1. 5\7 + 3\14 = ?

• A. 13\14
• B. 10/14
• C. 11/14
• D. 12/14

Correct answer: A

Rationale: To add fractions with different denominators, first find a common denominator. The least common denominator between 7 and 14 is 14. Convert 5/7 to 10/14: 5 / 7 = 10 / 14 5/7=10/14 Now add the two fractions: 10 / 14 + 3 / 14 = 13 / 14 10/14+3/14=13/14

2. The physician ordered 3,000 units of heparin; 5,000 U/mL is on hand. How many milliliters will you give?

• A. 0.5 ml
• B. 0.6 ml
• C. 0.75 ml
• D. 0.8 ml

Correct answer: B

Rationale: To calculate the volume of heparin needed, use the formula: Volume of Heparin = (Ordered Units / Concentration of Heparin). Substituting the values, Volume = (3,000 units / 5,000 U/mL) = 0.6 ml. Therefore, the correct answer is 0.6 ml. Choice A (0.5 ml) is incorrect as it results from an incorrect calculation. Choices C (0.75 ml) and D (0.8 ml) are also incorrect calculations based on the wrong formula application or mathematical errors.

3. Choose the meaning of the word 'adverse' in the following sentence: 'Occasionally, this medicine causes an adverse reaction.'

• A. Unfavorable
• B. Contrary
• C. Noticeable
• D. Startling

Correct answer: A

Rationale: The word 'adverse' in the sentence is most closely aligned with the meaning of 'unfavorable.' An adverse reaction to a medicine signifies a negative or harmful response, which supports the definition of unfavorable. Choice B, 'Contrary,' does not accurately capture the negative connotation associated with 'adverse.' Choice C, 'Noticeable,' does not reflect the meaning in the context provided. Choice D, 'Startling,' suggests a more sudden or surprising nature, which is not the primary meaning of 'adverse' in this context.

4. Which system does the esophagus belong to?

• A. Endocrine system
• B. Digestive system
• C. Respiratory system
• D. Nervous system

Correct answer: B

Rationale: The esophagus is part of the digestive system. It is a muscular tube that connects the mouth to the stomach, allowing the passage of food and liquids from the mouth to the stomach for digestion. The esophagus plays a crucial role in the process of swallowing and digestion, which are essential functions of the digestive system. Choices A, C, and D are incorrect because the esophagus is not associated with the endocrine, respiratory, or nervous systems.

5. Choose the best description for the term 'selected plants' in the following sentence: 'Saturated fat comes principally from animal food products and selected plants.'

• A. Plants that have been chosen
• B. Particular plants
• C. Top quality plants
• D. Restricted plants

Correct answer: B

Rationale: The term 'selected plants' in this sentence refers to specific or particular plants that have been chosen intentionally for some reason. It implies that not all plants contribute to saturated fat but only specific ones. The term 'particular plants' best captures this meaning in the context provided. Choices A, C, and D are incorrect because 'selected plants' does not necessarily imply they are of top quality, plants that have been restricted, or chosen without reason. The emphasis is on the specificity of the plants chosen, making 'particular plants' the most suitable description.
