Enemas questions with correct answersEnema Correct Answer-instillation of a solution into the rectum and
sigmoid colon. Primary reason for an enema is to promote defection by
stimulating peristalsis. The most common use for an enema is temporary
relief of constipation
Enema Correct Answer-The volume of fluid instilled breaks up the fecal
mass, stretches the rectal wall and initiates the defection reflex. Other
indications include removing impacted feces, emptying the bowel before
diagnostic tests or surgery and beginning a bowel program
Cleansing enemas Correct Answer-Cleansing enemas promote the
complete evacuation of feces from the colon. They act by stimulating the
peristalsis through the infusion of a large volume of solution or though
local irritation of the mucosa of the colon
Cleansing enemas Correct Answer-include tap water, normal saline,
soapsuds solution, and low volume hypertonic saline. Infants and
children receive only normal saline because they are at risk for fluid
imbalance
Tap water enemas Correct Answer-tap water is hypotonic and exerts an
osmotic pressure lower than fluid in the interstitial space. After infusion
into the colon, tap water escapes from the bowel lumen into interstitial
spaces. Do NOT repeat tap water enemas because water toxicity or
circulatory overload develops if the body absorbs large amounts of
water.
, Normal Saline enemas Correct Answer-physiologically normal saline is
the safest solution to use because it exerts the same osmotic pressure as
fluids in the interstitial spaces surrounding the bowel. The volume
infused saline stimulates peristalsis. giving saline enemas does not create
the danger of excess fluid absorption
Hypertonic solution enema Correct Answer-Infused into the bowel exert
osmotic pressure that pulls fluids out of interstitial spaces. The colon
fills with fluid and the resultant distention promotes defection. Pts
unable to tolerate large volumes of fluid benefit most from this type of
enema which is by design low volume. Contraindicated for pts who are
dehydrated and young infants
Soapsuds enema Correct Answer-you add soapsuds to tap water or
saline to create the effect of intestinal irritation to stimulate peristalsis.
Use only castile soap that comes in liquid form included in most
soapsuds enema kits. Use with caution in pregnant women and older
adults because they cause electrolyte imbalance or damage to the
intestinal mucosa
High and low enemas Correct Answer-High enemas cleanse the entire
colon. After enema is infused ask pt to turn from the left lateral to the
dorsal recumbent over to the right lateral position, it ensures that fluid
reaches the large intestine. A low enema cleanses only the rectum and
sigmoid colon
Oil retention enema Correct Answer-they lubricate the rectum and
colon. The feces absorb the oil and become softer and easier to pass. To
