. 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. Warfarin. Warfarin (Coumadin) is an anticoagulant used to prevent blood clots, but it typically requires several days to achieve a therapeutic effect and needs close monitoring of INR (International Normalized Ratio) levels. While it can be used for long-term prevention of DVT, it's not the immediate choice for post-operative prophylaxis.
B. Alteplase (tPA). Alteplase is a thrombolytic agent, used to break down existing clots, not prevent their formation. It is typically used in emergency situations, such as for treating ischemic stroke.
C. Clopidogrel. Clopidogrel is an antiplatelet agent, often used to prevent arterial clots, not DVTs. It is more commonly used in conditions like stroke and heart disease.
D. Enoxaparin. Enoxaparin, a low molecular weight heparin, is commonly used to prevent DVT after surgery by inhibiting specific clotting factors. It’s frequently prescribed for DVT prevention in orthopedic surgery patients.
Correct Answer is C
Explanation
A. Frequent urination: Frequent urination is not associated with osteomyelitis, a bone infection.
B. Increased range of motion: Osteomyelitis typically causes pain and restricted movement, not increased range of motion.
C. Localized bone pain and tenderness: Osteomyelitis commonly presents with localized bone pain, tenderness, and possibly swelling due to infection.
D. Hyperpigmentation of the skin: Hyperpigmentation is not a typical sign of osteomyelitis.
