Expiration date
Beyond use date (Correct answer)
Prescription date
Compounding date

Correct answer: Beyond use date

When a medication is repackaged or compounded by the pharmacy, it is assigned a 'beyond use date' (BUD) rather than the original manufacturer's expiration date. The BUD is typically shorter than the manufacturer's date and reflects the stability of the drug once it has been altered from its original container. This ensures the medication remains effective and safe for the patient after manipulation.

Question 8: Insurance companies enact plan limitations to control drug use, which of the following is a limitation for a mail order pharmacy for days’ supply?

30
60
90 (Correct answer)
120

Correct answer: 90

Many insurance companies implement plan limitations to control costs and drug utilization, particularly for mail-order pharmacies. A common limitation for mail-order prescriptions is a 90-day supply. This allows patients to receive a larger quantity of maintenance medications at once, often with the benefit of a reduced co-pay, while still managing overall drug expenditures.

Question 9: Which of the following is a disadvantage to implementing pharmacy information systems?

Enhanced patient safety
Increased workflow efficiency
Enhanced delivery of patient-sensitive information
Barriers in accessing different databases. (Correct answer)

Correct answer: Barriers in accessing different databases.

While pharmacy information systems offer numerous benefits, a significant disadvantage can be the barriers in accessing and integrating data from different databases or healthcare systems. This lack of interoperability can hinder comprehensive patient care. It creates challenges in sharing vital information across various healthcare providers, potentially impacting treatment coordination.

Question 10: Which of the following is not an organ in the lymphatic system?

Thymus
Thyroid (Correct answer)
Tonsil
Spleen

Correct answer: Thyroid

The lymphatic system is a vital part of the immune system, comprising organs such as the thymus, spleen, and tonsils, which produce and store lymphocytes and filter lymph. The thyroid gland, however, is an endocrine gland responsible for producing hormones that regulate metabolism. It is not considered an organ of the lymphatic system.

Question 11: A physician with a DEA number starting with “X” represents?

Mid-level practitioner
Hospital practitioner
Opioid treating practitioner (Correct answer)
Dental practitioner

Correct answer: Opioid treating practitioner

A DEA registration number starting with 'X' indicates that the practitioner is authorized to prescribe buprenorphine for the treatment of opioid use disorder. This specific prefix is assigned to practitioners who have met the requirements to become an 'Opioid Treating Practitioner' under the Drug Addiction Treatment Act of 2000 (DATA 2000). This designation ensures specialized training for treating addiction.

Question 12: A patient will receive 100 mg/kg of ampicillin per day. What is the total daily dose for a 40-pound patient?

182 mg
18.2 g
1.8 g (Correct answer)
0.182 g

Correct answer: 1.8 g

First, convert the patient's weight from pounds to kilograms: 40 lbs / 2.2 lbs/kg = 18.18 kg. Next, calculate the total daily dose in milligrams: 100 mg/kg * 18.18 kg = 1818 mg. Finally, convert milligrams to grams: 1818 mg / 1000 mg/g = 1.818 g, which rounds to 1.8 g. This calculation ensures accurate dosing based on body weight.

Question 13: A drug's dose is 250 micrograms per kilogram of body weight. What dosage should be given to a 55-pound child?

6.25 mg (Correct answer)
12.5 mcg
12.5 mg
6.25 mcg

Correct answer: 6.25 mg

First, convert the child's weight from pounds to kilograms: 55 lbs / 2.2 lbs/kg = 25 kg. Next, calculate the total dose in micrograms: 250 mcg/kg * 25 kg = 6250 mcg. Finally, convert micrograms to milligrams: 6250 mcg / 1000 mcg/mg = 6.25 mg. This precise calculation ensures the correct dosage for pediatric patients.

Question 14: In 25 mL of normal saline, how much sodium chloride is there?

225 mg (Correct answer)
225 mcg
225 g
2.25g

Correct answer: 225 mg

Normal saline is a 0.9% sodium chloride solution, meaning there are 0.9 grams of sodium chloride per 100 mL of solution. To find the amount in 25 mL, set up a proportion: (0.9 g / 100 mL) = (x g / 25 mL). Solving for x gives x = 0.225 g, which converts to 225 mg (since 1 g = 1000 mg). This calculation is fundamental for preparing IV solutions.

Question 15: An IV drip rate of 30 drips per minute is set. If there are 15 drops per ml, what is the infusion rate in ml/hr?

30ml/hr
40 ml/hr
270ml/hr
120 ml/hr (Correct answer)

Correct answer: 120 ml/hr

First, calculate the mL per minute: (30 drops/min) / (15 drops/mL) = 2 mL/min. Then, convert mL per minute to mL per hour: 2 mL/min * 60 min/hr = 120 mL/hr. This calculation is essential for setting the correct infusion rate for IV medications, ensuring patients receive the prescribed volume over the intended time.

Question 16: In the morning, the doctor prescribes Humulin Lente U-100 insulin #10ml, 36 units subcutaneous injection. How much is the daily supply?

20 days
27 days
30 days
28 days (Correct answer)

Correct answer: 28 days

A 10 mL vial of U-100 insulin contains 100 units/mL, totaling 1000 units (10 mL * 100 units/mL). If the patient uses 36 units per day, the total supply in days is 1000 units / 36 units/day = 27.77 days. Given the options, 28 days is the closest and most practical dispensing quantity, often rounded to ensure a full dispensing period.
