Answer:
If a vial of morphine has 10 mg/mL, and a dose of 4 mg is required to be administered intravenously, 04 mL must be administered to fulfill the indication.
Explanation:
Morphine is a drug, an opioid derivative, with a potent analgesic and sedative effect. Its use is intended for acute or chronic severe pain, mainly related to cardiovascular disease, cancer or severe trauma.
One vial of morphine vial has a concentration of 10 mg/mL, so if 4 mg is required, a simple calculation must be made:
Morphine: 10 mg ------------ 1 mL
Dose: 4 mg ------------ X
X = (4 x 1)/ 10
X = 4/10
X = 0.4 mL
<em><u>To administer 4 mg of intravenous morphine, 0.4 mL of the injection should be used</u></em>.
Answer:
It varies greatly...
Explanation:
(a) Latitude is one of the main factors that pushes the evolution toward adaption to a environment. For example, at higher latitude, the diversity is a little low than on lower or average latitude due to the availability of resources that are easily available on ground level relatively.
(b) As we goo deep in ocean, the diversity of life increases as seen in graph but then after a peak point declines rapidly. This is because at normal depth life thrive in normal conditions of temperature and pressure but deep down low, the pressure of water is so intense that it can even crush lead. So, the little amount of organisms that are living in those depths are highly evolved to that intense environment...
(c) Pollution puts a opposite effect on diversity either it is air, water or ground type of pollution. Marine biodiversity take a great loss from chemicals waste as well as the ground animals in which the viable environment gets completely destroyed. This is the main cause of extinction of various animal and plants species.
Answer:
basic unit of mass
Explanation:
A kilogram is very nearly equal (it was originally intended to be exactly equal) to the mass of 1,000 cubic cm of water. The pound is defined as equal to 0.45359237 kg, exactly.
<u>Answer:</u>
<em>Cluster of neurons cell bodies in the thalamus is called nucleus.
</em>
<u>Explanation:</u>
Nuclei are present all various points in the central nervous system and are connected to each other through various tracts. Thalamus is a part of the brain and contains different type of nuclei.
<em>They are relay nuclei, association thalami nuclei and non-specific nuclei.
</em>
Association thalami nuclei receives the highest input from the cerebral cortex. Non-specific nuclei plays a significant role in regulating sleep and wake cycles.
Red and blue, only the red and blue ends of the visible part of the electromagnetic spectrum are used by plants in photosynthesis.
