A nurse is preparing to administer vancomycin to a child. The order is for 50 mg/kg/day in three divided doses. The client weighs 13 kg (28.6 lbs). The medication label indicates vancomycin 500 mg in 100 mL of 0.9% saline. How many mL will the nurse administer per dose? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
43 mL
To determine the dosage per dose, first calculate the total daily dose: 50 mg/kg/day × 13 kg = 650 mg. Dividing this by three gives approximately 217 mg per dose. Since vancomycin comes as 500 mg in 100 mL, the proportionate volume for 217 mg is about 43 mL, confirming the calculation.
A: 10 mL The amount calculated does not reflect the necessary dosage based on the child's weight and the prescribed daily total.
B: 20 mL This volume significantly underestimates the required medication based on the weight-adjusted calculation and fails to provide the effective therapeutic dose.
C: 30 mL This choice also miscalculates the required dose, not aligning with the calculated needs for the child's weight and the divided administration schedule.
The primary healthcare provider (PHCP) prescribes 2350 mL of 0.9% saline to be administered over five hours to a client with severe hypovolemia. How many mL/hr will the nurse administer? Fill in the blank.
Rationale:
470 mL/hr
To calculate the hourly rate, divide the total volume of saline (2350 mL) by the total time in hours (5). This results in 470 mL/hr, which accurately addresses the required administration rate for the client experiencing severe hypovolemia.
A: 470 mL/hr This choice correctly reflects the calculated rate based on the prescribed volume and time.
B: 500 mL/hr This figure indicates an excessive rate, which would lead to an unsafe administration speed contrary to the prescribed guidelines.
C: 400 mL/hr This option underestimates the rate needed, failing to meet the necessary volume required for the client's severe hypovolemia.
D: 350 mL/hr This amount significantly underdelivers the necessary saline volume, compromising the treatment effectiveness for the hypovolemic client.
The primary healthcare provider (PHCP) prescribes cefdinir 25 mg/kg/day in divided doses every six hours. The infant weighs 8 kg (17.6 lbs). How many milligrams should the nurse administer per dose? Fill in the blank. Round your answer to a whole number.
Rationale:
50 mg
To calculate the dose per administration, the total daily dose of cefdinir is determined by multiplying the infant's weight (8 kg) by the prescribed dosage (25 mg/kg). This results in 200 mg daily, which is then divided into four doses of 50 mg each, aligning with the prescribed intervals of every six hours.
A: 25 mg
Dividing the total daily dosage by four yields a dose of 50 mg. Therefore, administering 25 mg would be insufficient for effective treatment.
B: 75 mg
Administering 75 mg exceeds the calculated dose per administration, leading to a higher total daily dosage than prescribed, which could pose risks to the infant.
C: 100 mg
A dose of 100 mg would quadruple the necessary amount per administration, thus significantly surpassing the recommended total daily dosage for the infant's weight.
A client with a stroke is prescribed alteplase. The prescription is for 0.9 mg/kg. The client weighs 116.82 kg (257 lbs). How many milligrams will the nurse administer? Fill in the blank. Record your answer to the nearest whole number.
Rationale:
105 mg
To calculate the dosage of alteplase, multiply the client's weight of 116.82 kg by the prescribed rate of 0.9 mg/kg, resulting in approximately 105 mg when rounded to the nearest whole number.
A: 94 mg. This dosage results from an incorrect calculation, as it does not accurately reflect the total weight-based prescription required for the client.
B: 100 mg. This figure represents an imprecise rounding down of the calculated dosage, failing to account for the client's full weight in the calculation needed.
C: 110 mg. This amount exceeds the calculated dosage, indicating a miscalculation of the weight-based prescription that should align with the client's actual weight.
The nurse is caring for a client who has a prescription for heparin via continuous intravenous (IV) infusion at 60 units/kg/hr. The client weighs 85 kg (187 lb). The nurse has 25,000 units/250 mL on hand. How many mL/hr should the client receive? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
51 mL/hr
To calculate the required mL/hr for the heparin infusion, first determine the total units needed: 60 units/kg/hr × 85 kg = 5100 units/hr. Then, using the concentration of 25,000 units/250 mL, the calculation 5100 units/hr ÷ (25,000 units/250 mL) gives 51 mL/hr as the correct dosage.
A: 25 mL/hr This volume would not deliver the necessary dose of heparin, significantly underdosing the client based on their weight and prescription.
B: 75 mL/hr This amount exceeds the required dosage, risking potential complications from heparin over-administration, which can lead to serious health issues such as bleeding.
C: 100 mL/hr This volume far surpasses the prescribed heparin rate, potentially causing adverse effects and contradicting the safe administration guidelines for this anticoagulant therapy.
The primary healthcare provider (PHCP) prescribes a regular insulin infusion for a client with diabetic ketoacidosis (DKA). The prescription is for 2 units/hr. The label on the medication reads 250 mL of 0.9% saline containing 100 units of regular insulin. How many mL/hr should the client receive? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
5 mL/hr
To determine the infusion rate, divide the desired insulin rate (2 units/hr) by the concentration of insulin in the solution (0.4 units/mL). This calculation yields 5 mL/hr, ensuring the client receives the appropriate dosage.
A: 2 mL/hr The calculation does not provide sufficient insulin delivery; 2 mL/hr would only yield 0.8 units of insulin, which is inadequate for treating DKA.
B: 10 mL/hr This exceeds the necessary dosage, delivering 4 units of insulin, which could potentially lead to hypoglycemia in the client.
C: 15 mL/hr This rate delivers 6 units of insulin, significantly surpassing the required dosage and posing a risk of adverse effects and complications in management.
The primary healthcare provider (PHCP) prescribes three liters of 0.9% saline to infuse over 24-hours. How many mL per hour will be administered to the client? Fill in the blank.
Rationale:
125 mL/hour
To find the infusion rate in mL per hour, divide the total volume (3,000 mL) by the total time (24 hours). This calculation results in an infusion rate of 125 mL/hour, ensuring the patient receives the prescribed saline amount safely over the specified duration.
A: 100 mL/hour This rate would result in a total volume of only 2,400 mL over 24 hours, which is insufficient compared to the prescribed three liters.
B: 150 mL/hour Administering 150 mL/hour would lead to a total of 3,600 mL over 24 hours, exceeding the intended volume and could cause fluid overload.
C: 75 mL/hour This rate corresponds to only 1,800 mL over 24 hours, significantly less than the required three liters, failing to meet the prescribed treatment.
The primary healthcare provider (PHCP) prescribes dopamine at 2.5 mcg/kg/minute. The client weighs 90 kg (198 lbs). The medication label reads dopamine 800 mg in 500 mL of dextrose 5% water (D5W). How many mL per hour will be administered to the client? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
8 mL/hr
To calculate the dosage, first determine the total required dosage for the client: 2.5 mcg/kg/min × 90 kg = 225 mcg/min. Then convert mcg to mg, resulting in 0.225 mg/min. With 800 mg in 500 mL, the infusion rate translates to 8 mL/hr, aligning with the required dosage for effective treatment.
A: 4 mL/hr The calculation of 4 mL/hr does not meet the necessary infusion rate based on the client's weight and prescribed dosage, leading to insufficient medication delivery.
B: 12 mL/hr An infusion rate of 12 mL/hr exceeds the required dosage, which could potentially lead to overdose and adverse effects due to the higher-than-necessary medication concentration.
C: 6 mL/hr Administering 6 mL/hr is inadequate, as it fails to provide the correct therapeutic dosage needed for the client based on their weight and the prescribed rate.
The corrected version of your question without the encoding error reads: The nurse is calculating intake for a client. The client received:0.9% saline at 70 mL/hr for four hours. Two eight-ounce cups of ice chips. One eight-ounce cup of coffee. Three eight-ounce cups of water. The nurse should calculate the client's total intake as how many mL? Fill in the blank.
Rationale:
1240 mL
To calculate the total intake, the nurse adds the saline (280 mL), ice chips (480 mL), coffee (240 mL), and water (720 mL). This totals 1240 mL, ensuring accurate monitoring of the client's fluid status.
A: 800 mL Saline and other fluids add up to more than this amount; therefore, this total fails to account for all sources of intake.
B: 960 mL Fails to include the total volume of ice chips, which significantly contributes to the overall fluid intake calculation.
C: 1100 mL This total does not incorporate the correct volume of saline and other beverages, resulting in an underestimation of the client’s actual intake.
A client with a stroke is prescribed alteplase. The prescription is for 0.9 mg/kg. The client weighs 61.81 kg (135.98 lbs). What is the total dose in milligrams (mg) that the client will receive? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
56 mg. The total dose of alteplase is calculated by multiplying the client's weight (61.81 kg) by the prescribed dosage (0.9 mg/kg), resulting in approximately 55.629 mg, which rounds to 56 mg.
A: 54 mg. This dose is derived from an incorrect calculation of the client’s weight, failing to utilize the full 0.9 mg/kg dosage accurately.
B: 58 mg. This figure represents a miscalculation, potentially rounding incorrectly or using an inaccurate weight, leading to an erroneous total dose.
C: 60 mg. This amount overestimates the required dosage, likely resulting from rounding up too soon or misunderstanding the weight-to-dose conversion ratio.
The primary healthcare provider (PHCP) prescribes amoxicillin 80 mg/kg/day to be given in two divided doses. The infant weighs 8.72 kg (19.18 Ibs). The label of the medication reads 250 mg/mL of amoxicillin. How many mL of amoxicillin should the nurse administer for one dose? Fill in the blank. Record your answer using 1 decimal place.
Rationale:
1.4 mL
To determine the dosage in mL, the total daily dose of amoxicillin for the infant is calculated as 80 mg/kg/day multiplied by 8.72 kg, resulting in 697.6 mg per day. Divided into two doses, each dose is 348.8 mg. Since the medication concentration is 250 mg/mL, 348.8 mg equates to 1.4 mL.
A: 0.8 mL The calculation of 0.8 mL does not account for the total required dosage based on the infant's weight and prescribed daily amount.
B: 1.0 mL This option undervalues the required dose, failing to reflect the correct total dosage needed for the infant’s weight and the prescribed amount.
C: 1.2 mL This amount falls short of the necessary dosage, as it does not meet the calculated requirement based on the infant's weight and prescribed daily dosage.
The primary healthcare provider (PHCP) prescribes 100 mL of 0.9% sodium chloride (normal saline) to infuse over two hours via intravenous microdrip tubing. The nurse sets the flow rate at how many drops per minute? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
50 drops per minute.
To determine the flow rate, the nurse calculates the total volume of 100 mL to be infused over 120 minutes. Dividing 100 mL by 120 minutes yields approximately 0.833 mL per minute. With microdrip tubing delivering 60 drops per mL, multiplying gives a flow rate of 50 drops per minute, aligning with the prescription.
A: 25 drops per minute. This calculation implies a significantly slower infusion rate, suggesting only 0.5 mL per minute, which does not meet the prescribed volume for proper hydration.
B: 75 drops per minute. This indicates a faster infusion rate, equating to 1.25 mL per minute, which would lead to administering the entire volume in less than the required two hours.
C: 100 drops per minute. This rate corresponds to a rapid infusion of 1.67 mL per minute, resulting in administering the volume in just over one hour, which contradicts the prescribed duration.
The nurse is caring for a client prescribed IV heparin. The client is prescribed 15 units/kg/hr. The client weighs 115.9 kg (254.8 lbs). The heparin is labeled with 25,000 units in 250 mL of D5W. How many mL/hr should this client receive? Fill in the blank. Record your answer using a whole number.
Rationale:
17 mL/hr
To determine the infusion rate, first calculate the total units required: 15 units/kg/hr x 115.9 kg = 1,738.5 units/hr. Then, using the concentration of heparin (25,000 units/250 mL), the required volume is calculated as follows: (1,738.5 units/hr) / (100 units/mL) = 17 mL/hr.
A: 10 mL/hr The calculation of 10 mL/hr does not meet the prescribed dosage, resulting in insufficient heparin administration for the client's weight and needs.
B: 25 mL/hr This volume exceeds the necessary dosage, potentially leading to an overdose of heparin and increasing the risk of adverse effects for the patient.
C: 12 mL/hr An infusion of 12 mL/hr falls short of the required units, leaving the patient underdosed and at risk for inadequate therapeutic effects.
The primary healthcare provider (PHCP) prescribes 0.375 mg of digoxin intravenously (IV) to a client. The nurse has 0.25 mg/mL of digoxin on hand. How many mL will the nurse administer? Fill in the blank. Record your answer using 1 decimal place.
Rationale:
1.5 mL
To determine the volume to administer, divide the prescribed dose of 0.375 mg by the concentration available, which is 0.25 mg/mL. This calculation shows that 1.5 mL is required to meet the prescription.
A: 0.5 mL The volume of 0.5 mL only provides 0.125 mg of digoxin, which is insufficient for the prescribed dosage of 0.375 mg.
B: 2.0 mL Administering 2.0 mL would equate to 0.5 mg of digoxin, exceeding the required dosage and potentially causing harm to the client.
C: 1.0 mL A volume of 1.0 mL delivers 0.25 mg of digoxin, which falls short of meeting the prescribed requirement of 0.375 mg.
The primary healthcare provider (PHCP) prescribes lidocaine at 2 mg/min. The medication label reads lidocaine 1 gram in 500 mL of 0.9% saline. How many mL per hour will the nurse administer to the client? Fill in the blank.
Rationale:
60 mL/hr. The calculation involves converting the prescribed rate of 2 mg/min to an hourly rate, resulting in 120 mg/hr. Given the solution concentration of 2 mg/mL, administering 60 mL/hr achieves the required dose.
A: 30 mL/hr. This rate does not provide the necessary medication amount, falling short of the prescribed 120 mg/hr required for effective treatment.
B: 90 mL/hr. Administering this volume would exceed the required dosage, resulting in an inappropriate delivery rate of lidocaine that could lead to toxicity.
C: 120 mL/hr. While this seems sufficient, it inaccurately doubles the necessary dose, posing a risk of overdosing the patient beyond the prescribed 2 mg/min rate.
The nurse is calculating intake for a client. The client received: ,¢ One 100 mL intravenous antibiotic ,¢ One eight-ounce cup of ice chips ,¢ One eight-ounce cup of coffee ,¢ One eight-ounce cup of ice cream ,¢ Three eight-ounce cups of water. The nurse should calculate the client's total intake as how many mL? Fill in the blank.
Rationale:
1080 mL
The total intake is calculated by converting all fluid amounts to milliliters. The client received 100 mL (antibiotic), 240 mL (ice chips), 240 mL (coffee), 240 mL (ice cream), and 720 mL (water), totaling 1080 mL.
A: 960 mL This total fails to include the correct conversion of all fluid types, especially the ice chips, coffee, and ice cream, which are underestimated in volume.
B: 1120 mL This option overestimates the total by incorrectly adding an excessive amount or miscalculating one of the individual fluid components included in the total intake.
C: 1000 mL This figure inaccurately sums the volumes, neglecting the precise calculations for ice chips and other fluids, resulting in a total that does not align with the correct intake.
After receiving a bolus of intravenous (IV) fluids, the infant's diaper weighs 35 grams (after subtracting dry diaper weight). How many mL of urine should the nurse record in the medical record? Fill in the blank.
Rationale:
35 mL
The 35 grams of urine produced by the infant corresponds directly to 35 mL, as the density of urine is approximately 1 g/mL. This direct correlation allows for accurate recording of the urine output based on the weight of the wet diaper.
A: 30 mL The measurement fails to account for the full weight of urine produced, underestimating the actual output recorded after the hydration from the IV fluids.
B: 40 mL This option overestimates the urine output, suggesting an excess volume that does not align with the diaper's actual weight measurement.
C: 25 mL This choice also undervalues the urine output, disregarding the accurate weight of the wet diaper post-urination in relation to fluid intake.
The primary healthcare provider (PHCP) prescribes one liter of 0.9% saline to infuse over 6 hours. How many mL per hour will the nurse administer to the client? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
167 mL/hr.
To calculate the infusion rate, divide the total volume of saline (1000 mL) by the infusion time (6 hours). This yields approximately 166.67 mL/hr, which rounds to 167 mL/hr, ensuring the client receives the prescribed amount accurately.
A: 200 mL/hr. This rate exceeds the necessary infusion speed, leading to potential complications and not adhering to the prescribed volume over the specified time.
B: 250 mL/hr. Administering this volume would result in delivering saline too rapidly, increasing the risk of fluid overload and associated adverse effects on the patient.
C: 120 mL/hr. This rate falls short of the required infusion rate, leaving the client under-treated and potentially delaying the intended therapeutic effects of the saline solution.
The primary healthcare provider (PHCP) prescribes 6,000 units of heparin subcutaneously. The vial reads 10,000 units/1 mL. How many milliliter(s) should the nurse administer? Fill in the blank. Round your answer using 1 decimal place.
Rationale:
0.6 mL
To administer 6,000 units of heparin, the nurse calculates the volume needed by using the concentration in the vial. Since the vial contains 10,000 units per mL, dividing 6,000 by 10,000 yields 0.6 mL, which is the correct dosage to administer.
A: 0.5 mL This option represents an insufficient dosage, as it would only deliver 5,000 units, failing to meet the prescribed amount of 6,000 units.
B: 0.7 mL Administering 0.7 mL would provide 7,000 units, exceeding the required dosage and potentially leading to an overdose of heparin.
C: 1.0 mL This choice delivers a full 10,000 units, significantly surpassing the prescribed 6,000 units and risking serious adverse effects from excessive heparin administration.
The nurse is caring for a client who is prescribed IV heparin. The client is prescribed 15 units/kg/hr. The client weighs 70 kgs (154 Ibs). The heparin is labeled with 25,000 units in 250 mL of D5W. How many mL/hr should this client receive? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
11 mL/hr
To calculate the required mL/hr of heparin, first determine the total units needed: 15 units/kg/hr × 70 kg = 1050 units/hr. Then, using the concentration of 25,000 units in 250 mL, find the infusion rate: (1050 units/hr ÷ 25,000 units) × 250 mL = 11 mL/hr.
A: 10 mL/hr The calculation for 10 mL/hr does not meet the required dosage of 1050 units/hour based on the client's weight, leading to inadequate medication delivery.
B: 12 mL/hr Administering 12 mL/hr exceeds the calculated requirement of 11 mL/hr, risking potential complications from heparin overdose and inadequate monitoring of therapeutic levels.
C: 9 mL/hr A dosage of 9 mL/hr falls short of the calculated 11 mL/hr, resulting in insufficient anticoagulation for the client’s treatment needs.
The primary healthcare provider (PHCP) prescribed azithromycin 500 mg daily for a client with sepsis. The medication label reads 500 mg of azithromycin mixed in 250 mL of 0.9% saline. The drop factor is 15. The nurse sets the flow rate at how many drops per minute? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
63 gtts/minute
To determine the flow rate, the formula used is (Volume in mL × Drop factor) / Time in minutes. Here, (250 mL × 15 gtts/mL) / 240 minutes equals 63 gtts/minute, providing the correct flow rate for the prescribed medication.
A: 50 gtts/minute This calculation underestimates the total drops by misapplying the volume or time, resulting in a lower flow rate that would not adequately deliver the medication.
B: 75 gtts/minute This figure suggests an excessively high flow rate, indicating a miscalculation of time or drop factor, which could lead to potential complications from administering the medication too rapidly.
C: 80 gtts/minute This option also indicates an overly accelerated drip rate, likely stemming from a misinterpretation of the necessary calculations, risking patient safety through rapid administration.
The primary healthcare provider (PHCP) prescribes 10 mg/kg of acetaminophen for a child weighing 13.18 kg (28.99 lbs). How many milligrams should the nurse administer to the child? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
132 mg. The calculation for the acetaminophen dosage involves multiplying the child's weight in kilograms (13.18 kg) by the prescribed dosage (10 mg/kg), resulting in 131.8 mg, which rounds to 132 mg.
A: 130 mg. This dosage miscalculates the weight-based requirement, rounding down instead of correctly rounding 131.8 mg to 132 mg, leading to an insufficient administration.
B: 135 mg. Administering this amount exceeds the necessary calculation, disregarding the precise weight-based formula, which can lead to potential dosage errors and unnecessary medication administration.
C: 120 mg. This choice underestimates the calculated dosage significantly, failing to apply the correct weight multiplier, which results in a substantial deficit in the medication amount needed for the child.
The primary healthcare provider prescribes 30 mL/kg of 0.9% saline to a client with suspected sepsis who weighs 107.27 kg (235.99 lbs). How many mL will the nurse administer to the client? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
3218 mL
To determine the volume of saline to administer, multiply the client's weight (107.27 kg) by the prescribed dosage (30 mL/kg). This results in 3218 mL, confirming the correct amount needed for treatment.
A: 3210 mL This value underestimates the calculated requirement by not accounting for the precise multiplication of the client's weight and the prescribed saline dosage.
B: 3300 mL This option exceeds the necessary calculation, suggesting an incorrect understanding of the weight-based saline dosing required for the client's treatment.
C: 3000 mL This amount significantly undervalues the calculation, failing to reflect the client's actual weight and the prescribed saline dosage accurately.
The primary healthcare provider (PHCP) prescribes a bolus of regular insulin prior to the nurse administering a continuous infusion. The prescription is for 0.1 units/kg. The client weighs 116.36 kg (255.99 lbs). How many units of insulin should the nurse administer to the client? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
12 units.
To calculate the insulin dosage, multiply the client's weight (116.36 kg) by the prescribed dose (0.1 units/kg). This results in 11.636 units, which rounds to 12 units. This ensures the client receives the appropriate bolus for effective management of their condition.
A: 11 units. Rounding down does not provide adequate insulin dosage, potentially compromising the effectiveness of the treatment and failing to meet the prescribed amount.
B: 13 units. Administering one extra unit exceeds the required dosage, risking potential adverse effects and not adhering to the precise medical guidelines set forth by the healthcare provider.
C: 10 units. This amount falls short of the calculated requirement, risking insufficient therapeutic response and failing to deliver the necessary insulin based on the client's weight.
The client is prescribed 3 g/hr of intravenous magnesium sulfate via continuous infusion. The label reads 20g of magnesium sulfate in 1000 mL of normal saline. How many mL/hr should the nurse set the pump to deliver the prescribed dose? Fill in the blank.
Rationale:
150 mL/hr. To determine the infusion rate, first find the concentration of magnesium sulfate: 20 g in 1000 mL equals 0.02 g/mL. To achieve 3 g/hr, dividing 3 g by 0.02 g/mL yields 150 mL/hr, confirming the correct infusion rate.
A: 200 mL/hr. This volume administers too much magnesium sulfate, exceeding the prescribed dose of 3 g/hr, which could lead to potential toxicity and adverse effects.
B: 100 mL/hr. This rate underdelivers the required magnesium sulfate, providing only 2 g/hr instead of the necessary 3 g/hr, resulting in inadequate treatment for the client.
C: 250 mL/hr. This calculation significantly overshoots the intended dosage, delivering 5 g/hr, which is far above the prescribed amount and poses risks of magnesium toxicity.
The primary healthcare provider (PHCP) prescribes 30 mg of phenobarbital by mouth, once daily. The nurse has phenobarbital 10 mg tablets on hand. How many tablet(s) per dose should the nurse administer to the client? Fill in the blank.
Rationale:
3 tablets
To achieve a prescribed dose of 30 mg of phenobarbital using 10 mg tablets, the nurse must administer three tablets. This total ensures that the client receives the accurate dosage recommended by the primary healthcare provider, thereby maximizing therapeutic effectiveness while adhering to safety protocols.
A: 1 tablet Administering just one tablet equates to a mere 10 mg, far below the prescribed 30 mg and insufficient for therapeutic effect.
B: 2 tablets Administering two tablets totals 20 mg, which still falls short of the necessary 30 mg dose, potentially compromising treatment effectiveness.
D: 4 tablets Providing four tablets results in 40 mg, exceeding the prescribed dosage and increasing the risk of adverse effects and toxicity for the client.
The nurse is caring for a client prescribed IV heparin. The client is prescribed 18 units/kg/hr. The client weighs 111.8 kg (245.96 Ibs). The heparin is labeled with 25,000 units in 250 mL of D5W. How many mL/hr should this client receive? Fill in the blank. Round to the nearest whole number.
Rationale:
20 mL/hr
To determine the required infusion rate, calculate the total units needed: 18 units/kg/hr multiplied by 111.8 kg equals 2004 units/hr. With 25,000 units in 250 mL, the rate is 20 mL/hr for the client.
A: 10 mL/hr This dosage underestimates the required rate significantly, leading to insufficient heparin delivery and ineffective anticoagulation for the client's weight and prescribed dosage.
B: 15 mL/hr This amount still falls short of the necessary infusion rate, which would not adequately meet the therapeutic requirement of heparin based on the client's weight.
C: 25 mL/hr This dosage exceeds the calculated requirement, posing a risk of heparin overdose and associated complications, particularly for a patient weighing 111.8 kg.
The nurse reviews the client's intake and output throughout the twelve-hour shift. ,¢ The client consumed three eight-ounce cups of water. ,¢ The client received 0.9% sodium chloride at 70 mL/hr for 12 hours. ,¢ The client received an infusion of 500 mg of azithromycin reconstituted in 250 mL of 0.9% sodium chloride to treat a bacterial infection. ,¢ The client received 5 mg of morphine sulfate diluted in 0.9% sodium chloride, totaling an infused volume of 7 mL. When calculating the total intake for the client for the shift, the nurse would document how many milliliters?
Rationale:
The total intake for the client for the shift is 1817 mL. The correct answer is derived by summing the client's water intake of 720 mL, the sodium chloride infusion of 840 mL, the azithromycin infusion of 250 mL, and the morphine infusion of 7 mL, totaling 1817 mL.
B: 1815 mL This option fails to account for the total volume of sodium chloride and other infusions accurately, leading to an underestimation of the client's actual intake.
C: 1810 mL This choice overlooks the precise calculation of the sodium chloride infusion and the additional volumes from medications, resulting in a significant discrepancy in the total intake.
D: 1800 mL This figure does not reflect the accurate sum of all liquid intakes, as it neglects several milliliters from the various infusions administered during the shift.
The primary healthcare provider (PHCP) prescribes 500 mL of 0.45% saline to be administered over one hour. The drop factor is 10 gtts/mL. How many drops per minute should the nurse set the flow rate at? Fill in the blank. Round your answer to the nearest whole number.
Rationale:
83 gtts/minute
To calculate the flow rate, divide the total volume (500 mL) by the time in minutes (60 minutes), yielding approximately 8.33 mL per minute. Multiplying by the drop factor (10 gtts/mL) gives 83 gtts/minute, which is the required flow rate for administering the saline solution effectively.
A: 100 gtts/minute Setting the flow rate at 100 gtts/minute exceeds the calculated requirement, resulting in an overly rapid infusion that could lead to potential complications for the patient.
B: 75 gtts/minute This rate underestimates the necessary flow, leading to insufficient saline administration that may delay therapeutic effects and compromise patient care during the prescribed time frame.
C: 90 gtts/minute Choosing 90 gtts/minute also overestimates the flow and could cause fluid overload, posing risks to the patient’s safety and breaching the prescribed guidelines for administration.
The nurse is caring for a client receiving a continuous infusion of heparin. The label reads 25,000 units of heparin in 500 mL of dextrose 5% in water (D5W). The client is receiving 1,500 units per hour. How many milliliters (mL) did the client receive in an eight-hour shift? Fill in the blank.
Rationale:
480 mL
The client receives 1,500 units per hour, totaling 12,000 units over eight hours. Since the infusion contains 25,000 units in 500 mL, the calculation reveals that 480 mL corresponds to 12,000 units.
A: 240 mL This volume represents only half of the correct total, indicating an underestimation of the units received over the full eight-hour shift.
B: 360 mL This choice inaccurately assumes a different hourly rate or duration, leading to a miscalculation of the total volume infused.
C: 600 mL This option exceeds the necessary volume, suggesting an incorrect interpretation of the client's hourly infusion rate over the specified time.
The primary healthcare provider (PHCP) prescribes magnesium sulfate at 2 grams/hour. The nurse has magnesium sulfate 20 grams in 500 mL of 0.9% saline on hand. How many mL per hour will the nurse administer? Fill in the blank.
Rationale:
50 mL/hr.
To determine the administration rate, first, find the concentration of magnesium sulfate in the solution: 20 grams in 500 mL corresponds to 40 grams per 1000 mL. Dividing 2 grams by 40 grams per 1000 mL gives 50 mL/hr, which is the required infusion rate to meet the PHCP's prescription.
A: 25 mL/hr Administration at this rate would provide only 1 gram of magnesium sulfate, falling short of the prescribed 2 grams per hour, making it insufficient.
B: 100 mL/hr This rate would deliver 4 grams of magnesium sulfate, exceeding the prescribed 2 grams per hour, which could potentially lead to toxicity or adverse effects.
C: 75 mL/hr Infusing at this rate results in 3 grams of magnesium sulfate per hour, surpassing the required dosage and posing risks associated with higher-than-prescribed amounts.
