1. What does 'abrupt' mean?

• A. Gradual
• B. Sudden
• C. Delayed
• D. Relaxed

Correct answer: B

Rationale: The correct answer is B: 'Sudden.' Abrupt means something that occurs suddenly, without warning or preparation. It is the opposite of gradual, delayed, or relaxed, which imply a slower or more gentle pace of change or action.

2. Which of the following structures has the lowest blood pressure?

• A. arteries
• B. arterioles
• C. venules
• D. veins

Correct answer: D

Rationale: Veins have the lowest blood pressure among the listed structures. This is because veins carry blood back to the heart at a slower rate compared to arteries, arterioles, and venules. The lower blood pressure in veins allows for the efficient return of blood to the heart despite the decreased pressure. Arteries have high blood pressure as they transport blood away from the heart at a rapid rate. Arterioles are smaller branches of arteries and contribute to resistance in the circulatory system, leading to a pressure drop. Venules are small blood vessels that collect blood from capillaries and gradually converge into veins, having slightly higher pressure than veins.

3. Which word is used incorrectly? 'Which procedure for giving injections was explained thoroughly to the student nurses.'

• A. procedure
• B. was
• C. explained
• D. thoroughly

Correct answer: B

Rationale: The correct answer is 'B - was.' In the original question, 'were' is incorrectly used as the verb, which should be singular to match the singular subject 'procedure.' The subject 'procedure' requires the singular form 'was' instead of the plural form 'were.' Choices A, C, and D are all used correctly in the sentence.

4. Certain non-Newtonian fluids exhibit shear thickening behavior. In this case, the fluid's viscosity:

• A. Remains constant with increasing shear rate
• B. Decreases with increasing shear rate (shear thinning)
• C. Increases with increasing shear rate
• D. Depends solely on the applied pressure

Correct answer: C

Rationale: When a non-Newtonian fluid exhibits shear thickening behavior, its viscosity increases with increasing shear rate. This means that as more force is applied to the fluid, its resistance to flow also increases, resulting in a higher viscosity. This phenomenon is opposite to shear thinning, where viscosity decreases with increasing shear rate. Therefore, in the case of shear thickening behavior, the correct answer is that the fluid's viscosity increases with increasing shear rate. Choices A, B, and D are incorrect because shear thickening behavior specifically involves an increase in viscosity with increasing shear rate, not remaining constant, decreasing, or depending on applied pressure.

5. Which word is used incorrectly in the following sentence? He received an oral dose initially, followed by an IV drip.

• A. received
• B. dose
• C. initial
• D. followed

Correct answer: C

Rationale: The word 'initial' is used incorrectly in the sentence. The correct word that should be used here is 'initially.' 'Initially' is an adverb that is used to indicate the beginning or starting point of an action, while 'initial' is an adjective that describes something as happening at the beginning of a process. In this context, the correct usage would be 'He received an oral dose initially, followed by an IV drip.' The other choices ('received,' 'dose,' and 'followed') are used correctly in the sentence and do not need any corrections.
