Ch. 2 Q & A Flashcards
A patient sustaining an injury to her great saphenous vein would have sustained an injury to which of the following anatomical sites?
A. Neck
B. Arm
C. Leg
D. Abdomen
C. Leg
RATIONALE: The great saphenous vein carries blood from the great toe up the leg to the thigh, where it drains into the femoral vein. The great saphenous vein is sometimes harvested for use in multiple coronary artery bypass or peripheral artery bypass surgeries. Any confusion regarding venous anatomy can be cleared up by consulting the anatomy chart at the front of your CPT® Professional code book.
Which of the following is a function of the pancreas?
A. Supplies digestive enzymes
B. Manufactures melatonin
C. Stimulates growth
D. Secretes vasopressin
A. Supplies digestive enzymes
RATIONALE: The pancreas is part of the endocrine system, producing insulin that helps control blood sugars. But it is an exocrine gland, producing digestive enzymes that are carried by ducts to the small intestine to aid in the digestion of food. The pineal gland manufactures melatonin, thyroxine, and triiodothyronine are secreted by the thyroid gland to stimulate growth. The pituitary gland produces vasopressin, which raises the blood pressure. The answer to this question can be inferred by discovering that pancreatitis and other pancreas disorders are indexed in ICD-10-CM Alphabetic Index to the digestive system chapter.
Sebaceous glands are a part of which anatomic system?
A. Circulatory
B. Endocrine
C. Genitourinary
D. Integumentary
D. Integumentary
RATIONALE: Sebaceous glands are small oil-producing glands in the hair follicles and skin. As such, they are part of the integumentary system. The oil, called sebum, produced by these glands lubricates the skin and hair to protect it from dryness and irritation. Hormones can affect the secretion of sebum, and poor hygiene can result in its build-up. Either of these circumstances can lead to acne.
Which of the following has a refraction function in the eye?
A. Macula
B. Retina
C. Lens
D. Iris
C. Lens
RATIONALE: Refraction is the bending of light to focus the image. This can be artificially accomplished with eyeglasses, contact lenses, corneal surgery, or intraocular lenses. In the natural eye, all transparent elements on the pathway to the retina help in refraction: the cornea, aqueous, lens, and vitreous. Therefore, C is correct.
The myocardium is thickest around with chamber of the heart?
A. Right atrium
B. Left atrium
C. Right ventricle
D. Left ventricle
D. Left ventricle
RATIONALE: Myocardium is hear muscle. The heart consists of four chambers. Deoxygenated blood enters into right atrium through superior or inferior vena cava to begin the cycle. From here, the tricuspid valve opens and blood drops into the right ventricle. Next, the pulmonary valve opens, and deoxygenated blood moves through it in to the pulmonary artery. The pulmonary artery carries the blood into the lungs, where it picks up oxygen from the capillary beds. Next, the pulmonary vein brings oxygenated blood back to the left atrium. The mitral valve opens and blood flows into the left ventricle. The left ventricle is responsible for pushing the oxygenated blood out into the body and has a muscle mass that is much greater than any other chamber in the heart.
The tunica vaginalis is part of which system?
A. Male reproductive
B. Female reproductive
C. Urinary
D. Musculoskeletal
A. Male reproductive
RATIONALE: The tunica vaginalis is part of the male reproductive system, securing the testes, which are suspended by a rope-like structure called the spermatic cord. This cord is composed of a number of parts including arteries, veins, nerves, lymphatics, and connective tissue. Surrounding the testes is the tunica vaginalis, which keeps the testes from twisting or otherwise dislocating. Tunica vaginalis is indexed in the CPT® code book. All codes classified under this entry reference the Male Reproductive System subsection of the Surgery section of CPT®.
Complete this series: Incus, stapes,
A. Radius
B. Isthmus
C. Meatus
D. Malleus
D. Malleus
RATIONALE: The middle ear contains three ossicles, or small bones, commonly called the hammer (malleus), anvil (incus), and stirrup (stapes). Vibrations on the tympanic membrane are carried through these three interconnected bones to the oval window and the labyrinth of the inner ear. Illustrations of the ear can be found in your CPT® Professional and ICD-10-CM code books.
Hemiplegia is a disorder caused by a defect in which anatomic system?
A. Musculoskeletal
B. Nervous
C. Digestive
D. Intagumentary
B. Nervous
RATIONALE: Hemiplegia may cause problems with other body systems but has its roots in the nervous system. Hemiplegia is a paralysis or reduced movement of one side of the body. The underlying cause of any hemiplegia is going to be damage to the brain, which is part of the nervous system. In the ICD-10-CM Alphabetic Index look for the main term hemiplegia referring you to G81.9. In the Tabular List category code G81 falls in Chapter 6: Diseases of the Nervous System.
What is the result of a ureteral blockage?
A. Urine will not be able to flow for the kidney to the bladder.
B. Urine will not be able to flow from the bladder to the urethra.
C. Urine will not be able to flow from the bladder to the kidney.
D. Urine will not be able to be voided but will be trapped in the bladder.
A. Urine will not be able to flow from the kidney to the bladder.
RATIONALE: The body has ureters, each about a foot long. One extends from each of the kidneys to the bladder. A block in the ureter would prevent urine from traveling from the kidney to the bladder. This type of blockage can be caused by ureteral stones; inflammation due to underlying disease; kinks or fibrosis; or neoplastic growth.
Which of the following is a renal calculus?
A. Pyelectasia
B. Hydroureter
C. Nephrolithiasis
D. Pyonephrosis
C. Nephrolithiasis
RATIONALE: Renal calculus is a synonym for kidney stone, or nephrolithiasis. Pyel(o)- is a Greek root relating to the pelvis of the kidney, and nephr(o)- is a Greek root relating to the kidney, so all of these terms relate to the kidney. The suffix -ectasia refers to dilation or expansion; hydro- refers to the accumulation of fluid, and pyo- refers to pus. The right answer includes the root -litho, a Greek form identifying a stone or calculus. In the ICD-10-CM Alphabetic Index look for Calculus/renal – see Calculus, kidney. Calculus/kidney refers you to code N20.0. In the Tabular List you will see Nephrolithiasis listed under the code
