A nurse is preparing to administer lactated Ringer's 75 mL/hr by continuous IV infusion. The drop factor on the manual IV tubing is 20 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min? (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 ["25"]

To calculate the IV flow rate in gtt/min, you need to multiply the infusion rate in mL/hr by the drop factor in gtt/mL and divide by 60 min/hr. In this case, the formula is (75 mL/hr x 20 gtt/mL) / 60 min/hr = 25 gtt/min. Therefore, the nurse should set the IV flow rate to deliver 25 gtt/min.

Correct Answer is ["4"]

Explanation

To administer verapamil 10 mg IV bolus, the nurse should use the following formula: mL = (mg / mg/mL) x mL. Plugging in the values from the question, we get: mL = (10 / 5) x 2. Simplifying, we get: mL = 4. Therefore, the nurse should administer 4 mL of verapamil injection.

Correct Answer is ["20.1"]

Explanation

To calculate the dosage of methylprednisolone, first convert the client's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds.

The client weighs 184 pounds, which is approximately 83.64 kilograms (184 lb / 2.2).

Next, multiply the client's weight in kilograms by the dosage prescribed, which is 30 mg/kg.

This results in a total dosage of 2509.2 mg (83.64 kg * 30 mg/kg).

Finally, divide the total dosage by the concentration of the available medication to find out how many milliliters to administer.

The available medication is 125 mg/mL,

so you would administer 20.07 mL (2509.2 mg / 125 mg/mL).

Rounded to the nearest tenth, the nurse should administer 20.1 mL.
