The clinic nurse is caring for a client with a recent diagnosis of myasthenia gravis. The client has begun treatment with pyridostigmine bromide. What change in status would most clearly suggest a therapeutic benefit of this medication?

Improved Gl function

improved cognition

Decreased pain

increased muscle strength

Answer and Explanation

The Correct Answer is D

A. Improved GI function: While pyridostigmine can influence parasympathetic activity and potentially affect GI motility, the primary goal of the medication in myasthenia gravis is not GI improvement. Any GI effects are secondary and not the indicator of therapeutic success.

B. Improved cognition: Pyridostigmine does not act on cognitive pathways and has no significant impact on brain function. Cognitive changes are not characteristic of myasthenia gravis, and improved cognition would not be a reliable sign of medication effectiveness.

C. Decreased pain: Pain is not a hallmark symptom of myasthenia gravis. Pyridostigmine is not an analgesic and does not directly alleviate pain. The presence or absence of pain does not reflect the medication’s therapeutic impact in this condition.

D. Increased muscle strength: Myasthenia gravis is characterized by fluctuating muscle weakness. Pyridostigmine enhances communication at the neuromuscular junction, leading to improved strength. A noticeable increase in voluntary muscle function is the clearest sign the medication is working as intended.

Correct Answer is A

Explanation

A. Oral Cholinergics: Cholinergic medications, such as pilocarpine, help reduce intraocular pressure by increasing the outflow of aqueous humor. They are commonly used in the treatment of glaucoma to protect against optic nerve damage and preserve vision.

B. Loop diuretics: Loop diuretics like furosemide are used to manage fluid overload in conditions like heart failure or hypertension, not glaucoma. They do not influence intraocular pressure or aqueous humor dynamics.

C. Potassium-sparing diuretics: Potassium-sparing diuretics affect renal excretion of electrolytes and fluids, not intraocular pressure. They have no direct role in glaucoma treatment and are not prescribed for this condition.

D. Antibiotics: Antibiotics are prescribed to treat or prevent infection, particularly in conjunctivitis or post-surgical eye care. They are not used to manage chronic conditions like glaucoma unless there is a concurrent infection.

A. Carpel tunnel syndrome B. Tendonitis C. Impingement syndrome D. Dupuytren contracture

Correct Answer is A

Explanation

A. Carpal tunnel syndrome: Carpal tunnel syndrome involves compression of the median nerve in the wrist, often causing pain, numbness, and tingling in the thumb, index, and middle fingers. Repetitive wrist movements, like those in mechanical work, commonly contribute to this condition and may worsen symptoms during activity.

B. Tendonitis: Tendonitis is inflammation of a tendon and typically presents with localized joint pain, swelling, and tenderness. It does not usually cause numbness or affect specific fingers in the same distribution seen with median nerve compression.

C. Impingement syndrome: Impingement syndrome generally refers to a condition affecting the shoulder joint, often involving pain with overhead activities. It would not account for numbness and pain specifically limited to the thumb and first two fingers.

D. Dupuytren contracture: Dupuytren contracture results in progressive thickening of the palmar fascia, leading to finger flexion contractures, especially of the ring and little fingers. It does not cause numbness or affect the thumb, index, or middle fingers in early stages.
