The healthcare provider prescribes magnesium hydroxide 4800 mg by mouth at bedtime for a client with constipation. The bottle is labeled 'Magnesium hydroxide Saline Laxative, USP 400 mg per 5 mL.' How many ounces should the nurse instruct the client to take with each dose? (Enter numerical value only.)

Correct Answer: 2

Rationale: The correct answer is 2 ounces. To find the answer, we can use the following steps: Calculate the volume of magnesium hydroxide in mL by dividing the dose in mg by the concentration in mg/mL. Convert the volume in mL to ounces by multiplying by 0.0338. Round the result to the nearest whole number. Using these steps, we get: (volume in mL) = (4800) / (400) = 12 mL. (volume in ounces) = (12) x (0.0338) = 0.4056 ounces. (rounded volume in ounces) = 2 ounces. Therefore, the nurse should instruct the client to take 2 ounces of magnesium hydroxide Saline Laxative, USP with each dose.

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.

The healthcare provider prescribes metoclopramide 7.5 mg/mL IM every 3 hours PRN vomiting for a client who is receiving chemotherapy. The nurse prepares an injection using a 2 mL prefilled syringe cartridge labeled, 'metoclopramide 5 mg/mL.' How many mL should the nurse administer?(Enter numeric value only. If rounding is required, round to the nearest tenth.)

Correct Answer: 1.5

Rationale: The correct answer is 1.5 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) = (7.5) / (5). Simplifying, we get: (mL to be administered) = 1.5. Therefore, the nurse should administer 1.5 mL of metoclopramide from the prefilled syringe cartridge to the client.

The healthcare provider prescribes filgrastim 5 mcg/kg/day subcutaneously for a client who weighs 132 pounds and has just completed chemotherapy. The medication is available in 480 mcg/0.8 mL. How many mL should the nurse administer?(Enter numerical value only. If rounding is required, round to the nearest tenth.)

Correct Answer: 0.5

Rationale: To find the answer, we can use the following steps: Convert the client'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) = (132) / (2.2) = 60 kg. (dose in mcg) = (5) x (60) = 300 mcg. (volume in mL) = (300) / (480 / 0.8) = 0.5 mL. (rounded volume in mL) = 0.5 mL. Therefore, the nurse should administer 0.5 mL of filgrastim to the client.

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 client with human immunodeficiency virus (HIV) begins active labor at 38 weeks gestation and receives a prescription for zidovudine 2 mg/kg IV, to be administered over 1 hour. The client weighs 185 lbs. Based on the client's weight, how many mg should the nurse prepare to administer? (Enter numerical value only. If rounding is required, round to the nearest whole number.)

Correct Answer: 168

Rationale: To find the answer, we can use the following steps: Convert the client's weight from pounds to kilograms by dividing by 2.2. Multiply the weight in kilograms by the dosage in mg/kg. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (185) / (2.2) = 84.091 kg. (dose in mg) = (2) x (84.091) = 168.182 mg. (rounded dose in mg) = 168 mg. Therefore, the nurse should prepare to administer 168 mg of zidovudine IV to the client.
