A nurse is educating a client recently diagnosed with myasthenia gravis.
Which statement made by the client indicates an understanding of the teaching?
“I will need to take edrophonium to treat the disease.”.
“This disease is a disorder of motor and sensory dysfunction.”.
“This disease doesn’t cause sensory impairment.”.
“I will continue to experience progressive muscle weakness and sensory deficits.”.
The Correct Answer is A
Choice A rationale
Myasthenia gravis is a neuromuscular disorder characterized by weakness and fatigue of voluntary muscles. Edrophonium is a medication that is used in the diagnosis and treatment of myasthenia gravis. It works by inhibiting the breakdown of acetylcholine, a neurotransmitter that transmits signals in the nervous system, thereby improving muscle strength.
Choice B rationale
Myasthenia gravis is not a disorder of motor and sensory dysfunction. It primarily affects the neuromuscular junction, leading to muscle weakness and fatigue. Sensory function is typically not affected in myasthenia gravis.
Choice C rationale
This statement is correct in that myasthenia gravis does not cause sensory impairment. However, it does not indicate an understanding of the disease as a whole, as it does not address the primary symptom of muscle weakness.
Choice D rationale
Myasthenia gravis does cause progressive muscle weakness, but it does not cause sensory deficits. Therefore, this statement indicates a partial understanding of the disease.

Correct Answer is ["4 "]
Explanation
The nurse is preparing to administer 40 mg of furosemide intravenously. The available furosemide is 10 mg/1 mL.
Step 1 is: Calculate the dose in mL using the formula: (Desired dose ÷ Available dose) × Volume.
Step 2 is: Substitute the given values into the formula: (40 mg ÷ 10 mg) × 1 mL = 4 mL. The nurse should administer 4 mL per dose.
Correct Answer is A
Explanation
Choice A rationale
Status epilepticus is a medical emergency characterized by continuous or rapid-fire seizures. Intravenous diazepam is one of the first-line treatments for this condition. It works by enhancing the effect of gamma-aminobutyric acid (GABA), a neurotransmitter that inhibits brain activity, thereby helping to stop the seizure.
Choice B rationale
Oral lorazepam is not typically used to halt a seizure immediately due to its slower onset of action compared to intravenous administration.
Choice C rationale
Oral phenytoin is not typically used to halt a seizure immediately. It is more commonly used for the long-term management of seizures.
Choice D rationale
Intravenous phenobarbital is a second-line treatment for status epilepticus, used when first- line treatments such as diazepam are ineffective.
