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

The range of a data set is calculated by subtracting the lowest value from the highest value. From the graph, the lowest systolic blood pressure reading appears to be about 125 mmHg, while the highest reading is about 185 mmHg. Subtracting gives: 185 − 125 = 60. Therefore, option B is correct. Option C represents a single high reading rather than a range. Options A and D underestimate the difference. NEX questions involving range require careful identification of extreme values on graphs, so it is important to examine the entire data set, not just the most common values.

This question tests interpretation of a line graph, a common NEX skill. To answer, focus on the infant whose weight increases the slowest, becauseallinfants must reach at least 30 pounds. By examining the graph, Infant A has the lowest growth curve and reaches 30 pounds later than the others. Tracing horizontally from 30 pounds to Infant A’s line and then down to the x-axis shows that this occurs at approximately 25 weeks. Although some infants reach 30 pounds earlier, the question asks whenallinfants reach that weight, which is determined by the slowest-growing infant. Therefore, option D is correct. The NEX often includes graph-based questions that require identifying minimums or maximums across multiple data sets, so it is important to carefully read qualifiers like “all,” “at least,” or “no more than.”

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.

This is a multi-step dosage and unit-conversion problem. Each bottle contains 120 mL, and the infant drinks half a bottle per feeding. Half of 120 mL is 60 mL. The infant has 6 feedings, so total intake is 60 × 6 = 360 mL. Convert milliliters to ounces using the given conversion: 360 ÷ 30 = 12 ounces. Therefore, option C is correct. Option D represents milliliters, not ounces. Option B incorrectly doubles the intake. The NEX frequently includes pediatric feeding and medication scenarios requiring careful tracking of totals and unit conversions.

This problem requires comparing fractions, percentages, and decimals by converting them to the same form. Convert each score to a decimal. Student A: 19 ÷ 26 ≈ 0.731. Student B: 75 ÷ 100 = 0.75. Student C: 71% = 0.71. Student D: already given as 0.719. Comparing these values, 0.75 is the highest. Therefore, Student B scored the highest. Option D (0.719) is close but still lower than 0.75. The NEX frequently tests comparison skills across different numerical formats, so converting everything to decimals is the safest approach.

This problem involves currency conversion. The exchange rate states that $1 equals €1.2. To convert euros to dollars, divide the euro amount by 1.2. Set up the calculation: €120 ÷ 1.2 = $100. Therefore, the cost per night in US dollars is $100. Option C is correct. Option B incorrectly multiplies instead of dividing. Options A and D fail to account for the exchange rate. NEX math problems involving currency emphasize understanding the direction of conversion and selecting the correct operation.

This problem involves solving a linear equation with fractions. First convert the mixed numberto an improper fraction or decimal.

Addto both sides to isolate the term with x:

Now divide both sides by 3:

Therefore, option D is correct. The NEX exam often includes equations with fractions, so converting to improper fractions early helps simplify the process.

This question tests calculation of the mean. First, add all the infant weights:

8.5 + 11 + 7 + 5 + 7 + 4.5 + 9 + 8 = 60 pounds.

Next, divide the total by the number of infants: 60 ÷ 8 = 7.5? Recheck carefully: 60 ÷ 8 = 7.5, but reviewing the answer choices and recalculating the sum more carefully:

8.5 + 11 = 19.5

19.5 + 7 = 26.5

26.5 + 5 = 31.5

31.5 + 7 = 38.5

38.5 + 4.5 = 43

43 + 9 = 52

52 + 8 = 60

60 ÷ 8 = 7.5, which corresponds to option C.

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.

The passage states that regular exercise strengthens the heart muscle and increases endurance. Option B is therefore correct. The remaining options are not mentioned. The NEX exam frequently includes health-related passages that test recognition of stated benefits.
