Clinical Procedures
Clinical procedures questions test whether you can perform common medical-assistant tasks safely and in the right sequence. Know vital-sign technique: correct cuff size and arm position for blood pressure, proper thermometer route and dwell time, pulse and respiration counting, and pulse oximetry limitations. Understand aseptic technique: medical asepsis versus surgical asepsis, hand hygiene, PPE order, sterile-field rules, and the difference between disinfection and sterilization. Autoclave monitoring uses physical, chemical, and biological indicators; the biological spore test is the most reliable. For injections, know sites, needle gauge and length, angle, and safe sharps disposal. Venipuncture questions often test order of draw, tourniquet time, site selection, and labeling at the bedside. Specimen handling depends on type: urine, stool, sputum, blood, or throat swab. EKG prep includes skin preparation, lead placement, and artifact avoidance; spirometry requires coaching and awareness of contraindications.
Traps include confusing sterilization with disinfection, choosing a route or needle by habit rather than patient size, forgetting to identify the patient with two identifiers, drawing blood before labeling tubes, leaving a tourniquet on too long, or answering 'call the provider' before stopping an unsafe procedure. Read for the words first, immediately, and never.
Worked rule: A 6-year-old needs an intramuscular injection. The vastus lateralis is generally preferred when muscle mass is adequate; select needle length by age, weight, and site, not convenience. If a patient becomes dizzy during venipuncture, stop the procedure, protect the patient, and assess.
