Answer:
The correct option is b. myelinated axons from many neurons
Explanation:
White matter is an area which is present in the brain and the spinal cord, that are mainly consists of bundles of myelinated axons, also called tracts. The myelinated axons are the nerve fibres that are surrounded by a lipid-rich substance called myelin.
The presence of the myelin gives the tissue the white colored appearance in contrast to the cerebral cortex which is the grey matter.
Therefore, the myelinated axons from many neurons aggregate together to form the white matter present in the brain and the spinal cord.
Given that,
Age of Mrs Jones = 55 years
Height = 5'6''
Weight = 140 lb = 63.6 kg
The tube feeding ordered for her provides:
1 cal/mL and 40 grams of protein/1000 mL.
It is infusing at a rate of 50 mL/hour for 24 hour.
Suppose, We need to find her protein needs per day
We know that,
According to the DRI, 0.8 gram of protein per kg of body weight is required protein per day.
Thus,
We need to calculate her protein needs per day
Using formula for protein needs per day
Put the value of weight
Hence, 50.88g of protein are needed per day for Mrs jones.
Answer:
The correct answer is E. An elevated level of aldosterone makes both an increase in blood pressure and an increase in stored sodium ion.
Explanation:
Aldosterone, a hormone produced and secreted by the adrenal glands, transmits signals to the kidneys to retain more sodium and eliminate more potassium.
Hyperaldosteronism is a metabolic disorder characterized by an overproduction and secretion of the hormone aldosterone by the adrenal glands, which leads to decreased levels of potassium in the blood plasma and, in many cases to arterial hypertension. Having hyperaldosteronism, the adrenal glands produce too much aldosterone, which causes loss of potassium and sodium retention.
They're measured by gauges. Most butterfly needles range from 18 to 27 gauge. The higher the number is, the smaller or thinner the needle size is. While the size can vary, most needle sizes are 21 to 23 gauge. Hope this helps!
Paresis is a condition in which muscle movement is weakened. Unlike paralysis, individuals with paresis still have some control over the affected muscles.
Paresis occurs due to nerve damage, which can be caused by a variety of factors or conditions.
