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
Taking two tablets every 15 minutes is not the recommended dosing for nitroglycerin. Overdosing can lead to hypotension and other side effects.
Choice B rationale
While the client should take the nitroglycerin sublingually, taking one tablet every 15 minutes up to 5 times is not the recommended dosing. This could lead to an overdose.
Choice C rationale
Nitroglycerin should be taken sublingually, not orally, for rapid absorption. Taking one tablet orally every hour up to 5 times is not the recommended dosing.
Choice D rationale
This is the correct dosing for nitroglycerin. If chest pain persists after the third dose, the client should seek immediate medical attention.
Correct Answer is B
Explanation
Choice A rationale
Changing the ostomy pouch daily is not necessary and can lead to skin irritation. The pouch should be changed every 2-4 days or as directed by the healthcare provider.
Choice B rationale
The ostomy pouch should be emptied when it is 1/3 to 1/2 full to prevent leakage and skin irritation.
Choice C rationale
Trimming the opening of the ostomy seal to be 1/2 in. wider than the stoma is incorrect. The opening should be just slightly larger than the stoma to prevent skin irritation.
Choice D rationale
Applying lotion to the peristomal skin when changing the ostomy pouch is not recommended as it can interfere with the adhesion of the pouch.
