Final answer:
Health care personnel conducting a pressure test, such as blood pressure measurement with a sphygmomanometer, must ensure safety and accuracy by having a maintained stock of laboratory supplies, verifying procedures, and using catheters for invasive internal pressure measurements during surgeries or intensive care.
Step-by-step explanation:
Personnel conducting a pressure test should take several precautions. The pressures in various parts of the body provide valuable medical indicators, but measurements are typically invasive. During procedures such as surgery or intensive care monitoring, qualified health care workers use catheters to measure internal pressures and transmit these to external devices. A typical device used for non-invasive pressure measurement is a sphygmomanometer, which includes a valved rubber bulb to inflate the cuff and a diaphragm gauge to measure blood pressure. It is crucial that health care providers conducting pressure tests or any lab-related activities maintain a safe environment by ensuring a maintained stock of laboratory supplies, verifying procedure names, and addressing any equipment issues.
