Chapter 1: Variation and Disease
1. Which of the following best describes the concept of "normal variation" in
human physiology?
A) All individuals maintain identical physiological parameters at all times
B) Physiological parameters fluctuate within a statistically defined range among
healthy individuals
C) Normal variation only applies to psychological characteristics, not physical ones
D) Normal variation is determined solely by genetic factors
Answer: B
Rationale: Normal variation refers to the range of values for physiological
parameters (e.g., blood pressure, heart rate, body temperature) that are
considered healthy. These values differ among individuals based on age, sex,
ethnicity, and environmental factors.
2. A nurse is reviewing laboratory results and notes that a patient's serum
sodium is 138 mEq/L. This value falls within the reference range. What does this
most likely indicate?
A) The patient is free from all disease processes
B) The patient's sodium level is within the statistically normal population range
C) The patient requires immediate intervention
D) The laboratory equipment is malfunctioning
Answer: B
Rationale: Reference ranges are established from population data and represent
the values found in approximately 95% of healthy individuals. A value within this
range suggests statistical normality but does not guarantee the absence of all
disease.
3. Which factor is LEAST likely to contribute to individual variation in
physiological parameters?
, A) Age
B) Biological sex
C) Time of day
D) The patient's blood type
Answer: D
Rationale: Age, sex, and circadian rhythms (time of day) significantly influence
physiological parameters such as hormone levels, metabolic rate, and blood
pressure. Blood type does not directly influence most routine physiological
measurements.
4. Homeostasis is best defined as:
A) The complete absence of physiological change in the body
B) The body's ability to maintain a stable internal environment despite external
changes
C) The process by which the body eliminates all toxins
D) The equal distribution of fluids across all body compartments
Answer: B
Rationale: Homeostasis is the dynamic process by which the body regulates its
internal environment to maintain stability. It involves continuous adjustments
through feedback mechanisms, not a static state.
5. A patient presents with a body temperature of 38.5°C. The nurse recognises
this as a deviation from the normal range. This deviation is most accurately
termed:
A) Homeostasis
B) Physiological adaptation
C) Pathophysiological change
D) Normal circadian variation
Answer: C
Rationale: A temperature of 38.5°C (101.3°F) exceeds the normal range and
represents a pathophysiological change, most commonly associated with infection
