The nurse is preparing to care for a patient who has myasthenia gravis.
The nurse will be alert to symptoms affecting which body system in the patient?
Gastrointestinal (GI) and lower extremity muscles.
Central nervous system (CNS), memory, and cognition.
Respiratory and facial muscles.
Cardiovascular system and postural muscles.
The Correct Answer is C
Choice A rationale
Myasthenia gravis primarily affects voluntary muscles, especially those involved in breathing and facial movements. Gastrointestinal (GI) and lower extremity muscles are generally not the main muscles affected by this condition. It is an autoimmune disorder that impacts the neuromuscular junction, where nerves communicate with muscles, leading to muscle weakness and fatigue.
Choice B rationale
The central nervous system (CNS), memory, and cognition are not typically impacted by myasthenia gravis. This disorder primarily involves peripheral nervous system issues that affect voluntary muscle control rather than cognitive functions. Myasthenia gravis does not cause alterations in memory or cognition as seen with central nervous system disorders like Alzheimer's disease.
Choice C rationale
Myasthenia gravis notably affects respiratory and facial muscles. The autoimmune attack on acetylcholine receptors leads to muscle weakness, particularly in muscles controlling eye movements, facial expressions, and breathing. Patients may experience difficulty breathing, swallowing, and maintaining an open airway due to this muscle weakness.
Choice D rationale
The cardiovascular system and postural muscles are not commonly affected by myasthenia gravis. This condition involves the neuromuscular junction and leads to fatigue in voluntary muscles, primarily those involved in eye movement, facial expressions, and respiration. Cardiovascular symptoms are not a direct consequence of myasthenia gravis.

Correct Answer is A
Explanation
Choice A rationale
This choice is correct. The side effects of paroxetine, including headaches, nervousness, and poor appetite, are common during the initial weeks of treatment and often decrease over time as the patient’s body adjusts to the medication. Reassuring the patient helps them continue the treatment without undue anxiety about these side effects, which are typically transient and manageable.
Choice B rationale
This choice is incorrect. Abruptly stopping paroxetine without consulting a healthcare provider is not recommended because it can lead to withdrawal symptoms and a possible relapse of depression or anxiety. The patient should only discontinue the medication under the guidance of a healthcare provider, who may suggest a gradual tapering off process to minimize withdrawal symptoms.
Choice C rationale
This choice is partially correct. Taking paroxetine with food can help mitigate some gastrointestinal side effects, such as nausea. However, it does not directly address headaches, nervousness, or poor appetite. Although taking the medication with food is a useful tip, it is not the most comprehensive advice for this particular situation.
Choice D rationale
This choice is incorrect. While adjusting the dose may be an option, it is premature to suggest this after only two weeks of treatment. The patient’s body may still be adjusting to the medication, and many side effects diminish with time. The decision to change the dosage should be made by the healthcare provider based on a thorough evaluation of the patient’s response to the treatment.
Correct Answer is A
Explanation
Choice A rationale
Cough and sneeze reflexes indeed serve to clear the airway of irritants and secretions.
Choice B rationale
Stating false would be incorrect as these reflexes are protective mechanisms for the respiratory system. .
