. 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
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 D
Explanation
A. Peripheral Artery Disease (PAD). PAD is a chronic condition related to reduced blood flow in peripheral arteries. It is not directly associated with MI complications.
B. Gastroesophageal Reflux Disease (GERD). GERD involves acid reflux and is not related to post-MI complications.
C. Hypertension. While hypertension is a risk factor for MI, it does not directly explain the symptoms of shortness of breath and irregular heartbeats following an MI.
D. Heart Failure. Heart failure is a common post-MI complication, especially if a significant portion of heart muscle is damaged. Symptoms of shortness of breath and irregular heartbeats could indicate left-sided heart failure, where fluid backs up into the lungs, or right-sided failure, which can lead to systemic congestion.
Correct Answer is ["A","C","D","E"]
Explanation
A. Ensure that the client's urine output is at least 1 ml/kg/hr. Adequate urine output is essential before administering IV potassium to ensure the kidneys are functioning properly and can handle the increased potassium load, preventing hyperkalemia.
B. Ensure potassium infusion is prepared with 5% dextrose solution. While IV potassium can be mixed with normal saline or dextrose solutions, the specific diluent will depend on the clinical scenario. This isn't necessarily a standard requirement, so it may not be appropriate for all situations.
C. Educate the client regarding high-potassium foods. Education on high-potassium foods helps the client maintain potassium levels after treatment, reducing the need for future supplementation.
D. Repeat blood serum potassium levels. Rechecking potassium levels ensures the patient reaches a safe and therapeutic range and helps monitor for signs of overcorrection or continued hypokalemia.
E. Cardiac monitoring during infusion. Cardiac monitoring is critical, as hypokalemia and potassium replacement can affect heart rhythm and lead to arrhythmias.
