Answer:
When the frequency of stimulation of a muscle increases -without it having the opportunity to relax- a process called summation (addition) occurs, promoting an increase in the generation of force in the isolated skeletal muscle.
Explanation:
Summation is a phenomenon that occurs as a consequence of the arrival of successive stimuli that produce the contraction of the skeletal muscle before it achieves its partial or total relaxation, between subsequent stimuli.
<em>When the summation occurs in the muscle, the force generated on it increases its magnitude proportionally to the number of stimuli received, maintaining the muscle contraction in time</em>.
Tetany is the prolonged contraction of a muscle in an abnormal way, by the summation of stimuli received , as some bacterial toxins can produce. The summation can be temporary -when multiple stimuli reach the muscle in a determined time- or spatial, when the amount of stimuli activates a greater amount of motor units.

The nurse should recognize this as Chvostek sign.
<h3>What is
Chvostek sign?</h3>
A clinical indication that someone may have low blood calcium levels is the Chvostek sign (a decreased serum calcium, called hypocalcemia). The aberrant twitching of muscles that are stimulated (innervated) by the facial nerve (also known as Cranial Nerve Seven, or CNVII) is known as the Chvostek sign.
The facial muscles on the same side of the face will occasionally contract when the facial nerve is touched in front of the ear (called ipsilateral facial spasm). Frequently, the muscles that regulate the nose, lips, and brows will spasm.
