1. What factor is used to convert pounds to kilograms?

• A. 1.8
• B. 2.2
• C. 2.5
• D. 2

Correct answer: B

Rationale: The correct factor to convert pounds to kilograms is 2.2. To perform the conversion, you need to divide the number of pounds by 2.2. Choice A (1.8) is incorrect as it's not the standard conversion factor. Choice C (2.5) and Choice D (2) are also incorrect factors for converting pounds to kilograms.

2. Choose the meaning of the word 'persistent' in the following sentence: 'The elderly patient has been fighting a persistent cold.'

• A. Typical
• B. Harmless
• C. Without cure
• D. Lasting a long time

Correct answer: D

Rationale: In the sentence provided, the word 'persistent' is used to describe the cold, indicating that it has been lasting for a long time without going away easily. This choice emphasizes the prolonged nature of the cold. Choices A, B, and C are incorrect because 'persistent' does not mean 'typical,' 'harmless,' or 'without cure' in this context. The key is to focus on the word's meaning in relation to the duration of the cold.

3. The abbreviation DTs on a patient’s chart stands for ___________.

• A. deep tendon reflex
• B. descending thorax
• C. delirium tremens
• D. dextrose in water

Correct answer: C

Rationale: The abbreviation DTs on a patient's chart stands for delirium tremens, which is a severe form of alcohol withdrawal. Symptoms of delirium tremens include confusion, hallucinations, severe agitation, seizures, and autonomic instability. This condition requires prompt medical treatment to prevent serious complications. Choices A, B, and D are incorrect. Deep tendon reflex (A) refers to the reflex response elicited by tapping a tendon with a reflex hammer, descending thorax (B) is not a recognized medical term, and dextrose in water (D) is a solution used for various medical purposes but is not represented by the abbreviation DTs.

4. Another word for CONTEMPLATING is?

• A. Impasse
• B. Impartial
• C. Pondering
• D. Emending

Correct answer: C

Rationale: "Pondering" is another word for contemplating because it means to think about something carefully or thoroughly. Both terms imply deep reflection or consideration of a subject or idea. Therefore, "pondering" best captures the meaning of contemplating among the given choices.

5. The efficiency (η) of a heat engine is defined as the ratio of the net work done (Wnet) by the engine to the heat input (Qh) from the hot reservoir. The relationship is expressed as:

• A. η = Wnet / Qh
• B. η = Qh / Wnet
• C. η = Wnet x Qh
• D. η = (Wnet + Qh) / 2

Correct answer: A

Rationale: The correct formula for efficiency (η) of a heat engine is η = Wnet / Qh. Efficiency is defined as the ratio of the net work done by the engine (Wnet) to the heat input from the hot reservoir (Qh). This formula shows how effectively the engine converts heat into useful work, making choice A the correct answer. Choices B, C, and D present incorrect relationships between efficiency, net work done, and heat input, leading to their incorrectness.
