HESI Radiography Limited License Exit - Blogs Sample Questions

An electrolyte panel measures which of the following?

Correct Answer:
carbon dioxide in the blood.


an electrolyte panel is a common medical test that measures several components in the blood to ensure proper body function and to aid in the diagnosis of certain conditions. when asked what an electrolyte panel measures, it's essential to understand the specific substances included in this test.

primarily, an electrolyte panel focuses on the levels of key electrolytes in the blood. electrolytes are minerals that carry an electric charge and are vital for numerous bodily functions. they help regulate nerve and muscle function, hydrate the body, balance blood acidity and pressure, and help rebuild damaged tissue. specifically, the electrolytes typically measured include sodium, potassium, chloride, and bicarbonate.

in addition to electrolytes, the panel often measures carbon dioxide (co2) levels in the blood. carbon dioxide is a waste product produced by the metabolism of oxygen during cellular respiration, and its measurement can provide important insights into the body’s metabolic state and the lungs' ability to remove co2.

it is important to note what an electrolyte panel does not measure, as it can be confused with other tests. for example, it does not measure brain activity or oxygen levels in the lungs directly. instead, other specialized tests are used for these purposes, such as electroencephalograms for brain activity or pulse oximetry for oxygen levels in the blood.

overall, an electrolyte panel is a crucial diagnostic tool used in regular physical exams and to monitor or diagnose medical conditions that affect electrolyte balance, such as kidney disease, heart conditions, and disorders causing electrolyte imbalances. it is a routine part of medical care in many health scenarios.

Which of the following is a form of image receptor?

Correct Answer:
cassette with film


the correct answer to the question "which of the following is a form of image receptor?" is "cassette with film." to understand why this is the correct choice, it's important to first define what an image receptor is in the context of radiographic imaging. an image receptor is a device that captures and converts x-ray energy into a visible image after the x-rays have passed through the body. this image is crucial for medical diagnosis as it allows for the visualization of the internal structures of the body.

a cassette with film is a traditional form of image receptor used in radiology. it consists of a light-proof casing that holds x-ray film and intensifying screens. when x-ray beams pass through the body, they strike the intensifying screens, which emit light proportional to the amount of x-ray exposure. this light, in turn, exposes the film. after chemical processing, the film displays the image of the body's internal structures. cassettes with film were widely used before the advent of digital imaging technologies but are still in use in some settings due to their reliability and high-quality image production.

other types of image receptors mentioned include image plates used in computed radiography, solid-state detectors found in direct digital radiography systems, portable digital radiography units, and fluoroscopic screens which are part of dynamic imaging systems used to provide real-time imaging for diagnostic and interventional procedures. each of these technologies captures x-ray energy and converts it into images, but they do so using different methods and materials.

in contrast, the other options listed—calibrator, voltage calculator, and infusion tube—are not types of image receptors. a calibrator is generally used to adjust the accuracy of a device, a voltage calculator helps in determining the electrical potential needed for operations, and an infusion tube is a medical device used for delivering fluids into a patient’s body. none of these devices are involved in the capture or conversion of x-ray energy into visible images.

therefore, among the listed options, "cassette with film" is the only correct answer as it directly relates to the capturing and visual representation of x-ray images, fulfilling the role of an image receptor in medical imaging.
