A nurse is caring for a client who has myasthenia gravis which has not responded to medication treatments. Which of the following surgeries can treat myasthenia gravis?

A. A vegetarian diet typically does not directly contribute to bronchoconstriction. In fact, a diet rich in fruits and vegetables may provide antioxidants and anti-inflammatory compounds that can be beneficial for respiratory health. Therefore, this option is less likely to be a cause of the client's bronchoconstriction.
B. Rosuvastatin (and other statins) are generally well-tolerated, but some individuals may experience respiratory side effects, including cough or shortness of breath. However, bronchoconstriction as a direct side effect of statins is uncommon and typically not a primary concern unless there is a rare hypersensitivity reaction.
C. Propranolol is a non-selective beta-blocker that can lead to bronchoconstriction, particularly in individuals with asthma or other respiratory conditions. Beta-blockers can block beta-2 receptors in the lungs, potentially causing constriction of the airways and worsening of respiratory symptoms.
D. Acetaminophen (paracetamol) is generally considered safe and does not typically cause bronchoconstriction. It is a non-steroidal anti-inflammatory drug (NSAID) that works differently from medications like beta-blockers, which directly affect the airways.

A. While GBS primarily affects peripheral nerves (nerves outside the brain and spinal cord), it does not typically cause direct degeneration of nerves in the brainstem and spinal cord. Therefore, this option is not correct in the context of respiratory distress in GBS.
B. Pleural effusion caused by immobility: Pleural effusion, an accumulation of fluid in the pleural cavity around the lungs, is not a typical complication of GBS. It is more commonly associated with conditions such as heart failure, pneumonia, or malignancy, rather than directly with GBS.
C. In Guillain-Barre Syndrome, demyelination of nerves affects the transmission of signals from the brain to the muscles, including those responsible for respiration. As a result, respiratory muscles may become weak or paralyzed, leading to shallow breathing and respiratory distress.
D. While respiratory distress can occur in some neurological conditions due to autonomic dysfunction or secondary complications, such as aspiration pneumonia, bronchoconstriction and airway edema are not typical manifestations of GBS itself.
