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 ["1"]

Explanation

First, let's convert the client's weight from pounds (lb) to kilograms (kg) since the dosage is prescribed in mg/kg. We know that 1 kg is equal to 2.2 lb. Therefore:

Client's weight in kg = 146.7 lb / 2.2 lb/kg = 66.6 kg (rounded to two decimal places)

Now, we can calculate the total metronidazole dosage for the client using the prescribed dosage of 7.5 mg/kg:

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

= 66.6 kg × 7.5 mg/kg

= 500.25 mg (rounded to two decimal places)

Since the medication is available in 500 mg tablets, we can find the number of tablets needed by dividing the total dosage by the tablet strength:

Number of tablets = Total dosage (mg) / Tablet strength (mg/tablet)

= 500.25 mg / 500 mg/tablet

= 1.0005 (rounded to five decimal places)

Since we need to round the answer to the nearest whole number, and 1.0005 is closer to 1 than 2, the nurse should administer:

1 tablet of metronidazole.

Correct Answer is ["400"]

Explanation

Based on the image,

the medication label for amoxicillin for oral suspension states:

"Each 5 ml (1 teaspoonful) will contain amoxicillin trihydrate equivalent to 400 mg amoxicillin."

Therefore, following reconstitution,

5 mL of the amoxicillin suspension will contain 400 mg of amoxicillin.
