1. 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.

2. Choose the best summary of the passage about Sunny-Side Up.

• A. Light-skinned people need a maximum of 15 minutes a day in direct sunlight to achieve the benefits of the sun’s rays.
• B. Spending too much time indoors can wreak havoc with your circadian rhythms, leach vitamin D from your bones, and damage your immune system.
• C. Although negative effects of sunlight are well known, people should be aware that some sunlight is necessary and beneficial.
• D. You can avoid direct sunlight but still reap the benefits of a day in the sun by using sunscreen or tinted glass.

Correct answer: C

Rationale: The best summary captures the essence of the passage, which acknowledges the well-known negative effects of sunlight while also emphasizing the necessity and benefits of sunlight exposure. C accurately reflects this balanced view, making it the most appropriate choice.

3. If 7 is to 9 as x is to 63, find the value of x.

• A. x = 49
• B. x = 39
• C. x = 50
• D. x = 59

Correct answer: A

Rationale: To find the value of x, set up the proportion 7/9 = x/63. Cross multiply to get 7*63 = 9*x. This simplifies to 441 = 9x. Divide both sides by 9 to solve for x, giving x = 49. Therefore, the correct answer is A. Choice B (x = 39), Choice C (x = 50), and Choice D (x = 59) are incorrect as they do not match the correct calculation based on the proportion set up.

4. What is the average normal body temperature in degrees Celsius?

• A. 30°C
• B. 32°C
• C. 35°C
• D. 37°C

Correct answer: D

Rationale: The average normal body temperature in degrees Celsius is 37°C. This temperature is considered the standard measurement for the human body under normal conditions. It is essential to know this baseline temperature for monitoring health and detecting abnormalities such as fever. Choice A, 30°C, is too low for the average normal body temperature. Choice B, 32°C, is also below the standard normal body temperature. Choice C, 35°C, is closer but still lower than the average normal body temperature of 37°C.

5. For the core of an electromagnet, a material with high:

• A. Resistivity is ideal
• B. Permeability is preferred
• C. Permittivity is crucial
• D. Dielectric strength is essential

Correct answer: B

Rationale: A material with high permeability is preferred for the core of an electromagnet because it allows magnetic field lines to pass through it easily, enhancing the strength of the magnetic field generated. Choice A is incorrect because high resistivity would impede the flow of current in the coil, reducing the strength of the magnetic field. Choice C is incorrect as permittivity is related to electric fields, not magnetic fields. Choice D is also incorrect because dielectric strength is about insulating materials against breakdown under an electric field, not relevant to enhancing magnetic fields.
