An adult patient is admitted with AIDS and oral Candida albicans manifested by several painful mouth ulcers. The nurse delegates oral care to the unlicensed assistive personnel (UAP) and discusses how to assist the patient.

Which instruction should the nurse give to the UAP?

The correct answer is choiceb. Identify the client using 2 client identifiers,c. Perform hand hygiene,e. Don gloves,f. Check the skin around the face, andg. Assess respiratory function.

Choice A rationale:

Determining if the client needs to go to the bathroom is not directly related to the immediate preparation for oxygen administration. However, it can be considered as part of overall patient comfort and care.

Choice B rationale:

Identifying the client using 2 client identifiers is crucial to ensure the correct patient is receiving the correct treatment, which is a standard safety protocol in healthcare settings.

Choice C rationale:

Performing hand hygiene is essential to prevent the spread of infection and maintain a sterile environment.

Choice D rationale:

Brushing the client’s teeth is not a necessary step before applying a simple face mask for oxygen administration. It is more related to general oral hygiene.

Choice E rationale:

Donning gloves is important to protect both the nurse and the patient from potential contamination and infection.

Choice F rationale:

Checking the skin around the face is important to ensure there are no existing sores or irritations that could be exacerbated by the mask.

Choice G rationale:

Assessing respiratory function is critical to determine the patient’s baseline respiratory status and to monitor the effectiveness of the oxygen therapy.

Choice A rationale:

Lactulose is a non-absorbable disaccharide that is metabolized by bacteria in the colon to produce lactic acid and acetic acid. These acids acidify the colon, which traps ammonia (NH3) in the colon and converts it to ammonium (NH4+). Ammonium is not absorbed by the colon and is excreted in the stool. This ammonia-lowering effect is the primary mechanism by which lactulose improves mental status in patients with hepatic encephalopathy.

Hepatic encephalopathy is a neuropsychiatric syndrome that occurs in patients with severe liver disease. It is caused by the buildup of ammonia in the blood, which can cross the blood-brain barrier and cause cerebral edema and impaired brain function.

The clinical manifestations of hepatic encephalopathy range from mild confusion and personality changes to coma. Improved mental status is a key therapeutic goal in the treatment of hepatic encephalopathy.

Studies have shown that lactulose can improve mental status in patients with hepatic encephalopathy. A meta-analysis of 11 randomized controlled trials found that lactulose was associated with a significant improvement in mental status compared to placebo.

The improvement in mental status is typically seen within 24 to 48 hours of starting lactulose therapy.

Choice B rationale:

Increased urine output is not a direct therapeutic effect of lactulose. Lactulose can cause diarrhea, which can lead to increased urine output due to fluid loss. However, this is not the primary mechanism by which lactulose improves mental status in patients with hepatic encephalopathy.

Choice C rationale:

Reduction in the number of liquid stools is a common side effect of lactulose. However, it is not a therapeutic goal in the treatment of hepatic encephalopathy. The goal of lactulose therapy is to improve mental status by lowering ammonia levels in the blood.

Choice D rationale:

Ability to ambulate independently is not a direct therapeutic effect of lactulose. Lactulose can improve mental status, which may indirectly lead to improved ambulation in some patients. However, this is not the primary mechanism by which lactulose works.
