Question 1
Which term refers to animals without backbones?
Correct Answer:
Invertebrates
Explanation:
This question tests how we classify animals by whether they have a backbone. Animals without backbones are called invertebrates. This group includes insects, spiders, snails, worms, and jellyfish, and it makes up the vast majority of animal species. Animals with backbones, by contrast, are vertebrates and include fish, birds, mammals, reptiles, and amphibians. Pathogens are disease-causing agents and don’t describe a group of animals by backbone status, and taxonomy is the science of naming and classifying organisms, not a type of animal. So the best term for animals without backbones is invertebrates because it directly describes the absence of a backbone.
Question 2
Which term describes a colloidal dispersion of a liquid in another liquid?
Correct Answer:
Emulsion
Explanation:
Emulsion describes a colloidal dispersion of a liquid in another immiscible liquid. In these systems, tiny droplets of one liquid are spread throughout the other liquid, such as oil droplets in water (oil-in-water) or water droplets in oil (water-in-oil). Emulsions often need an emulsifier to stay mixed because the liquids don’t naturally blend. This is different from a suspension, which has solid particles floating in a liquid and may settle out, and from a solution, where substances are dissolved at the molecular level with no distinct droplets. While colloid is a broader category, it’s the specific liquid-in-liquid case that’s called an emulsion.
Question 3
Which term is the study of algae?
Correct Answer:
Phycology
Explanation:
Phycology is the study of algae. The word uses phykos, an old term for seaweed or algae, plus -logy, meaning the study of. This field covers the biology, classification, physiology, and ecology of algae—from microscopic green algae to large seaweeds. Other terms refer to different organisms or fields: mycology is the study of fungi, bacteriology is the study of bacteria, and ecology focuses on how organisms interact with each other and their environment. Since the question asks for the term specifically about algae, phycology is the best fit.
Question 4
Where are neutrons located?
Correct Answer:
In the nucleus
Explanation:
Neutrons reside in the atomic nucleus, the dense center of an atom where protons are also found. They’re held there by the strong nuclear force, contributing to the nucleus’s mass and stability. Electrons occupy surrounding space in electron shells, so neutrons aren’t located outside the nucleus or in the electron shells. In the context of a normal atom, neutrons are together with protons in the nucleus; free neutrons can exist outside nuclei in other situations, but not as part of the atom’s structure.
Question 5
The nephron is the functional unit of the kidney.
Correct Answer:
True
Explanation:
The main idea here is that the nephron is the kidney’s functional unit. The nephron is the smallest structure that carries out the kidney’s essential tasks: filtering blood, reabsorbing needed substances, secreting wastes, and forming urine. Each kidney contains about a million nephrons, all working together to process blood and make urine. Because of this, the statement is true. The alternatives suggesting uncertainty or that the fact isn’t stated don’t fit with how kidneys are understood in physiology, and saying it’s false would contradict established anatomy.

Exam overview

About this Exam

The National League for Nursing Nurse Entrance Exam (NLN NEX) is a premier standardized admissions assessment designed to evaluate the academic readiness of prospective nursing students.

Replaced as the modern successor to the legacy PAX exam, the NEX provides nursing educators with a reliable evaluation of a candidate's foundational knowledge before entering a rigorous nursing program.

This exam is tailored specifically for students applying to Licensed Practical Nursing (LPN/LVN), Registered Nursing (RN), and Bachelor of Science in Nursing (BSN) programs across the nation.

By measuring core competencies in communication, mathematical computation, and scientific reasoning, the NLN NEX ensures that candidates possess the critical thinking skills necessary to thrive in nursing school and future clinical environments.

What the Course Entails and Exam Details

Preparing for the NLN NEX involves mastering a comprehensive syllabus spanning three foundational academic subjects: Verbal Ability, Mathematics, and Science.

The exam delivers a total of 163 multiple-choice questions, which include 145 scored items and 18 unscored pretest items used to evaluate new questions for future tests.

Verbal Ability (58 Items)

This section assesses verbal reasoning, vocabulary, and reading comprehension across the 9th to 14th-grade difficulty levels.

The Word Knowledge subsection tests affixes (prefixes, suffixes, and roots), context clues, synonyms, antonyms, and easily confused terms commonly found in medical and academic healthcare texts.

The Reading Comprehension subsection requires students to analyze, interpret, and draw logical conclusions from short informational passages covering health, science, and social topics.

Mathematics (45 Items)

The Mathematics domain covers quantitative reasoning and fundamental computational skills from the 6th-grade level through high school Algebra I.

Key topics include numbers and operations (integers, fractions, decimals, and percentages), algebra (solving basic equations and algebraic manipulations), measurement conversions (metric and standard ratios crucial for dosage calculations), and data interpretation from charts and tables.

Science (60 Items)

As the largest and most critical section for healthcare aspirants, the Science domain tests high-school and introductory college-level knowledge across five core areas.

General Biology covers cellular structure, mitosis and meiosis, genetics, microorganisms, and basic evolution.

Human Anatomy and Physiology focuses heavily on the structure and function of eleven major body systems, including the cardiovascular, respiratory, nervous, musculoskeletal, and immune systems.

Chemistry evaluates understanding of matter properties, atomic structure, chemical bonding, and pH balance, while the General Health section assesses individual health, nutrition, disease prevention, and safety principles.


What to Expect in the Final Exam

The NLN NEX is a computer-based assessment delivered as a Linear-On-The-Fly Test (LOFT), meaning each candidate receives a unique, secure test form aligned with strict content blueprints.

All questions are presented in a multiple-choice format with exactly four answer options per question.

Time Limits and Pace

The total testing duration is exactly 3 hours, divided equally among the three academic domains.

You will be given exactly 60 minutes for Verbal Ability, 60 minutes for Mathematics, and 60 minutes for Science.

Time management is vital; pacing yourself to answer approximately one question per minute ensures you can complete each section without rushing.

Scoring and Passing Requirements

There is no universal "pass" or "fail" grade set by the National League for Nursing; instead, each individual college or university nursing program establishes its own minimum admission score requirements.

Scores are scaled from 0 to 300 for each section, and candidates also receive a national percentile rank that indicates how their performance compares to other nursing applicants nationwide.

Most competitive nursing schools look for composite scores in the 60th to 70th percentile or higher, so checking your specific program’s admissions guidelines is essential.

A major advantage of the NEX scoring model is that there is no penalty for guessing.

Unanswered questions are marked as incorrect, so candidates should strongly be encouraged to answer every single question before time expires.

Strict Testing Rules and Environment

Whether taking the test on-site or remotely, strict security protocols are enforced to maintain exam integrity.

For remotely proctored virtual exams, candidates must sit alone in a quiet, well-lit, walled room at a clean desk or table with all background noise eliminated.

Only one computer monitor is permitted, and headsets, earbuds, smartwatches, cell phones, physical calculators, scratch paper, food, and beverages are strictly prohibited in the immediate testing workspace.


How to Study and Exam Centers

Success on the NLN NEX requires a structured, active study strategy rather than passive reading.

Begin by completing a full-length, timed diagnostic practice test to benchmark your current strengths and identify specific subject areas that require extra attention.

Actionable Study Strategies

Build daily mental stamina by practicing under realistic timed conditions—set a timer for 60 minutes and attempt 50 to 60 questions without taking a break.

Dedicate significant study time to Human Anatomy and Physiology and basic Algebra, as these foundational areas carry immense weight in nursing school admissions.

Utilize active recall methods such as flashcards to memorize common medical root words, chemical formulas, and standard metric-to-household measurement conversions.

After every practice session, carefully review the detailed answer explanations for both correct and incorrect choices to understand the underlying logic of the exam.

Official NLN study bundles, digital practice assessments, and knowledge-check quizzes serve as the most reliable preparation tools because they accurately mirror the actual computer test interface and question difficulty.

Where and How to Take the Exam

The NLN NEX is administered through two convenient, flexible testing modalities scheduled directly via the official NLN student portal.

Candidates can choose to take the exam in-person at an authorized university testing center or on-site at a participating nursing school's computer laboratory.

Alternatively, students can choose virtual remote proctoring (monitored live via services such as Proctor360), allowing you to complete the exam securely from the comfort of your own home.

Registration requires setting up an official account on the NLN examination portal, paying the required testing fee, and selecting a testing date and time that aligns with your nursing school application deadlines.
