Correct Answer is A

Explanation

Choice A reason:

The urea breath test is typically used to diagnose Helicobacter pylori (H. pylori) infection in the stomach. H. pylori can lead to gastritis and ulcers, which can interfere with nutrient absorption and contribute to imbalanced nutrition.

Choice B reason:

Impaired dentition related to gingivitis is not directly related to the need for a urea breath test. This diagnosis pertains to dental health, not gastric health.

Choice C reason:

Diarrhea related to Clostridium difficile infection is not directly related to the need for a urea

breath test. This diagnosis pertains to a bacterial infection in the colon, not H. pylori infection in the stomach.

Choice D reason:

Risk for impaired skin integrity related to peptic ulcers is also not directly related to the need for a urea breath test. This diagnosis pertains to potential skin breakdown due to ulcers, not the

assessment of H. pylori infection.

A. Keep the patient in a low Fowler's position when at rest. B. Connect the tube to continuous wall suction when not in use. C. Confirm placement of the tube prior to each medication administration. D. Have the patient sip cool water to stimulate saliva production.

Correct Answer is C

Explanation

Choice A reason:

Keeping the patient in a low Fowler's position may be helpful for some patients with dysphagia, but it is not a specific intervention related to NG tube care.

Choice B reason:

Connecting the tube to continuous wall suction when not in use is not a standard practice for NG tube care. Continuous suction can cause mucosal damage and discomfort for the patient.

Choice C reason:

Confirming the placement of the NG tube prior to each medication administration is a crucial safety measure. Incorrect placement can lead to serious complications.

Choice D reason:

Sipping cool water to stimulate saliva production may be beneficial for some patients with dysphagia, but it is not a specific intervention related to NG tube care. The focus should be on confirming the placement of the tube.
