Which diagnostic tool is used to identify children who may have an infection or inflammatory process?

A.

Arterial blood gas analysis

B.

Gastric lavage

C.

Erythrocyte sedimentation rate (ESR)

D.

Blood culture

Answer and Explanation

The Correct Answer is C

A. Arterial blood gas analysis evaluates oxygenation, ventilation, and acid-base balance, but it does not indicate infection or inflammation.
B. Gastric lavage is used to remove ingested substances from the stomach, not to detect infection or inflammatory processes.
C. Erythrocyte sedimentation rate (ESR) is a nonspecific test that measures the rate at which red blood cells settle in a tube over a specific time. An elevated ESR can indicate the presence of inflammation or infection in the body.
D. Blood cultures are used to identify the specific pathogen causing an infection but do not measure the general presence of an inflammatory process.

Correct Answer is ["6"]

Explanation

Step 1: Calculate total carbohydrate intake

  • 1 apple = 15 g
  • 8 oz milk = 12 g
  • Bowl of cereal = 48 g
  • 2 pieces of toast = 15 g

Total carbohydrates:
15 + 12 + 48 + 15 = 90 g

Step 2: Determine insulin dose

Prescription: 1 unit per 15 g carbohydrate

Insulin dose = 90 ÷ 15 = 6 units

Final Answer: 6 units

Correct Answer is D

Explanation

A. Complex carbohydrates take longer to digest and raise blood glucose more slowly, which is not ideal for immediate treatment of mild hypoglycemia.
B. Glucagon is reserved for severe hypoglycemia when the child is unconscious or unable to take oral carbohydrates. The child in this scenario is alert and able to eat.
C. Administering insulin would further lower blood glucose and worsen hypoglycemia; this is contraindicated.
D. Giving 10 to 15 g of a simple carbohydrate (e.g., juice, glucose tablets) provides rapid absorption and quick correction of mild hypoglycemia. After 15 minutes, blood glucose should be rechecked and a complex carbohydrate snack may follow to maintain stability.
