Free CMA: Medical Terminology & Anatomy Question and Answers — Questions and Answers

Question 1: Which of the following would be found in the mediastinum?

Left carotid artery
Pancreas
Aorta (Correct answer)
Occipital lobe

Correct answer: Aorta

The mediastinum is the central compartment of the thoracic cavity, located between the lungs. It houses several vital organs and structures, including the heart, great vessels like the aorta, trachea, esophagus, and thymus gland. The aorta, being the largest artery in the body, originates from the left ventricle of the heart and ascends through the mediastinum before arching and descending.

Question 2: When an impulse is transferred from one neuron to another, it happens at:

Synapse (Correct answer)
Terminal plate
Nerve center
Dendrite

Correct answer: Synapse

A synapse is the specialized junction where an electrical or chemical signal is transmitted from one neuron to another, or from a neuron to an effector cell like a muscle or gland. This critical point of communication allows nerve impulses to travel throughout the body, enabling functions like thought, movement, and sensation. Neurotransmitters are released into the synaptic cleft to facilitate this transmission.

Question 3: Which of the following terms has the wrong spelling?

Bacterium
Bacterial
Bacteriolagy (Correct answer)
Bacteriocidal

Correct answer: Bacteriolagy

The correct spelling for the study of bacteria is 'Bacteriology,' not 'Bacteriolagy.' The suffix '-ology' means 'the study of,' and the root 'bacteri-' refers to bacteria. Recognizing common spelling patterns and suffixes is essential for medical assistants to maintain accuracy in documentation and communication.

Question 4: What is the sequence in which urine moves through the urinary system in a human?

Urethra, bladder, ureter, kidney, urethral meatus
Bladder, urethra, kidney, urethral meatus, ureter
Bladder, kidney, ureter, urethra, urethral meatus
Kidney, ureter, bladder, urethra, urethral meatus (Correct answer)

Correct answer: Kidney, ureter, bladder, urethra, urethral meatus

Urine is produced in the kidneys, then travels down the ureters to be stored in the bladder. When the bladder is full, urine exits the body through the urethra and finally out of the urethral meatus. This sequence ensures proper filtration, storage, and elimination of waste products from the body.

Question 5: Which bone is placed below the ischium and above the patella?

Femur (Correct answer)
Ulna
Tibia
Calcaneus

Correct answer: Femur

The femur, or thigh bone, is located between the ischium (part of the hip bone) and the patella (kneecap). It is the longest and strongest bone in the human body. The ischium is inferior to the ilium and superior to the patella, placing the femur in the correct anatomical position relative to these structures.

Question 6: Which area of the abdomen is closest to the sternum?

Hypogastric
Epigastric (Correct answer)
Umbilical
Lumbar

Correct answer: Epigastric

The epigastric region is the upper central part of the abdomen, situated directly below the sternum and above the umbilical region. It is a common site for pain associated with conditions affecting the stomach, pancreas, or gallbladder. Understanding abdominal quadrants and regions is crucial for accurately describing patient symptoms and findings.

Question 7: The right ventricle of the heart pumps blood into the:

Pulmonary artery (Correct answer)
Pulmonary vein
Left ventricle
Right atrium

Correct answer: Pulmonary artery

The right ventricle of the heart is responsible for pumping deoxygenated blood into the pulmonary artery. This artery then carries the blood to the lungs, where it picks up oxygen and releases carbon dioxide. This is a crucial step in the pulmonary circulation, preparing the blood to return to the left side of the heart for systemic circulation.

Question 8: Which of the following details would be shown on a patient's Medicare card's front?

They may be made without preauthorization from the insurance carrier
A 15-year-old girl living with her parents
Unsaturated fats
The name of the beneficiary and the patient's ID number (Correct answer)

Correct answer: The name of the beneficiary and the patient's ID number

A patient's Medicare card displays essential identification information, including the beneficiary's full name and their unique Medicare Beneficiary Identifier (MBI). This information is vital for healthcare providers to verify eligibility and process claims for Medicare services. It does not typically include details about preauthorization or specific health conditions.

Question 9: The following are all recommended bookkeeping practices, EXCEPT

Completing bookkeeping once every two weeks (Correct answer)
One breath every 5 seconds
4 years
Muscle, nervous, epithelial, and connective

Correct answer: Completing bookkeeping once every two weeks

Completing bookkeeping once every two weeks is not a recommended practice for medical offices. Bookkeeping should ideally be done daily or at least weekly to ensure accuracy, catch errors promptly, and maintain up-to-date financial records. Regular bookkeeping helps in managing accounts receivable, tracking expenses, and ensuring financial stability.

Question 10: Which of the following incoming calls should the medical assistant transfer immediately to the physician?

The emergency room calling about admitting an established patient with chest pain (Correct answer)
Generic
Charges for a patient's office visit
Res ipsa loquitur

Correct answer: The emergency room calling about admitting an established patient with chest pain

An incoming call from the emergency room regarding an established patient with chest pain indicates a critical medical emergency. This situation requires immediate attention from the physician due to the potential for a life-threatening cardiac event. Transferring such calls promptly ensures the patient receives timely and appropriate medical care.

Question 11: Which of the following phrases describes a lymph node's surgical removal?

Perspiration
Lymphadenectomy (Correct answer)
Lymphangiography
Regency

Correct answer: Lymphadenectomy

The term 'lymphadenectomy' refers to the surgical removal of one or more lymph nodes. This procedure is often performed to diagnose or treat various conditions, particularly in oncology, to check for the spread of cancer. Understanding medical terminology is essential for accurate communication and documentation in a healthcare setting.

Question 12: The dorsalis pedis pulse is detected in which of the following areas of the body?

Bottom of the foot
Calf of the leg
Swelling of the testes
Top of the foot (Correct answer)

Correct answer: Top of the foot

The dorsalis pedis pulse is located on the top (dorsal aspect) of the foot, specifically lateral to the extensor hallucis longus tendon. Palpating this pulse is a common assessment technique to evaluate peripheral circulation in the lower extremities. Its presence indicates adequate blood flow to the foot.

Question 13: The best way to handle an unidentified caller who insists on speaking with the physician but refuses to give her phone number or the reason for her call would be to

Confirm office coverage for patient's insurance plan
Ask the caller to send a letter to the physician (Correct answer)
The claim will e denied, and the physician will not receive payment
All elderly patients have difficulty walking

Correct answer: Ask the caller to send a letter to the physician

When an unidentified caller insists on speaking with the physician but refuses to provide their name, number, or reason for the call, the most professional and secure approach is to ask them to send a letter. This protects patient privacy and the physician's time, as direct communication without identification can pose security risks or be unproductive. It avoids giving out physician contact information unnecessarily.

Question 14: Who registers doctors to provide prescriptions for prohibited substances?

0.8cc
Drug Enforcement Administration (DEA) (Correct answer)
Center for disease control and prevention
Fda

Correct answer: Drug Enforcement Administration (DEA)

The Drug Enforcement Administration (DEA) is the federal agency responsible for regulating controlled substances and registering healthcare providers who are authorized to prescribe them. Physicians must obtain a DEA registration number to legally prescribe medications classified as controlled substances. This ensures proper oversight and prevents drug diversion.

Question 15: The doctor instructs the medical assistant to take a blood sample for a chemical and hematological test. What is the proper draw order?

One breath every 5 seconds
Over the apex of the heart
Gold, then lavender-topped (Correct answer)
Prothromboplastin time (ptt)

Correct answer: Gold, then lavender-topped

When drawing blood for both chemical and hematological tests, the proper order of draw is crucial to prevent cross-contamination of additives between tubes, which could affect test results. A common order is gold-topped tubes (containing a gel separator and clot activator for chemistry tests) followed by lavender-topped tubes (containing EDTA for hematology tests like CBC). This sequence minimizes interference and ensures accurate lab results.

Question 16: Which of the subsequent statements exemplifies stereotyping?

Errors in their thinking
A lot of patients have memory lapses
All elderly patients have difficulty walking (Correct answer)
Leukocytes are responsible for blood clotting

Correct answer: All elderly patients have difficulty walking

Stereotyping involves making oversimplified and often negative generalizations about an entire group of people, rather than recognizing individual differences. The statement 'All elderly patients have difficulty walking' is a clear example of stereotyping because it assumes a characteristic for every person in a demographic group, which is inaccurate and can lead to biased care. Not all elderly individuals experience mobility issues.
