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 nursing intervention that should be a priority when an older adult client gets diagnosed with end-stage renal disease (ESRD) and has fluid volume excess is: assessing the client's lung sounds.
ESRD is a chronic kidney disease resulting in kidney failure. This is a gradual loss of the functioning of kidney that cannot be restored. The only solution to this disease is long-term dialysis on a regular basis or kidney transplant.
Lung sounds are of different types depending upon the condition of a person lungs. Listening to this sound, also called auscultation is necessary to assess the right medical condition. The sounds related to fluid overload in lungs are grunting, gurgling, or wheezing.

systole answer is number 1 and diastole is no 2
As population continues to grow and demands for resources increase, understanding the nexus of Food-Energy-Water Systems (FEWS) is vital to ensure the reliability and equity of access to these crucial resources. FEWS are tightly intertwined and characterized by complex tradeoffs that are not yet well understood. Understanding the demands for and tradeoffs amongst FEW resources is particularly challenging in semi-arid regions, where increasing population trends are likely to continue, and water shortage poses risks to agriculture and energy industries.
