A nurse is preparing to administer risperidone 5 mg PO.
Available is risperidone 2 mg tablets.
How many tablets should the nurse administer? (Round the answer to the nearest tenth, Use a leading zero if it applies.
Do not use a trailing zero).
2 tablets.
2.5 tablets.
2.6 tablets.
3 tablets.
The Correct Answer is B
The nurse should administer 2.5 tablets.
To determine the number of tablets needed to administer a dose of 5 mg using 2 mg tablets, you can divide the desired dose (5 mg) by the available tablet strength (2 mg/tablet): 5 mg ÷ 2 mg/tablet = 2.5 tablets.
Choice A is incorrect because administering 2 tablets would only provide a dose of 4 mg (2 tablets x 2 mg/tablet = 4 mg).
Choice C is incorrect because administering 2.6 tablets would provide a dose of 5.2 mg (2.6 tablets x 2 mg/tablet = 5.2 mg).
Choice D is incorrect because administering 3 tablets would provide a dose of 6 mg (3 tablets x 2 mg/tablet = 6 mg).

Correct Answer is C
Explanation
The nurse should set the flow rate to deliver 40 gtts/min.
This can be calculated by multiplying the infusion rate (120 mL/hr) by the drop factor (60 gtt/mL) and then dividing by the number of minutes in an hour (60 min/hr): (120 mL/hr) * (60 gtt/mL) / (60 min/hr) = 120 gtt/min
Choice A is not the best answer because setting the flow rate to deliver 20 gtts/min would not provide the desired infusion rate of 120 mL/hr.
Choice B is not the best answer because setting the flow rate to deliver 30 gtts/min would not provide the desired infusion rate of 120 mL/hr.
Choice D is not the best answer because setting the flow rate to deliver 50 gtts/min would provide a higher infusion rate than desired.
