A nurse is reinforcing teaching with a client about the oliguric phase of acute kidney injury. Which of the following information should the nurse include in the teaching?

The oliguric phase lasts for 2 days.

The client's urine output is less than 400 mL per 24 hours.

The oliguric phase begins within 1 month of the injury.

The client's BUN and creatinine decreases during this phase.

Answer and Explanation

The Correct Answer is B

A.   The oliguric phase of AKI typically lasts longer than 2 days. It can extend from several days to weeks, depending on the underlying cause and the response to treatment.
B.   During the oliguric phase of AKI, urine output is significantly reduced. Typically, urine output is less than 400 mL per day, but it can vary widely based on the severity of kidney injury and individual factors.
C.   The oliguric phase of AKI usually begins within a few days to a week after the initial injury. It is characterized by a sudden decrease in urine output and may be accompanied by electrolyte imbalances and fluid overload.
D.   During the oliguric phase of AKI, there is typically a buildup of waste products such as blood urea nitrogen (BUN) and creatinine in the blood. These levels rise because the kidneys are unable to effectively filter and excrete waste products. Therefore, BUN and creatinine levels usually increase during the oliguric phase.

Correct Answer is A

Explanation

A. The oral mucosa, especially the lips and tongue, is a reliable indicator of central cyanosis. Cyanosis is evident as bluish discoloration in these areas due to the presence of deoxygenated hemoglobin.
B. Cyanosis is less reliably visible on the eyelids compared to the lips and oral mucosa. Skin over the eyelids is typically thinner, but detection of cyanosis here can be more challenging due to variations in skin pigmentation and thickness.
C. Similar to the eyelids, cyanosis may be less evident on the ear lobes compared to the lips and oral mucosa. Ear lobes are less vascular and may not consistently show cyanosis unless the condition is severe.
D. The tip of the nose is another area where cyanosis can be detected, although it is less reliable than the lips and oral mucosa. Like the eyelids and ear lobes, the detection of cyanosis here can vary depending on individual skin characteristics.

A. "Go to the emergency room and your provider will meet you there." B. "What else have you been eating?" C. "Come to the office and we will check things out." D. "This is expected because of the way iron is broken down during digestion."

Correct Answer is D

Explanation

A. There is no indication of an emergency based on black stools alone without other concerning symptoms such as severe abdominal pain, cramping, or signs of gastrointestinal bleeding.
B. While gathering more information about the client's diet may be helpful in some cases, it does not address the specific concern about the black stools related to iron supplementation.
C. Unless there are other concerning symptoms, such as gastrointestinal bleeding or significant discomfort, this situation does not typically warrant an immediate visit to the office. It can be managed with reassurance and education over the phone.
D. Iron supplements commonly cause stools to turn black due to the way iron is metabolized in the digestive system. This change in stool color is known as "iron-induced blackening." It occurs because iron supplements contain iron salts that undergo chemical reactions in the gastrointestinal tract, resulting in the production of iron sulfide compounds that impart a black color to the stool.
