# COMPREHENSIVE CLINICAL
REASONING EXAMINATION
## Pediatric, Adolescent, and
Mental Health: A Primary Care
Perspective
### Question 1
Samantha Graves, an 18-month-old female, presents with vomiting and diarrhea for 36 hours. Her
mother reports decreased urine output and dry diapers. Which finding indicates severe dehydration?
,A. Sunken fontanel
B. Dry mucous membranes
C. Capillary refill of 3 seconds
D. Lethargy
💫RATIONALE✔️✔️: Lethargy is a sign of severe dehydration, indicating significant fluid loss and
hypovolemia. Sunken fontanel, dry mucous membranes, and delayed capillary refill are also signs of
dehydration but may be present in moderate dehydration. Lethargy indicates that the child is at risk for
hypovolemic shock and requires immediate intervention, including intravenous fluids if oral rehydration
is not tolerated.
💫ANSWER✔️✔️: D. Lethargy

### Question 2
Samantha Graves' weight is 9 kg, and her pre-illness weight was 9.8 kg. What percentage of weight loss
has occurred?
A. 4%
B. 6%
C. 8%
D. 10%
💫RATIONALE✔️✔️: Weight loss is calculated as (pre-illness weight - current weight) / pre-illness
weight × 100. (9.8 kg - 9 kg) / 9.8 kg = 0.0816 × 100 = 8.16%. This indicates moderate dehydration (6-10%
,weight loss). Severe dehydration is >10% weight loss. Accurate weight measurement is the most reliable
indicator of dehydration in children.
💫ANSWER✔️✔️: C. 8%

### Question 3
Samantha Graves is receiving oral rehydration solution. Her mother asks how much to give. Which
instruction is correct?
A. Give unlimited amounts as tolerated
B. Give 50-100 mL/kg over 4 hours
C. Give 150 mL/kg over 4 hours
D. Give small amounts frequently
💫RATIONALE✔️✔️: For children with mild to moderate dehydration, the recommended approach is
50-100 mL/kg of oral rehydration solution over 4 hours. This replaces fluid deficits while preventing
overload. Small, frequent amounts are better tolerated. Unlimited amounts may lead to vomiting, and
150 mL/kg is for more severe dehydration.
💫ANSWER✔️✔️: B. Give 50-100 mL/kg over 4 hours
---
### Question 4
, Samantha Graves is tolerating oral rehydration solution. Her mother asks about returning to a normal
diet. Which response is correct?
A. "Resume a normal diet immediately."
B. "Advance to a bland diet and then resume normal diet."
C. "Continue oral rehydration solution only."
D. "Start a clear liquid diet and advance as tolerated."
💫RATIONALE✔️✔️: After rehydration, patients can be advanced to a normal diet. Early feeding is
encouraged in children with diarrhea. The "BRAT" diet (bananas, rice, applesauce, toast) is no longer
recommended exclusively. A normal diet provides adequate nutrition and may help reduce the duration
of diarrhea.
💫ANSWER✔️✔️: A. "Resume a normal diet immediately."
---
### Question 5
Samantha Graves' mother asks about preventing dehydration in the future. Which instruction is most
important?
A. "Continue breastfeeding or formula on demand."
B. "Give oral rehydration solution at the first sign of diarrhea."
C. "Avoid giving sugary drinks during diarrhea."
D. "All of the above."
