Another name for myocardial infarction is heart attack. A myocardial infarction occurs when blood flow to a part of the heart is blocked for a long enough time that part of the heart muscle is damaged or dies. It is typically caused by the blockage of a coronary artery due to plaque buildup.

A simple sugar to which all forms of carbohydrates are ultimately converted isglucose. Glucose is the primary source of energy for the body's cells and is transported in the blood to be used immediately or stored for later use. Carbohydrates from foods are broken down into glucose during digestion.

A mild hypnotic drug that is relaxing but doesn't necessarily produce sleep is called a sedative. Sedatives are used to calm patients, reduce anxiety, and induce relaxation. They are commonly used in medical settings to prepare patients for procedures or to alleviate stress and anxiety.

An agent which excites and promotes functional activity is called astimulant. Stimulants are substances that increase the activity of the central nervous system and the body, leading to increased alertness, attention, and energy. Examples include caffeine, nicotine, and certain medications used to treat ADHD.Reference:Nationally Registered Certified Medical Assistant study materials, pharmacology references.

A Z-tract injection is a technique used to administer medication intramuscularly to minimize leakage and irritation of the medication in the subcutaneous tissue. The Z-tract method involves pulling the skin and subcutaneous tissue to one side before inserting the needle into the muscle, injecting the medication, and then releasing the tissue after withdrawing the needle. This "zig-zag" path prevents the medication from leaking back along the needle track. The gluteal muscle, particularly the ventrogluteal or dorsogluteal sites, is commonly used for such injections due to its large muscle mass.

Pathologyis the study of disease, including its causes, processes, development, and consequences. Pathologists examine tissues, organs, bodily fluids, and autopsies to understand disease mechanisms and assist in diagnosis and treatment. The field encompasses several branches, such as clinical pathology, anatomical pathology, and forensic pathology.

Study of paths: Not relevant in medical terminology.

Process of disease: Part of pathology but not a complete definition.

Remission of disease: Refers to the reduction or disappearance of symptoms, not the study.

During galvanic electrical stimulation, it is crucial that the patient is attended at all times. This procedure involves the use of direct current (DC) to stimulate muscle contraction and requires continuous monitoring to ensure the patient's safety and to adjust the settings if needed. Unattended galvanic stimulation can pose risks such as burns or other injuries, hence constant supervision is essential.

The purpose of applying paste or jelly when running anEKG (Electrocardiogram)is toreduce skin resistance. This conductive gel ensures better conductivity between the skin and the electrodes, resulting in a clearer and more accurate recording of the heart's electrical activity. Without the gel, poor contact can lead to high resistance and artifacts in the EKG trace.

An agent given to counteract an unwanted effect of a drug is called an antidote. Antidotes are used to neutralize or mitigate the effects of poisons or overdoses of medications, ensuring patient safety and recovery from toxic exposures.

The universal donor blood type isO negative (O-). This means that individuals with this blood type can donate blood to recipients of any other blood type. This is due to the absence of A and B antigens on the red blood cells and the lack of Rh antigen, which prevents the immune system of the recipient from recognizing the donor blood as foreign. The concept of universal donor is fundamental in emergency situations when there's no time to cross-match blood types.
