Question 1 of 5
A female patient who had a stroke 24 hours ago has expressive aphasia. What is an appropriate nursing intervention to help the patient communicate?
Correct Answer: A
Rationale: Expressive aphasia impairs speech output; yes/no questions aid communication. B/C are therapy, D undermines autonomy. [Level: Application]

Correct Answer: B
Rationale: Excess K+ efflux causes temporary hyperpolarization below resting potential. [Level: Knowledge]
