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 A
Explanation
Choice A rationale: The correct answer is 5 units/hour. To calculate the units of insulin per hour, we need to use the following formula: units of insulin per hour = (units of insulin in the bag / volume of the bag) x infusion rate
Plugging in the given values, we get:
units of insulin per hour = (50 / 100) x 10 units of insulin per hour = 0.5 x 10
units of insulin per hour = 5
Therefore, the client is receiving 5 units of insulin every hour.
Choice B rationale: This is incorrect because it assumes that the infusion rate is equal to the units of insulin per hour, which is not true.
Choice C rationale: This is incorrect because it multiplies the units of insulin in the bag by the infusion rate, which is too high.
Choice D rationale: This is incorrect because it adds the units of insulin in the bag and the infusion rate, which is also too high.
Correct Answer is A
Explanation
Choice A rationale: Considering the mechanism of injury, pain severity, tenderness, swelling, and ecchymosis, there is a high suspicion of a fracture. Immobilization is essential to prevent further injury and reduce pain.
Choice B rationale: Contracture is less likely in this acute injury scenario. Acetaminophen might manage pain, but it doesn't address the risk factor.
Choice C rationale: A sprain is less likely given the severity of pain and the mechanism of injury. Raising the leg doesn't address the risk of a suspected fracture.
Choice D rationale: Dislocation doesn't align with the reported symptoms. Applying heat could potentially worsen inflammation.
