NLN Nursing Entrance Exam (Math, Science and Verbal) Sample Questions (Q69-Q74):

NEW QUESTION # 69
Reading Comprehension
Passage:
Adequate hydration is essential for maintaining normal body functions. Water helps regulate body temperature, transports nutrients, and removes waste products. Even mild dehydration can cause fatigue, headaches, and reduced concentration. Healthcare providers often emphasize proper fluid intake, especially for older adults, because the sensation of thirst decreases with age.
Which of the following is the main idea of the passage?

Answer: A

Explanation:
This question asks for themain idea, which is the central message of the passage. The passage discusses several roles of water in the body, including temperature regulation, nutrient transport, and waste removal. It also highlights the effects of dehydration and the importance of monitoring fluid intake, particularly in older adults. All these details support one central idea: hydration is vital for maintaining overall health and proper body function. Option C correctly summarizes this main point. Option A is incorrect because the passage actually suggests older adults are at increased risk of dehydration. Option B contradicts the passage, which emphasizes water's importance. Option D is incorrect because the passage notes that thirst may decrease with age and is not the only indicator. On the NEX exam, main-idea questions often require recognizing repeated themes across the passage rather than focusing on one detail.

NEW QUESTION # 70
The mean and standard deviation (SD) of the heights (in centimeters) of four groups of teenage boys are shown below:

Based on this information, which group has the least variability in height?

Answer: A

Explanation:
This question tests understanding of standard deviation as a measure of variability. The group with thesmallest standard deviation has the least variability. Comparing the values, Group 3 has the smallest SD at 6.9.
Therefore, option D is correct. The mean does not affect variability; only the SD matters in this comparison.
The NEX often includes questions where students must interpret statistical summaries rather than perform calculations. Remember that lower SD values indicate data points are more closely clustered around the mean.


NEW QUESTION # 71
Twenty daily systolic blood pressure measurements are shown in the graph. The red line indicates when a patient stopped taking their blood pressure medication.

Estimate the patient's average increase in blood pressure from the first set of 10 measurements to the second set of 10 measurements.

Answer: B

Explanation:
This problem tests estimation and interpretation of scatter plots. The first 10 measurements (before the red line) cluster around an average of approximately 140 mmHg. The second set of 10 measurements (after the red line) cluster around approximately 170 mmHg. To estimate the increase, subtract the earlier average from the later average: 170 # 140 = 30 points. Therefore, option C is correct. Options A and D represent total values rather than the change between averages. Option B overestimates the difference. On the NEX, estimation questions do not require exact calculations; instead, you must identify reasonable average values from visual data and compare them correctly.


NEW QUESTION # 72
Prepared bottles contain 120 milliliters (mL) of infant formula. An infant drinksbottle every 2 hours for each of their 6 daytime feedings.
Given 1 ounce = 30 mL, how many ounces did the infant drink?

Answer: B

Explanation:
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 ร— 6 = 360 mL. Convert milliliters to ounces using the given conversion: 360 รท 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.

NEW QUESTION # 73
Which of the following structures is found only in bacterial cells, not in plant or animal cells?

Answer: A

Explanation:
Bacterial cells are classified as prokaryotic cells, meaning they lack a membrane-bound nucleus. Instead of a nucleus, bacteria contain their genetic material in a region called the nucleoid. The nucleoid is not surrounded by a membrane and is unique to prokaryotic cells. In contrast, plant and animal cells are eukaryotic and store their DNA inside a true nucleus. Cell membranes, ribosomes, and DNA are found in all living cells, including bacteria, plants, and animals. Ribosomes in bacteria are smaller than those in eukaryotic cells, but they serve the same function of protein synthesis. Because the nucleoid region is exclusive to bacteria and other prokaryotes, option C is the correct answer. The NEX Science section frequently tests differences between prokaryotic and eukaryotic cells, making this an important concept to master.
