Below are 5 non directional hypothesis. Restate each one as a directional hypothesis ( NURSING RESEARCH)
1.Tactile stimulation is associated with comparable physiologic arousal as verbal stimulation among infants with congenital heart disease.
2.The risk for hypoglycemia in term newborns is related to the infants birth weight.
3.The use of isotonic sodium chloride solution before endotraheal suctioning is related to oxygen deprivation.
4.Fluid balance is related to degree of success in weaning older adults from mechanical ventilation
5.Nurses administer the same amount of narcotic analgesics to male and female patients
1)Tactile stimulation
is associated with comparable physiologic arousal as verbal
stimulation among infants with congenital heart
disease.
Infants were systematically assigned to different sequences of the
various stimuli.Measures of arousal included heart rate,blood
pressure,respiration and activity level. Results indicated that the
use of touch conducive
to neural excitation (i.e.,intense,vigorous,extensive touching of
highly innervated body areas)produced higher heart rates and
systolic blood pressure as well as greater activity than did other
types of
tactile stimulation or soothing verbal stimulation.Girls appeared
more physiologically responsive to touch than boys and a subset of
infants showed evidence of distress
during more arousing stimulation.It has been indentified that
infants who received regular tactile stimulation not only had a
shorter hospital stay but these infants also had increased daily
weight gain.These infants also showed
improved coordinated movements,range of postures,along with hand
and face movement control.Infants were systematically assigned to
different sequence of the various stimuli.Measures of arousal
included heart rate,blood pressure,respiration and activity
level.Results indicated that the use of touch conductive
to neutral excitation produce higher heart rates and systolic blood
pressure as well as greater activity than did other types of
tactile stimulation.
2)The risk for
hypoglycemia in term newborns is related to the infants birth
weight.
The incidence of hypoglycemia is higher in babies with a birth
weight of less than 50th percentile for gestational age up to 15%
in smal for gestational age infants and in preterm babies varies
between 5 to 10%.Hypoglycemia is common following severe birth
asphyxia,hypothermia,septicemia and polycythemia.
Neonatal hypoglycemia was defined as a blood glucose level of less
than 2.6mmol/L measured after 2 hour of life.Blood glucose was
measured routinely for all SGA infants during the first 36hours of
life.
The level at which hypoglycemia becomes clinically important is not
well understood and the neurodevelopmental consequences of
asymptomatic hypoglycemiain term SGA infants are still
unknown.Glucose is the primary organic fuel for energy production
,especially for the brain.However,alternative substrates such as
ketone bodies,lactate,glycerol,B-Hrdroxybutarate and acetoacetate
play an important role in
glucose deprivation status.
3)The use of isotonic
sodium chloride solution before endotraheal suctioning is related
to oxygen deprivation.
According to the studies,isotonic sodium chloride instillation may
decrease oxygen saturation,increased intracranial pressure,arterial
blood pressure and cause cardiac dysrythmias,cardiac
arrest,respiratory arrest and nosocomial infection.
Insillation of isotonic chloride solution for endotracheal tube
suctioning is controversial.Neonates who had isotonic sodium
solution instilled experienced significantly greater oxygen
desaturation 1 and 2 minutes after suctioning than did patients who
did not.No occlusions of endotracheal tubes and no cases of
nosocomial pneumonia occurred in either group.
4)Fluid balance is
related to degree of success in weaning older adults from
mechanical ventilation.
A positive cumulative fluid balance is known to be associated with
increased mortality in critucally ill patients.Ther is a strong
biological plausibility to believe that the cumulative fluid
balance will have its impact on the respiratory outcome of
patients.A positive cummulative flid balance leads to increased
capillary leak,increase in extravascular
lung water and decrease in lung compliance and may result in
respiratory failure both during spontaneous braething trial(SBT)
and in the immediate post extubation period.However, extensive use
of diuretics in the study population and majority of patients
achieving negative fluid balance or euvolemia at the first SBT
questions the generalizability of the study results. Similar
independent association between positive fluid balance 24 h before
extubation and failure of extubation attempt was observed .
5)Nurses administer
the same amount of narcotic analgesics to male and female
patients.
Narcotic analgesic doses for the entire postoperative period were
converted to equinalgesic doses comparable to intramuscular
morphine.Male patients received significantly larger initial doses
than female patients.There was no gender differences in the total
postoperative narcotic analgesics than ethnic minority patients.The
gender differences provides modest external validation for prior
experimental results.The ethnic differences suggests that
irrelevent cues may be used in nurses medication decisions.
Patient gender and race predict the amount of analgesic given to
patients in a variety of clinical settings.These findings suggest
that, for pain as well as for other medical conditions,7–11 women
and minority patients are treated less aggressively. Such findings
raise concerns that decisions about pain management may be
influenced by patient characteristics unrelated to clinical
condition and point to possible treatment biases. It was predicted
that patients presented as female and as black would receive lower
doses of narcotic analgesics than patients described as male and as
white.
There is a statistically significant correlation between the gender
of the patient and the quatity of analgesia administered.
