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.

Filgrastim 5 mcg/kg/day subcutaneous is prescribed for a child with cancer who weighs 88 pounds. The medication is labeled 300 mcg/mL. How many mL should the nurse administer daily to this child?(Enter the numerical value only. If rounding required, round to the nearest tenth.)
Correct Answer: 0.7
Rationale: To find the answer, we can use the following steps: Convert the child's weight from pounds to kilograms by dividing by 2.2. Calculate the dose of filgrastim in mcg by multiplying the weight in kg by the dosage in mcg/kg/day. Divide the dose in mcg by the concentration of filgrastim in mcg/mL. Round the result to the nearest tenth. Using these steps, we get: (weight in kg) = (88) / (2.2) = 40 kg. (dose in mcg) = (5) x (40) = 200 mcg. (volume in mL) = (200) / (300) = 0.667 mL. (rounded volume in mL) = 0.7 mL. Therefore, the nurse should administer 0.7 mL of filgrastim to this child daily.
The healthcare provider prescribes streptomycin 200 mg intramuscularly every 12 hours. The vial is labeled, 'Streptomycin 1 gram/2.5 mL.' How many milliliters should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 0.5
Rationale: The correct answer is 0.5 mL. To find the answer, we can use the following formula: (mL to be administered) = (mg prescribed) / (mg per mL). Substituting the given values, we get: (mL to be administered) = (200) / (1000 / 2.5). Simplifying, we get: (mL to be administered) = (200) x (2.5 / 1000). (mL to be administered) = 0.5. Therefore, the nurse should administer 0.5 mL of streptomycin from the vial to the client.
A patient receives a prescription for warfarin 2 mg IM daily. The pharmacy delivers a vial labeled, warfarin 5 mg/single-use vial. The instructions read, reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL. How many mL should the nurse administer?(Enter the numerical value only.)
Correct Answer: 1
Rationale: First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin. Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula: Amount of solution = amount of water + amount of warfarin. Substituting the given values, we get: Amount of solution = 2.7 + 5 = 7.7 mL. Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula: mL of solution = mg of warfarin / concentration of warfarin. Substituting the given values, we get: mL of solution = 2 / 2 = 1 mL. Therefore, the nurse should administer 1 mL of solution to the patient.
The nurse is caring for a client with an oral temperature of 100.6 F. What temperature in Celsius should the nurse document in the medical record? (Enter numerical value only. If rounding is required, round to the nearest tenth.)
Correct Answer: 38.1
Rationale: To find the answer, we can use the following formula: (Celsius) = (Fahrenheit - 32) x (5 / 9). Substituting the given value, we get: (Celsius) = (100.6 - 32) x (5 / 9). Simplifying, we get: (Celsius) = 68.6 x (5 / 9). (Celsius) = 38.111. (rounded Celsius) = 38.1. Therefore, the nurse should document the oral temperature as 38.1 C in the medical record.
The nurse plans to provide the next shift with the IV fluid balance for a client who had a 440 mL secondary infusion that was started 2 hours ago at a rate of 85 mL/hour via an infusion pump. What is the remaining volume to be infused? (Enter numeric value only.)
Correct Answer: 270
Rationale: To find the answer, we can use the following formula: (remaining volume) = (initial volume) - (infused volume). Substituting the given values, we get: (remaining volume) = (440) - ((85 x 2)). Simplifying, we get: (remaining volume) = (440) - (170). (remaining volume) = 270. Therefore, the remaining volume to be infused is 270 mL.
