NEX Exam Dumps - NLN Nursing Education Program Questions and Answers

This problem tests data interpretation and inference. The graphs show different patterns for each client. Some clients clearly show a decrease in systolic blood pressure after starting the medication, while others show little change or variability. Because not all clients show a decrease, options C and D are incorrect. Option B suggests increased variability, which is not consistently supported across all graphs. Option A accurately summarizes the data by stating thatsomeclients experienced a decrease. On the NEX exam, inference questions often require cautious conclusions rather than absolute statements. Words like “some” and “tended to” are important clues to correct answers.

Respiratory infections are most commonly transmitted through airborne droplets released when an infected person coughs, sneezes, or talks. These droplets may be inhaled directly or land on surfaces where they can be transferred to the respiratory tract. Sexual intercourse and IV drug use are associated with bloodborne or sexually transmitted infections. The fecal-oral route is common for gastrointestinal infections. The NEX Science exam frequently tests routes of transmission as part of infection control and prevention, making coughing the correct and most common route for respiratory infections.

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 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.

Combining disease prevention and health promotion provides the greatest overall impact on reducing cardiovascular disease. Prevention identifies and manages risk factors early, while health promotion encourages long-term lifestyle changes such as healthy eating, exercise, and stress reduction. Education alone increases awareness but may not change behavior. Screening without lifestyle intervention has limited long-term effectiveness. The NEX Science exam emphasizes population health strategies, making integrated prevention and promotion the most effective approach.

This question tests percent decrease, a common NEX topic. First find the amount of decrease: 50 mg − 40 mg = 10 mg. Next divide the decrease by the original amount:

10 ÷ 50 = 0.2.

Convert the decimal to a percent by multiplying by 100:

0.2 × 100 = 20%.

Therefore, the correct answer is B. Option D represents the numerical decrease without considering the original value. Option A and C result from incorrect division. On the NEX exam, percent change problems always use the original value as the denominator.

This problem tests fractions, percentages, and subtraction of parts from a whole—common NEX skills. First calculate the amount spent on decorations:

of $500 equals $62.50. Next calculate the food cost: 25% is equivalent to 0.25, and 0.25 × 500 = $125. Add these two expenses together: $62.50 + $125 = $187.50. This represents the portion of the budget already allocated. To find the remaining budget for venue and entertainment, subtract this amount from the total budget: $500 − $187.50 = $312.50. Therefore, option A is correct. Option B assumes only one category was subtracted. Option C results from incorrect fraction conversion. Option D represents the amount already spent, not the remainder. NEX questions often require careful step-by-step subtraction after converting fractions and percentages correctly.

The passage defines health literacy and explains why it is important for managing health and following medical instructions. Option B best captures the main focus. The other options address topics not discussed. On the NEX exam, purpose questions often begin with a definition followed by explanation, signaling that the passage is meant to inform rather than persuade or compare.

Electrolytes are charged ions that help regulate nerve function, muscle contraction, and fluid balance in the body. Calcium ions (Ca²⁺) are an important electrolyte found in the blood and play a crucial role in muscle contraction, blood clotting, and nerve signaling. Water is not an electrolyte because it does not carry a charge. Iodine is a trace element but not a primary blood electrolyte. Lactase is an enzyme involved in digestion, not an electrolyte. The NEX Science section often includes questions related to human physiology and emphasizes understanding ions and their roles in body function.

The passage explains that herd immunity occurs when a large percentage of the population is vaccinated, which helps protect those who cannot receive vaccines. Option B correctly states this benefit. The passage does not suggest that herd immunity eliminates all diseases or replaces hygiene practices. It also does not mention reducing side effects. On the NEX exam, cause-and-effect questions require identifying the specific outcome discussed rather than making broad assumptions. Herd immunity’s protective effect on vulnerable individuals is the key idea.
