Dive into practice questions

Question 1

A veterinarian prescribes methimazole for a cat with hyperthyroidism, but the owner reports the cat is impossible to pill. Which of the following is the most appropriate and commonly used compounded formulation to improve adherence in this scenario?

  1. A flavored oral chewable treat.
  2. A transdermal gel applied to the pinna (inner ear flap).
  3. An injectable formulation for subcutaneous administration.
  4. A sterile ophthalmic solution.

Question 2

Which of the following medications is strictly prohibited from extra-label use in any food-producing animal due to the risk of causing aplastic anemia in humans?

  1. Penicillin G
  2. Ivermectin
  3. Chloramphenicol
  4. Meloxicam

Question 3

A pharmacist is compounding a potassium bromide oral solution for a dog with epilepsy. Which of the following sweeteners must be avoided when formulating medications for canine patients due to the risk of inducing severe, life-threatening hypoglycemia?

  1. Sucrose
  2. Glycerin
  3. Sorbitol
  4. Xylitol

Question 4

When compounding a suspension for a reptile, what is a critical consideration regarding the choice of vehicle or flavor?

  1. Using a sugar-based syrup to improve taste is always recommended.
  2. Most reptiles have a poor sense of taste, so flavoring is not necessary.
  3. Alcohol-based vehicles are preferred for better absorption.
  4. Vehicles should be chosen carefully as some reptiles cannot metabolize sugars or certain glycols effectively.

Answer Key

  • Question 1: B. A transdermal gel applied to the pinna (inner ear flap). (Transdermal methimazole is a very common and effective compounded preparation for cats that are difficult to medicate orally, allowing the owner to apply the medication to the skin of the ear for absorption.)
  • Question 2: C. Chloramphenicol. (The FDA has explicitly banned the use of chloramphenicol in food animals because its residue can cause idiosyncratic aplastic anemia in susceptible humans, a serious public health risk.)
  • Question 3: D. Xylitol. (Xylitol is extremely toxic to dogs. It causes a rapid, potent release of insulin, leading to profound hypoglycemia, which can result in seizures, liver failure, and death.)
  • Question 4: D. Vehicles should be chosen carefully as some reptiles cannot metabolize sugars or certain glycols effectively. (Reptilian metabolism is very different from mammals. Sugar-heavy syrups or vehicles like propylene glycol can be harmful. Simple vehicles like water or vegetable oil are often safer choices.)
