Iom Quiz #2 Terminology & Electrode Placement V-VI & P18-41

The correct answer is "The central nervous system." The term CNS is commonly used in the medical field to refer to the central nervous system, which includes the brain and spinal cord. It is responsible for coordinating and controlling the body's activities and functions. The other options mentioned in the question do not accurately represent the meaning of CNS.

The CPA is a space located between the cerebellum and the pons where tumors may grow. When removing tumors in the CPA region, it is important to monitor the VIII nerve, also known as the vestibulocochlear nerve, which is responsible for hearing and balance. Surgical approaches to the CPA can pose a risk to auditory function, highlighting the importance of careful monitoring and preservation of the nerve. Therefore, all of the statements provided are true about the CPA.

The given statement is true. Hct is indeed an abbreviation for hematocrit. Hematocrit is a medical term that refers to the volume percentage of red blood cells in the blood. Hct is commonly used as a shorthand abbreviation for hematocrit in medical documentation and discussions.

The correct answer is anterior cervical instrumentation and fusion.

The correct answer is ISI. The interstimulus interval (ISI) refers to the time between the presentation of two consecutive stimuli. It is commonly used in experiments to study perception and cognition. The other options (ISS, INTi, Int.SI) do not represent the correct abbreviation for interstimulus interval.

DLIF stands for Direct Lateral Interbody Fusion. This surgical procedure involves accessing the spine through a lateral approach, meaning that the surgeon approaches the spine from the side. The interbody fusion part refers to the fusion of two adjacent vertebrae using a bone graft or implant. This procedure is commonly used to treat conditions such as degenerative disc disease, spinal stenosis, and spondylolisthesis.

The correct answer is BAEP: brainstem auditory-evoked potential/response

MAP stands for Mean Arterial Pressure. It is a measure of the average blood pressure in the arteries during one cardiac cycle. It is calculated by taking into account both the systolic and diastolic blood pressure values. MAP is an important indicator of perfusion pressure in the organs and tissues of the body. It is often used in medical settings to assess a patient's cardiovascular health and to guide treatment decisions.

The peroneal nerve is stimulated 2cm distal to the fibular head. The peroneal nerve is a branch of the sciatic nerve and innervates the muscles of the lower leg and foot. It is responsible for dorsiflexion of the foot and extension of the toes. Stimulation of the peroneal nerve at this specific location can help diagnose and treat conditions such as peroneal neuropathy or foot drop.

Computerized axial tomography (CAT) scan is a medical imaging technique that uses X-rays and computer processing to create detailed cross-sectional images of the body. The term "computerized axial tomography" accurately describes the process of using computers to generate images of the body by taking multiple X-ray images from different angles.

PLIF stands for posterior lumbar instrumentation and fusion.

The greater and lesser occipital nerves ascend the skull one inch lateral to the midline of the occiput.

The electrode is placed over the brachial plexus on the ipsilateral side to record Erb's point. This is the correct placement for recording Erb's point, which is a specific location on the brachial plexus where the upper trunk and the posterior division of the lower trunk merge.

The explanation for the given correct answer is that to acquire subcortical data, it is necessary to insert subdermal recording needles at the interspinous space, which is known as the root entry zone. This implies that the statement is true, as it accurately describes the correct method for acquiring subcortical data.

ET stands for End Tidal. End tidal refers to the measurement of the concentration of a gas, typically carbon dioxide, at the end of each exhaled breath. This measurement is used in medical settings to monitor the patient's respiratory status and the effectiveness of ventilation.

The correct placement for the sensory recording electrode for CPz is 2 cm posterior and 4 cm lateral to Cz.

Six electrodes are used for recording, two are used for stimulating, and one is used as a ground.

FI stands for "Fraction inspired" which refers to the fraction or percentage of inspired oxygen in the air. This term is commonly used in medical settings to indicate the concentration of oxygen being delivered to a patient. It is important to monitor and adjust the fraction inspired based on the patient's needs to ensure proper oxygenation.
