- B. One that looks for a cause
- C. One that examines the skin

Correct Answer: B
Rationale: A diagnostic test is a medical test or procedure performed to identify the cause of a health problem, disease, or condition. It helps healthcare providers make accurate diagnoses and determine appropriate treatments for patients. Choice A is incorrect because a diagnostic test does not locate a cure but rather aims to identify the cause of a health issue. Choice C is incorrect as a diagnostic test is not specifically for examining the skin but can involve various types of tests on different parts of the body. Choice D is incorrect as a diagnostic test is not performed on doctors but on patients to diagnose their health conditions.

Choose the best description for the term 'selected plants' in the following sentence: 'Saturated fat comes principally from animal food products and selected plants.'
- A. Plants that have been chosen
- B. Particular plants
- C. Top quality plants
- D. Restricted plants
Correct Answer: B
Rationale: The term 'selected plants' in this sentence refers to specific or particular plants that have been chosen intentionally for some reason. It implies that not all plants contribute to saturated fat but only specific ones. The term 'particular plants' best captures this meaning in the context provided. Choices A, C, and D are incorrect because 'selected plants' does not necessarily imply they are of top quality, plants that have been restricted, or chosen without reason. The emphasis is on the specificity of the plants chosen, making 'particular plants' the most suitable description.
To cauterize a wound is to ___________.
- A. soothe it
- B. cover it
- C. stitch it
- D. burn it
Correct Answer: D
Rationale: To cauterize a wound is to use heat or a chemical to burn the wound in order to stop bleeding and prevent infection. This process helps seal off blood vessels and close the wound by burning the affected tissue. Choice A, 'soothe it,' is incorrect because cauterization involves burning the wound, which is a controlled way of treating it, not soothing it. Choice B, 'cover it,' is incorrect as cauterization involves a more aggressive approach than just covering the wound. Choice C, 'stitch it,' is incorrect as it refers to using sutures to close a wound, which is different from cauterization that involves burning the wound to seal it.
Medicine that is given in inhalant form is ___________.
- A. dissolved
- B. injected
- C. taken orally
- D. breathed in
Correct Answer: D
Rationale: Medicine that is given in inhalant form is intended to be breathed in, typically through the mouth or nose. This allows the medication to reach the lungs directly and be absorbed into the bloodstream quickly. Examples of medications given in inhalant form include inhalers used for conditions like asthma and nebulizers for respiratory treatments. Choices A, B, and C are incorrect because medicine in inhalant form is not dissolved, injected, or taken orally; instead, it is inhaled to reach the lungs.
Choose the meaning of the word 'riddled' in the following sentence: 'The cavity, once opened, proved to be riddled with infection.'
- A. Challenged
- B. Overrun
- C. Separated
- D. Complete
Correct Answer: B
Rationale: The word 'riddled' in this context means filled with or affected by (something undesirable) to a great degree, which aligns with the definition of 'overrun.' In this sentence, the cavity is described as being full of infection, indicating that the infection has spread extensively throughout. 'Challenged' (choice A) implies being tested or provoked, which is not the meaning conveyed by 'riddled.' 'Separated' (choice C) means divided or isolated, which does not fit the context of the sentence. 'Complete' (choice D) means finished or whole, which is the opposite of what is described in the sentence where the cavity is full of infection.
What is the crystalline compound that is a product of protein metabolism known as?
- A. uracil
- B. urine
- C. ureter
- D. urea
Correct Answer: D
Rationale: Urea is the correct answer. It is the crystalline compound formed in the liver from the breakdown of proteins, a byproduct of protein metabolism. Urea is excreted by the kidneys in the form of urine, aiding in the elimination of nitrogenous waste from the body. Uracil (Choice A) is a nitrogenous base found in RNA, not a product of protein metabolism. Urine (Choice B) is the liquid waste excreted by the kidneys but not the crystalline compound resulting from protein metabolism. Ureter (Choice C) is a duct that carries urine from the kidneys to the bladder, not the compound produced from protein metabolism.
