Which of the following clients diagnosed with myasthenia gravis would the nurse identify as most at risk for developing a cholinergic crisis? A client who
reports taking an extra dose each day of their anticholinesterase medication.
is experiencing a respiratory infection and is short of breath.
has a family history of autoimmune disorders.
has a past medical history of type 2 diabetes mellitus.
The Correct Answer is A
A. "Reports taking an extra dose each day of their anticholinesterase medication."
This client is at highest risk for developing a cholinergic crisis. A cholinergic crisis occurs when there is overdose or excessive stimulation of acetylcholine receptors due to too much anticholinesterase medication. Symptoms include muscle weakness, respiratory distress, salivation, sweating, and bradycardia. Taking an extra dose of the medication can result in an overdose of acetylcholine, triggering these symptoms. Therefore, this client is at the greatest risk for a cholinergic crisis.
B. "Is experiencing a respiratory infection and is short of breath."
While respiratory infections can worsen symptoms of myasthenia gravis due to increased muscle weakness, this client is not directly at risk for a cholinergic crisis. Respiratory infections can increase the risk of myasthenic crisis, which is a different complication where muscle weakness worsens to the point of respiratory failure. A myasthenic crisis is caused by insufficient anticholinesterase medication or a disease exacerbation, not an overdose.
C. "Has a family history of autoimmune disorders."
A family history of autoimmune disorders may suggest a genetic predisposition to autoimmune diseases, but it does not increase the risk of a cholinergic crisis specifically. The risk of a cholinergic crisis is more directly related to medication management, not family history.
D. "Has a past medical history of type 2 diabetes mellitus."
Type 2 diabetes mellitus does not directly increase the risk of a cholinergic crisis. While diabetes may influence overall health and immune function, it does not have a direct impact on anticholinesterase therapy or the risk of cholinergic crisis in myasthenia gravis.

Correct Answer is C
Explanation
A) Arrange for social service consult for assistance with medication purchase:
While arranging for social service support can be beneficial in ensuring the client has access to necessary medications, this is not directly related to fall prevention at home. Falls in Parkinson's disease are more closely associated with mobility, balance, and environmental factors, which should be the focus of interventions aimed at reducing fall risk. Medication access is important but secondary to safety measures related to physical environment and mobility.
B) Have the client seen by a nursing assistant 3 times a week for hygiene:
While assistance with hygiene can certainly help support the client’s daily needs, the frequency of visits for hygiene care alone does not specifically address fall prevention. Falls are more directly linked to issues such as impaired balance, freezing episodes, and poor mobility—issues that should be addressed through environmental modifications and specific interventions aimed at improving safety during ambulation and transfers.
C) Ensure adequate lighting in areas where the client will ambulate:
Ensuring adequate lighting in areas where the client will ambulate is a critical intervention for fall prevention in individuals with Parkinson's disease. Parkinson's disease often causes balance and coordination problems, and inadequate lighting can increase the risk of tripping or falling, especially at night or in poorly lit areas. Proper lighting helps the client see obstacles and navigate their environment safely. This intervention directly addresses a key factor in fall risk and is an important part of the plan of care.
D) Refer the client to a nutritionist to address dietary measures:
Referral to a nutritionist can be helpful in managing some aspects of Parkinson's disease, particularly for addressing issues like constipation, weight management, or dysphagia. However, dietary measures do not have a direct impact on fall prevention. Fall prevention should focus more on mobility, strength, environmental safety, and managing the symptoms of Parkinson's disease that affect balance and movement.
Correct Answer is D
Explanation
A) Fluid bolus and IV heparin:
A fluid bolus and IV heparin may be used in certain cardiovascular conditions, such as hypotension or in the setting of acute coronary syndrome (ACS) to prevent clot formation. However, in this case, the client is experiencing chest pain with ST segment elevations, a sign of ongoing ischemia, which suggests that the problem may be related to inadequate blood flow to the heart. Fluid boluses could exacerbate the condition if the heart's function is compromised, and IV heparin alone would not address the root cause of the ischemia. Hence, this is not the most appropriate intervention at this time.
B) A medical prescription for a stat chest x-ray:
A chest x-ray would not be immediately indicated in this scenario. The client's symptoms of chest pain, diaphoresis, and ST segment elevations on the ECG are indicative of myocardial ischemia or infarction, not a respiratory or structural lung issue that would be visualized on an x-ray. The priority here is to address the myocardial ischemia, which could be due to a clot or reocclusion in the coronary artery. A stat chest x-ray would not address the underlying cardiac issue, so this is not the best choice.
C) Coronary artery bypass (CABG) surgery if there is no improvement in 12 hours:
While CABG is an option for clients with severe coronary artery disease, it is generally considered when PCI is not successful or when there are multiple blockages that cannot be stented. In this situation, since the client has just undergone PCI and is now experiencing signs of reocclusion (e.g., chest pain, ST segment elevations), a repeat PCI with thrombectomy or angioplasty is more appropriate and urgent. Waiting 12 hours would delay treatment and risk further myocardial damage. CABG would not be the first intervention after a failed PCI within hours of the procedure.
D) Repeat PCI with thrombectomy or angioplasty:
This is the most appropriate intervention. The client's symptoms (chest pain, diaphoresis, and ST segment elevations) are suggestive of reocclusion of the stented artery, a complication that can occur after PCI. Reocclusion can cause further myocardial ischemia and infarction. A repeat PCI with thrombectomy or angioplasty would aim to reopen the blocked artery and restore blood flow to the myocardium, which is the immediate priority in this situation. This intervention can help resolve the ischemia and prevent further damage to the heart muscle.
