The client is to receive an oral suspension of drug H 75mg PO. The nurse has drug H available in a suspension 0.15 g/5mL. What should the nurse administer? Round of to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.

Answer and Explanation

The Correct Answer is ["2.5"]

To determine the correct volume to administer, follow these steps:
1. Convert the dose from milligrams to grams:
75 mg = 0.075 grams (since 1000 mg = 1 gram)

2. Use the concentration of the suspension to find the volume:
The concentration is 0.15 g/5 mL.
Set up a proportion: (0.15 g / 5 mL) = (0.075 g / X mL)
Solve for X: X = (0.075 g x 5 mL) / 0.15 g = 2.5 mL

3. Round to the nearest tenth:
2.5 mL is already rounded to the nearest tenth.

Correct Answer is ["11"]

Explanation

To determine the correct IV pump rate for the heparin infusion, follow these steps:

1. Calculate the concentration of heparin in units per mL:
The concentration is 25000 units in 250 mL.
Therefore, 25000 units / 250 mL = 100 units/mL.

2. Determine the infusion rate in mL per hour:
The ordered dose is 1100 units per hour.
Using the concentration, 1100 units/hr / 100 units/mL = 11 mL/hr.

Correct Answer is ["0.4"]

Explanation

To determine the correct volume to administer, follow these steps:

1. Convert the available concentration to mg/mL:
6 grams = 6000 mg (since 1 gram = 1000 mg)
Therefore, 6000 mg / 10 mL = 600 mg/mL.

2. Calculate the volume to administer:
The ordered dose is 250 mg.
Volume to administer = 250 mg / 600 mg/mL = 0.4167 mL.

3. Round to the nearest tenth:
0.4167 mL rounded to the nearest tenth is 0.4 mL.
