<h3>Global travel and spread of certain species</h3>
Explanation:
Many pathogenic species of bacteria, virus, and other microbes are more prevalent in developing or tropical countries rather than in developed countries.
When an individual’s immune system is weak they become more susceptible to get infected and become carriers of that particular species.
The species grows, develops, and multiplies in the host’s body and when the traveler travels to his/her home country or any other place he/she can transmit the disease to others and again the species grows in numbers. Higher the rate of spread of infection higher is the increase in species.
Prokaryotic cells do not have membrane bound organelles and eukaryotic cells do have membrane bound organelles
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.
