Certified Medical Assistant (CMA AAMA) flashcards

The process of ranking patients for care based on the urgency and severity of their condition.

• Life-threatening symptoms (chest pain, difficulty breathing) are highest priority
• Stable, non-urgent complaints are seen last
• Triage decisions protect patient safety and clinic efficiency

Memory trick: 'Chest pain trumps the rest of the pack.'

A left lateral position with the top leg sharply flexed, used for rectal exams, enemas, and vaginal exams in patients unable to tolerate lithotomy.

• Patient lies on left side, left arm behind body
• Right knee flexed sharply toward chest
• Used for rectal temperature, enemas, and proctologic exams

Memory trick: 'Sims on your side for the backside'

Patients should be seated with a supportive armrest or lying supine during venipuncture to minimize injury risk if they experience vasovagal syncope (fainting).

• Armrest prevents falls if patient faints
• Supine position is an alternative for high fall-risk patients
• Standing is avoided due to injury risk

Memory trick: 'Sit supported or lie flat, don't stand where you might fall flat'

Patient lies on the back with knees bent and feet flat on the exam table, used for abdominal exams and some pelvic/genital exams.

• Similar to lithotomy but without stirrups
• Feet flat on table, knees bent
• Used for abdominal palpation and catheterization

Memory trick: 'Dorsal recumbent = knees bent, feet flat, no stirrups needed'

Patient lies face down, often with arms at sides or above the head, used to examine the back, spine, or buttocks.

• Face down, flat on abdomen
• Used for back, spine, and some minor procedures
• Opposite of supine position

Memory trick: 'Prone to fall on your face' = face-down position for the back

To convert a patient's weight from pounds to kilograms, divide the weight in pounds by 2.2 (since 1 kg ≈ 2.2 lb).

• 1 kg = 2.2 lb
• Formula: kg = lb ÷ 2.2
• Accurate weight conversion is essential for weight-based dosing

Memory trick: Divide by 2.2 to shrink pounds down to kilograms.

Lithium or sodium heparin tubes (green-top) prevent clotting, allowing rapid plasma separation for time-sensitive chemistry testing.

• Heparin inhibits thrombin formation
• Used for stat electrolytes and blood gases
• No clot time needed before centrifugation

Memory trick: Green means go fast—heparin skips the clot wait.

The first drop of blood from a capillary puncture is wiped away before sample collection to prevent contamination from tissue fluid or antiseptic residue.

• First drop may contain interstitial fluid
• Wiping prevents diluted/inaccurate results
• Applies to glucose and other POC capillary tests

Memory trick: First drop's a dud—wipe it, then collect the good stuff.

A brief statement, ideally in the patient's own words, describing the primary reason for the office visit.

• Recorded in patient's own words when possible
• Often placed in quotation marks in the chart
• Distinct from the history of present illness

Memory trick: 'Chief in quotes, complaint devotes.'

A tourniquet should not remain on the arm longer than one minute to avoid hemoconcentration, which can skew laboratory results.

• Release tourniquet within 1 minute of application
• Prolonged use raises protein, cellular, and enzyme levels falsely
• If vein is hard to find, release and reapply after 2 minutes

Memory trick: 'One minute max, or the blood gets stacked' (hemoconcentration).

A chaperone (often the medical assistant) should be present during sensitive physical examinations such as pelvic, breast, or genital exams to protect both patient and provider and to provide reassurance.

• Required especially with gender difference between provider and patient
• Chaperone remains in the room throughout exam
• Provides legal protection and patient comfort

Memory trick: Stay in the room, protect them both

Calculating medication dose based on patient weight requires converting pounds to kilograms before multiplying by the mg/kg order.

• 1 kg = 2.2 lb
• Formula: (Weight in lb ÷ 2.2) x mg/kg ordered
• Always convert units before calculating final dose

Memory trick: 'Divide by 2.2 before you multiply'

A supine position with the head lower than the feet, used to treat shock and improve venous return to vital organs.

• Feet elevated above head level
• Used for shock, hypotension, and certain surgical procedures
• Contraindicated in patients with respiratory or increased intracranial pressure issues

Memory trick: 'Trendelenburg tips the trunk to save the shocked.'

Controlled substances with the lowest abuse potential, sometimes available without a prescription but requiring pharmacy purchaser logs.

• Examples: cough syrups with small amounts of codeine, some antidiarrheal agents
• Purchaser must show ID and be logged by pharmacist in states allowing OTC sale
• Still classified as controlled due to trace narcotic content

Memory trick: 'V is for Very low risk, sometimes OTC'

Sounds heard through a stethoscope during manual blood pressure measurement that indicate systolic and diastolic pressures.

• Phase I: first tapping sound = systolic
• Phase V: sounds disappear = diastolic
• Five phases total describe sound changes during cuff deflation

Memory trick: 'First sound starts systolic, silence signals diastolic.'

Standard EKG calibration is 10 mm = 1 mV, meaning each millimeter of deflection equals 0.1 mV of electrical voltage.

• Standard calibration: 10 mm = 1 mV
• Each mm = 0.1 mV
• Used to verify accurate machine calibration and voltage measurement

Memory trick: Ten millimeters, one millivolt—divide by ten for each mm.

The apical pulse is auscultated at the fifth intercostal space, midclavicular line, and should be counted for a full 60 seconds when irregular.

• Located at point of maximal impulse (PMI)
• Full minute count needed for irregular rhythms
• Used often in infants and cardiac patients

Memory trick: Apex needs a full sixty seconds

A non-additive or clotting tube drawn before a coagulation tube when using a butterfly set to eliminate air in the tubing.

• Butterfly tubing contains air that would underfill the first tube
• Discard tube prevents inaccurate blood-to-citrate ratio
• Discard tube can be another light blue or a non-additive tube, per facility policy

Memory trick: 'Butterfly needs a warm-up tube before the real one'

A class of antihypertensive drugs ending in '-pril' that block angiotensin-converting enzyme, reducing vasoconstriction and blood pressure.

• Examples: lisinopril, enalapril, captopril
• Common side effect: dry cough
• Used for hypertension and heart failure

Memory trick: 'Pril spills pressure down'

A point-of-care test for group A streptococcus requiring a swab of the tonsils and posterior pharynx, avoiding tongue and cheek contact to reduce contamination.

• Swab both tonsils and posterior pharyngeal wall
• Avoid touching tongue, cheeks, or uvula
• False negatives can occur with insufficient specimen contact

Memory trick: 'Aim for the tonsils, skip the tongue.'

A class of medications that block calcium channels in the heart and blood vessels, leading to relaxation of vascular smooth muscle, reduced peripheral vascular resistance, and decreased myocardial contractility and heart rate.

• Used to treat hypertension, angina, and some arrhythmias.
• Common examples: amlodipine, diltiazem, verapamil.
• End in -dipine, -zem, or -amil.

Memory trick: Blood Pressure: A-B-C-D

Intradermal injections are administered at a 10-15 degree angle to place medication into the dermis.

• Used for allergy tests and TB skin tests.
• Creates a small wheal or blister.
• Shallowest injection depth.

Memory trick: ID is 'Low' at 15°, SubQ 'Mid' at 45°, IM 'High' at 90°.

Beta-blockers, especially non-selective ones, can cause bronchoconstriction by blocking beta-2 adrenergic receptors in the lungs, leading to exacerbation of asthma symptoms. Even cardioselective beta-1 blockers can have this effect at higher doses or in sensitive patients.

• Beta-blockers block beta-adrenergic receptors.
• Beta-2 receptors in lungs cause bronchodilation when stimulated.
• Blocking beta-2 receptors can lead to bronchoconstriction.
• Use with extreme caution, if at all, in patients with asthma/COPD.

Memory trick: Beta-Blockers Block Breathing for Bronchial Patients.

The seven rights ensure safe medication administration: patient, medication, dose, route, time, documentation, and reason.

• Documentation is the final critical step.
• Helps prevent errors and ensures continuity of care.
• A systematic approach to medication safety.

Memory trick: Patients Meds Dose Route Time, Doc Reason Refuse.

Schedule IV controlled substances have a low potential for abuse and a low risk of physical or psychological dependence. They are commonly prescribed for anxiety, insomnia, and certain seizure disorders.

• Examples: diazepam, lorazepam, alprazolam, zolpidem.
• Prescriptions can often be refilled up to 5 times within 6 months.
• Less stringent record-keeping than Schedule II or III.

Memory trick: 1 is High, 5 is Low, IV is In-Between.

Subcutaneous injection sites are areas of the body with sufficient subcutaneous fat to allow for medication absorption into the adipose tissue, typically including the outer aspects of the upper arms, the abdomen, and the anterior/lateral thighs.

• Sites include: upper outer arms, abdomen (at least 1 inch from navel), anterior/lateral thighs.
• Rotate sites to prevent lipodystrophy.
• Avoid areas with scars, bruises, or inflammation.

Memory trick: SC = Skin's Cushion Sites

A standardized coding system used to report supplies, durable medical equipment (DME), ambulance services, and certain drugs/biologicals not included in CPT codes.

• Alphanumeric format: one letter followed by four numbers (e.g., E-codes for DME)

• Different from CPT (procedures) and ICD-10-CM (diagnoses)

Memory trick: HCPCS Level II = 'Hardware, Crutches, Prosthetics, Chairs, Supplies'

Diuretics, like furosemide, are generally taken in the morning to prevent nocturia and sleep disturbance.

• Increases urine output.
• Prevents dehydration if taken correctly.
• Commonly used for hypertension and edema.

Memory trick: Diuretics: 'Morning' means more peaceful nights.

Unit conversion in dosage calculation involves converting between different units of measurement (e.g., mg to mcg, grams to milligrams) to ensure consistency before performing the final calculation.

• 1 mg = 1000 mcg.
• Always convert to the same unit before dividing.
• Accuracy in conversion is critical for patient safety.

Memory trick: Convert First, Then Divide!

Needle gauge refers to the diameter of the needle. For intramuscular injections, the gauge is selected based on the patient's size, medication viscosity, and injection site.

• Higher gauge number means a thinner needle.
• Common IM gauges are 20-25 gauge.
• Thinner needles (higher gauge) cause less pain.

Memory trick: Gauge, Go, Get Good Muscle

A CPT modifier appended to an E/M code to indicate a significant, separately identifiable evaluation and management service was performed by the same provider on the same day as another procedure or service.

• Allows separate billing of E/M when a distinct problem is addressed
• Commonly used when a minor procedure and an unrelated problem are both addressed in one visit
• Different from modifier -24 (postoperative unrelated E/M) and -59 (distinct procedural service)

Memory trick: 25 = 'two-for-one' visit, separate issue billed separately

An ICD-10-CM coding element required for injury, poisoning, and certain other codes that specifies the episode of care: A (initial), D (subsequent), or S (sequela).

• A = active treatment (initial encounter)
• D = routine healing/recovery phase (subsequent)
• S = sequela, a late effect after the acute phase resolves

Memory trick: A is for Active treatment, D is for Down the road, S is for Sequela

A coordination-of-benefits guideline stating that when a dependent child is covered by two parents' group health plans, the plan of the parent whose birthday occurs earlier in the calendar year is primary.

• Uses month/day only, not birth year
• Applies to dependent children covered under both parents' plans
• Prevents duplicate full payment by both insurers

Memory trick: Earlier birthday = earlier payer

To calculate the number of tablets to administer, divide the ordered dose by the available dose per tablet.

• Formula: (Ordered Dose / Available Dose per Tablet) = Number of Tablets.
• Always double-check calculations.
• Essential for accurate medication administration.

Memory trick: Order Divided by Available tells you How Many.

Omeprazole is a proton pump inhibitor that reduces stomach acid production, primarily affecting the gastrointestinal system.

• Used to treat GERD, ulcers, and heartburn.
• Works by blocking the enzyme system (H+/K+ ATPase).
• Taken orally, usually once daily before a meal.

Memory trick: PPIs Protect the Gut, Stop the Burn.

Proton pump inhibitors (PPIs) are medications that irreversibly block the hydrogen-potassium ATPase enzyme system (the proton pump) in gastric parietal cells, thereby reducing gastric acid secretion.

• Used to treat acid-related disorders.
• Examples include omeprazole, lansoprazole, pantoprazole.
• Common indications: GERD, peptic ulcer disease, H. pylori eradication.

Memory trick: PPIs Protect the Stomach from Pumping too much acid.

An appointment scheduling method in which multiple patients are scheduled for the same broad time block (e.g., the beginning of each hour) and seen in the order they arrive.

• Helps absorb no-shows and variable exam lengths
• Patients within the block are seen first-come, first-served
• Contrasts with stream scheduling, which gives individual fixed times

Memory trick: Wave = group of patients riding in on the hour

SSRIs are a class of antidepressants that primarily block the reabsorption (reuptake) of serotonin in the brain, thereby increasing the availability of serotonin to improve mood.

• First-line treatment for depression, anxiety disorders.
• Examples: fluoxetine, sertraline, paroxetine, escitalopram.
• Generally fewer side effects than TCAs or MAOIs.

Memory trick: SSRIs Make Serotonin Soar!

Antiplatelet medications like clopidogrel reduce the ability of platelets to stick together, thereby preventing clot formation. The primary adverse effect is an increased risk of bleeding.

• Report signs of bleeding (bruising, blood in stool/urine).
• Do not stop medication without consulting a provider.
• Avoid NSAIDs unless approved by provider.

Memory trick: Plavix Prevents Platelets Puncturing

The appropriate needle length for intramuscular injections at the ventrogluteal site in average-sized adults is typically 1 to 1 1/2 inches.

• Ensures medication reaches muscle tissue.
• Prevents medication from being deposited into subcutaneous tissue.
• Length varies based on patient size and injection site.

Memory trick: Longer needles make muscles happy.

A statement sent by a health insurance company to the insured explaining what medical services were billed, what was paid, and what the patient owes.

• Sent to the patient/policyholder, not the provider
• Shows billed charge, allowed amount, insurance payment, patient balance
• Not a bill itself — it's a summary of claim processing

Memory trick: EOB explains, RA remits to the office

When a patient has difficulty swallowing (dysphagia), alternative medication forms or administration methods must be considered, but always with caution and physician approval to ensure safety and efficacy.

• Never crush or alter medications without verification.
• Consult pharmacist or drug reference for crushability.
• Liquid forms, chewables, or dissolvable tablets are alternatives.
• Physician's order is always required for changes.

Memory trick: Difficulty Down? Doctor's Decision!

Intradermal injections are given into the dermal layer of the skin, just below the epidermis. The ventral forearm is the most common site due to its thin skin and easy visibility for reaction assessment.

• Common for allergy tests and PPD (TB) tests.
• Small volume (0.01-0.1 mL) is injected.
• Forms a wheal or bleb on the skin surface.

Memory trick: Many Routes, Many Spots

Needle gauge refers to the diameter of the needle lumen; a lower gauge number indicates a larger needle diameter. For viscous intramuscular injections, a larger diameter needle (smaller gauge number, typically 21-22 gauge) is preferred to ensure smooth administration.

• Gauge is inversely proportional to needle diameter.
• Viscous medications require larger diameter needles.
• Common IM gauges are 20-25; 21-22 are often used for thicker solutions.

Memory trick: Gauge Goes Bigger, Hole Gets Smaller

The vastus lateralis muscle is the preferred site for intramuscular injections in infants and toddlers (0-2 years).

• Large, well-developed muscle.
• Located in the anterolateral thigh.
• Low risk of nerve or blood vessel damage.

Memory trick: Infants need their 'V'accine in the 'V'astus.

Adherence to antibiotic regimens, particularly completing the full prescribed course, is vital for effective treatment, preventing recurrence of infection, and mitigating the development of antibiotic resistance.

• Do not stop early, even if feeling better.
• Incomplete courses promote drug-resistant bacteria.
• Take at prescribed intervals to maintain therapeutic levels.

Memory trick: Antibiotics: Always Finish

To determine the volume of medication to administer when the order is in milligrams and the concentration is in milligrams per milliliter, divide the desired dose by the available concentration.

• Formula: Desired / Have = Volume.
• Ensure units match (mg to mg).
• Ignore reconstitution volume if concentration is already given.

Memory trick: Don't Hesitate, Calculate!

When calculating dosages, always convert units to be consistent before performing the division.

• 1 mg = 1000 mcg.
• Unit conversion is a common source of error.
• Double-check conversions and calculations.

Memory trick: Convert First, Then Divide, for the Right Amount to provide.

For adult deltoid intramuscular injections, a 1-inch needle length is generally appropriate to ensure muscle penetration.

• Needle length depends on patient size and injection site.
• Must reach the muscle layer for IM injections.
• Too short, and medication may go into subcutaneous tissue.

Memory trick: Deltoid IM: 'One' inch is the one to pick.

A fraudulent billing practice of separately reporting the individual components of a procedure or panel that should be billed under one comprehensive CPT code, to increase reimbursement.

• Considered fraudulent and audited by payers (e.g., via NCCI edits)
• Contrasts with upcoding (billing a higher-level service than performed)
• National Correct Coding Initiative (NCCI) edits help detect unbundling

Memory trick: Unbundling = breaking one bundle into many pieces for more money

Statins are a class of lipid-lowering medications that inhibit HMG-CoA reductase, an enzyme involved in cholesterol synthesis. They are primarily used to treat hyperlipidemia.

• Lower LDL cholesterol effectively.
• Reduce risk of cardiovascular events (heart attack, stroke).
• Common examples: atorvastatin, simvastatin, rosuvastatin.

Memory trick: Statins Stop Saturated Stuff

A legal order compelling a person or entity to produce specific documents or records, such as medical records, for use in a legal proceeding.

• Requires production of documents, unlike subpoena ad testificandum (testimony)
• Office should verify validity and consult legal counsel before responding
• Copies, not originals, are typically provided; originals remain in the practice's possession

Memory trick: Duces Tecum = 'bring the documents,' but verify before you deliver

CPT codes are divided into three categories: Category I (standard procedures/services), Category II (performance measurement, optional, no reimbursement), and Category III (emerging technology, temporary).

• Category I = 5-digit numeric codes for reimbursable services
• Category II = alphanumeric codes ending in F, used for quality tracking
• Category III = alphanumeric codes ending in T, temporary for new technology

Memory trick: I bills, II tracks quality, III is temporary tech

To alleviate nausea/vomiting from antibiotics, advise taking with food or a full glass of water, unless contraindicated.

• GI upset is a common antibiotic side effect.
• Food/water can buffer the stomach.
• Never discontinue or alter dosage without provider's order.

Memory trick: Antibiotics: 'Eat' with them, 'Drink' with them to feel better, don't 'Quit' or 'Double'.

Metformin is an oral antidiabetic medication primarily used to treat Type 2 Diabetes Mellitus.

• Belongs to the biguanide class.
• Reduces hepatic glucose production.
• Improves insulin sensitivity.

Memory trick: Metformin for 'M'aintaining 'M'y sugar levels.

Medication instructions regarding food intake (with or without food) are specific to each drug and must be followed as prescribed or labeled.

• Food can affect drug absorption, metabolism, and side effects.
• Some drugs need food to prevent stomach upset or improve absorption.
• Some drugs are absorbed better on an empty stomach.
• Always refer to specific drug instructions.

Memory trick: Specific Label, Safe Patient.

The angle of insertion for a subcutaneous injection is typically 45 degrees to ensure the medication is delivered into the fatty tissue layer beneath the skin.

• Angle may be 90 degrees for obese patients or with shorter needles.
• Common sites: abdomen, outer upper arm, anterior thigh.
• Pinch skin to create a fat fold for insertion.

Memory trick: I.D. 15, S.Q. 45, I.M. 90

A written notice given to a Medicare beneficiary before a service is provided, informing them that Medicare may not cover the service and that they may be financially responsible if it is denied.

• Must be given before the service, not after
• Used when medical necessity is in question under Medicare guidelines
• Allows the patient to choose to receive the service and accept potential payment liability

Memory trick: ABN = 'Are you willing to pay Before we begin, if Not covered?'

St. John's Wort is a potent enzyme inducer that can reduce the effectiveness of many medications, notably oral contraceptives.

• Induces CYP3A4 enzymes.
• Decreases blood levels of co-administered drugs.
• Other affected drugs include anticoagulants, antiretrovirals, and digoxin.

Memory trick: St. John's Wort: 'OC' no baby, 'OC' no effect.

Antibiotic photosensitivity is an adverse reaction where certain antibiotics increase the skin's sensitivity to ultraviolet (UV) radiation, leading to exaggerated sunburns, rashes, or other phototoxic/photoallergic reactions upon sun exposure.

• Common culprits: tetracyclines (doxycycline), fluoroquinolones (ciprofloxacin), sulfonamides (sulfamethoxazole-trimethoprim).
• Advise patients to use broad-spectrum sunscreen (SPF 30+), wear protective clothing, and seek shade.
• Reactions can occur even with brief sun exposure.

Memory trick: Photosensitivity: Sun's Out, Be Safe!
