Question 1

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 theintervention (of a walking program alternating with
resistance training). After a month of thetreatment, all of theparticipants are weighed
again. Which statistical test should theresearcher select to determine theeffect of his
intervention on weight loss?

Question 2

A nurse in a cardiovascular ICU developed an intervention that she believes can reduce
patient time on theventilator post-operatively. She recruits study participants from
theoffices of cardiovascular surgeons. She randomizes theparticipants to two groups, a
treatment group and a control group. She provides a novel teaching intervention along
with a spirometer to each participant in thetreatment group one week prior to their
surgery. Participants in thecontrol group received customary care. After each
participant’s surgery, theresearcher records thenumber of hours that they are on
, theventilator post-operatively. Which statistical test should she select to determine
theeffects of her intervention on time spent on ventilator post-operatively?

Question 3
pts
A nurse is reading a journal article on theeffects of patient incivility on nursing burn-out.
theresults of thestudy were r = 0.50, p = .04 (with alpha set at .05). thenurse 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.

Question 4
pts
A pediatric nurse is interested in research on a new medication used to treat seizures in
children. She reviews a study of thenew drug where researchers randomized 50
children to receive either thenew seizure drug (treatment group) or Phenobarbital
(control group). theresearchers monitored thenumber of seizures in both groups for
three months. They reported that thetreatment group had fewer seizures (t = 2.25, p
= .045) (with alpha set at .05). thenurse correctly determines that children who received
thenew drug had significantly fewer seizures than those who received Phenobarbital.
