Question 1 of 5
The healthcare provider prescribes a hydration infusion of normal saline to run over 3 hours at 30 mL/kg for a client who is dehydrated and weighs 70 kg. The nurse should program the infusion pump to deliver how many mL/hour?(Enter numeric value only.)
Correct Answer: 700
Rationale:
To find the answer, we can use the following steps: Calculate the total volume of normal saline in mL by multiplying the weight in kg by the dosage in mL/kg. Divide the total volume of normal saline in mL by the number of hours to get the rate in mL/hour. Round the result to the nearest whole number. Using these steps, we get: (total volume in mL) = (30) x (70) = 2100 mL. (rate in mL/hour) = (2100) / (3) = 700 mL/hour. (rounded rate in mL/hour) = 700 mL/hour.
Therefore, the nurse should program the infusion pump to deliver 700 mL/hour of normal saline.
Question 2 of 5
A client receives a prescription for 1 liter of lactated Ringer's intravenously (IV) to be infused over 8 hours. The IV administration set delivers 20 gtt/mL. How many gtt/min should the nurse regulate the infusion? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 42
Rationale:
To find the answer, we can use the following formula: (gtt/min) = (mL/hour) x (gtt/mL) / 60. Substituting the given values, we get: (gtt/min) = (1000 / 8) x (20) / 60. Simplifying, we get: (gtt/min) = 125 x 20 / 60. (gtt/min) = 41.667. (rounded gtt/min) = 42.
Therefore, the nurse should regulate the infusion to deliver 42 gtt/minute of lactated Ringer's.
Question 3 of 5
Penicillin G procaine 240,000 units intramuscularly is prescribed for a 4-year-old child who has a streptococcal respiratory infection. The medication vial is labeled 1,200,000 units/2 mL. How many mL should the nurse administer?(Enter numeric value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.4
Rationale:
To find the answer, we can use the following formula: (mL to be administered) = (units prescribed) / (units per mL). Substituting the given values, we get: (mL to be administered) = (240,000) / (1,200,000 / 2). Simplifying, we get: (mL to be administered) = (240,000 x 2) / (1,200,000). (mL to be administered) = 480,000 / 1,200,000. (mL to be administered) = 0.4.
Therefore, the nurse should administer 0.4 mL of penicillin G procaine to the child.
Question 4 of 5
A client receives a prescription for 1 liter of lactated Ringer's intravenously (IV) to be infused over 12 hours. The IV administration set delivers 60 gtt/mL. How many gtt/min should the nurse regulate the infusion?(Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 83
Rationale:
To find the answer, we can use the following formula: (gtt/min) = (mL/hour) x (gtt/mL) / 60. Substituting the given values, we get: (gtt/min) = (1000 / 12) x (60) / 60. Simplifying, we get: (gtt/min) = 83.333. (rounded gtt/min) = 83.
Therefore, the nurse should regulate the infusion to deliver 83 gtt/minute of lactated Ringer's.
Question 5 of 5
A client with a gram-positive bacterial skin infection is receiving daptomycin 500 mg IV every 24 hours. The pharmacy delivers a secondary infusion of 0.9% Sodium Chloride with daptomycin 500 mg/100 mL to be infused in 30 minutes. How many mL/hour should the nurse program the infusion pump?(Enter the numerical value only.)
Correct Answer: 200
Rationale: The correct answer is 200 mL/hour.
To find the answer, we can use the following formula: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (100 / 30) x 60. Simplifying, we get: (mL/hour) = 3.333 x 60. (mL/hour) = 200.
Therefore, the nurse should program the infusion pump to deliver 200 mL/hour of daptomycin in 0.9% Sodium Chloride.
