In an effort to decrease the rate of urinary tract infections, which of the following should the nurse manager teach the nursing staff? (Select all that apply)

Choice A rationale
Potassium levels are not directly affected by lactulose. While cirrhosis can lead to imbalances in electrolytes, including potassium, lactulose is not used to manage potassium levels in the bloodstream.

Choice B rationale
Ammonia is produced by the breakdown of proteins in the intestines and is normally processed by the liver. In cirrhosis, the liver's ability to convert ammonia to urea is impaired, leading to increased levels in the blood. Lactulose helps reduce blood ammonia levels by converting it into ammonium, which is then excreted.

Choice C rationale
Bicarbonate levels are related to the body's pH balance and are not the target of lactulose treatment. Cirrhosis does not typically result in bicarbonate imbalances that would be treated with lactulose.

Choice D rationale
Glucose levels are managed by insulin and other metabolic processes, not lactulose. While cirrhosis can affect overall metabolism, lactulose does not have a direct effect on blood glucose levels.

Choice A rationale
Jaundice of the sclera is indicative of hyperbilirubinemia, which can occur in various liver diseases but is not specifically associated with Grey Turner's sign or pancreatitis.

Choice B rationale
Bluish discoloration of the periumbilical area, known as Cullen's sign, is another indicator of severe pancreatitis but is distinct from Grey Turner's sign, which specifically refers to the flank area.

Choice C rationale
Left abdominal pain that occurs with movement may be a symptom experienced by patients with pancreatitis, but it is not referred to as Grey Turner's sign, which is a physical finding rather than a symptom.

Choice D rationale
Grey Turner's sign is characterized by bluish discoloration of the flank area. It is a sign of retroperitoneal hemorrhage, which can occur in severe cases of pancreatitis due to the spread of pancreatic enzymes to surrounding tissues, leading to localized bleeding.
