Question 1 of 5
A client with a gram-positive bacterial skin infection is receiving daptomycin 500 mg IV every 24 hours. The pharmacy delivers a secondary infusion of 0.9% Sodium Chloride with daptomycin 500 mg/100 mL to be infused in 30 minutes. How many mL/hour should the nurse program the infusion pump?(Enter the numerical value only.)
Correct Answer: 200
Rationale: The correct answer is 200 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) = (100 / 30) x 60. Simplifying, we get: (mL/hour) = 3.333 x 60. (mL/hour) = 200.
Therefore, the nurse should program the infusion pump to deliver 200 mL/hour of daptomycin in 0.9% Sodium Chloride.
Question 2 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 3 of 5
A client returns from the PACU with a bag of IV fluids that has 630 mL remaining in the 1,000 mL bag. The prescription reads, 'Continue the present IV over the next 7 hours.' The IV administration set delivers 10 gtt/mL. The nurse should regulate the infusion to deliver how many drops/minute to accomplish the new prescription? (Enter numeric value only.)
Correct Answer: 15
Rationale:
To find the answer, we can use the following steps: Calculate the infusion rate in mL/hour by dividing the volume of IV fluids by the time of infusion. Calculate the infusion rate in mL/minute by dividing the infusion rate in mL/hour by 60. Multiply the infusion rate in mL/minute by the drop factor in gtt/mL to get the infusion rate in gtt/minute. Round the result to the nearest whole number. Using these steps, we get: (infusion rate in mL/hour) = (630) / (7) = 90 mL/hour. (infusion rate in mL/minute) = (90) / (60) = 1.5 mL/minute. (infusion rate in gtt/minute) = (1.5) x (10) = 15 gtt/minute. (rounded infusion rate in gtt/minute) = 15.
Therefore, the nurse should regulate the infusion to deliver 15 gtt/minute of IV fluids to the client.
Question 4 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 5 of 5
A client with a gram-positive bacterial skin infection is receiving daptomycin 500 mg IV every 24 hours. The pharmacy delivers a secondary infusion of 0.9% Sodium Chloride with daptomycin 500 mg/100 mL to be infused in 30 minutes. How many mL/hour should the nurse program the infusion pump?(Enter the numerical value only.)
Correct Answer: 200
Rationale: The correct answer is 200 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) = (100 / 30) x 60. Simplifying, we get: (mL/hour) = 3.333 x 60. (mL/hour) = 200.
Therefore, the nurse should program the infusion pump to deliver 200 mL/hour of daptomycin in 0.9% Sodium Chloride.
