A nurse is preparing to administer enoxaparin 1 mg/kg subcutaneously to a client who weighs 220 lb. Available is enoxaparin 30 mg/0.3 mL. How many mL 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 ["1"]

To calculate the correct dose of enoxaparin, we need to follow these steps:

Convert pounds to kilograms:
- 220 lb * 0.4536 kg/lb = 99.8 kg
Calculate the daily dose in micrograms:
- 1 mg/kg * 99.8 kg = 99.8 mg
Determine the volume needed from the available concentration:
- 99.8 mg * (0.3 mL / 30 mg) = 0.998 mL

Therefore, the nurse should administer 1 mL of enoxaparin.

Answer: 1 mL

Correct Answer is ["2"]

Explanation

The nurse should administer 2 capsules of nifedipine per dose

Here's the breakdown:

Desired dose per administration: 20 mg

Strength of available capsules: 10 mg per capsule

To find the number of capsules needed, we can divide the desired dose by the amount of medication in each capsule and round to the nearest whole number:

Number of capsules (rounded) = Desired dose / Medication per capsule

= 20 mg / 10 mg/capsule

= 2 capsules (rounded to nearest whole number)

Therefore, the nurse should administer 2 capsules of nifedipine per dose.

Correct Answer is ["3.00"]

Explanation

The nurse should administer 3 tablets of calcium carbonate per dose.

Here's the breakdown:

Daily dose: 3.9 g

Dose frequency: Every 12 hours (meaning two doses per day)

Tablet strength: 650 mg per tablet

Step 1: Convert daily dose to milligrams

Since tablets are typically measured in milligrams (mg), we need to convert the daily dose from grams (g) to milligrams (mg). There are 1000 milligrams in one gram:

Daily dose (mg) = 3.9 g x 1000 mg/g

= 3900 mg

Step 2: Calculate the dose per administration

Since the total daily dose is given to be administered in equally divided doses every 12 hours, we need to find the amount to be administered per dose

Dose per administration = Daily dose / Number of doses per day

= 3900 mg / 2 doses/day

= 1950 mg

Step 3: Find the number of tablets per dose

Now, we can determine how many tablets are needed to deliver the calculated dose per administration.

We can divide the dose per administration by the strength of each tablet (rounding to the nearest whole number):

Number of tablets (rounded) = Dose per administration / Tablet strength

= 1950 mg / 650 mg/tablet

= 3.00 tablets (round to 3)
