,Which information is most accurate for the nurse to use when calculating safe
drug dosages for a child?
A. Age.
B. Height.
C. Weight.
D. Body surface area. - CORRECT ANSWER - D. Body surface area.
RATIONALE
The most accurate method of calculating pediatric doses is based on a child's body
surface area (BSA). Drug calculations are not consistently precise when made on
the basis of a child's age since children vary widely in size and maturity for
chronologic age. Although the calculation of a child's BSA utilizes a child's height
and weight, height and weight alone do not correlate with the distribution or
metabolism of a drug due to the variance in each child's growth and development.
To avoid a false positive result for fecal occult blood in a stool specimen, the nurse
should instruct the client to avoid ingestion of which substances prior to collecting
a sample? (Select all that apply.)
Fish.
,Beef.
Vitamin C tablets.
Turkey.
Ibuprofen.
Coffee. - CORRECT ANSWER - Beef.
Vitamin C tablets.
Ibuprofen
RATIONALE
The fecal occult blood test, or guaiac test, measures microscopic amounts of
blood in the feces. False positive results can occur from food products such as
beef and other red meats, green vegetables, vitamin C supplements, aspirin, and
nonsteroidal antiinflammatory medications, including ibuprofen.
In which order should the nurse implement these actions when withdrawing a
solution from an ampule? (Arrange from first on top to last on the bottom.) -
CORRECT ANSWER - 1.Flick the stem several times with a finger.
2.Wrap the neck with a protective device.
3.Break the neck by pressing thumbs outward.
4.Stabilize ampule on a firm surface.
5.Withdraw the solution using a filter needle.
, RATIONALE
Flicking the stem ensures all medication is in the bottom of the ampule. Wrapping
the neck with a protective device (such as a small gauze pad or alcohol prep pad)
protects fingers from trauma as the glass tip is broken off. Snapping the neck of
the ampule quickly and outwards minimizes the nurse's risk of injury from
shattering glass. Stabilizing the ampule assists in maintaining sterility as the
needle is placed to withdraw the solution. Withdrawing the solution with a filter
needle protects against aspirating microscopic glass into the syringe.
Which action by the nurse-manager demonstrates an effective leadership style?
A. Directs a staff nurse to modify communication skills.
B. Implements behavior changes through the annual evaluation process.
C. Uses the group process to determine behaviors that distress the staff.
D. Fosters positive behavior changes in staff members. - CORRECT ANSWER - D.
Fosters positive behavior changes in staff members.
Democratic leadership styles allow group members to participate in change, and
to effectively lead members in the change process, positive behavior changes in
staff members should be fostered and supported.
What clinical problem is suitable for research utilization in nursing?
