1 Introduction
This study guide is designed for the Navy Hospital Corpsman HCB Test 7 2025, focusing
on musculoskeletal and dermatological concepts critical for Corpsmen. It includes 100
carefully crafted questions with verified answers and detailed explanations, presented
clearly to enhance understanding and eliminate unnecessary complexity. Questions are
highlighted in very dark red for emphasis and effective study.
2 Questions and Answers with Explanations
Question 1: What is the term for the movement of a limb away from the
body’s midline?
Answer: Abduction
Explanation: Abduction describes the motion of a limb moving laterally
away from the body’s midline, such as raising an arm outward. This is
a fundamental concept in musculoskeletal anatomy, essential for assessing
joint mobility during physical examinations.
Question 2: What term describes the movement of a limb toward the body’s
midline?
Answer: Adduction
Explanation: Adduction involves moving a limb closer to the midline,
like lowering an arm to the side. Corpsmen use this term to evaluate joint
function and identify restrictions in movement due to injury or disease.
Question 3: What is a fracture where the bone breaks into multiple frag-
ments?
Answer: Comminuted fracture
Explanation: A comminuted fracture occurs when a bone shatters into
three or more pieces, often due to high-impact trauma. Corpsmen stabilize
these injuries with splints to prevent further damage and refer for surgical
evaluation.
Question 4: What is the medical term for a joint where two bones meet?
Answer: Articulation
Explanation: An articulation, or joint, is the point of connection between
two bones, enabling movement or stability (e.g., the knee). Corpsmen
assess articulations to diagnose joint injuries or deformities.
Question 5: What term describes the wasting of muscle tissue due to disuse
or disease?
Answer: Atrophy
Explanation: Atrophy is the reduction in muscle mass or function due to
factors like immobilization or neurological conditions. Corpsmen monitor
atrophy during recovery to recommend physical therapy or interventions.
