Certified Medical Assistant Pharmacology for Medical Assistants Questions and Answers — Questions and Answers
Question 1: A medical assistant is preparing to administer a medication. To ensure patient safety, which of the following is NOT considered one of the 'Seven Rights' of medication administration?
- Right Provider (Correct answer)
- Right Patient
- Right Dose
- Right Route
Correct answer: Right Provider
The 'Seven Rights' of medication administration are Right Patient, Right Medication, Right Dose, Right Route, Right Time, Right Documentation, and Right Reason. While the medical assistant must ensure the medication was ordered by an authorized provider, 'Right Provider' is not traditionally listed as one of the core 'Seven Rights' that are checked immediately before administration.
Question 2: A provider orders a tuberculin skin test (TST) for a patient. The medical assistant should prepare to administer the purified protein derivative (PPD) solution via which of the following routes?
- Intramuscular (IM)
- Subcutaneous (SC)
- Intravenous (IV)
- Intradermal (ID) (Correct answer)
Correct answer: Intradermal (ID)
Intradermal (ID) injections are administered into the dermis, just below the epidermis. This route has the longest absorption time of all parenteral routes, which is necessary for diagnostic tests like tuberculin (PPD) and allergy testing, where the reaction needs to be observed locally on the skin.
Question 3: A patient arrives at the clinic with a prescription for a Schedule II medication. Which of the following is a key characteristic of drugs in this category?
- They have no accepted medical use.
- They have a high potential for abuse and dependence. (Correct answer)
- They can be refilled up to five times in six months.
- They are available over-the-counter.
Correct answer: They have a high potential for abuse and dependence.
According to the Drug Enforcement Administration (DEA), Schedule II drugs have a currently accepted medical use but possess a high potential for abuse, which may lead to severe psychological or physical dependence. Examples include many opioid analgesics and stimulants.
Question 4: The study of how the body absorbs, distributes, metabolizes, and excretes a drug is known as:
- Pharmacodynamics
- Pharmacotherapeutics
- Pharmacokinetics (Correct answer)
- Toxicology
Correct answer: Pharmacokinetics
Pharmacokinetics is the branch of pharmacology that deals with what the body does to a drug. It encompasses the processes of absorption, distribution, metabolism, and excretion (ADME).
Question 5: A medical assistant is instructed to administer 0.5 mL of a vaccine to a 4-year-old child. According to best practices for pediatric intramuscular injections, which of the following sites is most appropriate?
- Dorsogluteal
- Deltoid
- Vastus Lateralis (Correct answer)
- Ventrogluteal
Correct answer: Vastus Lateralis
The vastus lateralis muscle, located on the anterolateral aspect of the thigh, is the preferred site for intramuscular injections in infants and young children because it is well-developed and lacks major nerves and blood vessels. The deltoid is an option for older children, but the vastus lateralis is generally safer for a 4-year-old.
Question 6: Which part of a prescription contains the instructions for the pharmacist, including information on dispensing and any refill authorizations?
- Inscription
- Signa (Sig)
- Subscription (Correct answer)
- Superscription
Correct answer: Subscription
The subscription part of a prescription provides directions to the pharmacist. This includes the quantity of the drug to dispense, instructions for compounding if necessary, and the number of authorized refills.
