Question 1 of 5
A nurse is preparing to administer clindamycin 900 mg by intermittent IV bolus over 30 min. Available is clindamycin 900 mg in 100 mL dextrose 5% (DW). The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the infusion rate in mL/hr for administering clindamycin 900 mg in 100 mL dextrose 5% over 30 minutes, you would use the formula: (
Total Volume in mL / Time in hours) = Rate in mL/hr. Since the medication needs to be administered over 30 minutes, you convert 30 minutes into hours, which is 0.5 hours. Using the formula, you get (100 mL / 0.5 hours) = 200 mL/hr.
Question 2 of 5
A nurse is preparing an in-service program about preventing medication errors when transcribing a prescription. The nurse is using a dosage example of two tenths of a milligram. Which of the following examples should the nurse use to show appropriate transcription of this dosage?
Correct Answer: D
Rationale: 0.2 mg is the correct way to transcribe two tenths of a milligram without using trailing zeros, which reduces the risk of medication errors.
Question 3 of 5
A nurse is preparing to administer lorazepam 1 mg PO at bedtime. The amount available is lorazepam 2 mg tablets. How many tablets should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 0.5
Rationale:
To administer the correct dose of lorazepam, which is 1 mg, when only 2 mg tablets are available, the nurse should administer half a tablet. This is because each tablet contains 2 mg of lorazepam, and the prescribed dose is 1 mg.
Question 4 of 5
A nurse is caring for a client who is in Buck's traction. Which of the following actions should the nurse take? (Select all that apply.)
Correct Answer: B,C,D
Rationale: Monitoring peripheral pulses helps assess circulation and neurovascular status in the affected extremity. Examining the skin under the traction splint is essential to assess for skin integrity and prevent complications like pressure ulcers. Assessing the temperature of the affected extremity helps detect signs of circulatory impairment or infection.
Question 5 of 5
A nurse is preparing to administer 0.9% sodium chloride IV infusion 1-L bag at a rate of 200 mL/hr for a client who has rhabdomyolysis. The nurse should expect the IV pump to infuse over how many hours? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale:
To calculate the infusion time for a 1-L bag of 0.9% sodium chloride at a rate of 200 mL/hr, you would divide the total volume of the IV bag by the hourly infusion rate. Since there are 1000 mL in a 1-L bag, you would calculate 1000 mL divided by 200 mL/hr, which equals 5 hours.
