As an x-ray tube ages, the inside can become coated with tungsten, which can cause arcing in the tube.

When there is a short circuit inside the tube, usually from the cathode to the tube envelope, tube arcing happens. A brief loss of x-ray output and a localised artefact are the consequences. On transaxial computed tomography (CT) scans, it appears as a near-parallel, equidistant streak pattern, and on coronal and sagittal CT images, as a "horizontal" hypodense band.

The most frequent cause of x-ray tube failure is an inability to effectively disperse the heat produced during routine operation. It is common knowledge that at the anode target, heat accounts for 99% or more of the kinetic energy given to the electron beam.

Therefore, an x-ray tube ages, the inside can become coated with tungsten, which can cause arcing in the tube.

The spouse of a client who was struck by lightning asks the nurse why the areas involved seems so small but the damage is extens

Angelina_Jolie [31]

Electrical burns usually follow an internal path.

<h3>What are the damages caused by a lightning strike on humans?</h3>

While only 10% of those who are struck by lightning die, many of the 90% who do survive have long-term difficulties.

Depending on the sort of lightning hit and the amount of electricity passing through the body, several effects might result from a lightning strike.

Lightning can destroy tissue, leave deep wounds, and result in skin burns. Additionally, the electrical current may result in a sort of scaring called Lichtenberg figures (branching electric discharges). Unusual fractal patterns emerge as a result of blood vessel destruction that occurs when the lightning current passes through the body to describe this sort of scarring.

A lightning strike can halt the heart, leading to cardiac arrest. It may also result in pulmonary edema and arrhythmias.

Brain injury and a variety of neurological disorders may be brought on by lightning strikes. A person may suffer from spinal cord injuries, go into a coma, feel pain, numbness, or weakness in their limbs, or have sleep or memory issues.

A lightning strike could harm the ear and impair hearing. Additionally, it may result in blindness, corneal damage, and vertigo.

A ________ is not typically used in the prehospital setting for oxygen administration.

Evgesh-ka [11]

A partial re-breather mask is not typically used int he prehospital setting for oxygen administration. It is initiated for variety of reasons.

Increased metabolic demand , maintenance of oxygenation while proving anesthesia. This the most common method for home use and provide flow rate of 2 to 6 liter per minute. Allowing the delivery of oxygen while maintaining the patient's ability to utilize their mouth to talk, eat, etc.

The main purpose is treatment for patient with acute respiratory failure and those with chronic lung disease and hypoglycemia. The maintain normal hemoglobin saturation so as facilitate normal oxygen delivery to peripheral tissues.

Click and drag each label into the correct category to indicate whether the scenario would cause crenation (shrinking), hemolysi

LenKa [72]

Question options:

1. Placing a red blood cell in distilled water

2. Placing a red blood cell into an isotonic solution

3. Placing a red blood cell into a hypotonic solution

4. Placing a red blood cell into a hypertonic solution.

5. Placing a red blood cell with a concentration of 0.9% NaCl into a solution of 1.5% NaCl

6. Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.

Answer:

Crenation (shrinking):

-Placing a red blood cell into a hypertonic solution.

-Placing a red blood cell with a concentration of 0.9% NaCl into a solution. of 1.5% NaCl

Hemolysis (swelling):

-Placing a red blood cell in distilled water.

-Placing a red blood cell into a hypotonic solution.

-Placing a red blood cell with an ICF concentration of 0.9% NaCl into a solution with 0.1% NaCl.

No change:

-Placing a red blood cell into an isotonic solution.

Explanation:

Crenation is an osmotic process in which blood cells shrink while placing <u>hypertonic</u> or alkaline solutions. Hemolysis is the destruction of red blood cells in which cells bloat up and may explode while placing in a<u> hypotonic</u> or acidic solution. The blood cells have no change In an <u>isotonic</u> environment because the relative concentrations of solute and water are equal on both sides of the membrane.

Use this scenario to answer the next 2 questions: A 9-year-old child has suddenly collapsed. After confirming that the scene is

navik [9.2K]

Answer: The child is still growing so its immune system is weak. You will need to use a defibrillator on a low frequency because a high frequency could send the child into seizures which the child may not be able to handle. The team should use a defibrillator and they should prepare the child for the hospital. The doctors will need to work quickly so they need to make it as easy as possible because the child could be running out of time.

Explained in the answer section. Hope I helped have a nice day! :)
