Question 1 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.
Question 2 of 5
A client receives a prescription for amoxicillin 2 g/clavulanate 125 mg by mouth every 12 hours for 10 days. The medication is available in 1000 mg/62.5 mg extended release tablets. How many tablets should the nurse administer?(Enter numerical value only.)
Correct Answer: 2
Rationale:
To find the answer, we can use the following steps: Calculate the number of tablets needed to provide the prescribed dose of amoxicillin by dividing the dose in mg by the amount of amoxicillin in one tablet. Calculate the number of tablets needed to provide the prescribed dose of clavulanate by dividing the dose in mg by the amount of clavulanate in one tablet. Compare the two numbers and choose the larger one as the number of tablets to be administered. Using these steps, we get: (number of tablets for amoxicillin) = (2000) / (1000) = 2. (number of tablets for clavulanate) = (125) / (62.5) = 2. (number of tablets to be administered) = max(2, 2) = 2.
Therefore, the nurse should administer 2 tablets of amoxicillin/clavulanate to the client.
Question 3 of 5
The healthcare provider prescribed 2 liters of 5% Dextrose in water (D5W) to infuse in 24 hours. The IV administration set delivers 15 gtt/mL. How many mL/hour should the nurse program the infusion pump? (Enter numeric 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: (mL/hour) = (mL/minute) x 60. Substituting the given values, we get: (mL/hour) = (2000 / 24) x 60. Simplifying, we get: (mL/hour) = 83.333. (rounded mL/hour) = 83.
Therefore, the nurse should program the infusion pump to deliver 83 mL/hour of D5W.
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 child is to receive vancomycin 40 mg/kg intravenously one hour before a scheduled procedure. The child weighs 44 pounds. How many mg of the medication should the nurse administer? (Enter numeric value only.)
Correct Answer: 800
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) = (44) / (2.2) = 20. (dose in mg) = (40) x (20) = 800. (rounded dose in mg) = 800.
Therefore, the nurse should administer 800 mg of vancomycin to the child.
