Amt Practice Exam

When an HMO hires physicians and pays them a salary to provide medical services, the HMO model being implemented is the Staff model. In this model, the physicians are directly employed by the HMO and receive a salary, rather than being independent contractors or receiving payment based on a fee-for-service arrangement. This allows the HMO to have more control over the physicians' practice patterns and ensures that they are focused on providing care within the HMO's guidelines and objectives.

The right lung is divided into three sections, known as lobes. These lobes are the superior, middle, and inferior lobes. Each lobe has its own separate blood supply and is further divided into smaller segments. The division of the lung into lobes allows for efficient ventilation and distribution of air throughout the lung.

Defamation is not one of the four elements of negligence. The four elements that patients must present evidence of before negligence can be proven are duty, direct cause, damages, and breach of duty. Defamation refers to making false statements that harm someone's reputation, but it is not directly related to negligence.

Arrector pili is an example of smooth muscle. Smooth muscles are involuntary muscles found in various organs and structures of the body. Arrector pili muscles are small muscles attached to hair follicles and are responsible for causing hair to stand up, creating "goosebumps" on the skin. They are composed of smooth muscle tissue, which is non-striated and under involuntary control. Triceps, biceps, and pectoralis are examples of skeletal muscles, which are striated and under voluntary control.

The gray stopper tube contains the anticoagulant potassium oxalate or sodium fluoride and is used for blood glucose determination. This tube is specifically designed to prevent the blood from clotting and contains substances that preserve the glucose levels in the blood. The use of anticoagulants in this tube ensures that the blood sample remains stable and accurate for glucose testing.

Peristaltic waves occur in the esophagus. These waves are rhythmic contractions of the smooth muscles in the esophagus that help to propel food from the mouth to the stomach. The muscles contract in a coordinated wave-like fashion, pushing the food downward through the esophagus. This process is essential for the movement of food through the digestive system and allows for efficient digestion and absorption of nutrients.

Grey matter is the correct answer because it is the nervous tissue of the brain and spinal cord that is composed of cell bodies and dendrites of nerve cells. Grey matter is responsible for processing information in the central nervous system and plays a crucial role in various cognitive functions such as memory, attention, and perception.

The renal pelvis is the correct answer because it is the cavity within the kidney that collects urine. It is a funnel-shaped structure that connects the kidney to the ureter, which then transports the urine to the urinary bladder. The renal pelvis serves as a reservoir for urine before it is eliminated from the body. Bowman's capsule, on the other hand, is a part of the nephron in the kidney that filters blood to form urine.

HIPAA (Health Insurance Portability and Accountability Act) requires covered entities to submit Medicare claims through electronic data exchange. This means that healthcare providers and other covered entities must use electronic means, such as electronic claims submission systems or clearinghouses, to transmit Medicare claims information securely and efficiently. This requirement aims to ensure the privacy and security of patient health information while streamlining the claims process for faster and more accurate reimbursement.

The metric prefix "hecto" represents the amount of one hundred. It is used to denote a multiple of 100 in the metric system.

Systolic pressure occurs during ventricular contraction. This is when the heart's ventricles contract and pump blood out of the heart and into the arteries. The contraction of the ventricles causes the highest pressure in the arteries, which is known as systolic pressure. This is the first number recorded when measuring blood pressure, representing the pressure when the heart is actively pumping blood.

The given combination of mineral to sources is incorrect for Iron. Nuts, whole grains, and veggies are good sources of iron, but coffee, tea, cocoa, and egg yolks are not. These foods can actually inhibit the absorption of iron in the body. Therefore, it is important to avoid consuming them with iron-rich foods to ensure proper absorption.

Medicare Part B covers prescription medical equipment. This refers to durable medical equipment (DME) that is prescribed by a doctor for use at home, such as wheelchairs, walkers, oxygen equipment, and hospital beds. Medicare Part B helps to cover the cost of these necessary medical devices to assist patients in managing their health conditions and improving their quality of life. It does not cover prescription drugs, routine eye examinations, or elective cosmetic surgery.

Light sensitive

The explanation for the given correct answer is that educating female patients on signs and symptoms of myocardial infarction includes all of the listed options except for the feeling of lightness or feeling famished in the mediastinum. The other options, such as back pain or aching and throbbing in the biceps or forearms, shortness of breath, and dizziness (vertigo) - unexplained lightheadedness or syncopal episodes, are all symptoms that can be associated with a myocardial infarction. However, feeling of lightness or feeling famished in the mediastinum is not a commonly reported symptom of a heart attack.

Sodium hypochlorite is recommended by OSHA for decontaminating blood spills. Sodium hypochlorite, commonly known as bleach, is a strong disinfectant that can effectively kill pathogens, including bloodborne pathogens. It is a commonly used chemical for sanitizing and disinfecting surfaces in healthcare settings. Its strong oxidizing properties make it an effective agent for decontamination purposes.

Acetylcholine is a neurotransmitter. Neurotransmitters are chemical messengers that transmit signals between neurons in the brain and nervous system. Acetylcholine specifically plays a crucial role in various cognitive functions such as learning, memory, and muscle movement. It is released by nerve cells and binds to receptors on target cells, transmitting the signal across synapses. Therefore, acetylcholine is correctly classified as a neurotransmitter.

Reference materials are filed by subject to ensure easy access and organization. This method allows related materials to be grouped together, making it convenient for users to locate information on a specific topic. By organizing materials in this way, users can quickly find the relevant resources they need without having to search through unrelated materials. This filing system also facilitates efficient retrieval and promotes effective knowledge management.

Suprapubic aspiration is a procedure used to collect urine directly from the bladder using a needle inserted through the abdominal wall. This type of specimen is more likely to contain anaerobic bacteria, which thrive in the absence of oxygen. Therefore, it is necessary to store the specimen in an anaerobic environment to maintain the viability of these bacteria for further analysis.

Medicare Part A covers hospitalization for the patient. This means that it includes expenses related to inpatient care, such as hospital stays, skilled nursing facility care, hospice care, and limited home health services. It does not cover physician office visits or clinical laboratory services, which are typically covered under Medicare Part B.

Dacron swabs are commonly used for viral cultures because they have a high absorption capacity and are less likely to interfere with the growth of viruses. Dacron is a synthetic material that does not contain any substances that could inhibit viral growth, making it an ideal choice for collecting samples for viral culture. Additionally, Dacron swabs are flexible and easy to handle, allowing for efficient and accurate sample collection.

The word root "myc/o" is derived from the Greek word "mykes" which means fungus or mold. This root is commonly used in medical terminology to refer to conditions related to fungal infections or diseases caused by fungi. Therefore, "fungus or mold" is the correct meaning of the word root "myc/o".

Haemophilus ducreyi is the bacterium that causes chancroid, a sexually transmitted infection characterized by painful genital ulcers. Escherichia coli is a common bacterium found in the intestines and is not associated with chancroid. Rickettsia rickettsii is the bacterium that causes Rocky Mountain spotted fever, not chancroid. Salmonella typhi is responsible for causing typhoid fever, which is also unrelated to chancroid. Therefore, Haemophilus ducreyi is the correct answer for the bacterium that causes chancroid.

A normal spirometry test is expected to be above 80 percent of the predicted value. This means that if a person's spirometry test result falls below 80 percent of the predicted value, it may indicate a potential respiratory issue or impairment. It is important for individuals to have spirometry tests within the normal range to ensure proper lung function.

Cortisol is not an anabolic hormone because it has catabolic effects on the body. While anabolic hormones promote growth, cortisol is responsible for breaking down tissues and increasing blood sugar levels. It also suppresses the immune system and has anti-inflammatory effects. Therefore, cortisol does not fit the definition of an anabolic hormone.

There are seven tarsal bones in the human body. These bones are located in the foot and include the talus, calcaneus, navicular, cuboid, and three cuneiform bones. These tarsal bones play a crucial role in providing stability, support, and flexibility to the foot, allowing for various movements such as walking, running, and jumping.

The Federal Comprehensive Drug Abuse Prevention and Control Act of 1970 describes Schedule I drugs as drugs that have no acceptable medical use. This means that these drugs are not recognized as having any legitimate medical purpose and are considered to be highly dangerous and prone to abuse.

Vasodilators are not a treatment for Crohn's disease because they primarily work by widening blood vessels and increasing blood flow, which is not a targeted approach for the underlying inflammation and immune system dysfunction in Crohn's disease. Crohn's disease is typically treated with medications that reduce inflammation and suppress the immune system, such as steroids and anti-inflammatories. Vitamin B12 may also be used as a supplement to address deficiencies caused by malabsorption in Crohn's disease.

Adverbs are words that modify verbs, adjectives, or other adverbs. They provide information about when, where, why, or how something was done. Therefore, of the given options, adverbs are the only ones that fit this description. Nouns are not related to the action or manner of an event, while verbs and adjectives describe actions or qualities but do not specifically provide information on when, where, why, or how something was done.

Icterus is the correct answer because it is the term used to define serum or plasma that is brownish-yellow in color due to hyperbilirubinemia. Hyperbilirubinemia is a condition characterized by an excess of bilirubin in the blood, which can cause yellow discoloration of the skin and eyes. Therefore, the term icterus is used to describe the brownish-yellow coloration resulting from this condition.

Presbyopia is the most common eye condition associated with aging. It is a natural part of the aging process and occurs when the lens of the eye becomes less flexible, resulting in difficulty focusing on close objects. This condition typically becomes noticeable around the age of 40 and gradually worsens over time. It is different from other vision problems like astigmatism, glaucoma, and conjunctivitis, which can affect individuals of all ages.

The correct answer is "None" because an evacuated tube with a red stopper is typically used for serum tests, which require the blood sample to clot before it is centrifuged. Therefore, no additives are needed in this type of tube, as they are used in other types of tubes for different tests such as AIDS and blood chemistries.

The correct answer is Leads test. A Leads test is a type of test used in medical diagnostics to determine the presence or absence of certain substances in a patient's blood or urine. Unlike other QC tests such as Specimen test, Quantitative test, and Qualitative test, a Leads test does not have a control limit. This means that there is no specific range or threshold that the test results need to fall within to be considered acceptable. Instead, the presence or absence of the substance being tested for is simply determined based on the appearance of a positive or negative result.

The correct abbreviation for "seizure" is "Sz".

Sputum should be refrigerated after one hour because it is important to preserve the sample for accurate testing. After one hour, the sputum may start to degrade and bacteria or other pathogens present in the sample may begin to multiply, leading to inaccurate results. Refrigerating the sputum helps to slow down the growth of bacteria and preserve the integrity of the sample until it can be properly analyzed.

The correct answer is "Sounds develop into a squeaking quality." This is because the second phase of the blood pressure sound is known as the "murmur" phase, where the sounds change from a crisp quality to a more turbulent and squeaking quality.

Sodium hypochlorite is not a phenolic compound used for disinfection purposes. Phenolic compounds, such as phenic acid, phenylic acid, and hydroxybenzene, are commonly used as disinfectants for various surfaces. Sodium hypochlorite, on the other hand, is a chemical compound commonly known as bleach and is used as a disinfectant for water and other substances, but not specifically for walls, furniture, floors, or laboratory work surfaces.

The physician would violate the ethical principle of veracity if she does not inform her patient of the correct diagnosis. Veracity refers to the duty to tell the truth and be honest with patients. By withholding the information about the patient's terminal illness, the physician would be failing to fulfill her obligation to be truthful and transparent with the patient.

V4 is the correct answer because it is the electrode placement that goes at the fifth intercostal space, left of the midclavicular line. The V1, V2, and V3 electrode placements are located in different intercostal spaces or lines and are not the correct placements for this specific location.

Rationalization is a defense mechanism where individuals justify their behavior by providing socially-acceptable reasons, even if those reasons do not reflect the true underlying motives. This helps individuals avoid feelings of guilt or anxiety by creating a more acceptable narrative for their actions. It allows them to maintain a positive self-image and preserve their self-esteem.

UACDS, or Uniform Ambulatory Care Data Set, deals with the care provided to patients who return home on the day of service. This data set is specifically designed to collect information on outpatient services and is used to track and analyze ambulatory care provided to patients who are not admitted to a hospital or other healthcare facility. It includes data on diagnoses, procedures, and other relevant information related to outpatient care.

The two-digit modifier 62 is used to describe two surgeons who work together as primary surgeons during a surgical procedure. This modifier indicates that each surgeon has a distinct role and is responsible for a separate part of the procedure. The use of modifier 62 allows for appropriate billing and reimbursement for the services provided by both surgeons.

Wound specimens should be taken from the base or edge of the wound. This is because the base and edge of a wound are the areas where the highest concentration of bacteria and other microorganisms are typically found. By collecting specimens from these areas, healthcare professionals can obtain a more accurate representation of the microorganisms present in the wound, which can help guide appropriate treatment decisions.

The correct formula for converting Fahrenheit to Celsius is (F - 32) X 5 / 9= C. This formula subtracts 32 from the Fahrenheit temperature, then multiplies the result by 5 and divides it by 9 to get the equivalent Celsius temperature.

In catheter urine collection, the catheter tip should not be included because it is the part of the catheter that is inserted into the patient's body to collect urine. Including the catheter tip in the collection would not provide an accurate representation of the patient's urine sample.

Medical Malpractice Acts are laws enacted to define what is included in the practice of medicine. These acts establish the legal boundaries and standards for medical professionals, outlining their responsibilities, scope of practice, and acceptable standards of care. By clearly defining what falls under the practice of medicine, these laws aim to protect patients from potential harm and ensure that healthcare providers are held accountable for any negligence or malpractice.

Ventricular fibrillation is the correct answer because it is the most common cause of sudden cardiac death. Ventricular fibrillation is a condition in which the heart's electrical signals become chaotic, causing the heart to quiver instead of pumping blood effectively. This can lead to a sudden loss of consciousness and, if not treated immediately, can be fatal. Drowning and choking accidents can also cause sudden death, but ventricular fibrillation is the primary cause in most cases. Myocardial infarction, or a heart attack, can lead to ventricular fibrillation, making it a potential cause of sudden cardiac death as well.

A pterygium is a non-cancerous growth of the conjunctiva, which is the clear tissue that lines the eyelids and covers the white part of the eye. It usually appears as a fleshy, triangular-shaped tissue on the inner or outer corner of the eye. Pterygiums are typically caused by prolonged exposure to ultraviolet (UV) light, such as from sunlight, and can cause symptoms like redness, irritation, and blurred vision. Treatment options include lubricating eye drops, steroid eye drops, and surgery in severe cases.

An electrocardiogram (ECG) is a test that records the electrical activity of the heart. It is used to detect any abnormalities in the heart's rhythm and structure. In a twelve lead ECG, ten electrodes are placed on the patient's body to record the electrical signals from different angles or views of the heart. These views include the frontal plane (six leads) and the horizontal plane (four leads). Each lead provides unique information about the heart's electrical activity, allowing for a comprehensive assessment of its function. Therefore, the correct answer is 10 electrodes, 12 views of the heart.

Choreia refers to an involuntary movement. It is a neurological condition characterized by random, jerky, and uncontrollable movements of the body. These movements are often repetitive and may affect different parts of the body. Choreia can be caused by various factors, including genetic disorders, certain medications, or damage to the brain. The term choreia is derived from the Greek word "choreia," meaning dance, as the movements can resemble a dance-like pattern.

Dantrolene is used to treat malignant hyperthermia. Malignant hyperthermia is a potentially fatal reaction to certain medications used during general anesthesia. Dantrolene works by blocking the release of calcium in muscle cells, which helps to relax and prevent muscle contractions. It is the only medication specifically approved for the treatment of malignant hyperthermia. Baclofen, Danazol, and Danocine are not indicated for the treatment of malignant hyperthermia.

A cathartic medication is a type of laxative that is used to stimulate bowel movements and relieve constipation. It works by irritating the lining of the bowel, which increases the movement of the intestines and promotes the elimination of waste. This irritation helps to soften the stool and make it easier to pass.

The given definition describes a tort, which is a type of law that deals with civil wrongs that are not related to a contract or statute. In tort law, individuals who have been harmed by the actions of others can seek compensation for their damages. This can include cases of negligence, where someone fails to exercise reasonable care and causes harm to another person, as well as intentional wrongs like assault or defamation. Tort law aims to provide justice and compensation to those who have suffered harm due to the actions of others.

The term "suppurative" is used to describe something that contains pus. Pus is a thick yellowish or greenish fluid that is produced in response to an infection. When an area of the body becomes infected, white blood cells gather to fight off the infection, resulting in the formation of pus. Therefore, the term "suppurative" accurately describes a condition or situation where pus is present.

Level I tests are the most complex and require a higher level of expertise to perform. They include tests such as coagulation studies, blood urea nitrogen, and red and white blood cell counts. Urine cultures for colony counts, on the other hand, are classified as Level II tests, which are less complex and can be performed by individuals with less training. Therefore, the correct answer is coagulation studies, as they are not classified as Level I tests.

Clostridium botulinum is a pathogenic Gram-positive bacterium. It is responsible for causing botulism, a severe form of food poisoning. This bacterium produces a potent neurotoxin called botulinum toxin, which can lead to paralysis and even death if ingested. Clostridium botulinum is commonly found in soil and can contaminate improperly processed or preserved foods, such as canned goods. It is an anaerobic bacterium, meaning it thrives in environments with little to no oxygen.

Whole blood is the correct answer because it is collected in a tube with an anticoagulant, which prevents the blood from clotting. Since the anticoagulant is already present in the tube, there is no need to centrifuge the specimen to separate the blood components. This allows for the preservation of the blood's cellular and liquid components in their original state for further testing or analysis.

"In situ" refers to something being in its normal or original location. This term is often used in medical and scientific contexts to describe a condition or process that occurs naturally or remains undisturbed in its usual place. It can be contrasted with situations where something is manipulated or removed from its original location, such as in a test tube, a living organism, or a surgical setting.

Engineering controls are defined as structural or mechanical devices that are designed to minimize exposure to bloodborne pathogens. These controls include things like sharps containers, self-sheathing needles, and biohazard waste disposal systems. They are put in place to eliminate or reduce the risk of exposure to bloodborne pathogens in the workplace. Work practice controls, on the other hand, refer to procedures that are implemented to minimize the risk of exposure, such as hand hygiene and proper disposal of contaminated materials. Personal protective equipment refers to the protective clothing, gloves, masks, and eyewear that are worn to protect against exposure. Standard precautions are a set of infection control practices that are used to prevent the transmission of bloodborne pathogens and other infectious diseases.

The correct order of Maslow's "Hierarchy of Needs" starting from the bottom to the top is physiological needs, safety and security, love and belonging, esteem and recognition, self-actualization. This hierarchy suggests that individuals must first satisfy their basic physiological needs such as food, water, and shelter before moving on to higher-level needs such as safety, love, esteem, and ultimately self-actualization. This order implies that individuals cannot fully focus on higher-level needs until their lower-level needs are met.

The fibrous pericardium is the outermost of the pericardial membranes. It is a tough, fibrous layer that surrounds and protects the heart. The fibrous pericardium is made up of dense connective tissue and provides structural support to the heart, preventing overexpansion and protecting it from external forces. It also helps to anchor the heart in place within the chest cavity. The other options, such as the epicardium, visceral pericardium, and parietal pericardium, are all inner layers of the pericardial membranes.

Cortisol is a catabolic hormone because it promotes the breakdown of proteins, carbohydrates, and fats in the body. It helps to mobilize energy stores during times of stress or low blood sugar levels. This hormone also suppresses the immune system and has anti-inflammatory effects. Overall, cortisol plays a crucial role in regulating metabolism and responding to stress.

Fried's rule for pediatric dose calculations is outlined as the infant's age in months divided by 150 and multiplied by the average adult dose. This formula takes into account the age of the infant and adjusts the dose accordingly. By dividing the age in months by 150, it provides a more accurate dosage calculation for infants. Multiplying this result by the average adult dose ensures that the medication dosage is appropriate for the child's age and weight.

The ICD-9 contains four volumes which are used for different purposes in medical coding. Volume I is the Tabular list of diseases, which provides a comprehensive list of all diseases and their corresponding codes. Volume III is used for Inpatient coding, specifically for coding diseases and procedures related to hospital inpatient care. Volume II is the Alphabetical listing index of diseases, which allows users to look up diseases alphabetically and find their corresponding codes. Volume IV, mentioned in the question, does not exist in the ICD-9.

The jejunum is the correct answer because it is the middle part of the small intestine where most of the absorption of nutrients takes place. It has a large surface area due to its long length and numerous folds, allowing for efficient absorption of nutrients such as carbohydrates, proteins, and fats. The duodenum is the first part of the small intestine where initial digestion occurs, but absorption is limited. The ileum is the last part of the small intestine where some absorption occurs, but it is not the primary site. The large intestines mainly absorb water and electrolytes, not nutrients.
