Final answer:
Decreased hiring of foreign nurses is not likely the primary factor contributing to the nursing shortage on the nurse manager's unit, considering the shortage is due to supply and demand dynamics, such as retirements and tuition costs, rather than international hiring practices.
Step-by-step explanation:
The nurse manager examining the factors contributing to the nursing shortage on her unit would find that several issues listed could be attributing to the shortage. These include A) Increased age of the RN workforce, which leads to more retirements; B) Increased demand for RNs from competing employers, which can spread the available workforce thin across different institutions; and D) Decreased job satisfaction of the RN workforce, which could lead to higher turnover rates and fewer individuals willing to enter/remain in the profession. However, C) Decreased hiring of foreign nurses is not likely a primary factor in the nursing shortage depicted in this scenario, especially considering the context provided implies that the shortage is because of supply and demand dynamics, including retiring nurses and higher nursing tuition costs, rather than hiring practices related to foreign nurses.
According to the economic model presented, as the demand for nurses increases and the supply shrinks due to retirements and increases in nursing tuition, the supply curve shifts to the left. This leads to higher salaries for nurses at new equilibrium price Pe2, but it does not necessarily affect the hiring of foreign nurses, which is not the focus of the factors detailed in the figures.
