Q: A Family Nurse Practitioner believes that he has developed an intervention that can accelerate
weight loss in adults with Type II diabetes when administered with a healthy diet. He recruits 25
participants from a local church. He obtains each participant's weight prior to beginning the
intervention (of a walking program alternating with resistance training). After a month of the
treatment, all of the participants are weighed again. Which statistical test should the researcher
select to determine the effect of his intervention on weight loss?
ANSWER ✔✔ Paired t-test
Q: 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
Q: 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:

Q: 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
