NEX Exam Dumps - Nursing Entrance Exam (Math, Science and Verbal)

This question assesses fraction-to-percent conversion. Start by converting the fractionto a decimal. Divide 5 by 8:

5 ÷ 8 = 0.625.

To convert a decimal to a percent, multiply by 100:

0.625 × 100 = 62.5%.

Therefore, the correct answer is C. The other options represent incorrect conversions: 37.5% equals, 22.5% is not a standard eighth fraction, and 40% equals. On the NEX exam, knowing common fraction-percent equivalents (such as 1/8 = 12.5%) can significantly reduce calculation time and improve accuracy.

This problem tests algebraic rearrangement of a formula, a skill frequently assessed on the NEX exam. The goal is to isolate the variable. Starting with the equation, notice thatis multiplied by. To solve for, divide both sides of the equation by. Doing so cancelson the right side, leavingalone. The resulting equation is. This corresponds to option B. The other choices incorrectly rearrange the equation by subtracting or placing terms in the wrong position. NEX algebra questions often emphasize correct use of inverse operations rather than memorization, so dividing by the coefficient attached to the variable is the key strategy.

This problem tests fraction addition and subtraction within a real-world nutrition scenario, which is typical of the NEX Math Section. First, recognize that all calorie fractions must total 1 (or the whole). The client getsfrom fats andfrom proteins. To combine these fractions, find a common denominator. The least common denominator of 5 and 4 is 20. Convert the fractions:and. Add them together:. This represents the portion of calories from fats and proteins combined. To find the remainder from carbohydrates, subtract from 1:

Therefore, the correct answer is B. This type of problem reinforces careful fraction operations and understanding of “remainder” language on the NEX exam.

This question assesses understanding of the median, which is the middle value when data are ordered from least to greatest. First, list the refunds in ascending order:

$500, $500, $857, $1,500, $2,500, $3,000, $6,753.

There are seven values total, so the median is the fourth value in the ordered list. The fourth value is $1,500. Therefore, option D is correct. Option B represents the mode (most frequent value), not the median. Options A and C are averages or midpoints that do not correspond to the true median position. On the NEX exam, students are frequently tested on distinguishing mean, median, and mode, so remembering that the median is strictly positional—not calculated—is essential.

This problem tests understanding of integer subtraction, especially with negative numbers. On the number line, −3 is already below zero. Subtracting 7 means moving seven more units to the left. Starting at −3 and moving left seven spaces results in −10. Another way to think about this is to rewrite the problem as adding a negative number: −3 − 7 is the same as −3 + (−7). When adding two negative numbers, you add their absolute values and keep the negative sign. The absolute values of −3 and −7 are 3 and 7, and 3 + 7 = 10, so the result is −10. Option A is therefore correct. Option B is a common mistake when students subtract absolute values incorrectly. Options C and D are positive and would only occur if the signs were misunderstood. The NEX Math Section frequently includes integer operations to assess number sense and sign awareness.

This question tests interpretation of scatter plots and correlation. In the graph, the horizontal axis represents hours studied, and the vertical axis represents test scores. As the points move from left to right (indicating more hours studied), the points also tend to move upward (indicating higher test scores). This shows a positive relationship between the two variables. While not every point follows a perfect line, the overall trend clearly indicates that students who studied more hours generally achieved higher test scores. Option B correctly describes this positive correlation. Option A is incorrect because scores are not highest when no studying occurs. Option C is incorrect because there is a visible relationship. Option D describes a negative relationship, which is not shown. On the NEX exam, scatter plots are often used to test understanding of trends rather than exact values, so identifying the overall direction of the data is key.

This is a percentage complement problem. If 7% of children have high cholesterol, then the remaining percentage with normal cholesterol is 100% − 7% = 93%. Convert 93% to a decimal by moving the decimal point two places to the left: 0.93. Multiply this decimal by the total number of children sampled: 0.93 × 120,000 = 111,600. Therefore, approximately 111,600 children would have normal cholesterol levels, making option D correct. Option A incorrectly calculates 7% instead of the complement. Option C represents 70%, not 93%. Option B is close but incorrect due to rounding. NEX math questions often assess whether students understand that “normal” refers to the remainder after subtracting the affected group.

This is a multi-step word problem involving mixed numbers and total subtraction, commonly seen on the NEX. First calculate Nurse A’s total hours:. Multiply by 5 days:hours. Next, calculate Nurse B’s total hours:. Multiply by 4 days:hours. Now add the hours worked by Nurses A and B:

41.25 + 42 = 83.25 hours (or).

Subtract this from the total combined hours:

130 − 83.25 = 46.75 hours.

Convert 0.75 to a fraction:.

So Nurse C workedhours, making option D correct. The NEX often tests accurate step-by-step calculation with workplace scenarios.
