A liter IV bag is running at 50ml/hour. How long will it last?

Answer:

The correct answer is B)Deep petrosal nerve

Explanation:

Postganglionic sympathetic fibers in the nerve of the pterygoid canal originate from the deep petrosal nerve. This corresponds to an internal carotid plexus and is formed by postganglionic fibers of the upper cervical ganglion; transports sympathetic postganglionic fibers directed to the blood vessels.

Final answer:

Medical negligence occurs when a healthcare professional causes harm to a patient by failing to follow established protocols or using known faulty equipment, breaching the principle of nonmaleficence. Liability can fall on healthcare workers, equipment manufacturers, or institutions following flawed procedures.

Explanation:

An example of medical negligence might involve a healthcare professional who fails to adhere to established protocols, resulting in harm to a patient. For instance, if a surgeon performs an operation with knowledge that the equipment they are using is faulty, and this leads to patient injury, that could be construed as negligence. Similarly, if a hospital follows a flawed procedure that is known to be ineffective or dangerous and patients are harmed as a result, this could also be considered medical negligence. Responsibility can be a complex issue, with potential liability falling on healthcare workers, manufacturers of medical equipment, or even the protocols themselves.

Consider the principle of nonmaleficence, which dictates that clinicians should not cause unnecessary harm to patients. If a healthcare provider administratively or clinically harms a patient through a lack of due diligence or outright disregard for safe practices, this would breach the principle of nonmaleficence—a cornerstone of medical ethics.

In contrast, a counter example from a different sector might be a case where a car manufacturer is aware of a brake system defect but proceeds to sell the vehicle regardless. If accidents occur due to the known defect, the manufacturer would be held liable. While this is not directly an example of medical negligence, it illustrates the broader concept of negligence and accountability.

Silver does not react with [tex]HCl[/tex] and the reason behind the fact because, like other reactive metals, silver can not displace hydrogen from [tex]HCl[/tex]silver is below hydrogen in the reactivity series and thus can not displace it.silver does not react with dilute [tex]HCl[/tex] but definitely reacts with concept.

The reaction of silver with hydrochloric acid has no result as this metal does not dissolve in hydrochloric acid because it is covered with a thin layer of silver chloride if you add a free oxygen of the solution in the form of hydrogen peroxide the reaction beads to the oxidation of the silver to silver chlorine.

Final answer:

The specific gravity calculation of a hydrochloric acid solution given its mass (2.79kg) and volume (1L) leads to a specific gravity of 2.79, assuming the solution's density is directly computed from these values.

Explanation:

The question posed was: Five points of diluted hydrochloric acid weighs 2.79kg. Calculate its specific gravity volume of HCl is 1L. However, there seems to be a misunderstanding or misinterpretation in the phrasing of the question as it appears to mix two distinct questions - calculating specific gravity and involving a density-related calculation with given mass and volume, which don't fully align to the standard approach of addressing specific gravity directly.

Specific gravity, in general, is the ratio of the density of a substance to the density of a reference substance; generally, water for liquids, which has a density of 1 g/cm³ (or equivalently 1000 kg/m³). Assuming the question aims to find the specific gravity of this particular 'diluted' hydrochloric acid solution, given its mass and volume, one would first calculate its density by dividing mass by volume, then compare this density to that of water to find its specific gravity. However, there is a lack of clarity regarding the 'five points' mentioned and whether 'diluted' refers to a specific concentration.

Assuming a straightforward calculation where '2.79kg' is the total mass of the hydrochloric acid solution and '1L' is its volume, converting 2.79kg into grams (2790g for compatibility with the common density unit g/mL), and then dividing by the volume in mL (1000mL since 1L=1000mL), the density of the hydrochloric acid solution would be 2.79 g/mL. The specific gravity is then this density divided by the density of water (1 g/mL), yielding a specific gravity of 2.79.
