Question 1 of 5
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.
Question 2 of 5
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.
Question 3 of 5
The healthcare provider prescribes heparin 1,400 units/hour intravenously (IV). The IV bag contains heparin 20,000 units in 250 mL dextrose 5% in water. How many mL/hour should the nurse program the infusion pump to deliver?(Enter numeric value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 17
Rationale: The correct answer is 17 mL/hour.
To find the answer, we can use the following formula: (mL/hour) = (units/hour) x (mL per unit). Substituting the given values, we get: (mL/hour) = (1,400) x (250 / 20,000). Simplifying, we get: (mL/hour) = (1,400) x (0.0125). (mL/hour) = 17.5. (rounded mL/hour) = 17.
Therefore, the nurse should program the infusion pump to deliver 17 mL/hour of heparin in dextrose 5% in water.
Question 4 of 5
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.
Question 5 of 5
A 4-year-old is admitted with croup and receives a prescription for a single dose of dexamethasone 0.6 mg/kg IM. The child weighs 35 pounds. How many mg should the nurse administer? (Enter numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 10
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. 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) = (35) / (2.2) = 15.909. (dose in mg) = (0.6) x (15.909) = 9.545. (rounded dose in mg) = 10.
Therefore, the nurse should administer 10 mg of dexamethasone to the child.
