When adding the prescribed dose to the volume control device, how many ml of IV solution should the nurse add to dilute? (Enter numeric value only. If rounding is required, round to the nearest tenth.)
16.8 First, calculate the amount of milliliters of medication needed to provide 800 mg of nafcillin. Prescribed dose (800 mg) divided by dose on hand (250 mg/ml) equals 3.2 mlNext, determine the recommended concentration using equivalent fractions. 800 mg/X = 40 mg/1 ml40X = 800 = 20 ml (the total volume at the recommended concentration)20 ml (total volume) minus the 3.2 ml (800 mg dose) equals an additional 16.8 ml of fluid to be added to the volume control device to obtain the recommended concentration.
A client with a gastrostomy tube (GT) receives a prescription for Osmolite 1/2 strength enteral formula at 80 ml/hour. To prepare a 4 hour solution, the nurse should dilute the full-strength formula with how many ml of water? (Enter numeric value only.)
160 Determine the total volume needed at 80 ml/hour x 4 hours = 320 ml. Use the formula, Desired strength/strength on Hand x Volume = 50/100 x 320 = 160 ml of Osmolite enteral formula, which must be diluted to half strength. Or use ratio and proportion, Desired strength (1/2 = 1 part : 2 parts) :: Volume of full strength : Total Desire volume = 1 : 2 :: X : 320 ml 2X = 320, and X = 160 ml of Osmolite enteral formula, full strength 320 ml total volume - 160 ml of full-strength formula = 160 ml of water to create 1/2 strength or 50% concentration
The healthcare provider prescribes the adjustment of the IV hourly rate based on the nasogastric tube (NGT) output every 4 hour for a client who had abdominal surgery yesterday. From 1200 to 1600, the NGT output was 240 ml, and the IV ofDextrose 5% in 0.45% Sodium chloride (D51/2 NS) was infused at a rate of 100 ml/hour. At 1600 the nurse should regulate the IV to deliver how many ml/hour to replace this fluid loss? (Enter numeric value only, using a whole number.)
160 To calculate the hourly rate of IV fluid replacement based on the last 4 hours of NGT output, the nurse should calculate an average hourly output by dividing 240 ml by 4 hours = 60 ml NGT output every 1 hour.The nurse should then add the 60 ml loss per hour to the present infusion rate of 100 ml/hr, totaling an infusion rate of 160 ml/hour for the next 4 hours.

A client who has been NPO for 3 days is receiving an infusion of Dextrose 5% in 0.45% Sodium chloride (D51/2 NS) with potassium chloride (KCl) 20 mEq at 83 ml/hour. The client's 8-hour urine output is 400 ml, blood urea nitrogen (BUN) is 15 mg/dl (5.355 mmol/L), lungs are clear bilaterally, serum glucose is 110 mg/dl ( 6.1 mmol/L), and serum potassium is 3.7 mEq/L (3.7 mmol/L). Which action should the nurse implement? Notify healthcare provider and request to change the IV infusion to hypertonic D10W. Decrease in the infusion rate of the current IV and report to the healthcare provider. Document in the medical record that these normal findings are expected outcomes. Obtain potassium chloride 20 mEq in anticipation of a prescription to add to present IV.
Document in the medical record that these normal findings are expected outcomes. Rationale The results are all within normal range (BUN 10 to 20 mg/dl or 3.6-7.1 mmol/L (SI units), serum glucose 70 to 110 mg/dl or less than 6.1 mmol/L (SI), and serum potassium 3.5 to 5.0 mEq/L or 3.5-5.0 mmol/L (SI units). The other actions are not indicated.
The nurse is caring for a client who is receiving 24-hour total parenteral nutrition (TPN) via a central line at 54 ml/hr. When initially assessing the client, the nurse notes that the TPN solution has run out and the next TPN solution is not available. What immediate action should the nurse take? Infuse normal saline at a keep vein open rate. Discontinue the IV and flush the port with heparin. Infuse 10% dextrose and water at 54 ml/hour. Obtain a stat blood glucose level and notify the healthcare provider.
Infuse 10% dextrose and water at 54 ml/hour. Rationale TPN should be discontinued gradually to allow the client to adjust to decreased levels of glucose. Administering 10% dextrose in water at the prescribed rate should reduce the client's risk of hypoglycemia until the next TPN solution is available. The other actions are not indicated.
A client is receiving a cephalosporin antibiotic IV and complains of pain and irritation at the infusion site. The nurse observes erythema, swelling, and a red streak along the vessel above the IV access site. Which action should the nurse take? Administer the medication more rapidly using the same IV site. Initiate an alternate site for the IV infusion of the medication. Notify the healthcare provider before administering the next dose. Give the client a PRN dose of aspirin while the medication infuses.
Initiate an alternate site for the IV infusion of the medication. Rationale A cephalosporin antibiotic that is administered IV may cause vessel irritation. Rotating the infusion site minimizes the risk of thrombophlebitis, so an alternate infusion site should be initiated before administering the next dose. The other actions are not indicated.
What action should the nurse implement when accessing an implanted infusion port for a client who receives long term IV medications? Cleanse the site with iodine solution. Insert a Huber-point needle into the port. Flush tubing with 5 ml of normal saline. Place a sterile dressing over the port.
Insert a Huber-point needle into the port. Rationale An implanted infusion port needs to be accessed using a Huber-point needle (non-coring) to be prevent damage to the self-sealing septum of the port. The other actions are not necessary when accessing an implanted infusion port.
A client's IV infusion of 0.9% Sodium Chloride (normal saline) infiltrated earlier today, and approximately 500 ml of normal saline infused into the subcutaneous tissue. The client is now complaining of excruciating arm pain and demanding "stronger pain medications." What action is most important for the nurse to take? Ask about any past history of drug abuse or addiction. Measure the pulse volume and capillary refill distal to the infiltration. Compress the infiltrated tissue to measure the degree of edema. Evaluate the extent of ecchymosis over the forearm area.
Measure the pulse volume and capillary refill distal to the infiltration. Rationale Compartment syndrome occurs when external pressure (usually from a cast), or internal pressure (usually from subcutaneous infused fluid), exceeds capillary perfusion pressure resulting in decreased blood flow to the extremity. The most important action is to assess pulse volume and capillary refill distal to the infiltration site toetermin d loss of the peripheral pulse in the extremity, which is evidence of compartment syndrome. The other actions are of less priority than determining the effects of the infiltrate fluids on circulation and nerve function.
A client is receiving Dextrose 5% in Water (D5W) 1,000 ml at 75 ml/hour. The nurse hangs the bag of IV fluids at 0300. At what time, based on the 24-hour clock, should the infusion be completed? a) 1620. b) 1630. c) 0420. d) 0430.
a) 1620 Calculate the number of hours an IV bag of 1,000 ml should infuse, 1,000 ml / 75 ml/hour = 13.3 hr = 13 hours 20 minutes.Calculate the time, 0300 AM + 1320 = 1620 by the 24-hour clock (or 4:20 PM).
Amoxicillin 500 mg PO every 8 hours is prescribed for a client with an infection. The drug is available in a suspension of 125 mg/5ml. How many ml should the nurse administer with each dose? a) 20 ml. b) 4 ml. c) 100 ml. d) 10 ml.
a) 20 mL 500 : X :: 125 : 5 125X = 2,500 X = 20 ml
The healthcare provider prescribes diltiazem (Cardizem) 0.87 mg PO four times daily for an infant who weighs 22 pounds. The recommended maximum dose is 3.5 mg/kg/day. What action should the nurse take? a) Give the prescribed dosages. b) Notify the healthcare provider. c) Ask the pharmacist to clarify the calculations. d) Assess the child's heart rate before administration.
b) Notify the healthcare provider. Calculate the recommended maximum dose, 22 pounds = 10 kg, so 3.5 mg x 10 kg = 35 mg.Calculate the prescribed daily dose. 0.87 mg x 4 doses = 3.48 = 3.5 mg/day.The prescribed daily dose 3.5 mg/day is below the recommended dose of 35 mg, which may be a misplaced decimal in the prescription.The healthcare provider should be notified for clarification of the dosage.
