The dental assistant is taking the vital signs of a 62 year-old woman who has severe toothache, Her temperature using the digital thermometer is 101 F. Her blood pressure is 100mm Hg systolic over 70 mm Hg diastolic.Her pulse reading is 75 beats per minute. Which vital signs taken by the dental assistant are not within the normal range? What is the likely cause of the abnormal reading? What characteristic of a digital thermometer should the assistant keep in mind when using it ? How should the dental assistant respond to this information about the patients vital signs?
The normal temperature range is from 97 F to 99 F in adults. Any value obtained which is above 100F is considered as abnormal.
2. The likely cause of the abnormal reading is fever
The symptoms of the severe toothache includes the following:
fever (above 100F) and headachesever pains when pressure is applied to the tooth.swelling of gum surrounding the affected tooth.3. The characteristics the assistance needs to keep in mind while using the digital thermometer is the timing of the thermometer. Digital thermometer reading is taken after 40 seconds of insertion. this is not so with the normal mercury thermometer.
4. The dental assistance needs to notify the dental doctor concerning the abnormal temperature of the old woman. this will help in further diagnosis to be carried out towards the treatment of the severe toothache.

Hope you like it
Thank you ❤️
The statement 'exons are spliced together' is TRUE. The exons are the coding regions of genes.
RNA splicing is a eukaryotic mechanism by which non-coding sequences of genes called 'introns' are removed from the precursor messenger RNA (pre-mRNA), whereas protein-coding sequences called 'exons' are spliced together.These gene coding sequences (exons) are spliced together by a macromolecular complex known as the spliceosome.In consequence, a pre-mRNA is converted into a mature mRNA, which is subsequently used for protein synthesis.In conclusion, the statement 'exons are spliced together' is TRUE.

Removing groundwater for drinking water will stop the water cycle.
True
False
False, removing groundwater for drinking water will not stop the water cycle.
Groundwater, in essence means water present and existing beneath the rock surface. They are stored in the tiny pores of the rock below the earth surface.
Groundwater are the sources of fresh water resources.Rock are drilled with machine to get access to the groundwater.Groundwater are naturally replenished through precipitation, from rivers, lakes and other water bodies.In conclusion, Groundwater form part of the water cycle because after the use of water, its eventually evaporates to the cloud and discharges back into the ground through the rain, rivers, lakes etc.

Which of the following would require an input of energy? Question 5 options: a) diffusion b) filtration c) osmosis d) vesicular transport
Answer:
Which of the following would require an input of energy? Question 5 options: a) diffusion b) filtration c) osmosis d) vesicular transport
Explanation:
vesicular transport
Vesicular transport is the process that would require an input of energy.
Vesicle-mediated transport is the transport process that involves vesicles or vacuoles that form from or fuse with the cell membrane.
Transport vesicles interact indirectly with microtubules through proteins that have the ability to move and are known as dyneins and kinesins. These proteins transform the energy of ATP into movement in a certain direction.
The transport vesicles use microtubules to travel directly and quickly to their destination.
It can be done in two parts:
• Exocytosis: when a vesicle reaches the cell surface, its membrane fuses with the cytoplasmic membrane and expels its contents to the outside.
• Endocytosis: the material that will be incorporated into the cell induces an invagination of the membrane, producing a vesicle that encloses the substance.
Therefore, we can conclude that vesicular transport is the process that would require energy which is obtained from the transformation of ATP.

what does it mean when an emission line of helium from a galaxy is shifted toward red
A. The galaxy contains a small percent of Hydrogen
B. The Galaxy is moving toward the viewer
C. The galaxy is moving away from the viewer
D. The galaxy contains a large percent of hydrogen
Answer:
the answer is the galaxy is moving away from the viewer! lemme know if you need the rest of the answers or anymore help
Explanation:
i took the test :)
When an emission line of helium from a galaxy is shifted toward red, it means that the galaxy is moving away from the viewer. Thus, the correct option is C.
What is Galaxy?The Galaxy may be defined as a tremendous collection of dust, gas, dark matter, and billions of stars and their solar systems, all held together by gravity.
When it is shifted toward red, it describes the displacement of an emission line of helium from a galaxy to longer wavelengths. This alteration is interpreted as a doppler shift.
It depends on the location of any celestial body in a galaxy. The farther from us a star is, the more its light has shifted towards the red end of the visible spectrum.
Therefore, when an emission line of helium from a galaxy is shifted toward red, it means that the galaxy is moving away from the viewer. Thus, the correct option is C.
