- A. An online social network
- B. A test for postgraduate students
- C. A well-known pharmaceutical
- D. A public health association
Correct answer: D
Rationale: The abbreviation CDC stands for the Centers for Disease Control and Prevention, which is a well-known public health association in the United States. The CDC is a federal agency under the Department of Health and Human Services, responsible for protecting public health and safety by controlling and preventing disease, injury, and disability. Choices A, B, and C are incorrect as they do not accurately describe what the CDC is known for; it is not an online social network, a test for postgraduate students, or a pharmaceutical company.

- A. pain
- B. bleeding
- C. fever
- D. coughing
Correct answer: B
Rationale: A hemostat is a surgical tool used to limit or control bleeding by clamping blood vessels during a surgical procedure. It helps to prevent excessive blood loss and maintain a clear surgical field, making it an essential instrument for managing bleeding during surgeries. Choices A, C, and D are incorrect as a hemostat is not used to limit pain, fever, or coughing, but specifically to control or limit bleeding.
3. What is another word for antidote?
- A. Purity
- B. Habitat
- C. Remedy
- D. Venom
Correct answer: C
Rationale: Corrected Question: What is another word for antidote? Rationale: An antidote is a substance that can counteract the effects of poison or disease. The term 'remedy' is often used synonymously with antidote to indicate a solution or cure for a particular problem or ailment. Choices A, B, and D are incorrect as they do not directly relate to the concept of antidote. 'Purity' refers to cleanliness or being free from contaminants, 'Habitat' is the natural environment where an organism lives, and 'Venom' is a poisonous substance typically injected by animals like snakes or insects.
4. The C in C-section stands for ___________.
- A. Carthusian
- B. Caesarean
- C. Cartesian
- D. Caedmon
Correct answer: B
Rationale: The correct answer is B: Caesarean. The C in C-section stands for 'Caesarean' after Julius Caesar, who was rumored to have been born via this surgical procedure. The term 'Caesarean' is derived from the Latin word 'caesus,' meaning cut or incised. Choice A, Carthusian, is incorrect as it does not relate to childbirth. Choice C, Cartesian, is unrelated to the medical procedure. Choice D, Caedmon, is also irrelevant in the context of C-sections.
5. What is the meaning of the word 'placebo' in the following sentence: 'Ten patients will receive the experimental drug while 10 take a placebo'?
- A. Fallback
- B. Substitute
- C. Control
- D. Curative
Correct answer: C
Rationale: In the context of the sentence, the word 'placebo' refers to a substance or treatment that resembles a real medical treatment but has no therapeutic effect. It is used as a standard against which the effects of the experimental drug are compared. A placebo is typically included in a control group in medical research to evaluate the actual effects of the experimental drug. Therefore, in this scenario, the placebo serves as a control to gauge the effectiveness of the experimental drug, making choice C the correct answer. Choices A, B, and D are incorrect because a placebo is not a fallback, substitute, or curative treatment in this context.
