Free C804 - Medical Terminology Exam Questions
Situation: Tracy, 45/F, is diagnosed with nephrosclerosis. She was brought to the ER after noting edema and a BP of 160/100 mmHg.
Which statement BEST describes nephrosclerosis?
-
It is an autosomal recessive disorder characterized by hardened nephrons
-
Diabetes is the most common reason for its development
-
The renal arteries lose their elasticity and becomes stiff
-
It usually follows an episode of maltreated GABHS infection
Explanation
Explanation:
Nephrosclerosis is a condition characterized by the thickening and hardening of the small arteries and arterioles in the kidneys, leading to reduced blood flow and kidney function. The hallmark feature is the loss of elasticity and stiffening of the renal arteries, which contributes to hypertension and can result in chronic kidney damage. This condition is most commonly associated with chronic high blood pressure rather than being a genetic disorder, diabetic complication, or post-infectious sequela.
Correct Answer:
The renal arteries lose their elasticity and becomes stiff
Why Other Options Are Wrong:
It is an autosomal recessive disorder characterized by hardened nephrons
Nephrosclerosis is not a genetic disorder but a vascular condition caused primarily by chronic hypertension. The term refers to arterial changes, not an inherited pattern of nephron hardening, making this option incorrect.
Diabetes is the most common reason for its development
While diabetes can lead to kidney disease (diabetic nephropathy), nephrosclerosis is more specifically associated with hypertension, not diabetes. Diabetes is a separate etiology and not the primary cause of nephrosclerosis.
It usually follows an episode of maltreated GABHS infection
Post-streptococcal glomerulonephritis can occur after a GABHS infection, but nephrosclerosis is unrelated to infections and develops primarily from chronic arterial damage due to high blood pressure. This makes this option inaccurate.
In medical terminology, what does the abbreviation 'BUN' specifically measure in relation to kidney function?
-
Blood Urea Nitrogen
-
Blood Uric Nephron
-
Bicarbonate Urea Nitrogen
-
Blood Urine Nitrate
Explanation
Explanation:
The abbreviation 'BUN' stands for Blood Urea Nitrogen. It measures the amount of nitrogen in the blood in the form of urea, which is a waste product produced by the liver and excreted by the kidneys. BUN levels are used clinically to assess kidney function, as elevated levels may indicate impaired renal excretion, dehydration, or other kidney-related issues. It is a key laboratory marker in nephrology and general medical evaluations.
Correct Answer:
Blood Urea Nitrogen
Why Other Options Are Wrong:
Blood Uric Nephron
This is incorrect because 'BUN' does not measure uric acid or nephrons directly. Uric acid levels are assessed separately, and nephrons are structural units of the kidney, not directly measured by BUN.
Bicarbonate Urea Nitrogen
This is incorrect because bicarbonate is unrelated to the definition of BUN. BUN specifically measures nitrogen from urea, not bicarbonate levels in the blood.
Blood Urine Nitrate
This is incorrect because nitrates in blood or urine are not measured by BUN. BUN assesses nitrogen from urea, not nitrate content, making this option incorrect in relation to kidney function testing.
A bladder herniation refers to
-
varicocele
-
ureterocele
-
cystocele
-
hiatal hernia
Explanation
Explanation:
Herniation of the urinary bladder is referred to as a cystocele. This occurs when the supportive tissue between a woman’s bladder and vaginal wall weakens, allowing the bladder to protrude into the vagina. The suffix '-cele' denotes a hernia or protrusion, and 'cysto-' refers to the bladder, which together define the condition accurately. Cystocele can cause urinary symptoms such as difficulty emptying the bladder or increased frequency of urination.
Correct Answer:
cystocele
Why Other Options Are Wrong:
varicocele
This is incorrect because a varicocele is an enlargement of veins within the scrotum and is unrelated to the bladder. It is a vascular condition, not a herniation of the urinary organ.
ureterocele
This is incorrect because a ureterocele is a congenital dilation of the distal ureter as it enters the bladder. It does not involve herniation of the bladder itself.
hiatal hernia
This is incorrect because a hiatal hernia involves the protrusion of part of the stomach through the diaphragm into the thoracic cavity. It is unrelated to the urinary bladder.
In medical language, what does the suffix "-emia" mean?
-
Condition of blood
-
Inflammation of tissue
-
Abnormal growth
-
Surgical removal
Explanation
Explanation:
The suffix "-emia" in medical terminology refers to a condition of the blood. It is commonly used to describe the presence of a specific substance or abnormality in the blood. For example, "anemia" indicates a deficiency of red blood cells or hemoglobin in the blood, and "bacteremia" refers to the presence of bacteria in the bloodstream. This suffix specifically relates to blood conditions rather than inflammation, abnormal growth, or surgical procedures.
Correct Answer:
Condition of blood
Why Other Options Are Wrong:
Inflammation of tissue
Inflammation of tissue is indicated by the suffix "-itis," such as in "appendicitis" or "arthritis." The suffix "-emia" does not describe inflammation, making this option incorrect.
Abnormal growth
Abnormal growth is typically denoted by the suffix "-oma," as in "carcinoma" or "lipoma." Using "-emia" to describe growth is inaccurate.
Surgical removal
Surgical removal is indicated by the suffix "-ectomy," such as "appendectomy" or "tonsillectomy." "-Emia" does not refer to a surgical procedure, so this option is wrong.
What is the medical term used to describe discomfort or pain in the prostate gland?
-
Prostatitis
-
Prostatodynia
-
Prostatectomy
-
Benign prostatic hyperplasia
Explanation
Explanation:
The medical term for discomfort or pain in the prostate gland is Prostatodynia. The suffix '-dynia' refers to pain, and 'prostato-' refers to the prostate gland. This term specifically denotes pain localized to the prostate without necessarily implying inflammation or other pathological changes, distinguishing it from other prostate-related conditions.
Correct Answer:
Prostatodynia
Why Other Options Are Wrong:
Prostatitis
This is incorrect because prostatitis refers to inflammation of the prostate, which may or may not involve pain. While pain can be a symptom, prostatitis is a broader diagnosis encompassing inflammation, infection, and other symptoms.
Prostatectomy
This is incorrect because prostatectomy refers to the surgical removal of the prostate gland. It is a procedure, not a term describing pain or discomfort.
Benign prostatic hyperplasia
This is incorrect because benign prostatic hyperplasia (BPH) describes noncancerous enlargement of the prostate. While BPH may cause urinary symptoms, it does not specifically denote pain in the prostate.
What does the suffix '-malacia' indicate when used in medical terminology?
-
Inflammation of tissue
-
Softening of tissue
-
Hardening of tissue
-
Abnormal growth of tissue
Explanation
Explanation:
The suffix "-malacia" denotes softening of tissue in medical terminology. It is commonly used in terms like "osteomalacia," which describes the softening of bones due to defective mineralization. This suffix indicates a change in tissue consistency rather than inflammation, abnormal growth, or hardening, making softening of tissue the correct meaning.
Correct Answer:
Softening of tissue
Why Other Options Are Wrong:
Inflammation of tissue
Inflammation of tissue is indicated by the suffix "-itis," such as in "arthritis" (inflammation of joints). "-malacia" does not imply inflammation, making this option incorrect.
Hardening of tissue
Hardening of tissue is represented by the suffix "-sclerosis," as in "arteriosclerosis" (hardening of the arteries). Using "-malacia" to indicate hardening would be inaccurate.
Abnormal growth of tissue
Abnormal growth of tissue is typically denoted by suffixes like "-plasia" or "-oma." "-malacia" refers specifically to softening, not growth, so this option is incorrect.
The male gonad is which of the following?
-
Testosterone
-
Sperm
-
Spermatid
-
Testis
-
Penis
Explanation
Explanation:
The male gonad is the testis, which is responsible for producing sperm and secreting male sex hormones, primarily testosterone. The testis is the primary reproductive organ in males, analogous to the ovary in females. While sperm are the gametes produced by the testis, and spermatids are immature sperm cells, these are products of the gonad rather than the gonad itself.
Correct Answer:
Testis
Why Other Options Are Wrong:
Testosterone
Testosterone is a hormone produced by the testis, not the gonad itself. It plays a critical role in male sexual development and reproductive function but is a product, not the organ.
Sperm
Sperm are the male reproductive cells generated by the testis. They are the product of the gonad, not the gonad itself, so this option is incorrect.
Spermatid
Spermatids are immature sperm cells in the process of development within the testis. While they originate from the gonad, they are not the gonad itself, making this option inaccurate.
Penis
The penis is the external male reproductive organ used for copulation and urination. It is not a gonad and does not produce gametes or hormones, making this option incorrect.
In medical terms, what does the prefix "crypt-" mean?
-
Hidden
-
Excessive
-
Inflammation
-
Enlargement
Explanation
Explanation:
The prefix 'crypt-' in medical terminology signifies "hidden" or "concealed." It is commonly used to describe structures that are not easily visible or that are located in a concealed position. For example, 'cryptorchidism' refers to undescended (hidden) testes. Recognizing this prefix is important for accurately describing anatomical anomalies or conditions involving concealed organs or tissues.
Correct Answer:
Hidden
Why Other Options Are Wrong:
Excessive
This is incorrect because the prefix for excessive is 'hyper-.' 'Crypt-' does not indicate quantity or overabundance, but rather concealment.
Inflammation
This is incorrect because inflammation is indicated by the suffix '-itis,' such as in 'appendicitis.' 'Crypt-' does not refer to inflammatory processes.
Enlargement
This is incorrect because enlargement is indicated by the suffix '-megaly.' 'Crypt-' refers to hidden or concealed structures, not size or growth.
When one or both testicles do not descend into the scrotum, what medical name is used to describe this condition?
-
Testicular torsion
-
Cryptorchidism
-
Hydrocele
-
Orchitis
Explanation
Explanation:
The condition where one or both testicles have not descended into the scrotum is called Cryptorchidism. This congenital condition occurs when the testes fail to move from the abdomen or inguinal canal into the scrotal sac before birth. Cryptorchidism can increase the risk of infertility and testicular cancer if left untreated, making early diagnosis and management important in pediatric care.
Correct Answer:
Cryptorchidism
Why Other Options Are Wrong:
Testicular torsion
This is incorrect because testicular torsion refers to the twisting of the spermatic cord, which can cut off blood supply to the testicle. It is an acute, painful condition, not a failure of descent.
Hydrocele
This is incorrect because hydrocele refers to the accumulation of fluid around the testicle, causing swelling. It does not involve undescended testes.
Orchitis
This is incorrect because orchitis refers to inflammation of the testicle, often due to infection. It does not describe a developmental failure of testicular descent.
In medical terms, what does the suffix "-uria" mean?
-
Condition of urine
-
Inflammation of the bladder
-
Excessive thirst
-
Painful urination
Explanation
Explanation:
The suffix '-uria' in medical terminology refers to a condition of the urine. It is used to describe the presence, composition, or abnormalities of urine. For example, 'hematuria' indicates blood in the urine, and 'glycosuria' refers to sugar in the urine. This suffix is critical in clinical assessments because it helps identify specific urinary disorders or systemic conditions affecting urine composition.
Correct Answer:
Condition of urine
Why Other Options Are Wrong:
Inflammation of the bladder
This is incorrect because inflammation of the bladder is indicated by the suffix '-itis,' specifically 'cystitis,' not '-uria.' '-Uria' describes characteristics of the urine itself, not inflammation.
Excessive thirst
This is incorrect because excessive thirst is termed 'polydipsia,' which does not relate to urine composition or characteristics. '-Uria' is concerned with urine, not the sensation of thirst.
Painful urination
This is incorrect because painful urination is called 'dysuria.' The suffix '-uria' alone does not imply pain; it merely refers to the condition or content of the urine.
