PTCE Medications 1 — Questions and Answers
Question 1: Which of the following is an example of a medication classification that is used to treat bacterial infections?
- Antiviral
- Antifungal
- Antibiotic (Correct answer)
- Antihypertensive
Correct answer: Antibiotic
Antibiotics are a specific class of antimicrobial drugs designed to kill or inhibit the growth of bacteria. They are used to treat bacterial infections and are distinct from antivirals (for viruses), antifungals (for fungi), or antihypertensives (for high blood pressure).
Question 2: Which of the following is a common dosage form for oral medications?
- Injectable solution
- Oral tablet (Correct answer)
- Topical ointment
- Intranasal spray
Correct answer: Oral tablet
Oral tablets are a very common and convenient dosage form for medications intended to be swallowed and absorbed through the gastrointestinal tract. Other options like injectable solutions, topical ointments, and intranasal sprays represent different routes of administration, not typical oral forms.
Question 3: What is the primary purpose of a medication's half-life?
- To determine how long the drug stays in the body (Correct answer)
- To measure how effective the drug is
- To indicate the drug's strength
- To calculate the dosage of the drug
Correct answer: To determine how long the drug stays in the body
A medication's half-life is a pharmacokinetic parameter that measures the time it takes for the concentration of the drug in the body to be reduced by half. This is crucial for determining how long a drug's effects will last and how frequently it needs to be dosed to maintain therapeutic levels.
Question 4: Which of the following medications is most likely to cause an allergic reaction in patients?
- Penicillin (Correct answer)
- Acetaminophen
- Ibuprofen
- Metformin
Correct answer: Penicillin
Penicillin is widely recognized as one of the most common causes of drug allergies, with a significant portion of the population reporting hypersensitivity reactions. While other medications can cause allergies, penicillin's high incidence makes it a critical consideration in patient history.
Question 5: What is the correct method of administration for a transdermal patch?
- Place the patch on the tongue
- Apply the patch to the skin (Correct answer)
- Inject the patch into the bloodstream
- Insert the patch into the eye
Correct answer: Apply the patch to the skin
A transdermal patch is specifically designed for transdermal administration, meaning the medication is absorbed through the skin into the bloodstream. Therefore, the correct method is to apply the patch directly to the skin, allowing for systemic absorption over time.
