Introduction to Anatomy and Physiology Lesson 6.1 Study Questions Questions
Question 1 of 4
The thoracic cavity is separated from the abdominopelvic cavity by the:
Correct Answer: B
Rationale: The diaphragm separates thoracic (chest) from abdominopelvic cavities, a muscular dome, unlike mediastinum (A, chest divider), abdominal wall, sternum, or nonexistent septum. Anatomically, it regulates breathing, marking cavity boundaries, making E correct.
Question 2 of 4
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 3 of 4
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 4 of 4
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.
