HESI A2 Vocabulary 2024
1. A hemostat would be used to limit ___________.
- 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.
2. 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.

- D. Welt
Correct answer: B
Rationale: In the sentence, "laceration" is referring to a deep cut or tear in the skin. It is often associated with injuries that are caused by sharp objects or trauma. Therefore, the most appropriate meaning of "laceration" in this context is a cut.

- A. drug
- B. procedure
- C. book
- D. muscle group
Correct answer: A
Rationale: The abbreviation PDR stands for Physician's Desk Reference, which is a widely used book containing information about prescription drugs, including their uses, side effects, and dosages. Therefore, the abbreviation PDR is associated with drugs. Choices B, C, and D are incorrect because PDR specifically relates to drugs and not procedures, books, or muscle groups.

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.
