Answer:
I would say that the answer to the question: Blood viscosity is highly variable in healthy individuals under resting conditions, would be, B: False.
Explanation:
Blood viscosity is the density present in the blood due to its charge of cells (red blood cells, white blood cells, and platelets) in relation to the amount of serum, or water, in the mix. This viscosity then, is highly dependent on hematocrit, or the count mostly of red blood cells. There are conditions that can make hematocrit counts rise severely, and make blood more viscous, like extreme temperature conditions, dehydration, or an illness, as well as blood loss. However, in general, under normal conditions, in a healthy person, under resting situations, the hematocrit tends to remain normally at 40%, and blood viscosity remains at a normal level. If hematocrit changes, rises, or falls, then viscosity will also change, but for this to happen, the person must not be meeting resting, and normal, conditions.
Bridges can be made of gold or porcelain and are connected to what?
a. Gingiva
b. Bone
c. Abutment teeth
d. They need no connection
Answer:
The correct answer is option C. abutment teeth.
Explanation:
Abutment teeth are a term that is used for teeth that are present or anchored on either side of the teeth that can be attached or removable prosthetic denture or teeth bridges.
Bridges function as a framework and can be made up of metal such as gold or porcelain that is attached to the backs of abutment teeth. In simple words, an abutment is a site in the mouth that is used to anchor a fake tooth.
Thus, the correct answer is option C. abutment teeth.
The noninvasive treatment to break up kidney stones, called _____________ involves shock waves.
Answer: lithotripsy
Explanation:
Kidney stones can be define as one of the urogenital disorders. There is no reason for the formation of kidney stones. Typically the adults which are over the age of 40 and males are more susceptible to the develop kidney stones.
The lithotripsy is a non-invasive technique which utilizes the shock waves so as to break the stones present in the kidneys into small pieces so that they can be easily pass through the body by urine.
In a healthy adult, blood pressure at the union of the vena cavae and right atrium is about 80 mm Hg.
a. True
b. False
Final answer:
The statement regarding blood pressure at the union of the vena cavae and right atrium being about 80 mm Hg is false; this value is much lower and close to 0 mm Hg, while the normal systemic arterial blood pressure should be around 120/80 mm Hg.
Explanation:
The statement that in a healthy adult, blood pressure at the union of the vena cavae and right atrium is about 80 mm Hg is false. The pressure at this junction, known as the central venous pressure, is much lower than systemic arterial blood pressure and is usually close to 0 mm Hg in a healthy individual. The normal blood pressure for a healthy adult is typically stated as 120/80 mm Hg, where 120 mm Hg represents the systolic pressure and 80 mm Hg represents the diastolic pressure. The blood pressure values mentioned in the question are reminiscent of the systemic arterial pressure, not the pressure at the vena cavae and right atrium. Moreover, it is the systolic and diastolic pressures that are measured when a healthcare professional checks arterial blood pressure, not venous pressure.
An individual who meets the threshold criteria for the risk factor of prediabetes should be considered to have a metabolic disease.
a. True
b. False
Answer:
b. False
Explanation:
Pre-diabetes is the clinical situation that precedes the diagnosis of type 2 diabetes. At this point, the body begins to show signs, mainly through blood tests, that sugar (blood glucose) levels are starting to get high, and insulin levels too. Pre-diabetes is well known for its state of insulin resistance, when the pancreas starts producing too much insulin in an attempt to control sugar levels. The patient who has pre-diabetes cannot be diagnosed with the disease, because being pre-diabetic does not mean being diabetic, but it does mean that there is a great chance that in the future (perhaps near) this patient will develop the metabolic disease.
