Which of the following medications should be administered whole (e.g., not divided or crushed for administration)?
A capsule
A scored tablet
An unscored tablet
A lozenge
The Correct Answer is D
A lozenge is a type of medication that is designed to dissolve slowly in the mouth, usually to treat sore throat, cough, or oral infections. It should not be divided or crushed for administration because it may alter its effectiveness, taste, or absorption. It should also not be swallowed whole because it may cause choking or irritation.
A capsule is a type of medication that consists of a gelatin shell enclosing a powder or liquid. It can be opened and sprinkled on soft food or mixed with water for administration unless it is an extended-release or enteric-coated capsule.
A scored tablet is a type of medication that has a groove or indentation on its surface to facilitate breaking into equal halves or quarters. It can be divided along the score line for administration unless it is an extended-release or enteric-coated tablet.
An unscored tablet is a type of medication that does not have a groove or indentation on its surface. It can be crushed or cut into smaller pieces for administration unless it is an extended-release or enteric-coated tablet.

Correct Answer is B
Explanation
To find the rate in mL/hr, you need to use the formula for infusion rate:
Infusion rate (mL/h) = Total volume (mL) / Time (h)
Since the total volume is 500 mL and the time is 2 hours, plug in these values into the formula:
Infusion rate (mL/h) = 500 mL / 2 h
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 250 mL/h
Therefore, the nurse should set the IV pump to deliver **250 mL/h** to infuse LR 500 mL over 2 hours.
Correct Answer is A
Explanation
The flow rate of infusion is 125 mL/hr.
This answer is correct because it is based on a simple division and rounding calculation. The nurse should follow these steps to determine the flow rate of infusion:
1) Subtract the start time of the infusion from the end time of the infusion to get the duration of the infusion in hours and minutes, as follows:
15:45 - 06:57 = 8:48
Therefore, the infusion lasted for 8 hours and 48 minutes.
2) Convert the duration of the infusion to hours only by dividing the minutes by 60, since there are 60 minutes in 1 hour. Add this to the hours, as follows:
8 + (48 / 60) = 8.8
Therefore, the infusion lasted for 8.8 hours.
3) Divide the volume of the infusion by the duration of the infusion to get the flow rate in milliliters per hour, as follows:
1000 mL / 8.8 hr = 113.64 mL/hr
Therefore, the flow rate is 113.64 mL/hr.
4) Round the flow rate to the nearest whole number, as follows:
113.64 mL/hr ≈ 114 mL/hr
Therefore, the flow rate is approximately 114 mL/hr.
5) Adjust the flow rate to a standard value that can be set on an IV pump or gravity drip chamber, as follows:
114 mL/hr → 125 mL/hr
Therefore, the flow rate of infusion is 125 mL/hr.
