Showing 10 questions, Sign in for moreA nurse is preparing to administer 0.9% sodium chloride IV infusion 1-L bag at a rate of 200 mL/hr for a client who has rhabdomyolysis. The nurse should expect the IV pump to infuse over how many hours? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Total volume to be infused = 1000 mL
Desired infusion rate = 200 mL/hr
To determine the infusion time, we can use the formula:
Infusion time (hours) = Total volume (mL) / Infusion rate (mL/hr)
Substituting the values:
Infusion time = 1000 mL / 200 mL/hr = 5 hours
Therefore, the IV pump will infuse for 5 hours.
A nurse is preparing to administer 000 mL of lactated Ringer's IV over 6 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Calculate the total infusion time in minutes:
6 hours X 60 minutes/hour = 360 minutes
Calculate the total number of drops:
1000 mL X 10 gtt/mL = 10,000 gtt
Calculate the drip rate:
Drip rate (gtt/min) = Total drops / Total infusion time (minutes)
Drip rate = 10,000 gtt / 360 minutes = 27.78 gtt/min
Rounded to the nearest whole number, the drip rate is 28 gtt/min.
A client is to receive enoxaparin 30 mg subcutaneously. Available is enoxaparin 40 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Desired dose = 30 mg
Available concentration = 40 mg/mL
To calculate the volume to administer, use the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL)
Volume = 30 mg / 40 mg/mL = 0.75 mL
Rounded to the nearest tenth, the nurse should administer 0.8 mL of enoxaparin.
A nurse is completing an 8-hr 1&O record for a client who consumed 4 oz juice. 6 oz tea, a 100 mL cup full of ice chips. an IV bolus of 150 mL, and 8 oz broth. The nurse should record how many mL of intake on the client's record?
Explanation
Here's the breakdown of the calculations:
1 ounce = 30 mL
4 oz juice = 4 X 30 mL = 120 mL
6 oz tea = 6 X 30 mL = 180 mL
8 oz broth = 8 X 30 mL = 240 mL
Total intake = 120 mL + 180 mL + 100 mL + 150 mL + 240 mL = 790 mL
Since ice chips are mostly water, they are counted as intake.
Therefore, the nurse should record 790 mL of intake on the client's record.
A nurse is caring for a client who has a pulmonary embolism and has a new prescription for enoxaparin 5mg/kg/dose subcutaneous every 12 hr. The client weighs 245 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Convert pounds to kilograms: 245 lbs / 2.2 lbs/kg = 111.36 kg
Calculate the enoxaparin dose: 1.5 mg/kg X 111.36 kg = 167.04 mg
Round to the nearest whole number: 167 mg
Therefore, the nurse should administer 167 mg of enoxaparin per dose.
A nurse is preparing to administer dextrose 5% in water (DSW) 150 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Convert hours to minutes: 3 hours X 60 minutes/hour = 180 minutes
Calculate the total number of drops: 150 mL X 10 gtt/mL = 1500 gtt
Calculate the drip rate: 1500 gtt / 180 minutes = 8.33 gtt/min
Round to the nearest whole number: 8 gtt/min
A nurse is preparing to administer digoxin 8 mcg/kg/day PO to divide equally every 12 hr for a preschooler who weighs 33 lb. Available is digoxin elixir 0.05 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Explanation
Convert weight to kg: 33 lb ÷ 2.2 lb/kg = 15 kg
Calculate total daily dose: 8 mcg/kg/day X 15 kg = 120 mcg/day
Calculate single dose: 120 mcg/day ÷ 2 doses = 60 mcg/dose
Convert mcg to mg: 60 mcg = 0.06 mg
Calculate volume to administer: 0.06 mg ÷ 0.05 mg/mL = 1.2 mL
Round to the nearest tenth: 0.6 mL
A nurse is preparing to administer clindamycin 300 mg by intermittent IV bolus over 30 min to a client who has a staphylococci infection. Available is clindamycin premixed in 50 mL 0.90% sodium chloride (NaCl). The nurse should set the IV 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.)
Explanation
Convert minutes to hours: 30 minutes = 0.5 hours
Calculate the infusion rate: 50 mL / 0.5 hours = 100 mL/hr
A nurse is preparing to administer ticarcillin/clavulanate 3.1 g by intermittent IV bolus over 30 min. Available is ticarcillin/clavulanate 3.1 g in 50 mL 0.9% sodium chloride (NSS). The nurse should set the IV 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.)
Explanation
To calculate the IV pump rate in mL/hr, follow these steps:
Total volume to be infused: 50 mL
Infusion time: 30 minutes
Convert the infusion time to hours:
30 minutes ÷ 60 minutes/hour = 0.5 hours
Calculate the IV pump rate:
Rate (mL/hr) = Total volume (mL) ÷ Infusion time (hours)
Rate = 50 mL ÷ 0.5 hours = 100 mL/hr
The nurse should set the IV pump to deliver 100 mL/hr.
A nurse is reviewing a client's prescription for 1.000 mL of 5% dextrose in water IV to infuse over 8 hr. At 1400, the nurse observes that there is 500 mL of solution remaining in the client's current IV bag. At what time should the nurse administer the next bag of IV solution?
