Exam 3 Flashcards
Key topics for Exam 3
Stress urinary incontinence
increased abdominal pressure; A loss of urine of less than 50 mL occurring with increased abdominal pressure
Reflex/overflow urinary incontinence
overflow-zero awareness of need; full bladder and starts to overflow-paralyzed patients; surgical patients need straight cath; An involuntary loss of urine, occurring at somewhat predictable intervals when a specific bladder volume is reached
Urge urinary incontinence
sudden desire; UTI; Involuntary passage of urine occurring soon after a strong sense of urgency to void
Functional urinary incontinence
sudden, mobility barrier; usually dementia patients that are mobile; Inability of a usually continent person to reach toilet in time to avoid unintentional loss of urine
Total urinary incontinence
Continuous; A continuous and unpredictable loss of urine
Urinary retention
Incomplete emptying of the bladder
Urinary hesitancy
refers to a delay in starting the urine stream, commonly with a decreased force of the stream.
Urinary frequency
urination that occurs at shorter-than-usual intervals without an increase in daily urine output.
Urinary urgency
a sudden, forceful urge to urinate
Dysuria
difficult or painful urination.
Oliguria
diminished, scanty amount of urine.
anuria
absence of urine, usually clinically defined as less than 100 mL in 24 hours. It occurs in renal failure, shock, or dehydration.
polyuria
an excess amount of urine; it is usually associated with diabetes mellitus (a disturbance in the utilization of glucose secondary to inadequate production of insulin) or diabetes insipidus (caused by failure of the pituitary gland to secrete the antidiuretic hormone). Polyuria also may be caused by excess intake; greater than 2000 mL in 24 hrs
Enuresis
recurrent involuntary urination that occurs during sleep.
nocturia
nighttime urination
bacteriuria
Cloudiness indicates the presence of bacteria in urine
normal urine pH
pH range for urine is 4.5 to 7.8
diuresis
increased formation and excretion of urine
Average infant urine excretion/day
6-month-old infant produces about 500 mL of urine, an amount that increases gradually until about age 14
Pyridium (phenazopyridine)
local analgesic effect to the bladder mucosa to relieve burning; used when an infection is localized to the bladder
side effect of Pyridium (phenazopyridine)
Contains azo dye that turns the urine reddish orange
B&O suppository (belladonna and opium)
Has anticholinergic effects to relieve bladder spasms, and opium to relieve the pain in an acute situation
side effects of B&O suppository
controlled substance; has anticholinergic side effects
Ditropan (oxybutynin)
Produce anticholinergic effects, which relax the detrusor muscle; used to treat hyperreflexic bladders by suppressing the unwanted contractions that occur when the bladder has only a small volume of urine; also used to treat bladder spasmDetrol (tolterodine)s
side effects of Ditropan (oxybutynin)
Dry mouth, constipation, tachycardia, urinary hesitancy and retention, impotence, and other anticholinergic effects
Antibiotics sulfamethoxazole/trimethoprim
Treatment of urinary tract infections; needs to be excreted unchanged in the urinary tract; the combination reduces the possibility of resistant strains
side effects of sulfamethoxazole/trimethoprim
Hypersensitivity to sulfa
Minipress (prazosin)
Alpha-adrenergic receptor blockers relax the smooth muscle in the bladder neck, thus facilitating urinary flow through the prostatic urethra
Side effects of Minipress (prazosin)
Side effects related to blocking the adrenergic receptors could include dizziness, postural hypotension, urinary frequency, impotence, dry mouth, blurred vision
Cardura (doxazosin)
medication for urinary problems
Flomax (tamsulosin)
medication for urinary problems
Detrol (tolterodine)
medication for urinary problems
Pro-Banthine (propantheline)
medication for urinary problems
fecal impaction
a collection of puttylike or hardened feces in the rectum or sigmoid colon that prevents the passage of a normal stool and becomes harder as the colon continues to absorb water
diarrhea
rapid movement of fecal matter through the intestine, resulting in diminished absorption of water, nutrients, and electrolytes and producing abnormally frequent evacuation of watery stools
bowel incontinence
inability to voluntarily control the passage of feces and gas.
how much fiber/day should we consume?
25g
risks for colon cancer:
- Age over 50
- A family history of polyps or colorectal cancer
- A history of inflammatory bowel disease, such as ulcerative colitis or Crohn’s disease
- Living in an urban area
- A diet high in fat and low in fiber
bowel obstruction
Partial or complete blockage caused by a tumor, inflammation, strangulation, or adhesion that prevents the movement of chyme through the intestine. Bowel obstruction may initially present with constipation or diarrhea associated with abdominal distention, pain, and hyperactive bowel sounds in one quadrant.
Crohn’s disease
A chronic inflammatory bowel disease of unknown origin, usually affecting the ileum, the colon, or another part of the gastrointestinal tract. It is characterized by frequent attacks of diarrhea, severe abdominal pain, nausea, fever, chills, weakness, anorexia, and weight loss.
ulcerative colitis
A chronic, episodic, inflammatory disease of the large intestine and rectum. It is characterized by profuse watery diarrhea containing varying amounts of blood, mucus, and pus.
IBS
A chronic functional disorder of the bowel characterized by motor abnormalities within the gastrointestinal tract, causing variable symptoms including cramping, abdominal pain, constipation, or diarrhea. It does not result in permanent damage to the intestine. Affecting 15% of the population, it can often be managed with alternative therapies (Box 29-4).
cancer
Signs and symptoms that may indicate referral are a change in bowel habits and blood in the stool. Encourage clients to obtain routine screening tests for colon and rectal cancer.
infectious diarrhea
Sudden onset of watery diarrhea that can signal acute viral, bacterial, and protozoal infections. Most bacterial or viral diarrhea will resolve in 1 to 7 days. However, severe fluid and electrolyte disturbances can be life threatening, especially to the very young and very old.
paralytic ileus
direct handling of the bowel during abdominal surgery can temporarily stop peristalsis; when the absence of peristalsis persists beyond 3 days,
ostomy
procedure used to create a hole in the intestinal wall
ileostomy
surgical procedure involving the creation of an opening between the ileum and the abdominal wall
stoma
an opening between the abdominal wall and the intestine through which fecal material passes.
stress
occurs as a response to demands placed on one’s body and/or mind
GAS: alarm reaction
Immediately when the body encounters a stressor an alarm is initiated and the fight-or-flight response begins. The person’s resistance is decreased so ideally the body transitions to the next phase before disease or death occur
General Adaptation Syndrome
Body’s general response to stressors
GAS: resistance phase
the individual is still exposed to the stressor, but physiologic reserves are mobilized to increase the resistance to stress. This is the time of adaptation. It is during this stage that the factors that influence stress, such as attitude or coping abilities, will positively or negatively affect the resistance to the stressor. No physical signs or symptoms can be seen while an individual expends energy to adapt to a stressor, but the body will become strained over time.
GAS: Exhaustion phase
when all energy is expended, At the stage of exhaustion, it is common to become ill and even die if assistance from an outside source is not available (Fig. 8-2). This stage can often be reversed by external sources of adaptive energy, such as medication.
Three main systems in the physiologic response to stress:
nervous, immune, endocrine
Reticular Activating System (RAS)
which sends impulses contributing to alertness to the limbic system and to the cerebral cortex. When the RAS is stimulated, it increases its output of impulses, leading to wakefulness. Stress usually increases the degree of wakefulness and can lead to sleep disturbances.
coping
a person’s cognitive and behavioral efforts to manage specific external or internal stressors that seem to exceed available resources
emotion-focused coping
involves managing the emotions that an individual feels when a stressful event occurs. Examples of emotion-focused coping include discussion of feelings with a friend or taking a hot bath.
problem-focused coping
attempts to find solutions to resolve the problems causing the stress. For example, setting priorities or collecting information and seeking advice would be considered problem-focused coping.
synovium
the inner layer of the articular capsule surrounding a freely movable joint. It is loosely attached to the external fibrous capsule and secretes a thick fluid to lubricate the joint and absorb shock.
Most common type of joint:
synovial, or diarthrodial, joint
synarthrodial joints
immovable joints in the skull
amphiarthrodial joints
slightly movable joints; pelvis and ribs
proprioception
sensation pertaining to stimuli originating from within the body regarding spatial position and muscular activity, or to the sensory receptors that they activate; awareness of body position, posture, and movement
gait
the manner in which we walk
stance phase of gait
heel strike through the push-off action of the first foot. An abnormality in the stance phase is called an antalgic gait.
swing phase of gait
includes the action of the second foot from acceleration through deceleration. An abnormality in this phase is called a lurch.
