A nurse is preparing to administer phenytoin 15 mg/kg PO as a loading dose to a client who weighs 264 lb. How many mg should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1800"]

Convert weight from pounds (lb) to kilograms (kg):

We know 1 kg is equal to 2.2 lb.

Client's weight (kg) = 264 lb / 2.2 lb/kg = 120 kg (rounded to nearest whole number)

Calculate total phenytoin dosage:

Dosage (mg) = Client's weight (kg) × Dosage per kg (mg/kg)

Dosage (mg) = 120 kg × 15 mg/kg

Dosage (mg) = 1800 mg

Round the answer to the nearest whole number:

Rounded dosage = 1800 mg

Therefore, the nurse should administer 1800 mg of phenytoin.

Correct Answer is ["0.5"]

Explanation

Desired dose: 100 mg

Concentration of available amoxicillin suspension: 200 mg/5 mL

Steps to find the volume to administer (in teaspoons):

Calculate the volume in milliliters (mL):

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

Volume (mL) = 100 mg / 200 mg/5 mL

Convert milliliters (mL) to teaspoons (tsp) considering rounding:

Since 1 teaspoon (tsp) is approximately equal to 5 mL, we can directly convert while considering rounding to avoid unnecessary precision loss.

Since 5 mL is divisible by 200 mg (desired dose), rounding won't affect the final answer significantly.

Therefore,

Volume (tsp) = Volume (mL) / Conversion factor (mL/tsp) (rounded to nearest tenth)

Volume (tsp) = 100 mg / (200 mg/5 mL) ≈ 0.5 tsp (rounded to nearest tenth)

Correct Answer is ["1.8"]

Explanation

Here's the breakdown:

Convert client weight to kilograms (kg):

Client weight (kg) = Client weight (lb) / 2.2 lb/kg

Client weight (kg) = 154 lb / 2.2 lb/kg

Client weight (kg) ≈ 70 kg (rounded to nearest whole number)

Calculate desired gentamicin dose in milligrams (mg):

Desired dose (mg) = Client weight (kg) x Dose per kg

Desired dose (mg) = 70 kg x 1 mg/kg

Desired dose (mg) = 70 mg

Determine the volume of gentamicin solution to administer:

Concentration of available solution: 40 mg/mL

Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)

Volume to administer (mL) = 70 mg / (40 mg/mL)

Volume to administer (mL) = 1.75 mL (round to nearest tenth)

Therefore, the nurse should administer 1.8 mL of the gentamicin solution.
