A nurse is preparing to instill 840 mL of enteral nutrition via a client's gastrostomy tube over 24 hr using an infusion pump. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)_mL/hr
Answer and Explanation

The Correct Answer is ["35"]

Here's the calculation:

 

Total volume of enteral nutrition (mL): 840 mL

Infusion time (hours): 24 hours

Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours)

 

Flow rate (mL/hr) = 840 mL / 24 hours = 35 mL/hr (round to nearest whole number as requested)

 

Therefore, the nurse should program the pump to deliver 35 mL/hr.

Correct Answer is ["32"]

Explanation

Find the concentration of heparin in the solution:

Total heparin (units): 25,000 units

Volume of solution (mL): 500 mL

Heparin concentration (units/mL) = Total heparin (units) / Volume of solution (mL)

Heparin concentration (units/mL) = 25,000 units / 500 mL = 50 units/mL

Set up the flow rate equation:

Desired heparin infusion rate (units/hr): 1600 units/hr

Heparin concentration in solution (units/mL): 50 units/mL

Flow rate (mL/hr): We need to solve for this

Flow rate (mL/hr) = Desired heparin infusion rate (units/hr) / Heparin concentration (units/mL)

Calculate the flow rate (mL/hr):

Flow rate (mL/hr) = 1600 units/hr / 50 units/mL = 32 mL/hr (round to nearest whole number as requested)

Therefore, the nurse should set the IV pump to deliver approximately 32 mL/hr.

Correct Answer is ["2"]

Explanation

Here's how to find the volume the nurse should administer:

Medication dose to be administered: 250 mg

Available medication concentration: 1000 mg/8 mL

We need to find the volume (in mL) that contains the desired dose (250 mg) of hydrocortisone sodium succinate.

Set up a proportion:

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

In this case:

Desired dose (mg) = 250 mg

Concentration (mg/mL) = 1000 mg/8 mL (available concentration)

Volume to administer (mL) = Unknown (what we need to find)

Available volume (mL) = 8 mL (volume of solution containing the concentrated medication)

Solve for the volume to administer (mL):

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

Volume to administer (mL) = (250 mg x 8 mL) / 1000 mg/mL

Calculate the volume:

Volume to administer (mL) = 2000 mg / 1000 mg/mL

Volume to administer (mL) = 2 mL (round to nearest whole number as requested)

Therefore, the nurse should administer approximately 2 mL of the hydrocortisone sodium succinate solution.
