Question 1 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.
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 liraglutide 1.2 mg subcutaneously daily for a client with type 2 diabetes mellitus. The liraglutide Pen contains 18 mg of liraglutide and will deliver doses of 0.6 mg, 1.2 mg, or 1.8 mg. When teaching the client about the use of the liraglutide Pen, how many doses should the nurse tell the client is available in each Pen? (Enter the numerical value only.)
Correct Answer: 15
Rationale:
To find the answer, we can use the following formula: (number of doses) = (amount of liraglutide in Pen) / (dose of liraglutide prescribed). Substituting the given values, we get: (number of doses) = (18) / (1.2). Simplifying, we get: (number of doses) = 15.
Therefore, the nurse should tell the client that each liraglutide Pen contains 15 doses of liraglutide.
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.
