Pharmacy & Pharmacology makes up 7 of every 50 questions on a Tigertest VTNE practice test. Here are 10 of the 28 questions on it, each with the answer and the reason.
Updated by the Tigertest team. Based on the AAVSB VTNE content outline approved March 2023. The real exam passes on a scaled score of 425; 70% here is a practice target.
1. A 20 kg dog is prescribed 2.2 mg/kg of a drug supplied at 50 mg/mL. What volume is drawn up?
- A.2.2 mL
- B.0.88 mL
- C.0.44 mL
- D.1.76 mL
Answer: B. 2.2 mg/kg times 20 kg is 44 mg, and 44 mg divided by 50 mg/mL is 0.88 mL. Dividing the dose by the weight instead of multiplying gives the 0.44 mL error.
2. A 15 kg dog needs 10 mg/kg of a drug available as 50 mg tablets. How many tablets are given per dose?
- A.6 tablets
- B.0.5 tablet
- C.1.5 tablets
- D.3 tablets
Answer: D. 10 mg/kg times 15 kg is 150 mg, and 150 divided by 50 mg per tablet is 3 tablets.
3. How many milligrams of lidocaine are in 1 mL of a 2 percent solution?
- A.20 mg
- B.0.2 mg
- C.2 mg
- D.200 mg
Answer: A. A percent solution is grams per 100 mL, so 2 percent is 2 g per 100 mL, or 20 mg per mL. Multiply the percent by 10 to get mg/mL.
4. A 44 lb dog is dosed at 5 mg/kg. What is the dose in milligrams?
- A.50 mg
- B.10 mg
- C.100 mg
- D.220 mg
Answer: C. 44 lb divided by 2.2 is 20 kg, and 20 kg times 5 mg/kg is 100 mg. Multiplying by the weight in pounds gives the 220 mg overdose.
5. A 250 mg capsule is prescribed every 12 hours for 14 days. How many capsules are dispensed?
- A.42 capsules
- B.56 capsules
- C.28 capsules
- D.14 capsules
Answer: C. Every 12 hours is 2 doses per day, and 2 times 14 days is 28 capsules. Counting one per day gives 14 and counting every 6 hours gives 56.
6. A 10 kg dog receives a constant rate infusion at 2 mcg/kg per minute. How much drug is delivered per hour?
- A.1,200 mcg per hour
- B.120 mcg per hour
- C.12,000 mcg per hour
- D.20 mcg per hour
Answer: A. 2 mcg/kg per minute times 10 kg is 20 mcg per minute, and 20 times 60 minutes is 1,200 mcg (1.2 mg) per hour. Forgetting to multiply by 60 gives 20.
7. How is 50 mL of a 1 percent solution prepared from a 10 percent stock?
- A.25 mL of stock plus 25 mL of diluent
- B.10 mL of stock plus 40 mL of diluent
- C.1 mL of stock plus 49 mL of diluent
- D.5 mL of stock plus 45 mL of diluent
Answer: D. C1V1 = C2V2: 10 percent times V1 equals 1 percent times 50 mL, so V1 is 5 mL of stock, made up to 50 mL with 45 mL of diluent.
8. Which drug is a Schedule II controlled substance under federal law?
- A.Ketamine
- B.Hydromorphone
- C.Butorphanol
- D.Phenobarbital
Answer: B. Hydromorphone, morphine, fentanyl, methadone and oxymorphone are Schedule II: accepted medical use with a high abuse potential. Butorphanol and phenobarbital are Schedule IV and ketamine is Schedule III.
9. Under federal law, ketamine is in which controlled substance schedule?
- A.Schedule I
- B.Schedule III
- C.Schedule II
- D.Schedule IV
Answer: B. Ketamine and buprenorphine are Schedule III. Schedule I drugs have no accepted medical use, and Schedule II covers the full opioid agonists such as morphine and hydromorphone.
10. Butorphanol and diazepam share which federal schedule?
- A.Schedule III
- B.Schedule V
- C.Schedule II
- D.Schedule IV
Answer: D. Butorphanol, tramadol, the benzodiazepines (diazepam, midazolam, alprazolam) and phenobarbital are Schedule IV. Schedule V is the lowest, such as some codeine cough preparations.
