NURS 5366 CERTIFICATION EVALUATION
SCRIPT FULL SOLUTION GRADED A+
●● A nurse in a cardiovascular ICU developed an intervention that she
believes can reduce patient time on the ventilator post-operatively. She
recruits study participants from the offices of cardiovascular surgeons.
She randomizes the participants to two groups, a treatment group and a
control group. She provides a novel teaching intervention along with a
spirometer to each participant in the treatment group one week prior to
their surgery. Participants in the control group received customary care.
After each participant's surgery, the researcher records the number of
hours that they are on the ventilator post-operatively. Which statistical
test should she select to determine the effects of her intervention on time
spent on ventilator post-operatively?
Answer: Independent samples t-test
●● A nurse is reading a journal article on the effects of patient incivility
on nursing burn-out. The results of the study were r = 0.50, p = .04 (with
alpha set at .05). The nurse correctly summarizes that:
Answer: there is a moderate relationship between patient incivility and
nursing burn-out.
●● A pediatric nurse is interested in research on a new medication used
to treat seizures in children. She reviews a study of the new drug where
researchers randomized 50 children to receive either the new seizure
drug (treatment group) or Phenobarbital (control group). The researchers
, monitored the number of seizures in both groups for three months. They
reported that the treatment group had fewer seizures (t = 2.25, p = .045)
(with alpha set at .05). The nurse correctly determines that children who
received the new drug had significantly fewer seizures than those who
received Phenobarbital.
Answer: True
●● A researcher wants to examine the relationship between post-partum
depression and maternal age. She recruits 50 women who have given
birth within the last 3 months from the WIC (Women, Infants, &
Children Food and Nutrition) office. She collects demographic
information from each woman (including age, race/ethnicity, and
educational achievement) as well as administering a post-partum
depression survey. Which of the following statistical tests should she
select for her analysis?
Answer: Pearson's correlation coefficient (r)
●● A group of researchers studied functional impairment scores in a
group of 10 patients before and after a new rehabilitation intervention.
The researchers set the alpha at 0.05 which meant that the critical t value
would be 2.26 (9 df). Data analysis showed t(9)=2.84, p=.045. What do
these results mean?
Answer: There was a statistically significant difference between the
functional impairment scores obtained before and after the intervention.
