| What is the purpose of magnesium sulfate in labor and delivery? | Prevention of seizures related to pregnancy-induced hypertension |
| A 50 mL syringe contains ______ g of 25% magnesium sulfate. Use numbers only. | 25/100 x 50 = 12.5 g |
| The nurse needs to give a loading dose of 4 gram magnesium sulfate over 30 minutes. The pharmacy provides 500 mL of 0.9% normal saline (NS) with 20 gram magnesium sulfate. Based on this, the IV rate is ______ mL/hr. | 500 x 4 x 60 = 120,000 /20 x 30 = 600 ===120,000/600 = 200 |
| At completion of the loading dose, the nurse will start a continuous infusion of magnesium sulfate at 3g/hr. The pharmacy provides 1,000mL of 0.9% gr of magnesium sulfate. The IV rate is ______ mL/hr. | 3,000/20 =150mL/hr |
| The healthcare provider orders 1,000 mL D5W with 15 units of IV Pitocin. Begin at 2 mU/min and then increase by 1 mU/min until active labor begins. The maximum dose is 22 mU/min. Based on this, the beginning infusion rate is ____ mL/hr. | 1000 / 15,000 x 2 x 60 = 8mL/hr |
| The healthcare provider orders 1,000 mL D5W with 10 units of IV Pitocin. The healthcare provider begins at 2 mU/min and then increases by 1 mU/min until active . The maximum dose is 20 mU/min. Based on this, the maximum infusion rate is ____ mL/hr. | 1000 / 10,000 x 20 x 60 = 120 mL/hr |
| The healthcare provider orders 1,500 mL D5W with 10 units of IV Pitocin. The healthcare provider begins at 1 mU/min and then increases by 1 mU/min until active labor begins.The maximum dose is 20 Based on this, the beginning infusion rate is ____ mL/hr. | 1500 / 10,000 = 0.15 x 60 = 9mL |
| The healthcare provider orders 800 mL D5W with 12 units of IV Pitocin. The healthcare provider begins at 2 mU/min and then increases by 1 mU/min until active labor begins. The maximum dose is 20 mU/min. Based on this, the maximum infusion rate is mL/hr | 800 x 20 /12,000 = 1.3 x 60 = 78 mL/hr |
| Which term is synonymous with loading dose? | Bolus |
| The nurse has a 10 mL vial of 50% magnesium sulfate. The nurse has to prepare a loading dose of 1,000 mg. The nurse will require mL. | 50% x 10 = 5 50g /100mL = 2mL |
| The patient is to receive 1 gram per hour continuously of magnesium sulfate after an initial loading dose. The medication will be added to a 1,000 mL IV bag, running at 100 mL/hour. The amount of magnesium in the IV bag is g. | 1000/100 = 10 |
| The healthcare provider orders 500 mL D5W with 20 units of IV Pitocin. The healthcare provider begins at 2 mU/min and then increases by 1 mU/min until active labor begins. The maximum dose is 40 mU Based on this, the beginning infusion rate is mL/hr. | 500 / 20,000 x 2 x 60 = 3 mL/hr |
| The healthcare provider orders 1,200 mL D5W with 10 units of IV Pitocin. The healthcare provider begins at 2 mU/min and then increases by 1 mU/min until active labor begins. The maximum dose is 25 mU/min. Based on this, the maximum infusion rate is mL/ | 1200 / 10,000 x 25 x 60 = 180 |
| The healthcare provider orders 750 mL D5W with 25 units of IV Pitocin. The healthcare provider begins at 3 mU/min and then increases by 2 mU/min until active labor begins. The maximum dose is 30 mU/min. Based on this, the beginning infusion rate is __ mL/ | 750/25,000 x 3 x 60 = 5.4 |
| A healthcare provider orders 2 L D5W with 15 units of IV Pitocin. The healthcare provider begins at 1 mU/min and then increases by 1 mU/min until active labor begins. The maximum dose is 35 mU/min. Based on this, the maximum infusion rate is __ mL/hr. | 2000 /15,000 x 35 x 60 =280 |
