80 multiple-choice questions and 32 flashcards on Clinical, about 50% of the CMA bank. Every one carries a written rationale.
Clinical is one of 3 chapters in CoStudy's CMA (AAMA Certified Medical Assistant) bank, and it holds 80 of the bank's 160 multiple-choice questions — roughly 50% of the total. That proportion is not arbitrary: chapters follow the certifying body's published exam outline, and the number of questions in each is set by that domain's published weight, so the share of your practice time this chapter takes matches the share of the real exam it accounts for.
Studying by chapter is worth doing once you have a diagnostic score. A single overall percentage tells you whether you are close; it does not tell you which domain is dragging. Working a weak chapter in isolation, and re-testing it in isolation, is the fastest way to move a score that has stalled — and it is why the mock exams in CoStudy report by domain rather than as one number.
8 questions drawn from this chapter, with the full rationale shown — the controlling principle behind the right answer, and why each wrong option tempts and fails.
Sterilization monitoring with biological indicators (spore tests) should be performed:
Answer: B — At least weekly + with every implant load
A) Above standard frequency. B) AAMI/CDC: at minimum once weekly; with each load containing implantables; also after major repairs. C) Quarterly is too infrequent. D) Service is one trigger, not the only one.
Two-patient-identifier requirement means:
Answer: B — Two unique identifiers per patient (e.g., name + DOB)
A/C/D) Wrong. B) Correct — name + DOB is canonical.
A normal sinus rhythm on a 12-lead EKG most reliably includes:
Answer: D — Upright P waves in lead II, a P before every QRS, regular R-R intervals, rate 60-100
A) Atrial fibrillation pattern. D) Definition of NSR. C) Atrial flutter. B) Ventricular rhythm.
You should perform hand hygiene with soap + water (NOT alcohol rub) when:
Answer: A — Hands visibly soiled OR after C. difficile contact
B/C/D) Wrong. A) Correct — alcohol doesn't kill C. diff spores.
A prescription for a controlled substance with refills authorized over a 6-month period is most consistent with:
Answer: D — A Schedule V drug, which has the most permissive federal refill rules
A) Schedule I has no accepted medical use + cannot be prescribed at all. B) Schedule II (morphine, oxycodone, Adderall) requires a new prescription for each fill — no refills. C) Schedule III allows up to 5 refills within 6 months. D) Schedule V (e.g., low-dose codeine cough syrups) has the most permissive federal refill restrictions, making longer-duration scripts most consistent with this tier.
An apical pulse should be:
Answer: D — Counted for a full 60 seconds, especially in pediatric or irregular rhythms
A) 15-second counts miss subtle irregularities. D) Apical pulses, particularly in infants + with arrhythmias, are auscultated at the 5th ICS midclavicular line for a full minute. C) Apical = at the apex of the heart, not the wrist. B) Apical assessment is not a fallback for carotid technique.
A DASH (Dietary Approaches to Stop Hypertension) eating plan emphasizes:
Answer: D — Vegetables, fruits, whole grains, low-fat dairy, lean protein; reduced sodium
A) Opposite. D) DASH guidelines + sodium reduction (≤2,300 mg/day, ideally 1,500 mg). C) Keto is a separate regimen. B) DASH includes carbohydrates from whole grains, fruits, vegetables.
Z-track method is used for:
Answer: D — Irritating medications + iron — to prevent leakage into subcutaneous tissue
A) SubQ. D) Correct — pull skin laterally before injection. B/C) Wrong.

Standard precautions?
Treat all body fluids as potentially infectious. PPE (gloves, gown, mask, eyewear), hand hygiene, sharps safety, proper waste disposal.
Anaphylaxis recognition + response?
Sudden swelling, hives, wheezing, hypotension after exposure. CALL 911 / Code. Epinephrine 0.3 mg IM (adult auto-injector). Lay patient flat (or sit if breathing better). Repeat epi q5-15 min if needed.
These are a sample. The full Clinical chapter runs 112 items with per-chapter progress tracking, on the web and in the iOS app.
