At exactly 5 minutes after birth, a transition nurse completes a physiological assessment on a newly delivered term infant. The nurse documents an apical heart rate of 96 beats per minute. The infant is exhibiting a weak, gasping cry. When the soles of the feet are gently flicked, the infant responds with a slight grimace but no active withdrawal. The infant's muscle tone reveals flaccid extremities. The skin color is centrally pink with noticeably blue hands and feet.

What is the infant's 5-minute Apgar score?

A mechanically ventilated client in the intensive care unit requires continuous sedation. The healthcare provider's order reads: dexmedetomidine $0.8\text{ mcg/kg/hr}$ continuous IV infusion. The client weighs $154\text{ lb}$. The pharmacy dispenses a pre-mixed solution containing $200\text{ mcg}$ of dexmedetomidine in $50\text{ mL}$ of $0.9\%$ sodium chloride.

At what rate, in $\text{mL/hr}$, should the infusion pump be programmed? Record your answer using a whole number.

During a shift in the intensive care unit, the nurse assumes care for a patient in cardiogenic shock whose current weight is $80\text{ kg}$. The patient has a central venous catheter infusing dobutamine at a rate of $24\text{ mL/hr}$. The IV bag is labeled as containing $500\text{ mg}$ of dobutamine mixed in $250\text{ mL}$ of normal saline. Following a hemodynamic assessment, the critical care prescriber instructs the nurse to increase the dobutamine dosage by $2.5\text{ mcg/kg/min}$. Calculate the new rate at which the nurse should program the infusion pump. Record your answer in $\text{mL/hr}$ as a whole number.

A critical care nurse is managing a client with symptomatic bradycardia who is unresponsive to standard atropine therapy. The client weighs $187\text{ lbs}$. The healthcare provider prescribes a continuous IV infusion of dopamine at $4\text{ mcg/kg/min}$. The pharmacy supplies a premixed bag containing $250\text{ mg}$ of dopamine in $500\text{ mL}$ of $5\%$ dextrose in water (D5W). What is the correct infusion pump setting in $\text{mL/hr}$? Record your answer using one decimal place.
