The nurse is caring for a patient with chronic liver failure.
Which medication order should the nurse querry
Sorbitol.
Lactulose.
Neomycin.
Acetaminophen.
The Correct Answer is D
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.

Correct Answer is D
Explanation
Choice A rationale
Informing the charge nurse is an important step, but it is not the immediate action. The nurse should first assess the situation before escalating it.
Choice B rationale
Applying a dressing under the client’s nose might help manage the drainage, but it does not address the underlying issue. The drainage could be cerebrospinal fluid (CSF), which is a serious condition that needs immediate attention.
Choice C rationale
Checking the client’s temperature is a general assessment and does not directly relate to the symptom of clear nasal drainage.
Choice D rationale
Testing the drainage for glucose is the correct action. Clear nasal drainage after a basal skull fracture could be a sign of a cerebrospinal fluid (CSF) leak. CSF contains glucose, so testing the drainage for glucose can help confirm if it’s CSF34.
Correct Answer is A
Explanation
Choice A rationale
Epinephrine is the first-line treatment for anaphylactic shock. It works by constricting blood vessels to increase blood pressure, relaxing smooth muscles in the lungs to reduce wheezing and improve breathing, stimulating the heart, and reducing hives and swelling around the face and lips.
Choice B rationale
Dexamethasone is a corticosteroid that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by reducing inflammation.
Choice C rationale
0.9% Normal Saline is a type of intravenous fluid that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by increasing fluid volume in the body to help maintain blood pressure.
Choice D rationale
Dobutamine is a medication that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by stimulating the heart muscle to increase cardiac output, which can help maintain blood pressure.
