CPC AAPC Practice Test Questions and Exam Dumps

Question 1

Based on the procedural note provided, which surgical approach was used in this operation?

A. Percutaneous
B. Laparoscopic
C. Cannot determine based on the documentation
D. Open

Correct Answer: D

Explanation:
The passage describes a detailed surgical procedure involving a skin incision and dissection through multiple layers of abdominal musculature. This description helps determine the nature of the surgical approach used.

Let’s break it down step by step:

The key phrases in the documentation include:

• “He was then sterilely prepped and draped along the flank and abdomen in the usual sterile fashion.”

• “I first made a skin incision off the tip of the twelfth rib, extending medially along the banger’s lines of the skin.”

• “This was approximately 3.5 cm in length.”

• “Once this incision was carried sharply, electrocautery was used to gain access through the external oblique, internal oblique, and transverse abdominis musculature and fascia.”

These details provide strong evidence that the open surgical approach was used:

1. Direct skin incision is a hallmark of an open procedure. The use of specific anatomical landmarks (e.g., tip of the twelfth rib) and a defined incision length (3.5 cm) are classic descriptions in open surgical documentation.

2. The mention of using electrocautery to dissect through layers of muscle (external oblique, internal oblique, and transverse abdominis) suggests a methodical and layered exposure of the surgical site, which is characteristic of open surgery.

3. The term “gaining access through fascia and musculature” further implies physical, direct entry via a traditional incision rather than using ports or trocars as in laparoscopic approaches.

Now let’s review the other options:

A. Percutaneous:
A percutaneous procedure involves a needle puncture or catheter insertion through the skin, typically without the need for cutting through muscle layers or making a 3.5 cm incision. The description clearly involves a surgical cut and dissection, so this does not qualify as percutaneous.

B. Laparoscopic:
Laparoscopic surgeries are minimally invasive and usually involve small port incisions (usually under 1 cm), insufflation of gas (often CO₂), and the use of cameras and instruments inserted through trocars. There is no mention of laparoscopic equipment, ports, scopes, or insufflation. Additionally, a 3.5 cm incision with deep muscular dissection is more typical of open procedures.

C. Cannot determine based on the documentation:
Although some documentation may be vague, this particular excerpt is detailed enough to support a confident determination. The specific mention of muscle layers being dissected and the nature of the incision allow us to reasonably conclude the surgical approach.

D. Open:
This is the most appropriate answer, as the passage describes a traditional open method involving a measurable incision and anatomical dissection through muscle layers. This is consistent with standard open surgical approaches used in flank or retroperitoneal surgeries.

Question 2
Which of the following best describes the mediastinum?

A. A location in the chest, bounded by the sternum, diaphragm, and lungs
B. A small endocrine organ behind the heart
C. A part of the lymphatic system
D. Both the heart and lungs

Correct Answer: A

Explanation:
The mediastinum is a central compartment located within the thoracic cavity. It plays a crucial role as the anatomical space that houses many of the vital organs and structures necessary for circulation, respiration, and immune function.

Let’s explore each option to understand why A is correct and the others are incorrect or misleading:

Option A: A location in the chest, bounded by the sternum, diaphragm, and lungs
This is the correct and most accurate anatomical description. The mediastinum is centrally located in the chest (thorax) and is bounded:

• Anteriorly by the sternum

• Posteriorly by the vertebral column

• Laterally by the lungs and pleural cavities

• Superiorly by the thoracic inlet

• Inferiorly by the diaphragm

The mediastinum is further subdivided into superior and inferior regions, and the inferior mediastinum is divided into anterior, middle, and posterior compartments. It contains several vital structures, including the heart, thymus, parts of the esophagus and trachea, major blood vessels (like the aorta and vena cavae), lymph nodes, and nerves.

Option B: A small endocrine organ behind the heart
This is incorrect. This option may be confusing the mediastinum with the thymus, which is a small endocrine and lymphoid organ located in the anterior part of the superior mediastinum, behind the sternum and in front of the heart. The thymus resides within the mediastinum, but the mediastinum itself is not an organ — it is an anatomical space.

Option C: A part of the lymphatic system
This is also incorrect. While the mediastinum contains lymph nodes and parts of the lymphatic system, it is not itself a component of that system. Again, the mediastinum is a space, not a system or organ.

Option D: Both the heart and lungs
This is inaccurate because although the heart is housed within the mediastinum, the lungs are not. The lungs reside in their own pleural cavities, which are located on either side of the mediastinum. The lungs flank the mediastinum but are not contained within it.

In summary, the mediastinum is best defined as a centrally located anatomical space in the thoracic cavity that is bounded by major thoracic structures and houses important organs, vessels, and tissues — primarily including the heart, great vessels, and parts of the respiratory and digestive tracts. Therefore, the correct answer is A.

Question 3

A patient has been diagnosed with dacryocystitis. What structure is affected by this inflammation?

A. Cornea
B. Fingernail
C. Eardrum
D. Lacrimal sac

Correct Answer: D

Explanation:
Dacryocystitis is a medical condition involving inflammation or infection of the lacrimal sac, which is part of the tear drainage system in the eye. This sac collects tears from the eye through small channels known as canaliculi and then drains them into the nasolacrimal duct. When the duct becomes blocked, it prevents the normal flow of tears, leading to stagnation and bacterial growth in the sac, causing dacryocystitis.

The condition commonly presents with symptoms such as pain, redness, and swelling near the inner corner of the eye (medial canthus), excessive tearing, and sometimes discharge from the eye. In more severe cases, fever and spreading cellulitis can occur.

Now let's consider the incorrect options:

A. Cornea – The cornea is the transparent front part of the eye that covers the iris and pupil. Inflammation of the cornea is called keratitis, not dacryocystitis. Keratitis may result from infection, trauma, or underlying disease, but it does not involve the tear drainage system.

B. Fingernail – The fingernail is completely unrelated to the ocular or tear drainage systems. Inflammation or infection involving the fingernail area is typically referred to as paronychia, which is distinct from any form of eye condition.

C. Eardrum – The eardrum, or tympanic membrane, is part of the auditory system. Infections or inflammation involving the eardrum are referred to as myringitis or otitis media, depending on the structures involved. These have no anatomical or functional relationship with the lacrimal sac or the tear system.

D. Lacrimal sac – This is the correct answer. The lacrimal sac is the small chamber into which tears drain from the eye before flowing into the nasolacrimal duct. In dacryocystitis, this sac becomes inflamed, often due to obstruction, and can lead to significant discomfort and possible infection if not treated properly.

Treatment of dacryocystitis usually begins with antibiotics to treat the infection. If the blockage persists or the infection is recurrent, surgical procedures such as dacryocystorhinostomy may be necessary to establish a new pathway for tear drainage.

In summary, dacryocystitis specifically affects the lacrimal sac, making D the most accurate and appropriate answer.

Question 4
What part of the face is reconstructed during a rhinoplasty procedure?

A. The nose is reconstructed
B. The brow is reconstructed
C. The lips are reconstructed
D. The chin is reconstructed

Correct Answer: A

Explanation:
Rhinoplasty is a surgical procedure that involves the reconstruction or reshaping of the nose. The term comes from the Greek words "rhinos" meaning nose and "plassein" meaning to shape. It is one of the most common cosmetic surgical procedures and can be performed for aesthetic, functional, or reconstructive purposes.

Aesthetic rhinoplasty is typically done to change the shape or size of the nose for cosmetic reasons, such as altering the nasal bridge, refining the tip, narrowing the nostrils, or adjusting the angle between the nose and upper lip. Functional rhinoplasty, on the other hand, aims to correct breathing issues caused by structural abnormalities like a deviated septum. Reconstructive rhinoplasty is often necessary following trauma, cancer resection, or congenital deformities.

Now let’s consider the incorrect options:

B. The brow is reconstructed – Surgical procedures that focus on the brow are called brow lifts or forehead lifts. These are done to reduce wrinkles or sagging in the forehead area but are unrelated to rhinoplasty.

C. The lips are reconstructed – Reconstruction or cosmetic enhancement of the lips is generally referred to as cheiloplasty or lip augmentation. This can involve reshaping, enlarging, or repairing defects of the lips, but it is a completely different procedure from rhinoplasty.

D. The chin is reconstructed – Chin surgery is known as genioplasty or mentoplasty. These procedures modify the shape, size, or position of the chin for either aesthetic or medical reasons, and they are distinct from nose surgeries.

Rhinoplasty may be performed using an open or closed technique. The open technique involves an external incision across the columella (the tissue between the nostrils), allowing better visualization and access to the nasal structures. The closed technique involves internal incisions only, resulting in no visible scarring but offering limited access.

Recovery from rhinoplasty can involve swelling, bruising, and nasal congestion for several weeks. Final results might not be fully visible until a year after surgery, as subtle changes continue to occur during healing.

Question 5
Where in the body is a Warthin's tumor typically located?

A. Ovary
B. Bone
C. Salivary gland
D. Back of eye

Correct Answer: C

Explanation:
A Warthin's tumor, also known as papillary cystadenoma lymphomatosum, is a benign tumor most commonly found in the salivary glands, particularly the parotid gland. This type of tumor accounts for about 5–10% of all salivary gland tumors and is the second most common benign neoplasm of the parotid, following pleomorphic adenoma.

Warthin's tumors usually occur in older adults, especially men over the age of 60, and have a strong association with smoking, which significantly increases the risk. Interestingly, it is one of the few salivary gland tumors that is more common in men than in women. The tumors are typically slow-growing, painless, and may be found on one or both sides of the face (bilateral in about 10% of cases, and multifocal in some).

Pathologically, Warthin’s tumor has a distinctive appearance under the microscope, featuring both epithelial and lymphoid components. It is cystic, often containing a brown fluid, and has papillary projections lined by a double layer of oncocytic (mitochondria-rich) epithelial cells, with underlying lymphoid tissue that may resemble lymph nodes.

Surgical excision is the standard treatment, and recurrence is uncommon if the tumor is completely removed. Importantly, Warthin's tumor is benign, meaning it does not metastasize or invade surrounding tissues, although it may grow over time.

Now, let’s review why the other options are incorrect:

A. Ovary – Tumors in the ovary can include benign and malignant forms such as dermoid cysts, serous cystadenomas, or epithelial ovarian cancers. Warthin's tumor does not occur in the ovary.

B. Bone – Bone tumors like osteoma, osteosarcoma, or Ewing's sarcoma are unrelated to Warthin’s tumor. Warthin's has no involvement with osseous structures.

D. Back of eye – Tumors of the eye or its surrounding structures include retinoblastomas, melanomas, or hemangiomas. Again, these are unrelated to Warthin’s tumor, which is specific to salivary glands.

Question 6
When a patient has ESRD, which body system is primarily affected?

A. Cardiovascular
B. Neurologic
C. Respiratory
D. Genitourinary

Correct Answer: D

Explanation:
ESRD stands for End-Stage Renal Disease, which refers to the final, most severe phase of chronic kidney disease in which the kidneys can no longer adequately perform their essential functions. As such, the genitourinary system is the primary system affected.

The kidneys are critical organs within the genitourinary system. Their primary roles include filtering waste products from the bloodstream, regulating electrolyte and fluid balance, maintaining blood pressure through hormonal control (like renin), and stimulating red blood cell production by releasing erythropoietin. In ESRD, these functions are lost or severely impaired.

Patients with ESRD typically require renal replacement therapy, which may involve dialysis (hemodialysis or peritoneal dialysis) or kidney transplantation to survive. Without treatment, toxic waste products and fluid buildup in the body would lead to systemic failure and death.

Let’s now examine the other options and explain why they are not the correct choice:

A. Cardiovascular – While the cardiovascular system is often secondarily affected in ESRD patients (e.g., due to hypertension or fluid overload), it is not the primary system involved. Cardiovascular complications are common in ESRD and represent a major cause of death in these patients, but the initial and primary disease process is in the kidneys, part of the genitourinary system.

B. Neurologic – Neurological symptoms, such as confusion, peripheral neuropathy, or seizures, may arise due to uremia (buildup of waste in the blood), but again, these are secondary manifestations of kidney failure, not the primary system affected.

C. Respiratory – The respiratory system can be affected by fluid overload or metabolic acidosis leading to rapid breathing, but as with the above, this occurs as a consequence of kidney failure and is not the root system involved in ESRD.

Question 7
The human shoulder is made of which three bones?

A. Olecranon, radius, ulna
B. Carpal, radius, humerus
C. Metatarsal, tibia, navicular
D. Clavicle, scapula, humerus

Correct Answer: D

Explanation:
The human shoulder is a highly mobile joint composed of three primary bones: the clavicle (collarbone), scapula (shoulder blade), and humerus (upper arm bone). These bones form the skeletal framework of the shoulder, enabling a wide range of motion and serving as the foundation for muscular attachments.

The clavicle connects the sternum (breastbone) to the scapula, helping to stabilize the shoulder and keep the arm away from the trunk. The scapula is a flat, triangular bone that serves as the attachment site for several important shoulder muscles and forms part of the shoulder socket (glenoid cavity). The humerus is the long bone of the upper arm that fits into the glenoid cavity of the scapula, forming the ball-and-socket joint of the shoulder (glenohumeral joint).

Let’s examine why the other options are incorrect:

A. Olecranon, radius, ulna – These bones are located in the elbow and forearm, not the shoulder. The olecranon is the bony prominence of the elbow (part of the ulna), and the radius and ulna are the two long bones of the forearm.

B. Carpal, radius, humerus – The carpal bones are part of the wrist, the radius is a forearm bone, and the humerus is the only one in this group that's also part of the shoulder. This combination does not represent the three bones of the shoulder joint.

C. Metatarsal, tibia, navicular – These are bones found in the foot and lower leg, not the shoulder. Metatarsals are foot bones, the tibia is a leg bone (shin), and the navicular is one of the tarsal bones in the foot.

Thus, the only correct grouping of bones that make up the shoulder is clavicle, scapula, and humerus, which are accurately listed in option D. These three bones work together to allow the shoulder joint its remarkable range of motion, supporting both gross and fine motor functions in the upper limb.

Question 8
What is the name of the skin's topmost layer that serves as the primary barrier protecting the body from external harm?

A. Epidermis
B. Hypodermis
C. Subcutaneous tissue
D. Dermis

Correct Answer: A

Explanation:
The epidermis is the outermost layer of the skin and functions as the body's first line of defense. It protects against environmental hazards such as bacteria, viruses, harmful chemicals, and UV radiation. Composed mainly of keratinocytes, this layer produces keratin, a protein that helps reinforce the skin’s toughness and waterproofing properties.

The epidermis does not contain blood vessels, so it relies on the underlying dermis for nutrient and waste exchange. It consists of multiple sublayers, with the stratum corneum being the outermost. This part is made of dead, flattened cells that continuously shed and renew.

In contrast, the hypodermis (also called the subcutaneous layer) lies beneath the dermis and contains fat and connective tissue. Its function is primarily insulation and cushioning, not protection from the external environment.

The dermis, situated between the epidermis and hypodermis, contains sensory nerves, blood vessels, and structures such as hair follicles and sweat glands. Although critical for sensation and thermoregulation, it is not the skin's outermost protective layer.

Subcutaneous tissue is synonymous with the hypodermis, and again, it is not involved in direct environmental defense.

Question 9
What are the names of the structures that make up the four internal chambers of the human heart?

A. Atria and ventricles
B. Apex and alveoli
C. Tricuspid and bicuspid
D. Sphincter and glottis

Correct Answer: A

Explanation:
The human heart consists of four main chambers: two atria (singular: atrium) and two ventricles. These chambers are responsible for receiving blood into the heart and pumping it out to the lungs and the rest of the body. The atria are the upper chambers — the right atrium receives deoxygenated blood from the body, and the left atrium receives oxygenated blood from the lungs. The ventricles are the lower chambers — the right ventricle pumps blood to the lungs, and the left ventricle pumps oxygenated blood to the rest of the body.

Option B, "apex and alveoli," is incorrect because the apex refers to the pointed lower tip of the heart, and alveoli are tiny air sacs in the lungs responsible for gas exchange, not part of the heart.

Option C, "tricuspid and bicuspid," refers to heart valves, not chambers. The tricuspid valve is located between the right atrium and right ventricle, while the bicuspid valve (also called the mitral valve) is located between the left atrium and left ventricle.

Option D, "sphincter and glottis," pertains to different parts of the body entirely. A sphincter is a circular muscle that controls the passage of substances in areas such as the digestive tract (e.g., the anal sphincter), and the glottis is part of the vocal apparatus in the larynx, involved in sound production and airway protection.

Question 10
Which of the following bones is found in the lower part of the human body, specifically the leg?

A. Humerus
B. Femur
C. Radius
D. Ulna

Correct Answer: B

Explanation:
The femur is the bone located in the lower extremity of the human body. It is the thigh bone and is the longest and strongest bone in the human skeleton. The femur connects the hip joint to the knee joint, playing a crucial role in supporting the body's weight during standing, walking, and running.

Option A, the humerus, is incorrect because it is found in the upper extremity, specifically in the upper arm, connecting the shoulder to the elbow.

Option C, the radius, is also incorrect as it is one of the two main bones in the forearm (the other being the ulna), located in the upper limb. The radius runs parallel to the ulna and is situated on the thumb side of the forearm.

Option D, the ulna, is likewise incorrect for this question, as it is the second forearm bone alongside the radius, located on the pinky side of the forearm, and is part of the upper extremity.

The femur is critical for mobility and supports nearly all activities that involve leg movement. It articulates with the pelvic bone at the hip and with the tibia and patella at the knee. Because of its size and importance in locomotion, it is frequently studied in both anatomical and forensic fields.
