Answer: Refractory period of the cardiac action potential
Explanation:
Unlike the skeletal muscle which can be reactivated before it reaches a contraction, cardiac muscle must wait before it is almost completely relaxed to be activated again (because of its long refractory period), so one cannot make an increase in strength of contraction with a high frequency of stimulations.

Explanation:
OSHA was born from the Occupational Safety and Health Act, which was signed into law by President Richard Nixon in 1970. Ever since then, this federal organization has established the legal framework under which companies, corporations, institutions and organizations where people are employed, must work regarding the safety and health of their employees. In the case of hospitals, given the known hazards to health that these places of work pose for employees, OSHA has established additional sets of regulations that must be met, especially to prevent exposure to pathogenic entities. Among the requirements demanded by OSHA from hospitals, we find: 1. the placement of puncture-proof containers for the correct disposal of needles, and 2. the establishment of follow-up procedures and protocols for workers who have become exposed to either a blood splash, or a needle stick. They have not established that there should be hepatitis B shots available for hospital employees. This is why the answer is C.
