A client with a diagnosis of multiple sclerosis is scheduled to receive plasmapheresis treatments. A nurse explains to the client's spouse that the purpose of plasmapheresis is to:
infuse lipoproteins to restore the myelin sheath.
remove excess fluid from the blood stream.
restore protein levels in the blood.
remove circulating antibodies from the blood stream.
The Correct Answer is D
A) Infuse lipoproteins to restore the myelin sheath:
Multiple sclerosis (MS) is an autoimmune disease where the immune system attacks the myelin sheath around nerve fibers. Plasmapheresis does not work by infusing lipoproteins to restore the myelin sheath. The treatment's primary goal is to remove harmful substances from the blood that may be contributing to the autoimmune attack, particularly antibodies that target the nervous system, not by restoring the myelin itself.
B) Remove excess fluid from the bloodstream:
Plasmapheresis is a process used to remove certain substances from the plasma, including antibodies and immune complexes that might be exacerbating an autoimmune condition like MS. If the goal were to remove excess fluid, the treatment would be more akin to dialysis or a fluid management procedure, but this is not the case with plasmapheresis.
C) Restore protein levels in the blood:
While plasmapheresis can sometimes lead to a temporary decrease in protein levels due to the removal of plasma, this is not its primary purpose. The primary goal of plasmapheresis in the context of multiple sclerosis is to remove circulating antibodies and other immune-related substances.
D) Remove circulating antibodies from the bloodstream:
Plasmapheresis works by removing circulating antibodies from the bloodstream. In multiple sclerosis, the immune system mistakenly targets the myelin sheath, and plasmapheresis helps to remove the antibodies responsible for this autoimmune response. This can provide temporary relief of symptoms during acute flare-ups of MS by reducing the immune system's attack on the nervous system.

Correct Answer is C
Explanation
A) A corticosteroid such as fluticasone:
While corticosteroids, such as fluticasone, are effective for managing chronic asthma and preventing inflammation over time, they are not the first-line treatment during an acute asthma attack. Corticosteroids are typically used for long-term control and maintenance therapy, not for rapid relief of symptoms in an acute exacerbation. Immediate relief is needed in acute situations, which corticosteroids alone do not provide.
B) A long-acting beta 2 agonist such as salmeterol:
Long-acting beta-2 agonists (LABAs), such as salmeterol, are used for maintenance therapy to prevent asthma attacks and should not be used for the immediate treatment of an acute asthma exacerbation. They take longer to start working, and their role is to provide prolonged bronchodilation over time, not to relieve sudden bronchoconstriction.
C) A short-acting beta 2 agonist such as albuterol:
During an acute asthma attack, the immediate goal is to relieve bronchoconstriction and improve airflow. Short-acting beta-2 agonists like albuterol are the first-line treatment because they quickly relax the smooth muscles of the airways, leading to bronchodilation. Albuterol works within minutes, providing rapid relief from the symptoms of wheezing, shortness of breath, and chest tightness.
D) Methylxanthines such as Theophylline:
Methylxanthines (e.g., theophylline) were once used for asthma management but are no longer considered the first-line treatment for acute exacerbations due to their narrow therapeutic range and the potential for toxicity. While theophylline can provide bronchodilation, its onset of action is slower than that of beta-agonists like albuterol, and it is generally reserved for more chronic management of asthma or severe cases where other medications are not effective.
Correct Answer is D
Explanation
A) Begin initial discharge teaching on home care activities:
While discharge teaching is a vital part of the care process, it is typically an activity assigned to a registered nurse (RN) because it involves comprehensive patient education on topics such as medication management, follow-up care, and recognizing signs of complications. Guillain-Barré syndrome (GBS) often requires intensive care in the acute phase, and the RN is responsible for evaluating the client’s readiness for discharge and ensuring they fully understand the care required at home
B) Begin administration of red blood cells:
Administering blood products, such as red blood cells, requires close monitoring for potential reactions, and it is typically the responsibility of the RN. The RN must assess the client’s baseline status, monitor for transfusion reactions, and adjust care accordingly during the procedure. This task requires a higher level of clinical judgment and nursing knowledge than an LPN.
C) Reassess the client's mobility in the upper extremity:
Reassessing a client’s mobility, especially in a neurological condition like Guillain-Barré syndrome, requires detailed and ongoing assessment to determine changes in the patient’s strength, motor function, and overall neurological status. This activity is a more complex task that requires a registered nurse's clinical expertise.
D) Administration of morphine for pain:
The administration of pain medications, including morphine, can be appropriately assigned to the LPN under the supervision of an RN. The LPN is trained to administer medications and monitor for common side effects such as respiratory depression, especially in clients who may be at risk due to their neurological condition. However, it is essential for the LPN to communicate with the RN and report any significant changes in the client’s condition during pain management.
