Introduction to Anatomy and Physiology Lesson 6.1 Study Questions Questions
Question 1 of 5
The ventral cavity comprises all of the following body cavities except the:
Correct Answer: A
Rationale: The ventral cavity (front) includes pleural (B, lungs), thoracic, pelvic, and abdominal , but not spinal (A, dorsal, with cranial). Anatomically, ventral splits into thoracic and abdominopelvic; spinal lies posterior, protecting the cord, making A the exception.
Question 2 of 5
A lung is located within the:
Correct Answer: B
Rationale: Lungs are in thoracic (chest), pleural (lung-specific), and ventral (anterior) cavities, not mediastinal (A, central), peritoneal (C, abdominal), or pericardial (D, heart). Anatomically, pleural cavities within thoracic (ventral subdivision) encase lungs, aligning with respiratory structure, confirming B.
Question 3 of 5
The nurse is to position a client in standard anatomical position. What is the best description of the standard anatomical position?
Correct Answer: A
Rationale: Standard anatomical position is standing, arms at sides, palms forward (supinated), per option AA. Lying , sitting (C, D) deviate prone or seated alters orientation. Anatomically, this posture standardizes directional terms (e.g., anterior), ensuring consistency in medical descriptions like the heart anterior to the spine making A the best description.
Question 4 of 5
Deoxyribonucleic acid (DNA), which is present in every human being, has which of the following as its main purpose?
Correct Answer: C
Rationale: DNA's main purpose is transmitting genetic material , per options C6-C9, passing genes to offspring via gametes. Transcription and translation are steps in protein synthesis, division control a subset. Anatomically, DNA in the nucleus encodes heredity e.g., eye color inheritance making C its primary role.
Question 5 of 5
When discussing tissue repair with a client following an injury, the nurse explains that the correct sequence of events for tissue repair includes which of the following?
Correct Answer: D
Rationale: Tissue repair follows inflammation (swelling), organization (clot formation), regeneration (new tissue) , per options AC-A6. Anatomically, inflammation recruits immune cells, organization forms granulation tissue, then regeneration heals e.g., skin repair after a cut. Other sequences (A-C) misorder this physiological process, confirming D.
