EXAM 2 STUDY GUIDE
Exam 2 Study Guide for Class CLS-111
| Question | Answer |
|---|---|
| Mechanisms vs. Outcomes in Drug Classifications: Explain how therapeutic drug classifications differ from chemical classifications. | Difference: Drug categories are structured either by the chemical composition of the active ingredient or by how they treat a specific disease/symptom. |
| Using analgesics, anesthetics, and narcotics, explain how distinct chemical mechanisms of action can yield similar clinical therapeutic outcomes. | Analgesics: via prostaglandin inhibition without altering consciousness. Anesthetics: blocking neural impulse conduction locally or centrally. Narcotic analgesics: acting directly on central nervous system opioid receptors. |
| Furthermore, describe how a single drug (such as an antihypertensive) can operate through multiple chemical pathways. | A single drug can belong to multiple categories or accomplish a goal through diverse chemistry. Exp: antihypertensives lower blood pressure through calcium channel blocking, angiotensin inhibition, direct arterial relaxation, or heart rate reduction. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Analgesics | Inhibits prostaglandin synthesis; provides mild-to-moderate pain relief without loss of consciousness. Examples: Advil, naproxen, Celebrex, Tylenol. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Anesthetics | Blocks neural impulse conduction to produce local or general insensibility to pain. Examples: Lidocaine (Xylocaine), Novocaine, Desflurane. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Antibiotics | Kills or inhibits the growth of bacteria; completely ineffective against viral or fungal infections. Examples: Amoxil, Keflex, Zithromax, Cipro. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Anticoagulants | Inhibits the coagulation cascade and prevents blood clot formation; does not thin the physical viscosity of the blood. Examples: Heparin, Coumadin, Lovenox. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Antihypertensives | Reduces blood pressure by decreasing heart rate, dilating blood vessels, or reducing intravascular fluid volume. Examples: Lisinopril, Norvasc, Lopressor. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Antidepressants (specifically MAOIs) | Modifies brain neurotransmitter activity affecting mood. Caution: Requires close monitoring during initial therapy due to potential worsening of depression. Examples (MAOIs): Marplan, Nardil, Emsam. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Bronchodilators | Relaxes smooth muscle surrounding the bronchi to dilate airways; used for rescue or maintenance therapy. Examples: albuterol (Proventil), Isuprel. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Diuretics | Inhibits renal sodium reabsorption to increase urine excretion and decrease total fluid volume; used for hypertension, heart failure, and edema. Examples: Lasix, Diuril. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Vasodilators | Relaxes vascular smooth muscle to dilate vessels and lower blood pressure. Critical Warning: Concomitant use with sildenafil/tadalafil (Viagra/Cialis) causes a dangerous, potentially fatal drop in BP. Examples: nitroglycerin, Isordil. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Insulin | Facilitates cellular uptake of glucose to lower blood sugar levels. Divided into rapid-, short-, intermediate-, and long-acting forms. Examples: Lantus, Humulin. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Antihistamines | Competitively blocks 1 histamine receptor sites; prevents new allergic symptoms but cannot reverse an existing reaction already underway. Examples: Claritin, Benadryl, Zyrtec. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Antineoplastics | Disrupts malignant cell development and replication; highly toxic to rapidly dividing healthy tissue as well. Examples: Myleran, Cytoxan. |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Sedatives/Hypnotics | Depresses central nervous system activity; highly habit-forming. Critical Warning: Must never be combined with alcohol due to additive CNS depression. Examples: Seconal, Valium, Ambien |
| Detail the primary mechanism of action, therapeutic indications, specific clinical cautions/considerations, and brand/generic examples: o Fibrinolytics | Acts as a "clot-buster" to dissolve intravascular thrombi during acute emergency heart attacks or ischemic strokes; administered alongside anticoagulants. Examples: TNK, tPA. |
| Define and contrast the Chemotherapeutic drug action group. | Used to cure or control diseases caused by infectious organisms or neoplasia. Treats infections, allergic/autoimmune disorders, metabolic defects, cancers, poisonings, and mental illnesses by destroying microorganisms or inhibiting their reproduction. |
| Define and contrast the Pharmacodynamic drug action group. | Alters noninfectious physiological processes by acting directly on body systems, either suppressing excess hormone secretion or augmenting chemical deficiencies. |
| Define and contrast the Miscellaneous Agents drug action group. | Products not fitting the main categories, including specialized analgesics, smoking cessation agents, and antipsoriatics. |
| In your explanation, detail how pharmacodynamic agents utilize agonists, antagonists, and synergistic or additive drug combinations to treat noninfectious conditions. | Agonists: bind stimulate specific cellular receptors to trigger a response. Antagonists: block natural ligand binding. Synergistic/Additive drug: Combine drugs to produce an effect equal to or greater than the sum of their individual effects. |
| List and describe the key influencing factors that alter how a body responds to a medication. | Age, body weight, Body Surface Area, administration route, patient drug tolerance, developed true allergies, drug intolerance, and drug-drug or drug-food interactions. |
| Differentiate between local, remote, and systemic drug effects. | Local: Strictly restricted to the immediate anatomical area of application. Remote: Action occurs in tissue or organ systems distant from the site of administration. Systemic: Generalized throughout the entire body via circulatory distribution. |
| How does the route of administration impact the speed and sustained duration of drug delivery? | Injections enter systemic circulation fastest. Transdermal patches release medication slowly over time for sustained therapeutic levels. Pediatric, geriatric, and severely ill patients typically require reduced doses. |
| Differentiate among a drug name: Chemical | Details the precise molecular/atomic structure of the drug; used primarily by chemists and researchers (who assign a shorthand code for daily study). |
| Differentiate among a drug name: Generic | Assigned by the United States Adopted Names Council upon initial FDA approval. Generic drugs contain identical active ingredients as brand versions, but may contain different inert binders, coatings, or preservatives. |
| Differentiate among a drug name: Trade | Created and owned by the manufacturing drug company for commercial marketing; always capitalized. The proposed trade name must be formally approved by the FDA. |
| Explain the specific rules regarding capitalization, FDA approval, USAN Council assignment, and the non-compete patent protection period granted to manufacturers. | New trade-name drugs are granted a 7-year non-compete patent period to allow the developer to recover R&D expenses. |
| Explain why look-alike/sound-alike drug names represent a significant source of medication errors. | Look-alike and sound-alike drug names are a primary driver of adverse drug events and medication errors. |
| Identify the organization that publishes the List of Confused Drug Names in the Medication Safety Alert. | The Institute for Safe Medication Practices (ISMP) publishes the List of Confused Drug Names in the ISMP Medication Safety Alert. |
| Provide five specific pairs of easily confused medications | 1. Atarax \ Ativan 2. Benylin \ Benadryl 3. Diovan \ Zyban 4. Lamictal \ Lamisil 5. prochlorperazine \ trifluoperazine |
| Describe the clinical risk associated with EMR drop-down menus. | In Electronic Medical Record systems, alphabetically contiguous drugs appear adjacent to each other in drop-down selection menus. A single accidental click can substitute a completely different drug class. |
| Compare and contrast the regulatory oversight provided by the FDA for Prescription (Rx) drugs | Require a direct written order from a licensed prescriber. The FDA mandates rigorous pre-market testing to verify safety, active ingredients, clinical indications, and accurate packaging labels. |
| Compare and contrast the regulatory oversight provided by the FDA for Over the Counter (OTC) drugs | Deemed safe for general consumer use without provider oversight. Many OTC drugs are former Rx medications transitioned after proving low incidence of severe adverse effects. |
| Compare and contrast the regulatory oversight provided by the FDA for Dietary Supplements (vitamins, herbal, and alternative remedies) | Classified as dietary supplements and receive little to no FDA oversight, with zero mandatory manufacturing standards. |
| Why might a prescription medication be recalled even if it is inherently safe? | An FDA drug recall does not automatically mean a drug is toxic or dangerous; drugs are frequently recalled due to minor labeling inaccuracies or packaging errors. |
| What critical instruction must be given to patients taking herbal remedies? | Patients must disclose all herbal/supplement use. Supplements can duplicate Rx effects (causing toxicity) or neutralize them (causing treatment failure) and can distort diagnostic lab test conclusions. |
| Detail the Controlled Substances Act of 1970 and the role of the Drug Enforcement Administration (DEA). | The Controlled Substances Act of 1970 created the Drug Enforcement Administration (DEA) to regulate narcotics and control dangerous drugs. |
| Outline the abuse potential, recognized medical uses, prescription writing rules, emergency telephone order allowances, and refill restrictions for DEA Schedules I. | High potential for abuse; no recognized medical use in the U.S. Prescriptions are completely prohibited (research use only).

| Show all step-by-step mathematical work for the following calculation: Solve 528 ÷ 32. | (528 ÷ 32): Step 1: Divide 528 by 32 528 ÷ 32 = 16.5 Verification: 16.5 x 32 = 528 |
| Detail the essential steps a medical assistant must execute when verifying a prescription or medication order before administration or pharmacy transmission. | 1. Confirm patient ID using two identifiers 2. Verify Rx name against the order. 3. Check Rx dosage strength/form. 4. Calculate Rx count. 5. Screen for allergies/adverse effects. 6. Match Rx against the providers verbal/written order before filling. |
| What specific items must be verified, and what rule applies when information is uncertain or incomplete? | Never assume missing or unclear information. If any element of an order is uncertain, double-check and verify directly with the prescriber before proceeding. |
| Describe the step-by-step protocol for calling in a prescription to a community pharmacy, including information required and verbal verification requirements. | 1. State full name, title, and practice name. 2. Providers name and DEA number 3. Patient’s name, DOB, and phone number. 4. State complete drug details 5.

Order Entry: Select patient profile, search drug database, select correct drug, strength, and form, and input sig instructions and quantity. |
| Highlight automated clinical safety checks. | Automated Safety Screening: The EHR system automatically screens the entry against patient records for drug-drug interactions, allergies, and duplicate therapy, generating clinical warnings for provider review before electronic signing. |
| Distinguish between a clinical medication order and an outpatient prescription. | A prescription is a legal order issued to an outpatient retail pharmacy for self-administration by the patient. A medication order is an internal directive authorizing healthcare staff to administer a drug immediately within a clinical facility. |
| List all mandatory elements that must be included in a complete medication order. | 1. Patient’s full legal name. 2. Date and precise time the order is written. 3. Exact drug name and dosage. 4. Approved route of administration. 5. Frequency or exact scheduled time of administration. 6. Prescriber's legal signature. |
| List and define the core Rights of Medication Administration presented in clinical practice guidelines, focusing on specific procedural rules for dose calculation, route adherence, scheduled timing, documentation timing, and handling patient refusal. | Right Patient: Verify using 2 IDs Right Medication: Check label 3x Right Dose: Verify calculation Right Route: Rx is given by exact route Right Time: Give Rx @ correct time Right Documentation: Put Rx in EHR Right to Refuse: Legal right to decline |
| Define the following approved medical abbreviations: PO, IM, SubQ, q, prn, and stat. | PO = per os (by mouth) IM = intramuscular SubQ = subcutaneous q = every (e.g., q4h = every 4 hours) prn = as needed stat = immediately |
| Identify four dangerous, error-prone abbreviations prohibited by The Joint Commission and state the mandatory full phrase that must be written instead | 1. U or u (unit) - Write "unit" 2. IU (International Unit) - Write "International Unit" 3. QD / qd (daily) - Write "daily" 4. MS / MSO4 - Write full drug name "morphine sulfate" |
| Explain why parenteral injection routes achieve the fastest bloodstream concentration compared to oral or transdermal administration. | Injections (IM, SubQ) deliver medication directly into vascular tissue or subcutaneous fat beds, bypassing GI degradation and liver first-pass metabolism to achieve the fastest systemic bloodstream absorption. |
| Contrast the immediate absorption of injections with the time-release mechanism of transdermal patches | While injections deliver rapid peak concentrations, transdermal patches utilize a specialized membrane to deliver continuous, slow, time-released drug quantities over extended hours or days. |
| Identify how dosage requirements must be adjusted for pediatric, geriatric, or severely ill patients. | Pediatric patients, geriatric patients, and severely ill individuals possess altered metabolic and excretory capabilities; they consistently require reduced, carefully calculated dosages to avoid toxicity. |
| Outline the strict legal and procedural rules governing documentation immediately following an injection. | Administered injected medications and immunizations must be documented immediately after the procedure is completed. |
| Why must documentation never occur prior to administration? | Documenting prior to administration is a severe legal falsification error (the dose could be dropped, contaminated, or refused after recording). |
| Describe how a medical assistant must handle and document a patient's exercise of the right to refuse an injected medication or immunization. | If a patient exercises their right to refuse an injection/immunization: 1. Cease administration immediately. 2. Address and explore the patient's rationale/concerns. 3. Notify the provider. 4. Document the refusal and provider notification in EHR. |
