A nurse is caring for a client who is to maintain a fluid restriction of 1,200 mL/24 hr. How many mL of fluids can the client have over the next 20 hr if the client had a total fluid intake of 300 mL during the first 4 hr of the shift?

Choice A rationale
The vital signs presented in this choice are within the normal range. A blood pressure of 118/76 mm Hg is considered normal. A heart rate of 92/min is slightly elevated but still within the normal range (60-100 beats per minute). A temperature of 38.1° C (100.6° F) indicates a slight fever, which could be a response to an infection or inflammation. An oxygen saturation of 95% on room air is within the normal range (95%-100%).
Choice B rationale
The vital signs presented in this choice indicate that the patient may be experiencing a respiratory issue. A blood pressure of 126/84 mm Hg is slightly elevated but still within the acceptable range. A heart rate of 104/min is high, indicating that the heart is working harder than normal. A respiratory rate of 24/min is also high, suggesting that the patient may be having difficulty breathing. A temperature of 38.5 C (101.3* F) indicates a fever, which could be a response to an infection. An oxygen saturation of 92% on room air is below the normal range (95%-100%), suggesting that the patient is not getting enough oxygen. This is the vital sign that should be addressed first.

Choice A rationale
Sorbitol is a type of sugar alcohol used as a sweetener in many diet foods. It is also used in certain medications as a laxative to relieve constipation. However, it is not typically associated with liver failure and would not likely be questioned by the nurse in this context.
Choice B rationale
Lactulose is a type of sugar that is broken down in the large intestine into mild acids that draw water into the intestine, which then helps soften the stools. It is often used to treat constipation and is also used to reduce high blood ammonia levels in patients with liver disease. It would not typically be questioned by the nurse for a patient with chronic liver failure.
Choice C rationale
Neomycin is an antibiotic that is used to reduce the amount of ammonia produced by bacteria in the intestines. High levels of ammonia can cause hepatic encephalopathy, a serious complication of liver disease. Therefore, neomycin can be beneficial for patients with chronic liver failure and would not likely be questioned by the nurse.
Choice D rationale
Acetaminophen, also known as paracetamol, is a common over-the-counter medication used to relieve pain and reduce fever. However, high doses or long-term use of acetaminophen can cause liver damage. In fact, acetaminophen overdose is a common cause of acute liver failure. Therefore, the nurse should question an order for acetaminophen for a patient with chronic liver failure.
