,QUESTION 1
During football practice, a 13-year-old male breaks his humerus. The healthcare
professional is concerned that future growth of the arm will be affected because of
the placement of this break. Based on this concern, the fracture occurred in what
location?
A) Articular cartilage
B) Epiphyseal plate
C) Medullary cavity
D) Diaphysis
E) Periosteum
Correct Answer: B
Rationale: The epiphyseal plate, also known as the growth plate, is the area of
developing cartilage tissue near the ends of long bones in children and adolescents. This
plate is responsible for longitudinal bone growth through endochondral ossification,
where cartilage is gradually replaced by bone tissue. At age 13, the epiphyseal plates are
still active and have not yet fused (a process that typically completes in late adolescence).
Damage to the epiphyseal plate, particularly through a fracture, can disrupt the normal
growth process and potentially lead to limb length discrepancy or angular deformity. The
epiphyseal plate is the weakest point in the growing skeleton and is therefore more
susceptible to injury. The articular cartilage (A) covers the ends of bones at joints and is
not primarily responsible for growth. The medullary cavity (C) is the central cavity of
bone shafts that contains bone marrow. The diaphysis (D) is the shaft of the long bone,
and fractures here can heal without affecting growth because the growth plate is not
involved. The periosteum (E) is the fibrous membrane covering bone surfaces and is
involved in bone growth in width, not length.
QUESTION 2
,What internal structure of the ear is concerned with hearing?
A) Cochlea
B) Auricle
C) Semicircular canals
D) Utricle
E) Tympanic membrane
Correct Answer: A
Rationale: The cochlea is the spiral-shaped, fluid-filled structure in the inner ear that is
responsible for hearing. It contains the organ of Corti, which houses specialized hair cells
that convert mechanical sound vibrations into neural impulses. The cochlea's basilar
membrane vibrates at different frequencies along its length, allowing for the perception
of different pitches. The auricle (B) is the visible external part of the ear that collects
sound waves and directs them into the ear canal. The semicircular canals (C) are three
fluid-filled tubes in the inner ear that are primarily responsible for detecting rotational
movements and maintaining balance and equilibrium. The utricle (D) is a structure in the
vestibular system that detects linear acceleration and head position relative to gravity.
The tympanic membrane (E) is the eardrum, which vibrates in response to sound waves
but is not the primary structure for hearing; rather, it transmits sound to the middle ear
bones. Understanding ear anatomy is essential for nurses and healthcare professionals
who must assess hearing function and identify conditions affecting different ear
structures.
QUESTION 3
What is the primary function of hemoglobin?
A) Transport oxygen
B) Produce blood clots
C) Carry oxygen
, D) Fight infection
E) Regulate blood pressure
Correct Answer: A
Rationale: Hemoglobin is a complex protein molecule found in red blood cells
(erythrocytes) that serves the critical function of transporting oxygen from the lungs to
the body's tissues and organs. Each hemoglobin molecule consists of four protein chains
(two alpha and two beta globin chains) and four heme groups, each containing an iron
atom that can reversibly bind to one oxygen molecule. This allows a single red blood cell
to carry approximately one billion oxygen molecules. While "carry oxygen" (C) is also
technically correct, the more precise primary function is "transport oxygen," which
emphasizes the dynamic process of picking up oxygen in the lungs and releasing it in the
tissues. Hemoglobin also aids in the transport of carbon dioxide (a waste product) from
tissues back to the lungs for exhalation. It does not produce blood clots (B); that function
belongs to platelets and clotting factors. Hemoglobin does not fight infection (D); that is
the role of white blood cells and antibodies. It does not regulate blood pressure (E); that
function involves the cardiovascular system, hormones, and the kidneys. An
understanding of hemoglobin is fundamental for nurses to recognize the signs and
symptoms of anemia and other hemoglobinopathies.
QUESTION 4
Which hormone induces the growth of pubic and axillary hair at puberty?
A) Oxytocin
B) Progesterone
C) Testosterone
D) Prolactin
E) Estrogen
Correct Answer: C
