What is the best description for the abbreviation CDC?

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.

Correct Answer: B

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

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.

Correct Answer: C

Rationale: Enervated refers to being weakened or lacking energy, so an enervated patient would likely be fatigued or tired. This term does not specifically imply anxiety, immaturity, or fear, making 'tired' the most suitable choice in this context. 'Anxious' (choice A) means feeling nervous or worried, which is not directly related to being enervated. 'Immature' (choice B) refers to lacking maturity or development, which is unrelated to the patient's energy level. 'Frightened' (choice D) means feeling afraid or scared, which is not necessarily connected to being enervated.

Correct Answer: D

Rationale: If a lump under the skin is palpable, it means that it can be felt or touched. Palpable lumps can be detected by touch, which can lead to further evaluation or examination by a healthcare professional to determine the cause and appropriate treatment. The correct answer is 'D' because when a lump is palpable, it means it can be physically felt, indicating its presence under the skin. Choices A, B, and C are incorrect because the palpability of a lump does not automatically indicate malignancy, bursting, or warmth.
