When insulin is higher than the body's need and blood glucose falls, the result is hypoglycemia. This is the current, precise term for low blood sugar. Insulin shock is an older way some clinicians described severe hypoglycemia with symptoms like confusion or unconsciousness, but the preferred term today is hypoglycemia. The other options describe different problems: hyperglycemia means high blood glucose, and diabetic ketoacidosis is a serious diabetes complication involving high glucose and ketone buildup. Knowing this helps you recognize and respond to low blood sugar appropriately—check the level, provide a fast-acting carbohydrate if the person can swallow, and seek emergency help or administer glucagon if the person is unconscious or unable to safely take fluids.

The main idea here is how to correctly operate a portable fire extinguisher using a simple, repeatable sequence. PASS helps you do that safely and effectively: Pull the pin to break the tamper seal, Aim the nozzle at the base of the fire, Squeeze the handle to release the extinguishing agent, and Sweep the nozzle from side to side at the base of the flames. Doing it in this order ensures you disable the fuel source at the bottom of the fire and maintain control as you work across the fire. This matches the option describing those four actions. Other phrases in the distractor options refer to alarms, evacuation, or general safety steps, not the precise actions used to deploy a fire extinguisher.

Abnormally high blood pressure is described by the term hypertension. Hypertension means that arterial pressure remains elevated beyond normal on repeated measurements, signaling a chronic condition that raises risks for heart disease, stroke, and kidney problems. This term is different from hypotension, which is low blood pressure; from systole, which is the heart’s contraction phase during the heartbeat; and from Clean Catch Urine, which is simply a method for collecting a urine sample. Recognizing hypertension helps you understand why regular blood pressure checks and potential lifestyle changes or medications are important to reduce cardiovascular risk.

The main concept here is personal protective equipment. The gloves, gowns, masks, and eye protection are the protective barriers used by healthcare workers to prevent exposure to infectious agents during patient care. Each item blocks a specific route of transmission: gloves guard hands, gowns protect skin and clothing, masks filter or block respiratory droplets, and eye protection shields the eyes. Together, they form PPE, which is applied as part of standard precautions and adapted to situations requiring transmission-based precautions. The other terms refer to broader practices or unrelated equipment, not the protective gear itself.
