Excessive consumption of which of the following is that to cause or worsen hypertension

In class, we discussed a study where monkeys practiced reaching for food pellets by extending/flexing their fingers for a period of 12 days (Nudo et al., 1996).  The researchers examined motor performance before and after this period of training and found that monkeys performed food retrievals better over time. This was an example of the classical neuroplasticity principle of “use it and improve it”. Which of the following is true about what happens to cortical maps after this kind of training?

Ali, a 68-year-old male, is recovering from a total hip arthroplasty performed six weeks ago. He has progressed well in physical therapy and is now practicing ambulation without his cane on a level surface. Ali reports feeling increasingly anxious about falling as he attempts to walk independently. Which of the following instructions would BEST promote an external focus of attention in this scenario, considering Ali’s anxiety and the biomechanics of gait? 

You are working with Jordan, a 35-year-old patient recovering from Guillain-Barre Syndrome. As part of their rehabilitation, you’re designing a motor retraining program to help improve their functional mobility. You are considering different practice schedules to maximize learning and retention of movement skills. Which of the following statements accurately describes massed and distributed practice?

During an outpatient neurorehabilitation session, you evaluate Thomas, a 62-year-old patient who experienced a left middle cerebral artery stroke four months ago. Though he has regained some voluntary movement in his right upper extremity, you observe that he consistently initiates and completes functional tasks—such as opening containers, using utensils, and dressing—with his left arm. When prompted to use his right arm, he appears hesitant and expresses frustration. As a physical therapist, you consider the long-term implications of this behavioral pattern on cortical reorganization and recovery. Which of the following best describes the phenomenon occurring in this case?

Maple Valley Plastics can sell 1,000 defective units “as is” for $2 each or rework them for an additional $2 variable cost per unit and sell for $5 each. Should they rework?

When a segment is eliminated, only avoidable fixed costs are considered relevant.

Prairie Axle Ltd. currently makes 10,000 brackets. Per-unit internal costs: DM $6, DL $5, Var OH $3, Fixed OH $4 (25% avoidable). Supplier price = $15. If bought, freed capacity yields $20,000 additional contribution per year. Best choice and per-unit advantage?

Total cost-plus pricing. Blue Sky Cycles expects to sell 8,000 bikes per year. Total cost per unit = $320. Investment = $2,000,000; desired return = 15%. Compute the target selling price per unit.

Comprehensive incremental decision. Arctic Sportswear Ltd. makes 20,000 jerseys: Sales $50 each; Variable cost $30; Fixed costs $350,000. A competitor offers to supply jerseys for $32 each. If accepted, 40% of fixed costs are avoidable, and the factory can be rented for $60,000 per year. Should Arctic make or buy?
