Calculate a bolus rate (mL/kg/hour) to be given to a severely dehydrated child with diarrhea weighing 23 kg over 60 minutes. The pulse will be checked after the bolus.
The Correct Answer is ["20"]
Calculation Steps
Step 1: Determine the child’s weight in kg.
- Weight = 23 kg
Step 2: Determine the time period in hours.
- Time = 60 minutes = 1 hour
Step 3: Calculate the bolus rate in mL/kg/hour.
- Bolus rate (mL/kg/hour) = Total volume (mL) ÷ (Weight × Time)
Step 4: Assume a standard bolus volume for severe dehydration, which is typically 20 mL/kg.
- Total volume = 20 mL/kg × 23 kg = 460 mL
Step 5: Calculate the bolus rate.
- Bolus rate (mL/kg/hour) = 460 mL ÷ (23 kg × 1 hour) = 20 mL/kg/hour
Result
The bolus rate to be given to the severely dehydrated child is 20 mL/kg/hour.

Correct Answer is ["A","B","C"]
Explanation
The correct answers are a) Use a straw to administer the medication, b) Give the medication with vitamin C, and c) It is best to give the medication with food.
Choice A reason:
Using a straw to administer ferrous sulfate is recommended to prevent staining of the teeth. Ferrous sulfate, especially in liquid form, can cause discoloration of the teeth if it comes into direct contact with them. By using a straw, the medication bypasses the teeth, reducing the risk of staining.
Choice B reason:
Giving ferrous sulfate with vitamin C is beneficial because vitamin C enhances the absorption of iron. Vitamin C (ascorbic acid) helps convert iron into a form that is more easily absorbed by the body. Therefore, administering ferrous sulfate with a source of vitamin C, such as orange juice, can improve its effectiveness.
Choice C reason:
It is best to give ferrous sulfate with food to reduce gastrointestinal side effects. While iron is best absorbed on an empty stomach, it can cause stomach upset, nausea, and constipation. Taking the medication with food can help mitigate these side effects, making it more tolerable for the child.
Choice D reason:
Giving ferrous sulfate with milk is not recommended. Dairy products, including milk, can interfere with the absorption of iron. Calcium in milk binds with iron, reducing its bioavailability and effectiveness. Therefore, it is best to avoid giving ferrous sulfate with milk or other dairy products.
Correct Answer is ["B","C","D"]
Explanation
Choice A: Increase Sodium Intake
Increasing sodium intake is generally not recommended for patients with renal disorders. High sodium intake can lead to fluid retention, hypertension, and worsening of kidney function. Patients with renal disorders are often advised to follow a low-sodium diet to manage these risks.
Choice B: Monitor Intake/Output
Monitoring intake and output (I/O) is crucial for patients with renal disorders. It helps in assessing kidney function and fluid balance. Accurate measurement of fluid intake and urine output can provide valuable information about the patient’s hydration status and kidney function. This intervention is essential for preventing fluid overload and dehydration.
Choice C: Daily Weights
Daily weights are an important intervention for patients with renal disorders. Monitoring weight daily helps in detecting fluid retention early. Sudden weight gain can indicate fluid overload, which is a common issue in patients with kidney problems. By tracking daily weights, healthcare providers can make timely adjustments to the patient’s treatment plan.
Choice D: Monitor Blood Pressure
Monitoring blood pressure is a key intervention for patients with renal disorders. Hypertension is both a cause and a consequence of kidney disease. Regular monitoring of blood pressure helps in managing hypertension and preventing further damage to the kidneys. It also aids in assessing the effectiveness of antihypertensive medications.
