Flashcard 361: Bell's palsy affects cranial nerve _____

Answer: VII

Flashcard 362: What is the acute management of tension headaches? _____

Answer: Paracetamol, NSAIDs, or aspirin

Flashcard 363: Myasthenia gravis has progressive weakness because _____

Answer: high conc. of ACh are needed to compete with anti-ACh antibodies and yield the same muscle strength. Repetitive use means there is not enough time for ACh to be replenished, thus smaller and smaller amounts of ACh are released and the muscle becomes weaker and weaker

Flashcard 364: Myasthenia gravis can be fatal because of _____

Answer: respiratory compromise

Extra: This life-threatening condition is known as a Myasthenic Crisis, characterized by neuromuscular respiratory failure requiring intubation.

Flashcard 365: Refer Bell's palsy to secondary care if there is incomplete recovery by _____

Answer: 3 months

Flashcard 366: Myasthenia gravis presents with muscle weakness that _____ with muscle use

Answer: worsens

Flashcard 367: What does Myasthenic crisis present with? _____

Answer: Respiratory failure +/- bulbar weakness

Flashcard 368: _____ can be done for initial presentation of Bell's palsy in areas with ticks

Answer: ELISA Borrelia burgdorferi

Flashcard 369: Bell's palsy is often preceded or accompanied by _____ pain.

Answer: retroauricular

Extra: While Bell's palsy involves lower motor neuron facial nerve paralysis, many patients experience pain behind the ear (retroauricular pain). The absence of vesicles helps distinguish it from Ramsay Hunt Syndrome (Herpes Zoster Oticus).

Flashcard 370: Fatigability of muscles in myasthenia gravis can be demonstrated by _____

Answer: repetitive movements (e.g. flap arms) for 30-60 seconds causing weakness
