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
Correct Answer
B. In the pharmacy roomExplanation
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.Rate this question:

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
Correct Answer
A. 3 gExplanation
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.Rate this question:

What is the final volume when diluting 10ml of a lidocaine 6% nasal spray to a lidocaine 2% nasal spray?
- A.
12 ml
- B.
30 ml
- C.
15 ml
Correct Answer
B. 30 mlExplanation
To dilute the lidocaine nasal spray from 6% to 2%, a larger volume of diluent needs to be added. This means that the final volume will be greater than the initial volume of 10ml. Therefore, the correct answer is 30 ml.Rate this question:

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
Correct Answer
C. A want listExplanation
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.Rate this question:

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
Correct Answer
A. In refrigeratorExplanation
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.Rate this question:

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
Correct Answer
C. 1.5 mlExplanation
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.Rate this question:

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
Correct Answer
B. 33 gtts/minExplanation
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.Rate this question:

Ampules are made of __________.
- A.
Plastic
- B.
Glass
- C.
H2o content
Correct Answer
B. GlassExplanation
Ampules are typically made of glass because glass is a non-reactive material that can withstand high temperatures and is impermeable to air and moisture. This makes it ideal for storing and preserving sensitive substances such as medications or chemicals. Plastic is not commonly used for ampules as it is more prone to chemical reactions and can be permeable to gases and liquids. H2O content does not make sense as ampules are not made of water.Rate this question:

All chemotherapy drugs and waste must be disposed of in a __________.
- A.
Red biohazard container
- B.
Yellow biohazous disposal container
- C.
Trash can
Correct Answer
B. Yellow biohazous disposal containerExplanation
Chemotherapy drugs are hazardous substances that can pose a risk to human health and the environment if not disposed of properly. The use of a yellow biohazard disposal container ensures that these drugs and their waste are segregated and disposed of safely. The color yellow is commonly associated with biohazard materials, indicating the need for special handling and disposal procedures. This helps to prevent accidental exposure and contamination, protecting both healthcare workers and the general public. A yellow biohazard disposal container is the appropriate choice for the disposal of chemotherapy drugs and waste.Rate this question:

A child weighs 47.9 kg. What is his weight in pounds?
- A.
106 LBS
- B.
23 LBS
- C.
105 LBS
Correct Answer
C. 105 LBSExplanation
To convert kilograms to pounds, we can use the conversion factor of 1 kilogram = 2.20462 pounds. Therefore, to find the weight in pounds, we multiply the weight in kilograms (47.9 kg) by the conversion factor.
47.9 kg * 2.20462 pounds/kg = 105.79 pounds
So, the child's weight in pounds is approximately 105 pounds.Rate this question:

Zantac is classified as:
- A.
Antibiotic
- B.
Anti-depressant
- C.
H2 blocker
Correct Answer
C. H2 blockerExplanation
Zantac is classified as an H2 blocker. This is because Zantac, also known as ranitidine, works by blocking the histamine H2 receptors in the stomach, which reduces the production of stomach acid. H2 blockers are commonly used to treat conditions such as gastroesophageal reflux disease (GERD), ulcers, and heartburn. They provide relief by reducing the amount of acid produced in the stomach, helping to alleviate symptoms and promote healing.Rate this question:

Correct Answer
A. 4 chambersExplanation
The heart is composed of four chambers: two atria and two ventricles. The atria receive blood from the body and lungs, while the ventricles pump the blood out to the rest of the body. This division of chambers allows for efficient and coordinated pumping of blood throughout the circulatory system.Rate this question:

- C.
Muscle spasm
Correct Answer
B. Heart attackExplanation
Myocardial infarction is another term for a heart attack. It occurs when there is a blockage in one of the coronary arteries, which supply oxygen-rich blood to the heart muscle. This blockage leads to the death of a portion of the heart muscle, resulting in a heart attack. Symptoms may include chest pain, shortness of breath, and nausea. Prompt medical attention is crucial to prevent further damage and improve outcomes.Rate this question:

Warfarin’s active ingredient is the same ingredient found in what household product?
- A.
Rat poison
- B.
Clorax
- C.
Dish soap
Correct Answer
A. Rat poisonExplanation
Warfarin's active ingredient is the same ingredient found in rat poison. This is because warfarin is an anticoagulant that works by inhibiting the synthesis of vitamin K, which is necessary for blood clotting. Rat poison also contains anticoagulant chemicals that prevent blood from clotting, leading to internal bleeding and eventually death in rodents. Therefore, the active ingredient in warfarin and rat poison is the same, making rat poison the correct answer.Rate this question:

What does a Hydrophobic mean?
- A.
Fail to mix with water
- B.
Tendency to mix well with water
- C.
Tendency to mix well with alcohol
Correct Answer
A. Fail to mix with waterExplanation
Hydrophobic refers to the property of substances that fail to mix with water. This means that hydrophobic substances repel or do not dissolve in water. They tend to be nonpolar or have nonpolar regions, which do not interact favorably with the polar molecules of water. As a result, hydrophobic substances separate from water and form distinct phases or clusters. This behavior is commonly observed in oils, fats, and certain organic compounds that do not have an affinity for water.Rate this question:
