. 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 B
Explanation
A. Interferon Gamma Release Assays (IGRAs): IGRAs are useful for detecting TB infection but do not confirm active TB disease. They measure the immune response to TB bacteria but don’t differentiate between latent and active infection.
B. Sputum culture: Sputum culture is the gold standard for confirming active TB because it identifies Mycobacterium tuberculosis bacteria directly, confirming active infection.
C. Tuberculin Skin Test (TST): The TST can indicate TB infection but cannot distinguish between latent and active TB, making it unsuitable as a confirmatory test for active disease.
D. Chest X-ray: A chest X-ray can show signs suggestive of TB but cannot confirm the presence of TB bacteria, so it is not definitive for diagnosing active TB.
Correct Answer is D
Explanation
A. Frequent urination. Frequent urination is not typically associated with Crohn’s disease, which primarily affects the gastrointestinal system.
B. Jaundice. Jaundice is related to liver or biliary system issues and is not a common symptom of Crohn’s disease.
C. Joint pain. While Crohn’s disease may be associated with extraintestinal symptoms, joint pain is not as common as gastrointestinal symptoms during an exacerbation.
D. Abdominal pain and cramping. Abdominal pain and cramping are common symptoms of Crohn’s disease, especially during flare-ups, due to inflammation in the digestive tract.
