NEW QUESTION # 138
Reading Comprehension
Passage:
Public health campaigns often focus on smoking cessation because smoking is a leading cause of preventable disease. Reducing smoking rates can significantly lower the incidence of heart disease, lung cancer, and stroke.
Which outcome is directly associated with reducing smoking rates?
Answer: B
Explanation:
The passage clearly states that reducing smoking rates lowers the incidence of heart disease, lung cancer, and stroke. These are chronic diseases, making option C the correct answer. The other options are either not mentioned or incorrect. On the NEX exam, cause-and-effect reading questions require identifying outcomes that are directly linked to actions described in the passage. Choosing the most clearly stated effect is essential.

NEW QUESTION # 139
Given that 1 foot = 12 inches and 3 feet = 1 yard, how many inches are in 2.5 yards?
Answer: C
Explanation:
This is a unit-conversion problem involving yards, feet, and inches. First, convert yards to feet. Since 1 yard equals 3 feet, multiply: 2.5 × 3 = 7.5 feet. Next, convert feet to inches using the given conversion of 12 inches per foot. Multiply: 7.5 × 12 = 90 inches. Therefore, the correct answer is C. Option A (72 inches) represents only 6 feet. Option B (45 inches) results from converting yards directly to inches incorrectly. Option D (54 inches) represents 4.5 feet. On the NEX exam, multi-step measurement conversions are common, and accuracy depends on converting one unit at a time rather than skipping steps.

NEW QUESTION # 140
A nurse needs to administer 0.75 liters of IV fluid over 3 hours. What is the flow rate in milliliters per hour?
(1 liter = 1,000 milliliters)
Answer: A
Explanation:
This question tests unit conversion and rate calculation, both of which are essential skills on the NEX Math Section, especially for medication and IV flow problems. First, convert liters to milliliters because flow rates are typically expressed in milliliters per hour. Since 1 liter equals 1,000 milliliters, multiply 0.75 liters by
1,000 to get 750 milliliters. Next, determine the flow rate by dividing the total volume by the total time. The fluid is administered over 3 hours, so divide 750 milliliters by 3 hours. This calculation gives 250 milliliters per hour. Therefore, the correct answer is option C. Option A results from dividing incorrectly, option B reflects underestimation, and option D would be correct only if the volume were larger. NEX exam questions often focus on proper setup of unit conversions before performing calculations. Always convert units first, then divide by time to find a rate.

NEW QUESTION # 141
Review the diagram below of the human eye.
Structure number 1 is necessary in order for the eye to
Answer: A
Explanation:
Structure number 1 in the diagram represents the lens of the eye. The lens plays a crucial role in focusing incoming light onto the retina so that clear images can be formed. It changes shape through a process called accommodation, allowing the eye to focus on objects at varying distances. Protection from debris is mainly the function of the cornea, eyelids, and eyelashes. Regulation of light entering the eye is controlled by the iris, which adjusts the size of the pupil. Picking up light stimuli is the role of rods and cones located in the retina.
Because the lens is responsible for bending and focusing light precisely onto the retina, option A is correct.
The NEX Science exam frequently tests the relationship between eye structures and their functions, particularly focusing mechanisms.

NEW QUESTION # 142
In which biochemical family do starch and glycogen belong?
Answer: A
Explanation:
Starch and glycogen are both polysaccharides, which are complex carbohydrates composed of many glucose units. Starch is the primary storage form of glucose in plants, while glycogen is the storage form of glucose in animals, particularly in the liver and muscles. Carbohydrates serve as a major energy source for cells. Nucleic acids store genetic information, proteins perform structural and enzymatic functions, and lipids are involved in energy storage and membrane structure. The NEX Science exam often tests classification of biomolecules and their functions, making carbohydrates the correct answer.
