A critical care nurse is managing a client with severe decompensated heart failure. The client has an admission weight of $184.8 \text{ lbs}$.

The provider's prescription reads:
- Initiate dobutamine continuous IV infusion at $2.5 \text{ mcg/kg/min}$.
- Titrate upward by $2.5 \text{ mcg/kg/min}$ every $15 \text{ minutes}$ until mean arterial pressure (MAP) $> 65 \text{ mm Hg}$, up to a maximum dose of $20 \text{ mcg/kg/min}$.

The pharmacy dispenses a customized dobutamine solution containing $1,000 \text{ mg}$ of dobutamine in $250 \text{ mL}$ of $5\%$ dextrose in water (D5W). A dedicated central venous catheter port is used for the infusion, alongside a separate line of $0.9\%$ sodium chloride running at $20 \text{ mL/hr}$.

After initiating the infusion, the nurse performs exactly three upward titrations over the next $45 \text{ minutes}$ before the client's MAP stabilizes at $72 \text{ mm Hg}$.

What is the dobutamine infusion pump rate in $\text{mL/hr}$ at this effective dose? (Record your answer to the nearest tenth.)

A nurse is caring for a client who is admitted with a deep vein thrombosis (DVT). The healthcare provider prescribes a continuous intravenous (IV) infusion of heparin at a rate of $18$ units/kg/hr. The client weighs $176$ lb. The pharmacy provides an IV bag containing $25,000$ units of heparin mixed in $250$ mL of $5\%$ dextrose in water (D5W).

A critical care nurse is managing a client with severe sepsis. The client is receiving a continuous intravenous infusion of norepinephrine.

Client Data:
- Weight: $220$ lb
- Current mean arterial pressure (MAP): $54$ mm Hg
- Current infusion pump rate: $18$ mL/hr
- Medication concentration: Norepinephrine $8$ mg in $250$ mL $5\%$ Dextrose in Water (D5W)
- Provider titration protocol: "Increase norepinephrine by $0.04$ mcg/kg/min every $5$ minutes until MAP is $\geq 65$ mm Hg."

The nurse determines the need to increase the infusion rate according to the protocol. What should be the newly programmed infusion pump rate in mL/hr?
