Question

i dont understand the formula to calculate the answer or what theyre asking me for

500mg 2. The client weighs 136 pounds. The client is to receive 15 mg of a medication every 6 hours. The maximum recommended dose of this medication is 870 mcr/kg/day. Is this a safe dose? 61.8kg 60,000 mg daily yes-safe dose 3. The client weighs 179 pounds. The IV is running at 23 ml/hr. The medication is supplied as 800mg in 500ml. Calculate the mcg/kg/min. 7.5 013 8000D/81.3 / in X81860 1600 4. The client is receiving heparin at 1400 units/hr. PTT results are low and the infusion is to be increased by 150 units/hour. Heparin is supplied as 25,000 units in 500ml. Calculate flow rate. 5. A client is to receive dopamine at 9 mcg/kg/min. The medication is supplied in 400 mg/500ml. The client weighs 216 pounds. Calculate the flow rate. 6. The client weighs 68 kilograms. The IV is running at 27 ml/hr. The medication is supplied as 800mg in 500ml. Calculate the meg/kg/min.

Answer 1

4. Heparin 1400 units / hour + 150 units / hour = 1550 units/ hour

Required dose in volume = required dose $\times$ available drug in ml $\div$ available dose

                                         = 1550 $\times$ 500 $\div$ 25000

                                         = 31

The required flow rate is 31ml/ hour

5. Dopamine 9 mcg/kg/min

Patient weight = 216 pounds = 98 kgs

Dopamine 9 $\times$ 98 = 882 mcg/min

Medication is supplied in 400 mg/500 ml = 400000mcg/500 ml (to convert mg to mcg multiply with 1000)

Required dose in volume = required dose $\times$ available drug in ml $\div$ available dose

                                        = 882 $\times$ 500 $\div$ 400000

                                        = 1

The required flow rate is 1ml/min

6. Supplied medication is 800 mg/500ml

Dose in 1 ml = 800 $\div$500

                    = 1.6 mg/ml

The patient receiving a dose per hour = 27 $\times$ 1.6

                                                            = 43.2 mg/hr

To get dose per minute = 43.2 $\div$60

                                     = 0.72 mg/min = 720 mcg/min

To get dose per kg body weight = 720 $\div$68

                                                   = 10.6

The IV is running with 10.6 mcg/kg/min
