Question 1 of 5
A client with liver cirrhosis is receiving lactulose for hepatic encephalopathy. Which finding indicates the medication is effective?
Correct Answer: B
Rationale: The correct answer is B: "The client's ammonia level decreases." In hepatic encephalopathy, elevated ammonia levels contribute to neurological symptoms. Lactulose works by promoting the excretion of ammonia in the stool, leading to decreased serum ammonia levels. Therefore, a decrease in ammonia levels indicates that lactulose is effectively reducing ammonia buildup, improving hepatic encephalopathy symptoms. Choices A, C, and D are incorrect because improvement in level of consciousness, bowel movements, or normalization of liver enzymes may not directly reflect the effectiveness of lactulose in reducing ammonia levels and improving hepatic encephalopathy.
Question 2 of 5
A client with a tracheostomy develops copious, thick secretions. What is the nurse's priority action?
Correct Answer: D
Rationale: The correct answer is to increase the humidity of the oxygen source. This action helps thin thick secretions, making them easier to clear from the tracheostomy tube. Increasing fluid intake (Choice A) can be beneficial in some cases but addressing humidity is more specific to managing thick secretions in a client with a tracheostomy. Tracheal suctioning (Choice B) should be done after attempting to thin the secretions with increased humidity. Administering a mucolytic agent (Choice C) is a possible intervention but typically comes after addressing humidity and before resorting to suctioning to avoid unnecessary invasiveness.
Question 3 of 5
A client with cirrhosis is receiving lactulose. What is the most important assessment for the nurse to monitor?
Correct Answer: D
Rationale: The correct answer is to monitor the client's level of consciousness. Lactulose is used to reduce ammonia levels in hepatic encephalopathy. Monitoring the level of consciousness helps assess the effectiveness of lactulose therapy in improving the client's condition. Monitoring ammonia levels (choice A) is important, but assessing the client's response to therapy through their level of consciousness is more crucial. Blood glucose levels (choice B) and potassium levels (choice C) are not directly related to lactulose therapy for cirrhosis and hepatic encephalopathy.
Question 4 of 5
A client receiving IV heparin reports abdominal pain and tarry stools. What is the nurse's priority action?
Correct Answer: A
Rationale: The correct answer is to prepare to administer protamine sulfate. Abdominal pain and tarry stools are indicative of gastrointestinal bleeding, a serious side effect of heparin therapy. Protamine sulfate is the antidote for heparin and is used to reverse its effects in cases of bleeding. Continuing the heparin infusion (Choice B) is not appropriate when the client is experiencing signs of bleeding. Monitoring vital signs and assessing abdominal pain (Choice C) is important but not the priority when immediate action is required to address potential bleeding. Administering morphine sulfate (Choice D) is not the priority in this situation; addressing the underlying cause of bleeding takes precedence.
Question 5 of 5
A client with diabetes mellitus is experiencing hyperglycemia. What laboratory value should the nurse monitor to evaluate long-term glucose control?
Correct Answer: B
Rationale: The correct answer is B: Glycosylated hemoglobin (A1C). Glycosylated hemoglobin reflects long-term glucose control over the past three months. Monitoring blood glucose levels provides information on the current glucose status and immediate control, but it does not give a comprehensive view of long-term control. Urine output and serum ketone levels are important indicators for other aspects of diabetes management, such as hydration status and ketone production during hyperglycemic episodes, but they do not directly reflect long-term glucose control.
