1. A dietetic technician is measuring a patient’s height in the
supine position. The patient cannot stand due to a spinal cord
injury. Which equipment is most appropriate?
A) Stadiometer
B) Tape measure with a sliding bar
C) Knee-height caliper
D) Measuring tape and a straight edge
Answer: C – Knee-height caliper is used for estimating height in
non-ambulatory individuals.
Rationale: Knee height equations are validated for recumbent
,Page 2 of 143
patients. A stadiometer requires standing. Tape measure alone is
insufficient without a formula.
2. The body mass index (BMI) of a patient is calculated as 31
kg/m². This falls into which category?
A) Normal weight
B) Overweight
C) Obesity Class I
D) Obesity Class II
Answer: C – Obesity Class I is BMI 30.0–34.9 kg/m².
Rationale: Normal 18.5–24.9, Overweight 25–29.9, Obesity I
30–34.9, Obesity II 35–39.9, Obesity III ≥40.
3. A patient’s serum albumin level is 2.8 g/dL (normal 3.5–
5.0). This finding is most consistent with:
A) Adequate protein status
,Page 3 of 143
B) Acute inflammation with short-term protein depletion
C) Long-term protein-energy malnutrition or chronic illness
D) Overhydration
Answer: C – Low albumin indicates chronic protein depletion
(half-life ~20 days).
Rationale: Prealbumin (half-life 2-3 days) is a better indicator of
acute changes. Albumin is an acute phase reactant, so
inflammation can also lower it.
4. Which laboratory value is the most sensitive indicator of
recent dietary protein intake?
A) Serum albumin
B) Serum prealbumin (transthyretin)
C) Blood urea nitrogen (BUN)
D) Hemoglobin
, Page 4 of 143
Answer: B – Prealbumin has a short half-life (2-3 days),
reflecting recent protein intake and turnover.
Rationale: Albumin is longer-term. BUN can be affected by
hydration and renal function. Hemoglobin reflects iron status, not
protein.
5. A patient’s hemoglobin is 9.5 g/dL (normal 13.5–17.5 for
males, 12.0–15.5 for females). This indicates:
A) Iron deficiency anemia
B) Polycythemia
C) Normal status
D) Hemoconcentration
Answer: A – Low hemoglobin suggests anemia, often due to iron
deficiency, but also B12 or folate deficiency.
Rationale: The DTR should request additional labs (MCV, ferritin,
B12, folate) to determine etiology.
