Correct Answer is ["2"]

Explanation

Given:

Desired dose of ibuprofen: 200 mg
Available strength of ibuprofen oral suspension: 100 mg/5 mL

First, find out the concentration of ibuprofen in mg/mL:

Concentration = 100 mg / 5 mL Concentration = 20 mg/mL

Now, calculate how many milliliters (mL) of ibuprofen oral suspension are needed to achieve the desired dose:

Volume (mL) = Desired dose / Concentration Volume (mL) = 200 mg / 20 mg/mL

Volume (mL) = 10 mL

Since 1 teaspoon (tsp) is approximately 5 milliliters (mL), the nurse should instruct the client to take:

Number of teaspoons = Volume (mL) / 5 mL per tsp Number of teaspoons = 10 mL / 5 mL per tsp Number of teaspoons = 2 tsp

So, the nurse should instruct the client to take 2 teaspoons of ibuprofen oral suspension.

Correct Answer is ["1 "]

Explanation

Given:

Desired dose of metronidazole: 7.5 mg/kg
Client's weight: 146.7 lb
Available strength of metronidazole tablets: 500 mg

First, convert the client's weight from pounds to kilograms:

146.7 lb ÷ 2.20462 = 66.57 kg (rounded to the nearest hundredth)

Now, calculate the desired dose of metronidazole:

Desired dose = Dosage per kg × Weight Desired dose = 7.5 mg/kg × 66.57 kg Desired dose ≈ 498.775 mg

Next, find out how many tablets are needed to achieve this dose: Number of tablets = Desired dose / Strength per tablet

Number of tablets = 498.775 mg / 500 mg Number of tablets ≈ 0.997

Since we cannot administer a fraction of a tablet, the nurse should administer 1 tablet of metronidazole.
