Ultrasound is sound waves with frequencies higher than the upper audible limit of human hearing. Ultrasound is not different from "normal" (audible) sound in its physical properties, except that humans cannot hear it. This limit varies from person to person and is approximately 20 kilohertz (20,000 hertz) in healthy young adults. Ultrasound devices operate with frequencies from 20 kHz up to several gigahertz. ultrasound is a safe and painless test that uses sound waves to make images of the abdomen (belly).

During the examination, an ultrasound machine sends sound waves into the abdominal area and images are recorded on a computer. The black-and-white images show the internal structures of the abdomen, such as the appendix, intestines, liver, gall bladder, pancreas, spleen, kidneys, and urinary bladder. The gel is applied to the scan area, before contacting the ultrasound probe to your Ultrasonic waves generated from the probe are reflected from the boundary of the tissue, and the probe receive reflected waves to make an ultrasound image. However, the larger the difference in acoustic characteristics between the two tissues, the stronger the reflection and the stronger the echo (white on the screen) appears. The acoustic properties (resistance) of each tissue are related to their density, which is greater in order of bone> soft tissue> fat> air. Therefore, if you apply ultrasonic probe without gel, 99.9% of ultrasonic waves are reflected at the boundary of air - soft tissue (body). Ultrasound image should show the difference between the tissues in body (normal-lesion, etc.), not the difference between the air and body.

To solve this situation, the gel is used. In other words, when the acoustic resistance of the two media is made equal by using gel, ultrasonic waves are transmitted to body without reflection.

The other purpose of the gel is the role of lubrication, which moves the probe smoothly when performing a ultrasound scan. If the gel is not used, it may be stiff and the patient may feel pain.

Answer:

An ultrasound scan uses high-frequency sound waves to make an image of a person's internal body structures. Doctors commonly use ultrasound to study a developing fetus (unborn baby), a person's abdominal and pelvic organs, muscles and tendons, or their heart and blood vessels. The ultrasound sound waves have a hard time traveling through air, so the gel prevents any extra air space between the probe and your skin in order to create a clear image of the fetus.

A nurse is performing a venipuncture on an older adult client whose veins are difficult to locate. Which of the following action
evablogger [386]

When doing venipuncture on an elderly client whose veins are hard to find, the nurse should touch the skin around the insertion site.

Location for Venipuncture:

  • The two veins most frequently utilized for venipuncture are -
  1. the cephalic and
  2. median cubital veins.
  • Possible locations include the dorsum of the arm's basilic vein or the dorsal veins of the hands.
  • The basilic vein, which is found on the pinkie side of the arm and is adjacent to the brachial arteries and median nerve, must only be utilized if there are no other more noticeable arm veins, due to its close closeness to both.
  • Only in extreme cases can veins in the ankle and foot be used. Avoid touching the veins on the inside of the wrist. A few additional websites ought to be avoided as well.

Describe the osmotic gradient in the kidney and explain how the
Shtirlitz [24]

Answer:

Explanation:

The osmotic gradient in the kidney typically in the medulla is a process that generates urine that is 5 times more concentrated so as to reduce the loss of water from the body.

The countercurrent multiplication is a process that uses energy to produce the osmotic gradient in the kidney, this process facilitates the reabsorption of water from the tubular fluid. This mechanism moves the sodium chloride from the tubular fluid to the interstitial space of the kidneys. The osmotic gradient can be developed in two ways:

1. The single effect: This involves the transport of sodium chloride from the tubular fluid and moved to the ascending limb then finally to the interstitial fluid. As a result of this, the water moves passively down to the concentration gradient out of the tubular fluid than to the descending limb of the interstitial space, until the equilibrium is achieved.  

2. Fluid flow method: The tubular fluid enters into the descending limb. This pushes the fluid into high osmolarity typically down the tube. This way the osmotic gradient develops.

Who is a socio-economically disadvantaged child? Explain any four ways forhelping such a child.
yuradex [85]
A socio-economically disadvantaged child is the one who is disadvantaged in terms of social position and economic position. Such children have limited resources in terms of education, money and future options. Four ways of helping such children are as follows:
