The abbreviation YOB on a medical form refers to a patient's ___________.

Correct Answer: D

Rationale: The abbreviation YOB stands for 'Year of Birth.' It is used on medical forms to refer to a patient's birthdate, indicating the year in which the individual was born. Therefore, the correct answer is D. Choices A, B, and C are incorrect because YOB does not pertain to weight, ethnicity, or symptoms; it specifically relates to the patient's birthdate.

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.

Correct Answer: C

Rationale: In this context, the word 'quandary' refers to a state of uncertainty or confusion caused by being faced with a difficult decision or choice. This matches the meaning of option C.

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.

Correct Answer: D

Rationale: In the given sentence, the word 'establish' is used in the context of identifying or finding out the specific causes of contact dermatitis through patch tests. The most fitting description for 'establish' in this context is 'Determine,' as it signifies the action of figuring out or ascertaining the specific causes. 'Launch,' 'introduce,' and 'endorse' do not capture the essence of what the physicians are doing in this scenario. They are not launching, introducing, or endorsing the causes; instead, they are trying to determine them through the patch tests.
