N6 Feeding Tube Placement in Peds

Methods of Tube Placement
From the NUrsing Center
1.
To minimize the risk of aspiration, most clinicians prefer to position an enteral feeding tube so that feedings are administered into
a. the proximal portion of the stomach.
b. the first or second portion of the duodenum.
c. the duodenum beyond the ligament of Treitz.
2.
The risk of malabsorption increases when a complex formula is administered through an enteral tube with the tip placed in the
a. esophagus.
b. stomach.
c. duodenum.
3.
In children whose level of consciousness is decreased, delivering an enteral feeding to the stomach increases the risk of
a. aspiration.
b. diarrhea.
c. malabsorption.
4.
Theoretically, the best method of determining enteral tube placement is
a. enzyme measurement.
b. radiography.
c. tube insertion length.
5.
An infant's gastric pH typically changes to adult levels at the age of
a. 3 to 6 weeks.
b. 2 to 3 months.
c. 3 to 4 months.
6.
In a study by Metheny et al. (1994), small bowel aspirates were found to be
a. cloudy.
b. yellow.
c. tan.
7.
This study tested enteral tube placement in the intestines by confirming a higher concentration of which enzyme in the aspirate than in aspirates of tubes with gastric placement?
a. trypsin
b. rennin
c. pepsin
8.
The primary purpose of the author's study of methods of determining feeding tube placement in children was to
a. determine a cost-effective way to rule out lung placement of enteral feeding tubes.
b. replicate findings of previous studies of methods distinguishing stomach and intestinal placement.
c. discourage the use of nonreliable methods of confirming feeding tube placement in children.
9.
To correlate assessment findings with actual tube placement, the author incorporated which of the following into the study design?
a. using two distinct methods of enzyme measurement for each aspirated sample
b. collecting aspirate only if no tube-administered medications were given within the previous 2 hours
c. aspirating samples within 30 minutes of chest or abdominal radiography
10.
During the author's study, what percentage of the feeding tubes aspirated for the study had been incorrectly placed?
a. 5%
b. 13%
c. 21%
11.
The author's findings corroborated that the factor having the most influence on pepsin concentrates in the aspirates was
a. the method of enzyme testing.
b. how recently the child was fed.
c. the age of the child.
12.
Of the 56 aspirates studied, the two intestinal aspirates that did not meet the usual color criteria for intestinal contents appeared to be
a. partially digested blood.
b. clabbered formula.
c. medication residue.
13.
A green aspirate with pH of 4.5 indicates
a. stomach placement.
b. intestinal placement.
c. the need for radiography.
14.
A negative result of either pH, color, or enzyme testing for gastric placement
a. is a good indicator of intestinal placement.
b. confirms intestinal placement.
c. indicates the need for radiography.
15.
The author concludes that the most practical and low-cost method for testing feeding tube placement in a variety of settings is
a. enzyme measurement.
b. tube insertion length.
c. testing for pH and color.
