### After opening Xalantin, an eye medication used to treat glaucoma, where should the drug be stored?

• A.

In the refrigerator

• B.

In the pharmacy room

• C.

In the freezer

B. In the pharmacy room
Explanation
The drug should be stored in the pharmacy room because it is a medication that needs to be accessible to the pharmacist for dispensing to patients. Storing it in the refrigerator or freezer may not be appropriate as it could affect the stability and efficacy of the medication. Additionally, the pharmacy room is typically kept at controlled room temperature, which is suitable for storing most medications.

### How many grams are in 600ml of a 1:200 (w/v) solution of a drug?

• A.

3 g

• B.

0.3 g

• C.

30 g

A. 3 g
Explanation
A 1:200 (w/v) solution means that there is 1 gram of the drug in 200 ml of solution. To find the amount of grams in 600 ml of solution, we can set up a proportion: 1 gram/200 ml = x grams/600 ml. Cross-multiplying, we get 200x = 600, and solving for x gives us x = 3 grams. Therefore, there are 3 grams in 600 ml of the solution.

### A common name for an inventory process that relies on pharmacy staff to write down items to be reordered is:

• A.

A formulary system

• B.

Bar-coding

• C.

A want list

C. A want list
Explanation
A want list is a common name for an inventory process that relies on pharmacy staff to write down items to be reordered. This system allows staff members to manually identify and record the items that need to be restocked, ensuring that the pharmacy maintains an adequate inventory of necessary supplies. Unlike bar-coding or a formulary system, which involve more automated processes, a want list relies on the observation and judgment of pharmacy staff to determine what items are needed.

### If the storage condition for Xalantan solution indicates to store the drug between 0 to 5 degree celcius, one should store the drug:

• A.

In refrigerator

• B.

At room temp

• C.

In freezer

A. In refrigerator
Explanation
The correct answer is "In refrigerator" because the storage condition for Xalantan solution indicates that it should be stored between 0 to 5 degrees Celsius. The refrigerator provides a controlled and stable temperature within this range, making it the ideal storage location to maintain the drug's stability and effectiveness. Storing it at room temperature or in the freezer may lead to temperature fluctuations that could potentially degrade the drug.

### The physician orders Lanoxin (digoxin) 0.375 mg IV now. The label reads 500 mcg in 2 mL. How many mL will the patient receive?

• A.

0.15 ml

• B.

0.0015 ml

• C.

1.5 ml

C. 1.5 ml
Explanation
The physician has ordered Lanoxin (digoxin) 0.375 mg IV. The label on the medication states that there are 500 mcg (micrograms) in 2 mL. To determine the amount of mL the patient will receive, we need to convert the ordered dose from milligrams to micrograms. Since 1 mg is equal to 1000 mcg, 0.375 mg is equal to 375 mcg. Now we can set up a proportion to find the amount of mL: 500 mcg/2 mL = 375 mcg/x mL. Cross-multiplying and solving for x, we find that x = 1.5 mL. Therefore, the patient will receive 1.5 mL of Lanoxin.

### Your patient has an order to infuse 100 ml of D51/2NS with 10MEq of KCl over the next thirty minutes. The set calibration is 10gtt/ml. What is the correct rate of flow for this patient? ___________ gtts/min

• A.

3.33 gtts/min

• B.

33 gtts/min

• C.

0.3 gtts/min

B. 33 gtts/min
Explanation
The correct rate of flow for this patient is 33 gtts/min. This can be calculated by dividing the total volume to be infused (100 ml) by the time of infusion (30 minutes) and then multiplying by the drop factor (10 gtts/ml). This calculation results in 33 gtts/min.
