A patient receives a prescription for hydrocortisone sodium succinate 150 mg intravenously STAT. The powdered medication needs to be reconstituted with 2 mL of bacteriostatic water that will provide a solution of 250 mg/mL. How many mL should the nurse administer?(Enter numerical value only.)
Correct Answer: 0.6
Rationale: 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) = (150) / (250). Simplifying, we get: (mL to be administered) = 0.6. Therefore, the nurse should administer 0.6 mL of hydrocortisone sodium succinate to the patient.

The nurse plans to administer a bolus dose of IV Heparin based on the client's weight. The prescribed bolus dose is 100 units/kg. The client weighs 198 pounds. How many units of Heparin should the nurse administer? (Enter numeric value only.)
Correct Answer: 9000
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 units/kg. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (198) / (2.2) = 90 kg. (dose in units) = (100) x (90) = 9000 units. (rounded dose in units) = 9000 units. Therefore, the nurse should administer 9000 units of IV Heparin to the client.
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 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.
A client receives a prescription for ganciclovir 375 mg intravenously (IV) every 12 hours to infuse over 90 minutes. The pharmacy delivers ganciclovir 375 mg in a 150 mL IV bag. How many mL/hour should the nurse program the infusion pump?(Enter a whole number only.)
Correct Answer: 100
Rationale: The correct answer is 100 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) = (150 / 90) x 60. Simplifying, we get: (mL/hour) = 1.667 x 60. (mL/hour) = 100. Therefore, the nurse should program the infusion pump to deliver 100 mL/hour of ganciclovir in IV bag.
A patient with a renal calculi receives a prescription for an intravenous infusion of 0.9% Sodium chloride Injection, USP 1,000 mL to be infused over 2.5 hours. The nurse should program the infusion pump to deliver how many mL/hour?(Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 400
Rationale: To find the answer, we can use the following formula: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (1000 / 150) x 60. Simplifying, we get: (mL/hour) = 6.667 x 60. (mL/Hour) = 400. Therefore, the nurse should program the infusion pump to deliver 400 mL/hour of 0.9% Sodium chloride Injection, USP to the patient.
