1. The electrolytes in human bodies include sodium, potassium, calcium, and ___________, among others.

• A. magnesium
• B. manganese
• C. magnetite
• D. manganite

Correct answer: A

Rationale: Magnesium is another essential electrolyte in the human body, along with sodium, potassium, and calcium. Magnesium plays a crucial role in various bodily functions, including muscle and nerve function, regulating blood pressure, and supporting the immune system. Manganese (Choice B), magnetite (Choice C), and manganite (Choice D) are not electrolytes found in the human body. Manganese is a mineral but not an electrolyte, while magnetite and manganite are compounds and not essential electrolytes for bodily functions.

2. Which sentence correctly uses a colon?

• A. She had one goal: to win the race.
• B. He needs milk, eggs, and bread.
• C. The meeting is at 3 PM.
• D. She bought milk, eggs, bread.

Correct answer: A

Rationale: The correct answer is A: 'She had one goal: to win the race.' This sentence uses a colon to introduce the purpose or explanation that follows. It is a grammatically correct use of a colon. Choice B is incorrect as the colon is not needed after 'needs'; a list of items follows, which does not require a colon. Choice C is a simple statement of time and does not require a colon. Choice D is also incorrect since a colon is not suitable after 'bought'; the items bought are listed without the need for a colon.

3. The eye drops were intended to _____ the pupils for the eye exam.

• A. dilate
• B. constrict
• C. enlarge
• D. decrease

Correct answer: A

Rationale: The correct answer is 'dilate.' Eye drops are used to dilate the pupils, meaning to widen or enlarge them, which is necessary for an eye exam to allow more light to enter the eye. 'Constrict' (choice B) means to make smaller, which is the opposite effect needed for an eye exam. 'Enlarge' (choice C) is similar in meaning to dilate but is not the correct term used in this context. 'Decrease' (choice D) means to make less or reduce, which is also the opposite of what is required for an eye exam.

4. Everyone thought that was the __________ test of the whole course.

• A. Most easiest
• B. Most easy
• C. Easiest
• D. Easy

Correct answer: C

Rationale: The correct answer is C: 'Easiest.' The word 'easiest' is the correct superlative form of 'easy,' which is used to compare one item against others in terms of degree. 'Most easiest' and 'most easy' are grammatically incorrect. Choice D, 'Easy,' is incorrect as it is not a superlative form and does not convey a comparison of the test against others in the course.

5. A tuberculin skin test should be read within 24 hours of administration.

• A. of
• B. before
• C. after
• D. during

Correct answer: A

Rationale: The correct preposition to use after 'within 24 hours' in this context is 'of.' Therefore, the tuberculin skin test should be read within 24 hours of administration. The other choices ('before,' 'after,' 'during') do not correctly convey the relationship between the timing of reading the test and the administration.
