Answer: C
Rationale: Fats provide 9 kcal/g, while carbohydrates and proteins provide 4 kcal/g and alcohol provides 7
kcal/g. Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide

distractors, making a clear rationale essential for mastery.
2. What is the primary site for the absorption of most nutrients in the human digestive system?
A. Small Intestine
B. Large Intestine
C. Stomach
D. Esophagus
Answer: A
Rationale: The small intestine, specifically the jejunum and ileum, is where the majority of nutrient absorption
occurs due to its large surface area. Applying this knowledge in clinical settings supports safe, evidence-based
practice and improves patient outcomes. This is an important clinical concept because selecting the correct
answer (A) requires understanding both the pathophysiology and the practical nursing implications.
3. A patient with high blood pressure is advised to follow the DASH diet. Which mineral is
emphasized for its ability to lower blood pressure?

B. Sodium
C. Chloride
D. Iron
Answer: A
Rationale: The DASH diet emphasizes potassium, calcium, and magnesium to help lower blood pressure while
reducing sodium intake. This is an important clinical concept because selecting the correct answer (A) requires

pregnancy. Recognizing this principle allows the nurse to prioritize care, anticipate complications, and provide
accurate patient education. Exam questions often test the ability to distinguish this concept from closely related
distractors, making a clear rationale essential for mastery.
6. Which of the following is a classic symptom of Vitamin C deficiency (Scurvy)?
A. Night blindness
B. Bleeding gums
C. Rickets
D. Osteoporosis
Answer: B
Rationale: Vitamin C is essential for collagen synthesis; its deficiency leads to weak connective tissues and
bleeding gums. Applying this knowledge in clinical settings supports safe, evidence-based practice and
improves patient outcomes. This is an important clinical concept because selecting the correct answer (B)
