Review of 500+ Comprehensive Multichoice Questions
with Solutions and Explanations| Pass Guaranteed
Introduction
This comprehensive study guide contains over 500 multiple-choice questions
designed to prepare students for the UNITEK LVN Term 1 Final Examination. The
questions cover essential nursing concepts including anatomy and physiology,
nursing fundamentals, patient care procedures, medication administration, safety
protocols, and professional nursing practice. Each question is accompanied by four
answer choices with the correct answer clearly identified along with a detailed
rationale to enhance understanding. This resource serves as an invaluable tool for
nursing students preparing for their licensure examination and clinical practice.
Anatomy and Physiology Questions
1. The small intestine contains millions of small finger-like projections called:
A. Rugae
B. Villi
C. Cilia
D. Papillae
Correct Answer: B
Rationale: Villi are small finger-like projections found in the small intestine that
increase the surface area for absorption of nutrients. Rugae are folds in the
stomach, cilia are hair-like structures, and papillae are bumps on the tongue.
2. The small intestine needs bile only a few times each day. Where is bile
stored and concentrated?
A. Liver
B. Pancreas
,C. Gallbladder
D. Duodenum
Correct Answer: C
Rationale: The gallbladder is a pear-shaped organ located under the liver that
stores and concentrates bile produced by the liver. Bile is released into the small
intestine when needed for fat digestion.
3. Which structure of the nephron is primarily responsible for the
reabsorption of water and solutes during urine formation?
A. Loop of Henle
B. Distal convoluted tubule
C. Collecting duct
D. Proximal convoluted tubule
Correct Answer: D
Rationale: The proximal convoluted tubule is the primary site for reabsorption of
water and solutes during urine formation. Approximately 65-70% of filtrate is
reabsorbed here.
4. What is the major regulator of respiratory activities?
A. Oxygen levels (PO2)
B. Carbon dioxide levels (PCO2)
C. Nitrogen levels
D. Hydrogen ion concentration
Correct Answer: B
Rationale: PCO2 (partial pressure of carbon dioxide) is the major regulator of
respiratory activities. Increased CO2 levels stimulate the respiratory center to
increase breathing rate and depth.
5. What event occurs in response to an increase in thoracic volume?
,A. Air is expelled from the lungs
B. Air enters the respiratory passages
C. The diaphragm relaxes
D. The ribs move downward
Correct Answer: B
Rationale: When thoracic volume increases (during inspiration), the pressure
inside the chest decreases, causing air to flow into the respiratory passages and
lungs.
6. Which factor stimulates bones to grow and become stronger?
A. Bed rest
B. Weight-bearing exercise
C. Decreased calcium intake
D. Immobility
Correct Answer: B
Rationale: Weight-bearing exercise stimulates bone growth and strengthens bones
by promoting bone remodeling and increasing bone density.
7. The portion of the brain that controls the basic vital signs of life is the:
A. Cerebellum
B. Cerebrum
C. Medulla oblongata
D. Hypothalamus
Correct Answer: C
Rationale: The medulla oblongata, located in the brainstem, controls basic vital
functions including heart rate, blood pressure, and respiratory rate.
8. Where does the right atrium receive blood from?
, A. Pulmonary veins
B. Aorta
C. Superior and inferior vena cava and coronary sinus
D. Pulmonary artery
Correct Answer: C
Rationale: The right atrium receives deoxygenated blood from the superior vena
cava, inferior vena cava, and coronary sinus before it passes to the right ventricle.
9. Systemic circulation occurs when blood is pumped from the left ventricle to
all parts of the body and returns to the:
A. Left atrium
B. Right atrium
C. Left ventricle
D. Right ventricle
Correct Answer: B
Rationale: In systemic circulation, oxygenated blood is pumped from the left
ventricle to the body and deoxygenated blood returns to the right atrium via the
vena calvae.
10. Oxygenated blood exits through which part of the heart?
A. Pulmonary artery
B. Aorta from the left ventricle
C. Vena cava
D. Right atrium
Correct Answer: B
Rationale: Oxygenated blood exits the heart through the aorta, which receives
blood from the left ventricle.
11. What is the endocrine tissue of the pancreas that contains clusters of alpha
and beta cells?
