NURS 265 PRACTICE TEST QUESTIONS WITH
DETAILED RATIONALES 2026
> pain tolerance? Answer:the maximum level of pain that a person is able
to tolerate
> acute pain? Answer:rapid in onset, varies in intensity and duration,
protective in nature
> chronic pain? Answer:pain that may be limited, intermittent, or persistent
but that lasts beyond the normal healing period
> physiological measures that indicate pain? Answer:increased blood
pressure and pulse
> meaning of healing? Answer:mending and getting better from disease
> 6 classes of nutrients? Answer:supply energy: carbs, proteins, lipids
regulate body processes: vitamins, minerals, water
> carbs? Answer:-sugars and starches
-organic compounds composed of carbon, hydrogen, and oxygen
-lactose is an animal source
-most abundant and least expensive
-classified as simple or complex sugars
-converted to glucose for transport through blood
-50-100g needed daily to prevent ketosis
> protein? Answer:-required for formation of all body structures
-based on amino acid composition
-animal proteins are complete, plant proteins are incomplete
-RDA for adults is 0.8g/kg
> fats? Answer:-insoluble in water and blood
-composed of carbon, hydrogen, and oxygen
- 95% of lipids in diet are triglycerides
-most animal fats are saturated
, -most vegetable fats are unsaturated
-digestion occurs largely in small intestine
-most concentrated source of energy in diet
-RDA not established, 20-35% total calorie intake
> Vitamins? Answer:-organic compounds needed by the body in small
amounts
-most are active in form of coenzymes
-classified as water soluble or fat soluble
-absorbed through intestinal wall (small intestine) directly into bloodstream
-needed for metablolism
> minerals? Answer:-inorganic elements found in all body fluids and tissues
-some function to provide structure in the body, others help regulate body
processes
-contained in ash that remains after digestion
-macrominerals include calcium, phosphorus, magnesium
-microminerals include iron, zinc, manganese, and iodine
> water? Answer:-accounts for between 50% and 60% of adults total
weight
-2/3 of body water is contained within the cells (ICF)
-the remainder of body water is extracellular fluid, body fluids
-acts as solvent, aids digestion
> pronation? Answer:face down; laying on your stomach
> supination? Answer:face up; laying on your back (spine)
> inversion? Answer:turning foot inward
> eversion? Answer:turning foot outward
> afferent nervous system conveys info to the? Answer:CNS; going to your
brain
> efferent? Answer:creates effect and goes to body part from brain
> the efferent system conveys via? Answer:somatic nervous system
