Anatomy and Physiology is the gateway course for every health science and nursing program in the United States — and for most students, it's also their first exposure to the volume and depth of content that college-level science demands. Understanding anatomical structures, physiological mechanisms, and the relationships between body systems is the foundation that every subsequent course — pathophysiology, pharmacology, med-surg — builds directly on.
The OpenStax Anatomy and Physiology textbook by Gordon Betts is unique in nursing education: it's the only major A&P textbook that is completely free online, making it the most widely adopted A&P resource at community colleges, ADN programs, and institutions committed to reducing textbook costs. This test bank gives you the practice questions that turn that free reading into real exam performance.
📘 What is OpenStax? Why does it matter for your A&P course?
OpenStax is a nonprofit educational initiative from Rice University that publishes peer-reviewed, college-level textbooks that are free to access online and low-cost to print. The Anatomy and Physiology textbook by J. Gordon Betts and colleagues is one of OpenStax's most widely adopted titles — used by hundreds of community colleges, ADN programs, and pre-nursing courses across the US. If your professor uses this textbook, your textbook costs $0. This test bank at $9.99 (or $7.99 with MED20) gives you the practice resources to make the most of that free foundation.

3 Real Sample Questions — OpenStax A&P Style
Unit 19 — Cardiovascular (Most NCLEX-Relevant)
During ventricular systole, the mitral valve is closed and the aortic valve is open. Which physiological event directly triggers the closure of the mitral valve at the beginning of systole?
- A. The aortic valve opening creates backpressure that forces the mitral valve closed
- B. The papillary muscles actively pull the mitral valve leaflets closed
- C. Rising ventricular pressure exceeds atrial pressure, pushing the mitral valve leaflets closed
- D. The SA node signal directly causes mitral valve closure through chordae tendineae tension
Correct: C. The mitral (bicuspid) valve closes when left ventricular pressure rises above left atrial pressure at the start of systole — preventing blood backflow into the atrium. The papillary muscles and chordae tendineae prevent valve prolapse (eversion) into the atrium, but the pressure gradient is what triggers closure. Classic OpenStax Unit 19 heart anatomy and physiology question.
Unit 12 — Nervous System
A patient sustains a spinal cord injury at the level of C5. Which functional deficit is most consistent with injury at this level?
- A. Loss of diaphragm function — patient requires permanent mechanical ventilation
- B. Paralysis of the lower extremities and trunk with preserved shoulder and partial arm movement
- C. Complete loss of all motor and sensory function including the arms and diaphragm
- D. Preservation of all upper extremity function with only lower extremity paralysis
Correct: B. C5 injury preserves diaphragm function (innervated primarily by C3–C5 — C5 injury at this level typically preserves phrenic nerve function). The patient has paralysis of trunk and lower extremities but retains shoulder movement (deltoid — C5) and partial elbow flexion. Complete C3 or above injury would eliminate diaphragm function requiring ventilation. Classic spinal cord level function question from OpenStax Unit 12.
Unit 17 — Endocrine System
A nursing student is studying the negative feedback mechanism of the thyroid hormone system. Which sequence correctly describes this feedback loop when circulating thyroid hormone levels are LOW?
- A. Hypothalamus releases TRH → Anterior pituitary releases TSH → Thyroid gland increases T3/T4 production → Rising T3/T4 inhibits TRH and TSH
- B. Posterior pituitary releases TSH → Thyroid releases T3/T4 → T3/T4 stimulates hypothalamus to release more TRH
- C. Low T3/T4 inhibits the hypothalamus from releasing TRH, reducing TSH and further lowering thyroid hormone
- D. Adrenal cortex releases cortisol → stimulates anterior pituitary to increase TSH → thyroid increases T3/T4
Correct: A. The HPT (hypothalamic-pituitary-thyroid) axis is a classic negative feedback loop. Low T3/T4 → hypothalamus releases TRH → anterior pituitary releases TSH → thyroid produces more T3/T4 → rising T3/T4 feeds back to inhibit both hypothalamus and pituitary. This maintains T3/T4 within normal range. Core OpenStax Unit 17 endocrine feedback question — appears on every A&P endocrine exam.
How to Use This Test Bank Alongside the Free OpenStax Textbook
1
Access the free OpenStax textbook online at openstax.org
The full Anatomy and Physiology textbook by Gordon Betts is free at openstax.org/books/anatomy-and-physiology/pages/1-introduction. Read the chapter, then immediately work the corresponding test bank section — this combination of reading + active practice is the most efficient A&P study method.
2
Prioritize cardiovascular, nervous system, and endocrine units
These three systems generate the most NCLEX questions and carry the most weight in subsequent nursing courses. Allocate 40–50 questions per unit for cardiovascular (Units 19–21), nervous system (Units 12–16), and endocrine (Units 17–18) before your exams.
3
Connect anatomy to physiology to clinical application
After each rationale, ask: "How does this anatomy or physiology directly affect what a nurse would observe or do?" A&P knowledge earns the most points — in your course and on NCLEX — when you can connect structure and function to clinical scenarios.
4
Work 30–40 questions per unit within 48 hours of each lecture
Immediate reinforcement dramatically outperforms pre-exam cramming in anatomy and physiology. Content retention is highest in the 48 hours after a lecture — working test bank questions in that window converts lecture content into exam-ready knowledge far more efficiently than saving questions for the night before.
💡 The highest-leverage A&P study habit: For every anatomical structure you study, immediately ask "what is its function?" and "what happens clinically if this structure is damaged or dysfunctional?" This question bridges A&P content to clinical nursing — which is exactly how NCLEX and subsequent nursing course exams frame anatomy questions. The test bank rationales are written to make this connection explicit for every question.

Complete FAQ — Every Question Answered
❓Is this test bank specifically for the OpenStax Anatomy and Physiology textbook by Gordon Betts?
Yes — this test bank is built specifically to match the Anatomy and Physiology 1st Edition published by OpenStax, authored by J. Gordon Betts and colleagues. The questions are organized chapter by chapter to align with the same unit structure as the OpenStax textbook. If your course uses a different A&P textbook (Martini, Saladin, Tortora), this test bank's chapter alignment will differ from your course — check your syllabus before purchasing. If your professor uses OpenStax, this is your test bank.
❓The OpenStax textbook is free — why do I need to pay for a test bank?
The OpenStax textbook is free to read — but reading alone doesn't build the active clinical reasoning that A&P exams and NCLEX test. A test bank gives you exam-style practice questions with clinical scenarios, four-option answers, and rationales that explain the physiological mechanism behind every answer. At $9.99 (or $7.99 with MED20), it's one of the most affordable study investments you can make for a course this foundational — especially when the textbook itself costs $0.
❓How do I receive the test bank after purchasing?
Immediately — as soon as your payment is processed via PayPal, Visa, Mastercard, Apple Pay, or Google Pay, a download link appears on your confirmation page. The same link is emailed to you. No waiting, no approval process. The file is a PDF that opens on any device.
❓Does the MED20 code work on this test bank?
Yes — code MED20 gives 20% off this test bank. Final price after MED20: $7.99 (was $9.99). Enter the code in the discount field at checkout. Valid until October 1st, 2026. This makes it the most affordable test bank on MedTestBank.
❓Can I use this on my phone?
Yes — the test bank is a PDF compatible with all devices. iPhone, Android, iPad, laptop, desktop. Study from your phone on the bus, between labs, or during any free 15-minute window. Fully printable if you prefer studying from paper.
❓Does this test bank help with NCLEX preparation?
Yes — anatomy and physiology is the foundation for NCLEX physiological integrity questions. Understanding how the cardiovascular, respiratory, renal, and neurological systems function at the anatomical and physiological level makes disease process questions on the NCLEX significantly more intuitive. Students who worked through a thorough A&P test bank during their prerequisite course consistently report that NCLEX questions about body system function feel more familiar. The clinical application questions in this test bank are written specifically to build that connection.
❓What if my program uses Martini A&P instead of OpenStax?
If your program uses the Martini Fundamentals of Anatomy & Physiology 12th Edition, the Martini A&P 12th Edition test bank is available on MedTestBank at $17.99 (or $14.39 with MED20). Always buy the test bank that matches your required textbook — chapter alignment to your course is the most important factor in exam preparation effectiveness.
❓How many questions should I do per day to prepare for A&P exams?
For A&P: 30–40 questions per chapter or unit within 48 hours of each lecture. For a comprehensive exam covering multiple systems, aim for 100–150 questions in the week before the exam — focused on the specific units covered. Always read every rationale — in anatomy and physiology, understanding the mechanism is more valuable than just knowing the correct answer, because A&P exam questions are written to test application and reasoning, not bare memorization.
❓What if I lose my download link?
Contact MedTestBank support at support@medtestbank.com or call +1 (541) 573-1844 with your order details. Your download link will be resent promptly. Your purchase is permanent — you never lose access to what you bought.
❓Is there a test bank for the Martini A&P textbook on MedTestBank?
Yes — the Martini Fundamentals of Anatomy & Physiology 12th Edition test bank is available separately on MedTestBank. If your program uses Martini instead of OpenStax, browse the full catalog at medtestbank.com/collections/all to find the right match for your textbook.
