A 45-year-old man on the neurology floor can understand instructions but is unable to express himself through talking. Which lobe of the brain controls the expression of speech?
Frontal lobe
Occipital lobe
Temporal lobe
Parietal lobe
The Correct Answer is A
Choice A rationale: The frontal lobe, specifically Broca's area located in the dominant hemisphere, is responsible for expressive speech. Damage to this area can result in expressive aphasia or difficulty expressing speech.
Choice B rationale: The occipital lobe primarily processes visual information.
Choice C rationale: The temporal lobe is involved in auditory processing and language comprehension.
Choice D rationale: The parietal lobe is involved in spatial perception, attention, and sensory information processing.

Correct Answer is B
Explanation
Choice A rationale: Metformin does not significantly affect insulin release from the pancreas or glucagon secretion but reduces glucose production by the liver and enhances insulin sensitivity in tissues.
Choice B rationale: Metformin primarily works by reducing glucose production in the liver and improving the body's response to insulin, thereby lowering blood sugar levels.
Choice C rationale: Metformin does not notably slow carbohydrate absorption in the small intestine.
Choice D rationale: Metformin does not directly increase insulin production from the pancreas.
Correct Answer is ["B","C","D","E"]
Explanation
Choice A rationale: A/V fistula assessment is not concerning because a positive bruit and thrill indicate adequate blood flow through the fistula. A dry dressing with scant amount of blood is expected after hemodialysis.
Choice B rationale: The client's low blood pressure could indicate hypotension, which can be critical, especially after hemodialysis. It may contribute to the client's reported dizziness and fatigue.
Choice C rationale: The client’s pulse is irregular which may indicate cardiac arrhythmia. Choice D rationale: Anuria, the absence of urine output, is a significant concern. It could indicate kidney dysfunction or inadequate clearance of waste products, which may have implications following hemodialysis.
Choice E rationale: Oxygen saturation at 92% is relatively low. While the client is alert and oriented, a low oxygen saturation level may indicate potential respiratory compromise or inadequate oxygenation.
Choice F rationale: Temperature is not concerning because it is within normal range.
Choice G rationale: Neurological assessment is not concerning because the client is alert and oriented. The dizziness is likely related to the hypotension and will resolve once the blood pressure is stabilized.
