KEY A+ GRADED MOST RECENT!!!
1. Failure to thrive (FTT) is best described as:
A. A specific disease caused by malnutrition
B. A sign of multiple organic and non-organic conditions
C. A genetic disorder affecting growth hormone
D. A condition that only affects premature infants
Rationale: FTT is not a single disease but a clinical manifestation reflecting
inadequate growth from various organic, psychosocial, or mixed causes.
2. Which anthropometric criterion supports the diagnosis of failure to thrive?
A. Weight curve crossing one major percentile line
B. Weight consistently below the 10th percentile
C. Weight curve crossing two or more major percentile lines after achieving a
stable pattern
D. Weight for height greater than 1 SD below the mean
Rationale: A key diagnostic criterion is a decline across two or more major
percentile lines on a standardized growth chart.
, 3. In terms of z-scores, faltering weight is defined as weight-for-length or
BMI-for-age below:
A. −1.65 z-score
B. −1.0 z-score
C. −2.0 z-score
D. −3.0 z-score
Rationale: The AAP/NASPGHAN guideline defines faltering weight as weight-
for-length or BMI-for-age less than −1.65 z-score (approximately the 5th
percentile).
4. For children younger than 2 years, faltering weight includes weight gain
velocity below:
A. −1.0 z-score
B. −2.0 z-score
C. −1.65 z-score
D. −2.5 z-score
Rationale: In children under 2 years, weight gain velocity less than −2 z-score
for age (2.3rd percentile) is a diagnostic criterion.
5. A decline in weight, weight-for-length, or BMI of at least how many z-
scores is diagnostic of faltering weight?
A. 0.5
B. 1.0
C. 1.5
D. 2.0
,Rationale: A decline of ≥1 z-score in weight, weight-for-length, or BMI meets
diagnostic criteria for faltering weight.
6. The most common category of failure to thrive is:
A. Organic causes
B. Non-organic causes
C. Mixed causes
D. Genetic causes
Rationale: Non-organic (psychosocial) causes are the most common category of
FTT.
7. Which of the following is considered a non-organic cause of failure to
thrive?
A. Celiac disease
B. Poverty
C. Cystic fibrosis
D. Hyperthyroidism
Rationale: Poverty is a psychosocial/environmental factor, whereas the others
are organic medical conditions.
8. Child abuse and neglect should be suspected as a cause of FTT when:
A. The child has congenital heart disease
B. The child responds rapidly to nutritional therapy
C. FTT does not respond to appropriate interventions
D. The parents are wealthy
, Rationale: Lack of response to standard nutritional rehabilitation raises concern
for abuse or neglect.
9. Which condition causes FTT due to inadequate absorption?
A. Chronic infection
B. Celiac disease
C. Hyperthyroidism
D. Congenital heart disease
Rationale: Celiac disease impairs intestinal absorption of nutrients.
10.Chronic infection and hyperthyroidism lead to FTT through which
mechanism?
A. Inadequate caloric intake
B. Inadequate absorption
C. Increased metabolism
D. Genetic abnormality
Rationale: Both increase metabolic demand, leading to increased caloric
requirements.
11.When taking a family history for a child with FTT, why is it important to ask
about parents' heights?
A. To diagnose hypothyroidism
B. To rule out constitutional short stature
C. To assess for child neglect
D. To calculate the z-score
