Expert Rationales
Question 1
A nurse is calculating intake for a patient who consumed 6 ounces of coffee, 4 ounces of
orange juice, and 8 ounces of water. How many milliliters should the nurse record?
A) 360 mL
B) 480 mL
C) 540 mL
D) 600 mL
Answer: C) 540 mL
Rationale: The conversion factor for ounces to milliliters is 1 ounce = 30 mL. Total fluid intake
is calculated by summing all consumed volumes: 6 oz + 4 oz + 8 oz = 18 ounces. Using the
standard conversion, 18 oz × 30 mL/oz = 540 mL. This calculation is essential for accurate
intake and output monitoring, which helps assess fluid balance, renal function, and nutritional
status. Nurses must be proficient in these conversions for clinical documentation and to identify
potential fluid imbalances such as dehydration or fluid overload.

Question 2
Which macronutrient provides 4 kilocalories per gram?
A) Lipids
B) Protein
C) Alcohol
D) Carbohydrates
Answer: D) Carbohydrates
Rationale: Carbohydrates provide 4 kilocalories per gram, making them an efficient energy
source. This energy value is essential knowledge for calculating nutritional needs, particularly
for patients requiring specific caloric intake. Proteins also provide 4 kcal/g, while lipids provide

9 kcal/g, and alcohol provides 7 kcal/g. Understanding these values enables healthcare providers
to design appropriate therapeutic diets, calculate total parenteral nutrition requirements, and
educate patients about energy balance for weight management or disease-specific nutritional
planning.

Question 3
What is the primary function of carbohydrates in the human body?
A) To build and repair tissues
B) To enhance vitamin absorption
C) To provide energy
D) To protect internal organs
Answer: C) To provide energy
Rationale: Carbohydrates serve as the body's preferred and primary energy source. When
consumed, carbohydrates are broken down into glucose, which is absorbed into the bloodstream
and transported to cells throughout the body. Glucose then enters cellular respiration pathways to
produce adenosine triphosphate (ATP), the energy currency for all cellular activities. The brain
and red blood cells are particularly dependent on glucose for energy. Excess carbohydrates can
be stored as glycogen in the liver and muscles or converted to fat for long-term energy reserves.
...
Question 4
1 ounce is equivalent to how many milliliters?
A) 15 mL
B) 20 mL
C) 30 mL
D) 45 mL
Answer: C) 30 mL
Rationale: The standard conversion in healthcare settings is 1 fluid ounce equals approximately
30 milliliters. This conversion is fundamental for accurate medication dosing, nutritional intake
calculations, and fluid balance monitoring. Nurses must memorize this conversion to properly
document patient intake, calculate enteral feeding rates, and ensure accurate recording of all
fluids consumed. Errors in conversion can lead to inaccurate assessment of hydration status,
improper medication administration, and compromised patient safety.
