A nurse is explaining myasthenia gravis to a family. Which of the following points would be included in the explanation? (Select All that Apply.)

A) Eustress:
Eustress refers to positive or beneficial stress that motivates individuals to achieve goals, enhance performance, and promote growth. While eustress plays a role in overall well-being, it does not specifically describe the balance between the sympathetic and parasympathetic nervous systems.

B) Homeostasis:
This is the correct answer. Homeostasis refers to the body's ability to maintain stable internal conditions despite external changes. It involves a dynamic equilibrium that allows various physiological processes to function optimally. The balance between the sympathetic and parasympathetic nervous systems contributes to maintaining homeostasis by regulating functions such as heart rate, blood pressure, digestion, and respiratory rate.

C) Power:
Power typically refers to the ability to exert influence or control over others or situations. While power dynamics may play a role in various aspects of human interaction, it is not specifically related to the balance between the sympathetic and parasympathetic nervous systems.

D) Strength:
Strength refers to the physical or mental capacity to withstand stress or exertion. While strength is important for overall health and resilience, it does not specifically describe the balance between the sympathetic and parasympathetic nervous systems.

A) STAT administration of atropine:
This is the correct answer. Atropine is a cholinergic antagonist that can increase heart rate by blocking the action of acetylcholine on cardiac muscarinic receptors. In cases of severe bradycardia, especially if associated with symptoms such as dizziness, syncope, or hypotension, atropine is often administered to increase heart rate and improve cardiac output. The dose of atropine and frequency of administration depend on the severity of bradycardia and the clinical response.

B) Administration of activated charcoal:
Activated charcoal is used in cases of overdose or poisoning to absorb ingested toxins and prevent their absorption into the bloodstream. However, in this scenario, where the primary concern is bradycardia resulting from cholinesterase inhibitor (donepezil) toxicity, activated charcoal would not be effective in reversing the bradycardic effects of the medication.

C) Hemodialysis:
Hemodialysis is a renal replacement therapy used to remove toxins and waste products from the blood in individuals with kidney failure. While hemodialysis may be indicated in cases of severe drug overdose or poisoning to enhance toxin elimination, it is not typically used as a first-line intervention for bradycardia associated with cholinesterase inhibitor toxicity.

D) Intravenous administration of pseudoephedrine:
Pseudoephedrine is a sympathomimetic drug that acts as a vasoconstrictor and can increase heart rate and blood pressure. While it may be used to treat bradycardia in some cases, such as severe symptomatic bradycardia unresponsive to atropine, it is not the first-line treatment for cholinesterase inhibitor toxicity-induced bradycardia. Atropine is preferred due to its direct antagonism of muscarinic receptors in the heart.
