Question 1

Palpating the number of times the heart beats per minute is referred to as the:

Accepted Answer

Palpating the number of times the heart beats per minute is referred to as the pulse. Diastolic pressure and systolic pressure refer to the pressure measured by a blood pressure cuff, while respiratory rate is the number of breaths a person takes per minute.

Question 2

In an x-ray image, metals such as lead or steel appear:

Accepted Answer

Metals such as lead or steel appear white in an x-ray image because they absorb most of the x-rays and do not allow them to pass through, resulting in a bright white image.

Question 3

Following a musculoskeletal injury, the application of ice can help to reduce swelling. Which term best describes this intervention?

Accepted Answer

Cryotherapy is the use of cold therapy to reduce inflammation and swelling. Chemotherapy refers to the treatment of cancer using drugs, pharmacotherapy is the use of medications to treat a disease or condition, and radiotherapy is the use of radiation to treat cancer or other conditions. None of these terms are appropriate to describe the use of ice to treat a musculoskeletal injury.

Question 4

You are working with a patient who has cancer. Which type of medication is used to kill cancer cells?

Accepted Answer

Cytotoxic medications, also known as chemotherapy, are used to kill cancer cells. Cryotherapy involves freezing tissues and is typically used for treating pre-cancerous or cancerous skin lesions. Radiologic medications are used in radiation therapy to kill cancer cells. Systolic refers to the pressure in the arteries when the heart beats, and is not a type of cancer medication.

Question 5

You are working with a patient who was prescribed penicillin, which is an example of:

Accepted Answer

Penicillin is an antibiotic, which is a medication used to treat bacterial infections. Analgesics are used to relieve pain, antineoplastics are used to treat cancer, and cytotoxic therapy is used to kill cells, including cancer cells.

Question 6

A term that means pertaining to a procedure that uses an illuminated instrument for the visualization of the interior of a body cavity or organ is:

Accepted Answer

The term "endoscopic" specifically refers to the use of an illuminated instrument called an endoscope for visualization within the body. "Fluoroscopic" refers to the use of continuous X-ray imaging, which is not always used in endoscopic procedures. "Fluoroscope" refers to the actual imaging device used in fluoroscopy, and "endoscope" refers to the instrument itself, rather than the procedure.

Question 7

While reviewing a chart, you note that the patient has had an ultrasound. Which of the following terms best describes this type of testing?

Accepted Answer

Ultrasound is also known as echography, as it uses sound waves to create images of the inside of the body.

Question 8

Which of the following statements is true of antimicrobials?

Accepted Answer

Antimicrobials are drugs that are designed to destroy or inhibit the growth of microbes, including bacteria, viruses, fungi, and parasites. Analgesics are drugs that are used to relieve pain, and antibiotics are a specific type of antimicrobial that are used to treat bacterial infections only.

Question 9

Hypothermia can be detected using:

Accepted Answer

A tympanic thermometer is the best choice for detecting hypothermia as it measures the temperature inside the ear canal, which is a reliable indicator of core body temperature. Cryotherapy, radiography, and sonography are not appropriate for detecting hypothermia.

Question 10

The term that means to introduce a hollow flexible tube that can be inserted into a cavity of the body to withdraw or instill fluids, perform tests, or visualize a vessel or cavity is:

Accepted Answer

The answer of The term that means to introduce a...

Question 11

A physician is completing a visual inspection of the body by means of an illuminated instrument for the visualization of the interior of a body cavity or organ. This inspection is called an:

Accepted Answer

The inspection being described is typically done using an endoscope, which is an illuminated instrument used for the visualization of the interior of a body cavity or organ. Choice A is incorrect as an echogram is an image created by ultrasound. Choice B is incorrect as echography is the process of creating images using ultrasound. Choice C is incorrect as an endoscope is the device used for the inspection, not the inspection itself.

Question 12

The patient complains of pain in the right arm. Pain experienced by the patient is:

Accepted Answer

Pain is subjective and only experienced by the patient, thus it is a symptom. A sign would be an objective observation made by a healthcare professional, such as swelling or redness in the arm. Prognosis refers to the predicted outcome of a disease or condition and is not relevant to describing the patient's current symptom.

Question 13

An instrument that projects an x-ray image on a screen during fluoroscopy is called a:

Accepted Answer

A fluoroscope is specifically designed to project x-ray images onto a screen in real time during fluoroscopy procedures. A microscope is used for magnifying and examining small objects, a radiograph is a still x-ray image, and a stethoscope is used for auscultation of bodily sounds.

Question 14

Substances that do not permit the passage of x-rays are described as:

Accepted Answer

Radiopaque substances absorb or block the passage of x-rays, making them visible on a radiograph or x-ray image.

Question 15

An adjective that describes a disease showing little change or slow progression is:

Accepted Answer

Chronic describes a disease or condition that persists over a long period of time and may have little change or slow progression. Acute refers to a disease or condition that comes on suddenly and is often severe. Diagnosis refers to the identification of a disease through examination and testing. Symptom refers to a physical or mental manifestation of a disease or condition.

Question 16

Which of the following statements is true?

Accepted Answer

A neoplasm can be either benign or malignant, so option D is the correct statement. Option A is incorrect because analgesics are used to manage pain, not treat neoplasms. Option B is incorrect because a neoplasm can be both benign or malignant, but a malignant tumor is always cancerous. Option C is incorrect because remission refers to the absence of signs or symptoms of a disease, not a neoplasm itself.

Question 17

In measurements of blood pressure, the higher reading is the _____ pressure.

Accepted Answer

The higher reading in blood pressure measurements is the systolic pressure, which is the pressure in the arteries when the heart beats and pumps blood out. The diastolic pressure is the lower reading, which is the pressure in the arteries when the heart is at rest between beats. The other answer choices (symptomatic and tympanic) are not related to blood pressure measurements.

Question 18

A 32-year-old woman is having a 20-week ultrasound during her first pregnancy. Which term relates to this procedure?

Accepted Answer

A 20-week ultrasound during pregnancy is typically referred to as a sonogram, which uses high-frequency sound waves to create an image of the developing fetus. Inspection refers to a visual examination, palpation involves feeling for abnormalities or changes in tissue texture, and tomography involves creating detailed images of a specific section of the body using X-rays or other imaging techniques.

Question 19

The branch of medicine that specializes in the diagnosis and treatment of diseases with x-rays and radioactive substances is:

Accepted Answer

Radiology specifically focuses on the use of x-rays and radioactive substances in diagnosing and treating diseases. Pharmaceutics and pharmacology deal with drugs and their effects on the body, while tomography is a type of radiological imaging technique.

Question 20

The use of radiopaque materials to make internal organs visible is called:

Accepted Answer

The use of radiopaque materials to make internal organs visible is called contrast imaging. This technique involves injecting or ingesting a contrast agent, which is a substance that blocks X-rays and shows up as a bright white area on the resulting X-ray image. Contrast imaging is commonly used for procedures such as CT scans, MRI scans, and angiograms.
