Question 1

_____ analyzes the interaction of low-frequency sound waves with tissues to create moving images of internal organs.

Accepted Answer

Ultrasound is the medical imaging technique that analyzes the interaction of low-frequency sound waves with tissues to create moving images of internal organs. Computed tomography, nuclear medicine, and radiography use different technologies to produce medical images.

Question 2

_____ is the process of identifying a disease or disorder.

Accepted Answer

Diagnosis is the process of identifying a disease or disorder. Acute and chronic refer to the duration of the disease or disorder, while prognosis refers to the likely outcome or course of the disease.

Question 3

______ uses radioactive materials to create contrast in the body and help form images of the structure and function of organs.

Accepted Answer

Nuclear medicine uses radioactive materials to create images of the structure and function of organs. Computed tomography (CT) uses X-rays to create images, radiography also uses X-rays to create images, and ultrasound uses sound waves to create images.

Question 4

A disease that causes no signs or symptoms is called an _____ disease.

Accepted Answer

An asymptomatic disease is a disease that causes no signs or symptoms. This means that an individual can be infected with the disease, but not know it because they do not show any outward signs of illness.

Question 5

In _____, the body's organ systems normally maintain temperature, pH, blood composition, and fluid levels within a precise range.

Accepted Answer

Homeostasis refers to the body's ability to maintain internal stability and balance despite external changes. This includes regulating temperature, pH, blood composition, and fluid levels within a precise range to promote optimal functioning of the body's organ systems. Disease and pathology refer to conditions that disrupt normal bodily function, while health refers to the overall state of being free from illness or injury.

Question 6

_____ uses computers and x-rays to create three-dimensional images of internal structures.

Accepted Answer

Computed tomography (CT) uses computers and x-rays to create three-dimensional images of internal structures. Nuclear medicine uses radioactive materials to create images, radiography uses x-rays to produce two-dimensional images, and ultrasound uses high-frequency sound waves to produce images.

Question 7

An example of a _____ is a person confined to bed with a serious fracture developing pneumonia due to inactivity.

Accepted Answer

A complication is a secondary disease or condition that occurs during the course of a primary disease or condition. In this case, pneumonia is a complication that has developed as a result of the person being confined to bed with a serious fracture.

Question 8

_____ is the percentage of a population that is affected with a particular disease at a given time.

Accepted Answer

Prevalence is the percentage of a population that is affected with a particular disease at a given time. Incidence is the number of new cases of a disease in a population over a particular period of time. Morbidity refers to the proportion of a population that is affected by a particular health condition or disease, regardless of whether it is fatal or non-fatal. Mortality refers to the incidence of death in a population.

Question 9

_____, producing sounds by tapping on specific areas of the body with fingers, hands, or small instruments, allows evaluation of the size, consistency, and borders of the body organs, and the presence or absence of fluid in body areas.

Accepted Answer

Percussion is the technique of producing sounds by tapping on specific areas of the body with fingers, hands, or small instruments. This allows evaluation of the size, consistency, and borders of the body organs, and the presence or absence of fluid in body areas.

Question 10

The predicted course and outcome of the disease is known as the _____.

Accepted Answer

The predicted course and outcome of the disease is referred to as the prognosis. A diagnosis is the identification of a particular condition, exacerbation refers to a worsening of symptoms, and relapse refers to the return of symptoms after a period of improvement.

Question 11

A disease that will end in death is called a _____ disease.

Accepted Answer

A terminal disease is one that is incurable and will ultimately end in the patient's death.

Question 12

Some diseases enter a period of _____ during which signs and symptoms subside or disappear.

Accepted Answer

Remission is a period during which the signs and symptoms of a disease are reduced or disappear. This can happen spontaneously or as a result of treatment. Remission does not necessarily mean cure, as the disease may still be present but not active.

Question 13

_____ is a deviation from normal structure or function in the body that interrupts or modifies the performance of vital functions.

Accepted Answer

A disease is defined as a deviation from normal structure or function in the body that interrupts or modifies the performance of vital functions. This can manifest in a wide range of ways, from minor discomfort to life-threatening conditions. Examples of diseases include cancer, diabetes, and heart disease.

Question 14

An example of a _____ is rheumatic fever causing permanent damage to the heart.

Accepted Answer

A sequela is a condition or complication that is the result of a previous disease or injury. In this case, rheumatic fever is the initial disease and the permanent damage to the heart is the sequela.

Question 15

_____ is the number of deaths that occur among people with a certain disease.

Accepted Answer

Mortality refers to the number of deaths that occur among people with a certain disease. Incidence refers to the number of new cases of a disease in a population over a certain time period. Morbidity refers to the prevalence of a specific disease or condition in a population. Prevalence refers to the total number of cases of a disease in a population at a certain point in time, including both new and existing cases.

Question 16

_____ refers to a visual examination of the external surface of the body, its movements, and posture for abnormalities or evidence of disease.

Accepted Answer

Inspection refers to visual examination of the external surface of the body and its movements and posture. Auscultation is the act of listening to internal sounds in the body, palpation involves using touch to assess the body, and percussion involves tapping on the body to produce sounds for diagnostic purposes.

Question 17

_____ is the number of cases of a disease in a population.

Accepted Answer

The answer of _____ is the number of cases of...

Question 18

A period of _____ occurs when signs and symptoms grow more severe.

Accepted Answer

An exacerbation is a period when signs and symptoms of a condition become more severe. This can happen in chronic conditions, such as autoimmune diseases, where symptoms can flare up for periods of time.

Question 19

Examples of _____ diseases include heart disease, cancer, stroke, diabetes, and arthritis.

Accepted Answer

Chronic diseases are long-term conditions that do not have a cure and require ongoing management. The listed diseases (heart disease, cancer, stroke, diabetes, and arthritis) are all chronic diseases.

Question 20

_____ data allows the determination of the impact and significance of a disease for a given population.

Accepted Answer

Prevalence data provides information about the proportion of individuals in a population who currently have a particular disease, while incidence data describes the rate at which new cases of the disease are occurring. Morbidity data describes the proportion of individuals who have a particular illness or disease in a given population, while mortality data refers to the number of deaths that result from a particular illness or disease. Prevalence data is often used to determine the overall impact of a disease on a population, as it takes into account both new cases and existing cases of the disease.
