The nurse must document this occurrence by acceleration is a sudden advancement beyond the starting point of 15 beats per minute for 15 seconds and if the acceleration continues for more than 10 minutes it is considered a change in starting point rate. A tachycardic fetal heart rate is beyond 160 beats per minute. A normal fetal heart rate or as called as FHR usually ranges from 120 to 160 beats per minute in the in utero period. It is measurable sonographically from around 6 weeks and the normal range differs throughout development in which increasing to about 170 beats per minute at 10 weeks and decreasing from then to around 130 beats per minute at term.
A point mutation is a kind of mutation in RNA or DNA, that is, the genetic substance of the cell, in which one single nucleotide base is deleted, added, or changed. It is a wide term applied for the kind of mutation in which only one nucleotide in the arrangement of the gene is substituted by the other nucleotide.
The point mutations most usually include the substitution of one base with another that alters the complementary base as well in DNA. The term point mutation also involves deletions or insertions of a single pair of the base.
A strain is a low-level taxonomic rank used at the
intraspecific level (within a species). While the majority of the members of the same species have very high similarity in their genomes, there occasionally is a proportion of the species that has a little different genome from the popular species group. This variability results in different strains on the species.
A harmless Staphylococcus
aureus may have a muted virulence gene. However, either due to mutation of the
gene or recombination with the harmful strain, a harmless Staphylococcus
aureus could easily turn virulent (harmful).
