Practice: Medications

The short answer

Medications is 28 of the 80 scored questions across six knowledge areas. Two of them require reasoning across drugs rather than recalling a name.

Twenty-eight scored questions, and only some of them are the name-recall ones candidates drill for.

Four questions

Question 1

A patient is already taking a medication from a particular therapeutic class and is prescribed a second drug from the same class. What is this an example of?

  1. A drug interaction
  2. A therapeutic duplication
  3. An adverse effect
  4. A contraindication
Answer: B. Two drugs from the same therapeutic class treating the same condition is a therapeutic duplication. A drug interaction involves one drug affecting another's action or metabolism, which is a different mechanism. This distinction is a named knowledge area and the two terms are routinely swapped.
Question 2

Why is learning drugs by therapeutic class more useful than learning a list of names?

  1. Classes are shorter to memorize
  2. Two knowledge areas require reasoning across drugs, which classification supports
  3. Brand names are not examined
  4. The exam only asks about classes
Answer: B. Therapeutic duplications and drug interactions both require you to relate drugs to each other. A flat list of name pairs cannot support that. Option D is wrong because specific drugs certainly are examined, and option C is wrong because brand and generic names are used interchangeably.
Question 3

A medication requires refrigeration. Which knowledge area does a question about its handling fall under?

  1. Indications of medications
  2. Drug stability and proper storage
  3. Side effects and adverse effects
  4. Strengths and dosage forms
Answer: B. Drug stability and proper storage is its own named knowledge area within Medications, and it carries real weight in the outline. It is a small, finite, entirely learnable block covering refrigeration, protection from light and reconstituted stability, and it is worth a distinct study session.
Question 4

A patient reports a reaction to a drug. What distinguishes an allergy from a side effect?

  1. An allergy is more severe
  2. An allergy involves an immune response; a side effect is a pharmacological consequence
  3. A side effect is always predictable and an allergy never is
  4. There is no meaningful difference for a technician
Answer: B. The mechanism is the distinction: an allergy is immune-mediated, a side effect follows from how the drug acts. Severity is not the test, which makes option A the plausible wrong answer. Option D is wrong because the difference determines whether the drug can be used again.
Notice what these questions did not ask

None required recalling a specific brand-generic pair. Name recall is one of six knowledge areas; the other five ask you to do something with the names. Preparation that is entirely flashcards prepares for a sixth of this domain.

What to study

  • Classes, with one indication and one common adverse effect each
  • The distinction between duplication and interaction
  • Storage, as a separate small block
  • Allergy against side effect, as a mechanism rather than a severity

Common questions

How many Medications questions are on the PTCE?

28 of the 80 scored questions, across six knowledge areas.

What is a therapeutic duplication?

Two drugs from the same therapeutic class treating the same condition.

How does that differ from an interaction?

An interaction involves one drug affecting another's action or metabolism.

What separates an allergy from a side effect?

An allergy is immune-mediated; a side effect follows from how the drug acts. Severity is not the test.

Are flashcards enough for this domain?

No. Name recall is one of six knowledge areas.
