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 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.

A. Loss of pain temperature, and light touch sensation on the same side as the injury B. Loss of motor function and deep pressure sensation on the opposite side of the injury C. Loss of motor function and position sense on the same side as the injury D. Loss of motor function with preserved pain and temperature sensation in the lower extremities

Correct Answer is C

Explanation

A. Loss of pain, temperature, and light touch sensation on the same side as the injury. In Brown-Sequard syndrome, pain, temperature, and light touch are typically lost on the opposite (contralateral) side of the injury.

B. Loss of motor function and deep pressure sensation on the opposite side of the injury. Motor function and deep pressure sensation loss occur on the same side (ipsilateral) as the injury.

C. Loss of motor function and position sense on the same side as the injury. Brown-Sequard syndrome is a spinal cord hemisection injury leading to loss of motor function and proprioception on the same side as the injury.

D. Loss of motor function with preserved pain and temperature sensation in the lower extremities. Pain and temperature sensations are lost on the opposite side of the injury in Brown-Sequard syndrome, not preserved.
