"Since the intervention is designed to reduce the number of days that a resident receives antibiotics for bacterial pneumonia, the rate of antibiotic days of therapy per 1,000 resident days is most likely to change if the intervention is effective. Because this effort is not trying to reduce antibiotic starts for bacterial pneumonia, neither the rate of antibiotic starts nor the proportion of antibiotics given for pneumonia may change as a result of the intervention. Although the rate of antibiotic use by class might change if one antibiotic class is most commonly used to treat bacterial pneumonia, this measure wouldn't be the best choice for evaluating the new guideline."

Answer:
Post-operative sensitivity and damage to the pulp
Explanation:
Protective bases are applied to the pulp during the process of dental operations. These protective bases are usually applied in a thickened manner. This helps to prevent post operative sensitivity to substances such as cold sensations. The pulp is also protected as a result of the application of protective bases. 
This makes Protective bases being placed when it is necessary to protect the pulp before the restoration is placed in order to prevent Post-operative sensitivity and damage to the pulp valid.
