TEAS 7 science practice questions Questions
Question 1 of 5
Which of the following is a condition characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, coughing, and shortness of breath?
Correct Answer: C
Rationale: Asthma is a chronic condition characterized by inflammation and narrowing of the airways, leading to symptoms such as wheezing, coughing, and shortness of breath. Pneumonia, caused by an infection in the lungs, presents with symptoms like fever, chills, and cough with sputum. Tuberculosis is a bacterial infection that primarily affects the lungs, leading to symptoms such as persistent cough, chest pain, and weight loss. Emphysema, a type of chronic obstructive pulmonary disease, is characterized by the destruction of the air sacs in the lungs, causing symptoms like shortness of breath and chronic cough. Therefore, among the options provided, asthma best fits the description of a condition with airway inflammation and narrowing.
Question 2 of 5
Which of the following is a condition characterized by a loss of bone density and increased risk of fractures?
Correct Answer: C
Rationale: Osteoporosis is a condition characterized by a loss of bone density, leading to fragile bones and an increased risk of fractures. Osteoarthritis is a degenerative joint disease affecting cartilage, Rickets is caused by a deficiency in vitamin D leading to impaired bone development, and Scoliosis is an abnormal sideways curvature of the spine. Therefore, the correct answer is osteoporosis as it specifically pertains to decreased bone density and fracture risk, distinguishing it from the other conditions listed.
Question 3 of 5
What is meant by the term 'goiter'?
Correct Answer: B
Rationale: A goiter is a condition characterized by the abnormal enlargement of the thyroid gland. This enlargement can be caused by various factors such as iodine deficiency, thyroid nodules, inflammation, or other thyroid disorders. It is not associated with the overproduction of cortisol (Choice A), underproduction of parathyroid hormone (Choice C), or deficiency of growth hormone (Choice D). Therefore, the correct answer is B, excessive growth of the thyroid gland.
Question 4 of 5
What is the primary function of the liver?
Correct Answer: D
Rationale: The primary function of the liver is to detoxify harmful substances in the body. While the liver does produce bile to aid in the digestion of fats, this is not its primary function. Bile is stored in the gallbladder and released into the small intestine for fat digestion. Storing energy in the form of glycogen is a function of the liver, but not its primary one. Glycogen serves as a reserve of glucose. Although the liver produces proteins that assist in blood clotting, such as fibrinogen and prothrombin, this is not its main function. These proteins play a crucial role in blood clotting to prevent excessive bleeding. Therefore, the primary role of the liver is to detoxify harmful substances by processing and removing toxins, drugs, alcohol, and other harmful substances from the bloodstream, thereby reducing their harmful effects.
Question 5 of 5
Which property of a substance refers to its ability to be hammered or pressed into thin sheets without breaking?
Correct Answer: A
Rationale: Malleability is the correct answer as it is the property of a substance that allows it to be hammered or pressed into thin sheets without breaking. This property is crucial for materials like metals that need to be shaped without breaking. Ductility, on the other hand, refers to the ability of a substance to be drawn into thin wires, not hammered into sheets. Viscosity is a measure of a fluid's resistance to flow, indicating its thickness or thinness, and is unrelated to the ability to be hammered. Conductivity, on the other hand, refers to a substance's ability to conduct electricity or heat, which is not related to its ability to be hammered or pressed into thin sheets.
