CHAPTER 1 — THE STUDY OF ANATOMY AND PHYSIOLOGY
1. A nurse is teaching a newly admitted patient the meaning of homeostasis.
Which statement by the patient indicates correct understanding?
A. “Homeostasis means my body will never change.”
B. “Homeostasis means my internal conditions stay relatively stable.”
C. “Homeostasis means my body temperature must be exactly the same at all
times.”
D. “Homeostasis means I cannot get sick.”
Answer: B.
Rationale: Homeostasis refers to maintaining internal conditions within a
relatively stable range, not absolute unchanging values. Choices A and C are
absolute statements and incorrect; D is false.
2. Which organizational level is directly above the tissue level?
A. Molecule
B. Cell
C. Organ
D. Organism
Answer: C.
Rationale: Levels: molecule → organelle → cell → tissue → organ →
organ system → organism. The organ level is directly above tissue.
3. A patient’s arterial blood gas shows a pH of 7.32. Which term best describes
this condition?
A. Normal
B. Alkalosis
C. Acidosis
D. Hypoxia
Answer: C.
Rationale: Normal pH ~7.35–7.45. pH 7.32 is below normal = acidosis.
Hypoxia relates to oxygen, not pH.
4. In a negative feedback loop that controls body temperature, which
component detects the change?
A. Effector
B. Integrating center
C. Receptor
D. Stimulus
,Created By FutureBright
Answer: C.
Rationale: Receptors detect changes (e.g., thermoreceptors detect
temperature). Integrating center (hypothalamus) compares input and signals
effectors that enact changes.
5. Scenario: A patient’s blood pressure falls. The baroreceptors in the carotid
sinuses sense this and increase sympathetic output to the heart. What role do
the heart and blood vessels play in this feedback loop?
A. Stimulus
B. Receptor
C. Integrating center
D. Effector
Answer: D.
Rationale: Effectors carry out the response (increase heart
rate/vasoconstriction) to restore blood pressure.
6. Which body plane divides the body into left and right portions?
A. Frontal (coronal)
B. Transverse
C. Sagittal
D. Oblique
Answer: C.
Rationale: Sagittal plane divides left/right; frontal divides anterior/posterior;
transverse divides superior/inferior.
7. Which of the following terms correctly describes the location of the wrist
relative to the elbow?
A. Proximal
B. Distal
C. Medial
D. Superior
Answer: B.
Rationale: Distal = farther from trunk or point of origin; wrist is distal to
elbow.
8. During a physical exam, the clinician palpates the epigastric region. Which
organ is most likely to be located there?
A. Spleen
B. Stomach
, Created By FutureBright
C. Cecum
D. Urinary bladder
Answer: B.
Rationale: Epigastric region overlies stomach (superior to umbilical region).
Spleen is left hypochondriac; cecum is right iliac; bladder is suprapubic.
9. Which body cavity contains the heart and lungs?
A. Cranial cavity
B. Thoracic cavity
C. Abdominopelvic cavity
D. Spinal cavity
Answer: B.
Rationale: Thoracic cavity houses lungs and heart (within mediastinum).
Cranial is brain, abdominopelvic holds abdominal and pelvic organs.
10. Which of the following best describes a positive feedback mechanism?
A. It always restores homeostasis.
B. It amplifies an initial change, often moving system away from starting
point.
C. It prevents changes in the internal environment.
D. It is the most common mechanism for long-term control.
Answer: B.
Rationale: Positive feedback amplifies changes (e.g., oxytocin in labor). It
may move the system away from baseline until an external interrupt occurs.
11. A patient is lying face down. What is the correct term for this body position?
A. Supine
B. Prone
C. Lateral
D. Fowler’s
Answer: B.
Rationale: Prone = lying on abdomen (face down). Supine = face up.
12. Which of the following is an example of an anatomic variation among
healthy individuals?
A. Situs inversus (complete reversal of organ positions)
B. Polydactyly (extra fingers) causing dysfunction
C. One kidney smaller than the other but normal function
D. Absence of a lung
