An infant admitted to the hospital with an acute rotavirus infection is having frequent diarrheal stools. on assessment, the nur
se notes 40 to 60 bowel sounds per minute. the child has poor skin turgor and dry mucous membranes. the nurse determines the infant's dehydration is related to which factor? increased gi motility inability to metabolize nutrients decreased gastric emptying insufficient antidiuretic hormone
The abovementioned infant/patient was observed by the nurse to have 40-60 bowel sounds, poor skin turgor and dry mucous membrane. His/her dehydration is related to increased gastrointestinal (GI) motility as a result of diarrhea from Rotavirus infection. Rotavirus is the most common cause of inflammation of the stomach and intestines (gastroenteritis) leading to diarrhea in infants and children. It is transmitted through fecal-oral route. Fever, watery diarrhea and vomiting are the most common signs and symptoms of the aforementioned virus. Since there is diarrhea, dehydration or even severe dehydration may eventually occur. Symptoms of dehydration includes lethargy, dry and cool skin, absence of tears when crying, dry or sticky mouth, extreme thirst and sunken eyes or sunken fontanel. This infection is self-limiting, has no specific cure and not life threatening. To prevent infection, infants and children should be vaccinated against this virus.
A silent mutation is a mutation in which a single nucleotide base is changed, but that change does not effect the amino acid sequence. A missense mutation is a point mutation in which a single nucleotide is changed, resulting in a codon that codes for a different amino acid.
Answer: While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules.
<span>The graph portrays
predation. The relationship shows that an
increase in the population of zebra
results in a subsequent increase in the lion population, and vice versa. This,
therefore, means that the lion population
is dependent on the zebra population due to an interaction (predation). The lion population
will always be lower than that of the zebra because of the inefficiencies of energy transfer up the trophic levels (exhibited by a
typical energy pyramid). </span>
