypotension, diarrhea and increased salivation

Bradycardia and hypothermia

Tachypnea and hyperactive deep tendon reflexes

Answer and Explanation

The Correct Answer is A

A. Increased pulse, respirations and blood pressure with dysphagia and respiratory distress. A myasthenic crisis is characterized by severe muscle weakness that can lead to respiratory failure, dysphagia, and increased vital signs due to the stress of respiratory distress.

B. Hypotension, diarrhea, and increased salivation. These symptoms are more indicative of a cholinergic crisis, which is due to excess acetylcholine.

C. Bradycardia and hypothermia. Bradycardia and hypothermia are not characteristic signs of a myasthenic crisis.

D. Tachypnea and hyperactive deep tendon reflexes. While tachypnea can occur in respiratory distress, hyperactive reflexes are not typical in myasthenic crisis, as it involves neuromuscular weakness.

Correct Answer is C

Explanation

A. "I should monitor my temperature regularly and report any fevers to my healthcare provider." This statement shows correct understanding. Fever may indicate worsening infection or complications, so it’s important to monitor and report any fevers.

B. "I need to inform my healthcare provider about any new symptoms, such as shortness of breath or chest pain." This statement shows understanding. New symptoms, especially respiratory or cardiac, could signify complications, and should be reported.

C. "I can stop taking my antibiotics once I feel better." This indicates a need for further teaching. Completing the full course of antibiotics is crucial to ensure the infection is completely eradicated, even if symptoms improve.

D. "I will need to take antibiotics before dental procedures." Patients with infective endocarditis often require prophylactic antibiotics before dental procedures to prevent bacterial entry into the bloodstream.

A. Administer high-calorie diet to prevent weight loss. B. Reduce sodium intake to help manage fluid retention. C. Encourage complete bed rest to reduce cardiac workload. D. Increase fluid intake to maintain hydration.

Correct Answer is B

Explanation

A. Administer high-calorie diet to prevent weight loss. While adequate nutrition is important, a high-calorie diet is not the primary priority in managing heart failure. Sodium and fluid management are usually more crucial to control fluid overload.

B. Reduce sodium intake to help manage fluid retention. Reducing sodium intake is a priority in heart failure management as it helps prevent fluid retention, which reduces workload on the heart and decreases symptoms of fluid overload.

C. Encourage complete bed rest to reduce cardiac workload. Complete bed rest is not recommended as it can lead to deconditioning and increased risk of blood clots. Activity should be balanced according to the patient’s tolerance.

D. Increase fluid intake to maintain hydration. In heart failure, increasing fluid intake could worsen fluid overload. Fluid restriction may be necessary to prevent excess fluid retention.
