Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

8. Body temperature may be defined as the degree
of heat maintained by the body. It is the balance
between heat production & heat loss of the body
Normal body temperature using oral 370 Celsius
or 98.6 0 F.
8
9. Mechanism of temperature regulation
Thermogenesis – a chemical regulation by the
production of heat
Thermolysis – a physical regulation by loss of heat
our internal boady temperature is regulated by a part of
our brain called the hypothalamus. The hypothalamus
checks our current temperature and compares it with
the normal temperature of about 37 Degree Celsius. If
our temp. is too low the hypothalamus
Makes sure that the boady generates and maintain heat.
Temp. is too high heat is given off or sweat is produced
to cool the skin.
10. 1. Core Temperature

15. Normal body temperature is 370 C or 98.6 0F (range
is 36-38 0c (96.8 – 98.6 0F))
Body temperature may be abnormal due to fever
(high temperature) or hypothermia (low
temperature).
Pyrexia, fever: a body temperature above the
normal ranges 38 0c – 410 c (100.4 –105.8 F)
Hyper pyrexia: a very high fever, such as 410 C > 42
0c leads to death.
Hypothermia: – body temperature between 34 0c –
35 0c, < 34 0c is death

19. Types of fever
Onset or invasion : onset or invasion of fever is the period when
the
body temperature is raising and it may be a sudden or gradual
process.
Fastigium or stadium : fastigium or stadium of fever is the
period when the body temperature has reached its maximum
and remainsfairly constant at a high level.
Defervescence or decline : defervescence or decline of the fever
is period when the elevated temperature is returning to normal.
The fever may subside suddenly (decline by crisis) or gradually
(decline by lysis)
Crisis : crisis is a sudden return to normal temperature from a
very high temperature within a few hours or days
20. •True crises : the temperature falls suddenly within few
hours and touches normal, accompanied by a marked
improvement in the clients conditions
•False crises : the sudden falls in temperature not
accompanied by a improvement in the clients
conditions is called false crises.
•Lysis : the temperature falls in zig-zag manner for 2 or
3 days or a week before reaching normal, during which
time the other symptom also gradually disappear
•Constant fever or continuous fever : constant fever
or continuous fever is one in which the temperature
varies not more than two degree between morning and
evening and it does not reach normal for a period of
days or week
21. Remittent fever : remitting fever is a fever
characterized by variation of more than two degree
between morning and evening but does not reach
normal
Intermittent or quotidian fever : the temperature
rises from normal or sub normal to high fever and back
at regular interval. Usually the temperature is higher in
the evening then in the morning
Inverse fever: the highest range of temperature is
recorded in the morning hours and the lowest in the
evening which is contrary to that found in the normal
course of fever
hectic or swinging fever : when the difference between
the high and low points is very great, the fever is called
hectic fever.
22. Relapsing fever: relapsing fever is one in which there
are brief febrile period followed by one or more days
of normal temperature
Irregular fever: when the fever is entirely irregular
in its course, it cannot be classified under any one of
the fever described above is called irregular fever
Rigor : rigor is a sudden severe attack of shivering in
which the body temperature rises rapidly to a stage of
hyperpyrexia as seen in malaria
23. Nursing care in fever
1. Regulation of body temperature
2. Meeting the nutritional need
3. Maintenance of personal hygiene
4. Providing rest and sleep
5. Maintenance of personal hygiene
6. Safety factor
7. Observation of the client
24. Nursing care in rigor
1. Stage one or cold stage
2. Stage two or hot stage
3. Stage three or stage of sweating
26. Pulse is a wave of blood created by the
contraction of left ventricle.
pulse reflects the heart beat
Stroke volume and the compliance of
arterial wall are the two important factors
influencing pulse rate.
Pulse rate is regulated by autonomic
nervous system.
26
27. Peripheral Pulse: is a pulse located in the
periphery of the body e.g. in the foot, and or neck
Apical Pulse (central pulse): it is located at the
apex of the heart
The PR is expressed in beats/ minute (BPM)
The difference between peripheral and apical pulse
is called pulse deficit, and it is usually zero.
27
28. Pulse is assessedfor
28
• rate (60-100bpm),
• rhythm (regularity orirregularity),
• Volume,
• elasticity of arterialwall.
The pulse is commonly assessed by palpation
(feeling) and auscultation (hearing using a
stethoscope).
29. Age
The average pulse rate of an infant ranges from
100 to 160BPM
The normal range of the pulse in an adult is 60
to 100 BPM
Sex: Sex: after puberty the average males
PRis slightly lower than female
30
30. Autonomic Nervous systemactivity
30
Stimulation of the parasympathetic nervous
system results in decrease in the PR
Stimulation of sympathetic nervous system
results in an increased pulse rate
Sympathetic nervous system activation occurs
on response to a variety of stimuli including
▪ Pain ,anxiety ,Exercise, Fever
▪ Ingestion of caffeinated beverages
▪ Change in intravascular volume
31. Exercise: PRincrease with exercise Fever:
increases PRin response to the lowered
B/P that results from peripheral
vasodilatation – increased metabolic rate
Heat: increase PRas acompensatory
mechanism
Stress: increases the sympathetic nerve
stimulation
31
32. * Position changes:
a sitting or standing position blood usually
pools in dependent vessels of the venous
system. B/c of decrease in the venous blood
return to heart and subsequent decrease in BP
increases heart rate.
32
33. * Medication
33
o Cardiac medication such as digoxin decrease heart
rate
o Medications that decrease intravascular volume
such as diuretics may increase pulse rate
o Atropine inhibits impulses to the heart from the
parasympathetic nervous system, causing increased
pulse rate
o Propranolol blocks sympathetic nervous system
action resulting in decreased heart rate sites used
for measuring pulse rate
34. Carotid: at the side of the neck below tube of the
ear (where the carotid artery runs between the
trachea and the sternocleidomastoid muscle)
Temporal: the pulse is taken at temporalbone
area.
Apical: at the apex of the heart: routinely used
for infant and children < 3 yrs
In adults – Left mid-clavicular line under the
4th, 5th, 6th intercostalspace
34
35. Brachial: at the inner aspect of the biceps muscle
of the arm or medially in the antecubital space
(elbow crease)
Radial: on the thumb side of the inner aspect of
the wrist – readily available and routinely used
Femoral: along the inguinal ligament. Used or
infants and children
Popiliteal: behind the knee. By flexing the knee
slightly
Posterior tibial: on the medial surface of the
ankle

system
43
44. If the pulse is regular, measure (count) for
30 seconds and multiply by 2
If it is irregular count for 1 full minute.
Each heart beat consists of two sounds
s1 - is caused by closure of the mitral and
tricuspid
valves separating the atria from the ventricles
S2 – is caused by the closure of the plutonic
and aortic values
The sounds are often described as a muffled
“lub – bub”
44
46. Respiration rate (RR):-Respiration is the
act of breathing and includes the intake of
oxygen and removal of carbon-dioxide.
Ventilation is also another word, which
refers
to movement of air in and out of the lung.
Hyperventilation: - is a very deep, rapid
respiration.
Hypoventilation: -is a very shallow
respiration.
46
47. 1. Costal (thoracic)
Observed by the movement of the chest up
ward and down ward.
Commonly used for adults
2. Diaphragmatic
(abdominal)
Involves the contraction and relaxation of the
diaphragm, observed by the movement of
abdomen.
Commonly used for children.
47
48. Age Normal growth from infancy to adult
hood results in a larger lung capacity.As lung
capacity increases, lower respiratory rates
are sufficient to exchange
Medications Narcotics decrease respiratory
rate
& depth
Stress or strong emotions increases the rate
& depth of respirations.
Exercise increases the rate & depthof
respirations
48
49. Altitude The rate & depth of respirations at
higher elevations (altitude) increase to
improve the supply of oxygen available to
the body tissues
Gender Men may have a lower
respirations rate than women because
men normally have a larger rung capacity
than women
Fever increases respiratoryrate
50
50. o The client should be at
rest
50
o Assessed by watching the movement of the
chest or abdomen.
o Rate,
o rhythm,
o depth and
ospecial characteristics of respiration
are assessed
51. Rate:
Is described in rate per minute (RPM)
Healthy adult RR= 15- 20/ min. is measured
for full minute, if regular for 30 seconds.
As the age decreases the respiratory rate
increases.
Eupnea- normal breathing rate and depth
Bradypnea- slowrespiration
Tachypnea - fastbreathing
Apnea - temporary cessation of breathing

Age Average Range/Min
New born 30-80
Early childhood 20-40
Late childhood 15-25
Adulthood-male 14-18
Female 16-20
53. Rhythm:
is the regularity of expiration and
inspiration Normal breathing is automatic &
effortless.
Depth:
described as normal, deep or shallow.
Deep: a large volume of air inhaled &
exhaled, inflates most of the lungs.
Shallow: exchange of a small volume of air
minimal use of lung tissue.
53
54. It is the force exerted by the blood against
the walls of the arteries in which it is flowing.
It is expressedin terms of millimeters of
mercury (mm ofHg).
54
55. Systolic pressure is the maximum of the
pressure against the wall of the vessel
following ventricularcontraction.
Diastolic pressure is the minimum
pressure of the blood against the walls of
the vessels following closure of aortic
valve (ventricular relaxation).
55
56. BP is measured by using an instrument
called Bp cuff (sphygmomanometer) &
stethoscope and
the average normal value is 120/80mmHg

adults.
brachial artery and popliteal artery are most
commonly used.
It is measured by securing the Bp cuff to the
upper arm & thigh placing the stethoscope
on brachial artery in the antecubital space &
popliteal artery at the back of the knee.
Pulse pressure: is the difference between

Fore-arm using radialartery
Legusing posterior tibial or dorsal pedis

59. Apersistently high Bp, measured for greater
than three times is called hypertension & that
persistently less than normal range is called
hypotension.
Because of many factors influencing Bp a
single
measurement is not necessarily significant to
confirm hypertension.
When the cause of hypertension is known it is
called secondary hypertension and when the
cause is unknown is calledprimary/essential
hypertension. 60
60. Purpose
To obtain base line measure of arterial
blood pressure for subsequentevaluation
To determine the clients homodynamic
status
To identify and monitor changes in blood
pressure.

64. Explain the procedure to the patient &
remove
any light cloth from patient’s arm
Make sure that the client has not smoked or
ingested caffeine, within 30 minutes prior to
measurement.
Position the patient on lying, sitting or
standing position, but always ensure that
the sphygmomanometer is at the level of the
heart with the arm supported & the palm
facing upwards.
64
65. apply cuff snugly/securely around the arm ,
2.5cm above the antecubital space/fossa, at
the level of the heart (for every cm the cuff
sites above or below the level of the heart
the BP varies by 0.8mmHg)
Palpate the radial pulse and inflate the cuff
until the radial pulse can no longer be felt,
this provides an estimation of systolic
pressure.
Inflate cuff 30mmHg higher than estimated
systolic pressure.
65
66. palpate the brachial artery & place the bell of
the stethoscope over the site & the ear
pieces on ear, apply enough pressure to
keep the stethoscope in place (the bell of the
stethoscope is designed to amplify/intensify
low frequency sounds)
Deflate the cuff 2-4mmHg per second.
The first pulse heard is the systolic reading,
continue to deflate until there is a change in
tone to a muffled beat, this is the diastolic
reading.
66
67. Deflate & remove cuff roll neatly and
replace.
Record the systolic and diastolic pressure
on vital singsheet and compare the
present reading with previous reading.
report or treat any change
Clear ear pieces and bell of the
stethoscope with antiseptic swab and
return all equipments.
