When a small sample of tissue is taken from the body and sent to a clinical laboratory to be examined or studied, it is called a biopsy. Biopsies are performed to diagnose diseases, such as cancer, by analyzing tissue samples under a microscope. This procedure provides critical information about the presence and extent of diseases.

The muscle walls of the heart are called the myocardium. This is the thick, muscular layer of the heart responsible for contracting and pumping blood throughout the body. The myocardium is composed of specialized cardiac muscle cells that enable the heart to function as an efficient pump. It is distinct from the endocardium (inner lining) and the epicardium (outer layer) of the heart.

-orrhaphy: Refers to surgical suturing.

-ocentesis: Refers to surgical puncture to remove fluid.

When using a microscope, the total magnification is calculated by multiplying the magnification power of the ocular lens (eyepiece) by the magnification power of the objective lens. In this case, a 10X ocular lens combined with a 40X objective lens results in a total magnification of400X(10X * 40X = 400X).Reference:Nationally Registered Certified Medical Assistant study materials on microscopy.

Gram stainingis a laboratory technique used to classify bacteria based on the characteristics of their cell walls. This method differentiates bacteria intogram-positive(which retain the crystal violet stain and appear purple) andgram-negative(which do not retain the violet stain and appear red after counterstaining). This classification helps in guiding the appropriate antibiotic treatment and understanding the bacterial structure. It does not determine the species of the organism directly, nor is it used to diagnose cervical cancer.

A tray for a pelvic examination normally includes a vaginal speculum and lubricant. The speculum is a medical tool used to open the vaginal walls for visual inspection and access to the cervix during the examination. Lubricant is applied to the speculum to ease insertion and increase patient comfort. Other instruments that may be included depending on the specific examination or procedure are gloves, tenaculum, and hemostat forceps. Proper preparation of the examination tray ensures that the healthcare provider has all necessary tools readily available, facilitating a smooth and efficient examination process.

The abbreviation forimmediatelyisSTAT. This term is used in medical contexts to indicate that an action is to be taken immediately, derived from the Latin word "statim."

A patient in thesupine positionis lying flat on their back with their palms and face up. This position is commonly used during surgeries and medical examinations as it provides easy access to the patient's anterior body, including the chest and abdomen.

Lying face down: This is known as the prone position.

Lying on the left side with the right leg flexed: This is often referred to as the left lateral or left Sims' position.

Lying on the right side with the left leg flexed: This is the right lateral or right Sims' position.
