18 Pharmacology & Patient Care Practice Questions & Answers

1. 1. As a drug class, what do anticoagulants primarily do?

   • A.Kill or inhibit bacteria
   • B.Lower blood pressure by relaxing vessels
   • C.Reduce the blood's ability to clot✓ Answer
   • D.Relieve pain and reduce fever

   Anticoagulants interfere with the blood-clotting cascade, so they reduce the blood's ability to form clots and are used to prevent conditions like deep vein thrombosis and stroke. Lowering blood pressure, killing bacteria, and relieving pain describe other drug classes.

2. 2. A patient's chart lists a class of drugs used to treat high blood pressure. Which class is that?

   • A.Antihypertensives✓ Answer
   • B.Bronchodilators
   • C.Antibiotics
   • D.Analgesics

   Antihypertensives are the class specifically indicated to lower elevated blood pressure. Bronchodilators open airways, analgesics relieve pain, and antibiotics treat bacterial infection, so none of those target blood pressure.

3. 3. Bronchodilators are a class of medication used mainly to:

   • A.Increase urine output
   • B.Fight fungal infections
   • C.Open the airways to ease breathing✓ Answer
   • D.Thin the blood

   Bronchodilators relax the smooth muscle around the bronchi, widening the airways so air moves more easily, which is why they treat asthma and COPD. Increasing urine output is a diuretic effect and thinning the blood is an anticoagulant effect.

4. 4. What is the primary therapeutic action of a diuretic?

   • A.Increases excretion of water and sodium in urine✓ Answer
   • B.Blocks histamine release
   • C.Neutralizes stomach acid
   • D.Slows the heart rate directly

   Diuretics act on the kidneys to increase the excretion of water and sodium, reducing fluid volume, which helps treat edema and hypertension. Neutralizing acid and blocking histamine are the actions of antacids and antihistamines respectively.

5. 5. Which class of drugs is used specifically to treat bacterial infections?

   • A.Diuretics
   • B.Anticoagulants
   • C.Antibiotics✓ Answer
   • D.Analgesics

   Antibiotics kill bacteria or stop their growth and are indicated only for bacterial infections, not viral ones. Analgesics relieve pain, diuretics increase urine output, and anticoagulants reduce clotting, so none of those treat infection.

6. 6. A sublingual medication is administered by:

   • A.Swallowing it with water
   • B.Placing it under the tongue to dissolve✓ Answer
   • C.Applying it to the skin surface
   • D.Injecting it into a muscle

   Sublingual administration places the drug under the tongue, where the rich blood supply lets it absorb directly into the bloodstream and bypass first-pass liver metabolism for rapid effect. Swallowing, injecting, and skin application describe oral, parenteral, and topical routes.

7. 7. Which term describes any medication given by injection?

   • A.Enteral
   • B.Topical
   • C.Inhalation
   • D.Parenteral✓ Answer

   Parenteral routes deliver medication by injection (for example intramuscular, subcutaneous, or intravenous), bypassing the digestive tract. Enteral means via the GI tract, topical is on the skin, and inhalation is through the lungs.

8. 8. Which route generally provides the fastest absorption of a medication into the bloodstream?

   • A.Topical
   • B.Intravenous✓ Answer
   • C.Transdermal patch
   • D.Oral

   The intravenous route delivers the drug directly into the vein and thus the bloodstream, so no absorption step is needed and onset is fastest. Oral, topical, and transdermal routes must first cross tissue barriers, which slows absorption.

9. 9. A metered-dose inhaler delivers medication by which route?

   • A.Inhalation✓ Answer
   • B.Oral
   • C.Sublingual
   • D.Parenteral

   An inhaler delivers medication as a fine mist into the lungs, so it uses the inhalation route, which is ideal for respiratory drugs acting directly on airway tissue. Oral is swallowed, sublingual is under the tongue, and parenteral is by injection.

10. 10. 'Right patient' as one of the rights of medication administration is best verified by:

    • A.Using two identifiers such as name and date of birth✓ Answer
    • B.Relying on the room number alone
    • C.Asking the person in the next chair
    • D.Recognizing the patient's face

    Confirming identity with at least two independent identifiers, such as full name and date of birth, is the accepted safety standard because it prevents look-alike or same-room mix-ups. A room number, a neighbor's word, or face recognition can all be wrong.

11. 11. After giving a medication, which 'right' requires the medical assistant to record it in the chart?

    • A.Right time
    • B.Right route
    • C.Right dose
    • D.Right documentation✓ Answer

    Right documentation requires recording the medication only after it is actually given, so the record reflects what truly happened and prevents duplicate dosing. Right dose, route, and time are verified before administration, not recorded afterward.

12. 12. Before administering any ordered medication, the medical assistant should first:

    • A.Ask the patient to sign a waiver
    • B.Double the dose to be safe
    • C.Check the patient's allergy history✓ Answer
    • D.Warm the medication

    Checking the allergy history before administration prevents a potentially life-threatening allergic reaction, so it is a required safety step. Warming a drug is not routinely needed, waivers are not a substitute for safety checks, and changing a dose is outside the MA's authority.

13. 13. Why do medication-safety programs discourage the abbreviation 'U' for 'units'?

    • A.It can be misread as a zero or the number four, causing overdose✓ Answer
    • B.It is too long to write quickly
    • C.It applies only to liquid medications
    • D.It is only valid in metric countries

    The abbreviation 'U' can be mistaken for a 0 or a 4 when handwritten, which can turn a dose like 4U into 40 and cause a serious overdose, so 'units' should be written out. The other statements are not the reason it appears on error-prone abbreviation lists.

14. 14. On a medication label, the strength of the drug tells you:

    • A.The amount of active ingredient per unit or volume✓ Answer
    • B.The color of the tablet
    • C.The name of the manufacturer
    • D.How the drug should be stored

    Strength states how much active ingredient is present per tablet, capsule, or volume, which is essential for confirming the right dose. Color, manufacturer, and storage are other label details but do not define potency.

15. 15. When teaching a patient how to take a new medication, the best way to confirm they understood is to:

    • A.Assume understanding if they do not ask questions
    • B.Have the patient explain the instructions back in their own words✓ Answer
    • C.Ask 'Do you understand?' and accept a yes
    • D.Hand them a brochure and move on

    The teach-back method, having the patient restate instructions in their own words, verifies genuine understanding and reveals gaps, which a simple yes/no question cannot. Handouts and assumptions do not confirm that the message was actually understood.

16. 16. Within a medical assistant's scope of practice, who must first order or prescribe a medication?

    • A.A licensed provider such as a physician✓ Answer
    • B.The receptionist
    • C.The patient
    • D.The medical assistant

    A medical assistant may only administer a medication after a licensed provider (such as a physician) has ordered or prescribed it, because prescribing is outside the MA's scope of practice. The MA, receptionist, and patient cannot legally issue that order.

17. 17. In dosage vocabulary, the term 'dose' refers to:

    • A.The total supply in the bottle
    • B.The amount of medication given at one time✓ Answer
    • C.The time between two doses
    • D.The way the drug enters the body

    A dose is the quantity of medication administered at a single time, which is distinct from the total supply, the interval between doses (frequency), and the route. Confusing these terms can lead to medication errors.

18. 18. What is the general characteristic of the oral route of administration compared with the intravenous route?

    • A.Cannot be used for tablets or capsules
    • B.Requires sterile technique and a needle
    • C.Faster onset and immediate full effect
    • D.Slower onset but generally more convenient and safer✓ Answer

    The oral route requires the drug to be swallowed and absorbed through the GI tract, so onset is slower than IV, but it is non-invasive, convenient, and generally safer with a lower risk of severe immediate reactions. IV, not oral, needs sterile technique and a needle.
