Question 1 of 5
The nurse is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D2.5W, 0.45% NS) at 45 mL/hour for a child with dehydration. The nurse attaches a volume-control administration set with a microdrip chamber to the bag of solution. How many microdrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)
Correct Answer: 45
Rationale:
To find the answer, we can use the following formula: (microdrops/minute) = (mL/hour) x (microdrops/mL) / 60. Substituting the given values, we get: (microdrops/minute) = (45) x (60) / 60. Simplifying, we get: (microdrops/minute) = 45.
Therefore, the nurse should regulate the infusion to deliver 45 microdrops/minute of Dextrose 2.5% in 0.45% Sodium Chloride.
Question 2 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 3 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 4 of 5
The healthcare provider prescribes ceftazidime 30 mg/kg/day for an infant weighing 3,500 grams. What dose should the nurse administer daily to this infant? (Enter numeric value only.)
Correct Answer: 105
Rationale:
To find the answer, we can use the following steps: Convert the infant's weight from grams to kilograms by dividing by 1000. Multiply the weight in kilograms by the dosage in mg/kg/day. Round the result to the nearest whole number. Using these steps, we get: (weight in kg) = (3,500) / (1000) = 3.5 kg. (dose in mg/day) = (30) x (3.5) = 105 mg/day. (rounded dose in mg/day) = 105 mg.
Therefore, the nurse should administer 105 mg of ceftazidime daily to this infant.
Question 5 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.
