. 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. Pain in the neck when the patient flexes their head towards the chest. This describes nuchal rigidity, not Kernig sign.
B. Involuntary flexion of the hips and knees when the neck is flexed. This describes Brudzinski sign, not Kernig sign.
C. Photophobia and headache triggered by bright light. These are symptoms of meningitis, but they are not specific to Kernig sign.
D. Pain and resistance when attempting to extend the patient's leg from a flexed position. A positive Kernig sign is when there is pain and resistance to leg extension from a flexed hip and knee position, indicating meningeal irritation.
Correct Answer is B
Explanation
A. Ciprofloxacin, Metronidazole, and Ranitidine: Ciprofloxacin and ranitidine are not recommended for H. pylori treatment. Ciprofloxacin is not typically used, and ranitidine is an H2 blocker, not a proton pump inhibitor.
B. Amoxicillin, Clarithromycin, and Omeprazole: This combination is a standard triple therapy for H. pylori infection. Amoxicillin and clarithromycin are antibiotics, and omeprazole (a proton pump inhibitor) reduces stomach acid to help eradicate the bacteria.
C. Metronidazole, Tetracycline, and Bismuth subsalicylate: This combination is part of quadruple therapy rather than triple therapy. Quadruple therapy is usually reserved for cases resistant to initial treatment.
D. Erythromycin, Amoxicillin, and Famotidine: Erythromycin is not part of standard triple therapy, and famotidine is an H2 blocker, not a proton pump inhibitor.
