Order: cephalexin (Keflex) 0.5 gp.o. qid. Available: cephalexin (Keflex) 250 mg capsules. How many capsules will the nurse administer?
The Correct Answer is ["2"]
To determine the number of capsules the nurse will administer, we need to consider the dosage prescribed and the available strength of the capsules.
The prescription states: cephalexin (Keflex) 0.5 g p.o. qid (four times a day).
Given that the available strength of cephalexin capsules is 250 mg, we need to convert the prescribed dosage from grams (g) to milligrams (mg) to match the capsule strength.
1 g = 1000 mg
0.5 g = 0.5 * 1000 mg = 500 mg
Now we know that the prescribed dosage is 500 mg, and each capsule contains 250 mg.
To calculate the number of capsules needed, we divide the prescribed dosage by the strength of each capsule:
Number of capsules = Prescribed dosage / Capsule strength
Number of capsules = 500 mg / 250 mg
Number of capsules = 2
Therefore, the nurse will administer 2 capsules of cephalexin (Keflex) for each dose.

Correct Answer is ["30"]
Explanation
1 fluid ounce (fl oz) is equal to approximately 29.57 milliliters (ml). The conversion factor between fluid ounces and milliliters is not an exact value due to the difference between the U.S. fluid ounce and the metric milliliter. However, for most practical purposes, 1 fluid ounce is commonly rounded to 30 milliliters (ml) for simplicity.
Correct Answer is ["4.54"]
Explanation
To convert pounds (lbs) to kilograms (kg), we need to use the conversion factor: 1 pound = 0.45359237 kilograms
Now, let's calculate the weight of the baby in kilograms:
Weight in kilograms = Weight in pounds * Conversion factor
Weight in kilograms = 10 lbs * 0.45359237 kg/lb
Weight in kilograms ≈ 4.5359237 kg
Therefore, the baby weighs approximately 4.54 kilograms.
