1. Which of the following words fits best in the following sentence? ___________ having finished her coursework, Lorene expects to spend another year on campus.

• A. Despite
• B. Although
• C. Thus
• D. However

Correct answer: A

Rationale: The correct answer is 'Despite.' 'Despite' is the best word to use in the sentence because it shows a contrast between Lorene having finished her coursework and her expectation to spend another year on campus. The word 'Despite' signals that there is an unexpected or contrary situation, emphasizing the contradiction between the two parts of the sentence. 'Although' (choice B) introduces a contrast but is not as strong as 'Despite' in highlighting the contradiction. 'Thus' (choice C) and 'However' (choice D) do not convey the intended contrast needed in this context, making them incorrect choices.

2. What is the correct formula for potassium chloride?

• A. NaCl
• B. KCl
• C. KCl
• D. ClK

Correct answer: B

Rationale: The correct formula for potassium chloride is KCl. In chemical formulas, the symbol for the cation (positive ion) comes first followed by the symbol for the anion (negative ion). Potassium is represented by the symbol K, while chloride is represented by the symbol Cl. Therefore, the formula for potassium chloride is KCl. Choice A (NaCl) is the formula for sodium chloride, not potassium chloride. Choice C is a duplicate of choice B, and choice D (ClK) is an incorrect arrangement of the symbols for potassium and chloride.

3. Which statement is not listed as a detail within the passage?

• A. Changes in the ECG are typically used for the diagnosis of abnormal cardiac rhythm.
• B. The signal has a characteristic record called the electrocardiogram.
• C. The 'wave of excitation' starts at the SA node.
• D. The 'wave of excitation' spreads through the heart wall and is accompanied by electric changes.

Correct answer: A

Rationale: The corrected statement should be: Changes in the ECG are not typically used for the diagnosis of abnormal cardiac rhythm. The passage mentions that the heart sends out electric currents in waves, and the 'wave of excitation' spreads through the heart wall accompanied by electric changes. It details the process of how the heart's electric impulses are recorded and how abnormalities can be detected. However, it does not state that ECG changes are specifically used for diagnosing abnormal cardiac rhythms. Choice A is the correct answer because it misrepresents the information provided in the passage. Choices B, C, and D are all supported by the passage and align with the details mentioned regarding the electrocardiogram and the wave of excitation in the heart.

4. What does Lateral mean?

• A. Near the midline
• B. Away from the midline
• C. At the top of the body
• D. On the side

Correct answer: D

Rationale: The correct answer is D: 'On the side.' Lateral means situated on the side or away from the midline. Choices A, B, and C are incorrect because lateral specifically refers to a position that is situated away from the midline, not near it, at the top of the body, or on the side.

5. 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.
