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?
Pearson’s correlation coefficient (r)
Independent samples t-test

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?

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:
there is a moderate relationship between patient incivility and nursing burn-out.
there is no relationship between patient incivility and nursing burn-out.
there is a weak 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.
