Med Surg-Quiz 14 Flashcards
harmless neoplasm, dysplasia, or hyperplasia. Unable to spread.
Benign
neoplasm is detrimental to surrounding tissue health. Able to spread to other tissues
Malignant
Malignant cells break away from primary cite
Transported via blood or lymphatic system
Land at new tissue and start to invade
Metastases
=cancer= new growth
Neoplasm
Slow-growing malignancy
Surface cancer
Non-invasive to blood or subcutaneous tissues
Basal Cell Carcinoma
Slow growing, but can become invasive to surrounding tissues;
Squamous Cell Carcinoma
Highly invasive
Fast growing
DEADLY – quick metastasis to lymphatics Early excision has a 5 year survival rate of 90%
Melanoma
A need to urinate frequently, especially at night
Difficulty starting urination or holding back urine
Inability to urinate
Weak or interrupted flow of urine
Painful or burning urination
Painful ejaculation
Blood in urine or semen
Frequent pain or stiffness in the lower back, hips, or upper thighs
S/S of Prostate Cancer
removal of the entire prostate, the seminal vesicles, a portion of the bladder neck, and regional lymph nodes
Radical prostatectomy
During this, a cystoscope is inserted into the bladder through the urethra. A small wire loop on the end is used to remove the cancerous area and to burn away any remaining cancer cells with an electric current.
Transurethral resection of the prostate (or TURP)
Cigarette smoking is directly responsible for most cases of this.
Bladder Cancer Risk Factors
The doctor may treat early stages with this. During this, a cystoscope is inserted into the bladder through the urethra. A small wire loop on the end is used to remove the cancerous area and to burn away any remaining cancer cells with an electric current.
Transurethral resection (TUR)
is the removal of the entire bladder, the nearby lymph nodes, part of the urethra, and the nearby organs that may contain cancer cells. In men, the nearby organs that are removed are the prostate, seminal vesicles, and part of the vas deferens. In women, the uterus, ovaries, fallopian tubes, and part of the vagina are removed.
Radical cystectomy
onset age between 20-40. Begins with a single involved lymph node that then progresses in a direct line along the chain of nodes and spreads to the organs via lymph system.
Hodgkin’s Lymphoma
Diagnosed by Reed-Sternberg cells (specific type of abnormal lymphocytes) 90% survival rate.
Hodgkin’s Lymphoma
Begins at nodes throughout the body and progresses to metastasis easily. Many different types. Involves mutation of T or B lymphocytes. “Approximately 30 to 60 percent of patients with an aggressive form of this can be cured.”
Non-Hodgkin’s Lymphoma
Attacks the immune system and produces lesions along bones, creating fractures and weakening of skeletal system.
Multiple Myeloma
refers to genetic defects that were present at birth.
Congenital
when there is a single X chromosome and no corresponding X or Y. (Denoted as “Monosomy X” or XO). *Refer to nondisjunction slide.
Presents as:
Female body, although abnormally developed.
Short stature
Broad neck
Broad, flattened chest with widespread nipples
Usually spontaneously aborted. Occurrence at birth is 1 : 2500 female births. Will be sterile.
Turner’s Syndrome
A nondisjunction occurs during meiosis. The female egg is left with two X chromosomes. Then the male sperm adds its X chromosome, resulting in (XXX).
Triple X Syndrome
A nondisjunctioned XY sperm chromosome meets with the X female egg chromosome resulting in XXY.
Klinefelter’s Syndrome
Down Syndrome
Trisomy 21
5th chromosome is missing the short end
Cri-Du-Chat Syndrome
“Brittle Bone Disease”
Osteogenesis Imperfecta
Chloride transport inhibited
Cystic FIbrosis
Linked to defective 15th chromosome, chronic insatiable hunger
Prader Willi Syndrome
Lack of specific clotting factors: type A, B, or C
Hemophilia
mutation of the dystrophin gene on the X chromosome.
Duchenne’s Muscular Dystrophy
Common cause of dwarfism
Achondroplasia
incomplete fusion of the posterior vertebral arch.
Spina Bifida
external protrusion of the meninges (membranes covering the spinal cord)
Meningocele
external protrusion of the meninges and spinal cord.
Myelomeningocele
Etiology- Folic acid deficiency
Neural Tube Deformities
