Clinical Procedures and Patient Care
Preparing and Assisting
Clinical procedures blend preparation, safety, and communication. Before any procedure, identify the patient with two identifiers, verify the order, explain the procedure, obtain consent when required, and ensure privacy. Know standard vital signs and how to measure them correctly: temperature, pulse, respiration, blood pressure, and oxygen saturation, plus pain as the “fifth vital sign.”
Concepts to Master
- Normal adult ranges: oral temperature about 98.6°F (37°C), pulse 60–100 beats/min, respirations 12–20/min, blood pressure under 120/80 mmHg, SpO2 95–100% on room air.
- Positions: supine, prone, Fowler (semi- to high-Fowler for breathing), Sims (left side, for enemas), lithotomy (pelvic exam), Trendelenburg (head down), knee-chest.
- Exam prep: draping, instrument setup, chaperone for sensitive exams, labeling specimens at the bedside.
- Scope of practice: medical assistants prepare and assist but do not diagnose, prescribe, or interpret results.
- Documentation: objective findings, patient statements, time, and who performed the procedure.
Traps
Questions test whether you know when to stop and refer - for example, an abnormal vital sign, a patient refusing a procedure, or a request outside your scope. A common trap is cuff size: a cuff that is too small falsely raises blood pressure, while one that is too large falsely lowers it. Do not confuse Fowler and Trendelenburg, and remember that consent is the provider’s responsibility to obtain, though you may witness it.
Worked Example
A patient’s blood pressure reads 158/96 mmHg. You recheck after five minutes of rest with the arm supported at heart level and an appropriately sized cuff, then report the value to the provider and document it. Rule of thumb: measure, recheck if abnormal, report, and document - never reassure or diagnose on your own.
