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 ["56"]
Explanation
Step 1 is to calculate the total drops per hour. This is done by multiplying the total volume of the solution by the drop factor and then dividing by the total time in minutes. So, (1000 mL × 10 gtt/mL) ÷ 180 min = 55.56 gtt/min. The final calculated answer is approximately 56 gtt/min when rounded to the nearest whole number.
Correct Answer is A
Explanation
Choice A rationale
Triptans, a class of medications commonly used to treat migraines, can cause vasoconstriction, or narrowing of the blood vessels. This can be problematic for patients with angina, a condition characterized by reduced blood flow to the heart. Vasoconstriction could potentially exacerbate this condition, leading to an increased risk of a heart attack. Therefore, the use of triptans may be contraindicated in patients with angina.
Choice B rationale
While asthma is a serious condition that requires careful management, it is not typically considered a contraindication for the use of triptans. Triptans work primarily on the blood vessels in the brain and do not typically interact with the bronchial tubes affected by asthma.
Choice C rationale
Age alone is not typically a contraindication for the use of triptans. However, older adults may have a higher risk of certain health conditions, such as heart disease, which could make the use of triptans more risky. It’s important for healthcare providers to consider the overall health status of the patient, not just their age, when deciding whether to prescribe triptans.
Choice D rationale
While stress can certainly exacerbate migraines, it is not typically a contraindication for the use of triptans. Triptans are designed to relieve the pain and other symptoms of migraines, regardless of their cause. If a patient’s migraines are triggered by stress, it may be beneficial to explore stress management techniques in addition to medication.
