WGU D313 Anatomy and Physiology Objective Assessment 2025 | Up-
to-Date Exam Questions with Detailed Answers


Question 1:
A nurse is teaching a patient about the structure of the heart. Which of
the following statements should the nurse include?
A) The right atrium pumps blood to the lungs.
B) The left ventricle pumps oxygenated blood to the body.
C) The left atrium receives deoxygenated blood from the body.
D) The right ventricle pumps oxygenated blood to the body.
Answer: B) The left ventricle pumps oxygenated blood to the body.
Rationale: The left ventricle pumps oxygenated blood into the aorta
and to the rest of the body. The right atrium receives deoxygenated
blood from the body, and the right ventricle pumps deoxygenated blood
to the lungs for oxygenation. The left atrium receives oxygenated blood
from the lungs.


Question 2:
Which of the following structures is responsible for producing red blood
cells in adults?
A) Liver
B) Spleen
C) Bone marrow
D) Kidneys
Answer: C) Bone marrow
Rationale: In adults, the bone marrow is responsible for producing red
blood cells through a process called erythropoiesis. The liver and spleen

,may contribute to red blood cell production in fetal development but
not after birth. The kidneys produce erythropoietin, which stimulates
red blood cell production.


Question 3:
A nurse is assessing a patient’s respiratory system. Which of the
following is a normal finding during auscultation of the lungs?
A) Crackles in the lower lobes
B) Dullness over the lung tissue
C) Clear breath sounds throughout
D) Wheezing in the upper lobes
Answer: C) Clear breath sounds throughout
Rationale: Normal lung sounds are clear and free of abnormal sounds
such as crackles, wheezes, or dullness. Crackles indicate fluid in the
lungs, dullness may indicate consolidation or pleural effusion, and
wheezing is indicative of narrowing of the airways, often seen in
asthma.


Question 4:
Which of the following bones is part of the axial skeleton?
A) Clavicle
B) Femur
C) Sternum
D) Scapula
Answer: C) Sternum

,Rationale: The axial skeleton includes the skull, vertebral column, and
rib cage (including the sternum). The clavicle, femur, and scapula are
part of the appendicular skeleton.


Question 5:
The primary function of the kidneys is to:
A) Filter and remove waste products from the blood.
B) Produce insulin for the regulation of blood glucose.
C) Regulate heart rate and blood pressure.
D) Stimulate red blood cell production.
Answer: A) Filter and remove waste products from the blood.
Rationale: The kidneys filter the blood to remove waste products and
excess substances, maintaining fluid and electrolyte balance. The
pancreas is responsible for insulin production, the cardiovascular
system regulates heart rate and blood pressure, and the kidneys
produce erythropoietin, which stimulates red blood cell production.


Question 6:
A nurse is caring for a patient with an autoimmune disease that affects
the myelin sheath of neurons. Which of the following conditions is most
likely?
A) Parkinson’s disease
B) Multiple sclerosis
C) Alzheimer’s disease
D) Guillain-Barré syndrome
Answer: B) Multiple sclerosis

, Rationale: Multiple sclerosis (MS) is an autoimmune disease that
attacks the myelin sheath of neurons, leading to communication
problems between the brain and the body. Parkinson's disease involves
the loss of dopamine-producing neurons, Alzheimer's is characterized
by neurodegeneration, and Guillain-Barré syndrome is an autoimmune
disorder that affects peripheral nerves.


Question 7:
Which of the following is the function of the parathyroid glands?
A) Regulation of blood calcium levels
B) Regulation of blood glucose levels
C) Regulation of metabolic rate
D) Regulation of reproductive hormones
Answer: A) Regulation of blood calcium levels
Rationale: The parathyroid glands secrete parathyroid hormone (PTH),
which regulates calcium levels in the blood by increasing calcium
reabsorption from the bones, kidneys, and intestines. The pancreas
regulates blood glucose, the thyroid regulates metabolism, and the
ovaries/testes regulate reproductive hormones.


Question 8:
Which of the following is the primary function of the large intestine?
A) Digestion of proteins
B) Absorption of nutrients
C) Absorption of water and electrolytes
D) Production of bile
Answer: C) Absorption of water and electrolytes
