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 A
Explanation
To set the IV pump correctly, you need to calculate the following:
- The patient's weight in kilograms
- The dose of Zofran in milligrams
- The infusion rate in milliliters per hour
First, convert the patient's weight from pounds to kilograms by dividing by 2.2:
176 lb / 2.2 = 80 kg
Next, multiply the patient's weight by the dose of Zofran per kilogram to get the total dose in milligrams:
80 kg x 0.15 mg/kg = 12 mg
Then, use the formula for infusion rate to find how many milliliters per hour the IV pump should deliver:
Infusion rate (mL/h) = (Total volume (mL) x Flow factor (gt/mL)) / Time (min) x 60 min/h
Since the medication is mixed in 50 mL of normal saline and the infusion time is 15 minutes, plug in these values into the formula:
Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 15 min x 60 min/h
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 200 mL/h
Correct Answer is D
Explanation
This answer is correct because it is based on a series of unit conversions and calculations. The nurse should follow these steps to provide safe medication to the child:
1) Convert the child's weight from pounds to kilograms by dividing by 2.2, since there are 2.2 lbs in 1 kg. The child weighs 20 kg.
2) Multiply the prescribed dose per kilogram by the child's weight in kilograms to get the total dose in milligrams. The child needs 40 mg of pyrimethamine.
3) Use the ratio given on the drug label to convert the total dose in milligrams to the volume in milliliters. The nurse can set up a proportion as follows:
1 mg / 5 mL = 40 mg / x mL
Cross-multiplying and solving for x gives:
x = 200 mL
Therefore, the nurse should administer 200 mL of medication to deliver 40 mg of pyrimethamine to the child.
4) Convert the volume in milliliters to the volume in teaspoons by dividing by 5, since there are 5 mL in 1 tsp. The nurse should administer 40 tsp of medication to the child.
5) Convert the volume in teaspoons to the volume in cups by dividing by 48, since there are 48 tsp in 1 cup. The nurse should administer 0.83 cups of medication to the child.
