A child who weighs 55 lb receives a prescription for cefotaxime 150 mg/kg/day IV in divided doses every 6 hours. How many mg should the nurse administer each day?

(Enter numerical value only.)

Answer and Explanation

The Correct Answer is ["3750"]

Convert the weight to kilograms, knowing that 1 kilogram equals 2.2 pounds. The child weighs approximately 25 kilograms (55 ÷ 2.2). Then, multiply the weight in kilograms by the prescribed amount of medication, which is 150 mg/kg/day.

So, 25 kg × 150 mg/kg/day equals 3750 mg/day.

Correct Answer is ["1.3"]

Explanation

Convert pounds to kilograms.

1 pound = 0.453592 kilograms
132 pounds * 0.453592 kg/pound = 59.87 kilograms

Step 2: Calculate the total dose in micrograms.

44 micrograms/kilogram * 59.87 kilograms = 2635.08 micrograms

Step 3: Convert micrograms to milligrams.

1 milligram = 1000 micrograms
2635.08 micrograms / 1000 micrograms/milligram = 2.63508 milligrams

Step 4: Calculate the volume to be administered.

Concentration of lorazepam = 2 milligrams/milliliter
Volume = Dose / Concentration
Volume = 2.63508 milligrams / 2 milligrams/milliliter = 1.31754 milliliters

Therefore, the nurse should administer approximately 1.3milliliters of the lorazepam solution.

A. Granola, strawberries, and tea. B. Buttered whole wheat toast and coffee. C. Oatmeal, banana, and herbal tea. D. Sausage, poached eggs, and milk.

Correct Answer is C

Explanation

Rationale

A. Granola and strawberries may be high in fiber, which could potentially worsen diarrhea in some individuals. Tea is generally fine, but it should be non-caffeinated to avoid further irritation to the digestive system.

B. Whole wheat toast can be a good option as it provides carbohydrates for energy without being too heavy. However, coffee is caffeinated and can stimulate bowel movements and increase gastric acid secretion, potentially aggravating diarrhea.

C. Oatmeal is gentle on the stomach and provides soluble fiber, which can help absorb water and bulk up stools. Banana is a good source of potassium, which may be lost during episodes of diarrhea. Herbal tea is non-caffeinated and can help hydrate.

D. Sausage and milk can be high in fat and lactose, which may be difficult to digest, especially during diarrhea. Poached eggs are generally well tolerated, but the overall combination may not be ideal for someone with diarrhea.
