Nursing Elites

1. A patient with an anxiety disorder is prescribed alprazolam. What is the primary action of this medication?

• A. Increase energy levels
• B. Induce sedation
• C. Elevate mood
• D. Reduce anxiety

Correct answer: D

Rationale: Alprazolam is a benzodiazepine that primarily works by reducing anxiety. It achieves this by enhancing the inhibitory effects of the neurotransmitter GABA in the brain, which leads to a calming effect on the individual. Therefore, the primary action of alprazolam is to decrease anxiety levels rather than increase energy, induce sedation, or elevate mood.

2. A client with a history of chronic heart failure is experiencing severe shortness of breath and has pink, frothy sputum. Which action should the nurse take first?

• A. Administer morphine sulfate.
• B. Place the client in a high Fowler's position.
• C. Initiate continuous ECG monitoring.
• D. Prepare the client for intubation.

Correct answer: B

Rationale: In a client with chronic heart failure experiencing severe shortness of breath and pink, frothy sputum, the priority action for the nurse is to place the client in a high Fowler's position. This position helps improve lung expansion, ease breathing, and enhance oxygenation by reducing venous return and decreasing preload on the heart. It is crucial to address the client's respiratory distress promptly before considering other interventions. Administering morphine sulfate (choice A) may be appropriate later to relieve anxiety and reduce the work of breathing, but positioning is the priority. Continuous ECG monitoring (choice C) and preparing for intubation (choice D) are important but secondary to addressing the respiratory distress and optimizing oxygenation.

3. A client with cirrhosis of the liver is being cared for by the healthcare team. Which clinical manifestation indicates that the client has developed hepatic encephalopathy?

• A. Asterixis.
• B. Jaundice.
• C. Ascites.
• D. Splenomegaly.

Correct answer: A

Rationale: Asterixis, also known as flapping tremor, is a characteristic sign of hepatic encephalopathy, a severe complication of liver cirrhosis. Hepatic encephalopathy results from the liver's inability to detoxify substances in the body, leading to neurologic manifestations such as changes in mental status, confusion, and asterixis.

4. A 28-year-old woman at 34 weeks of gestation presents with elevated liver enzymes and pruritus. Labs reveal total bilirubin to be 4.2 mg/dL, AST 480 U/L, ALT 640 U/L, and alkaline phosphatase 232 U/L. Viral hepatitis serologies and ANA are negative. On physical examination, she is jaundiced, but has a normal blood pressure, no edema, and a soft abdomen. The fetus is in no distress. Which of the following is true?

• A. The baby should be delivered immediately
• B. Symptoms will resolve promptly after delivery
• C. There is little risk of recurrence with subsequent pregnancies
• D. The mother should be screened for long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency

Correct answer: B

Rationale: The patient's presentation is consistent with intrahepatic cholestasis of pregnancy (ICP), a condition characterized by elevated liver enzymes, pruritus, and jaundice in the absence of other liver disease causes. ICP typically resolves promptly after delivery. Immediate delivery is indicated only for fetal distress, not maternal symptoms. ICP does have a significant risk of recurrence in subsequent pregnancies. Treatment options for ICP include cholestyramine and ursodeoxycholic acid. Screening for long-chain 3-hydroxyacyl-CoA dehydrogenase (LCHAD) deficiency is not indicated in this context as it is associated with acute fatty liver of pregnancy and HELLP syndrome, not ICP.

5. A client with liver cirrhosis is prescribed lactulose. What is the purpose of this medication?

• A. To lower blood sugar levels
• B. To reduce ammonia levels
• C. To treat liver inflammation
• D. To improve bile flow

Correct answer: B

Rationale: Lactulose is prescribed to reduce ammonia levels in clients with liver cirrhosis. Elevated ammonia levels can lead to hepatic encephalopathy, a serious complication of liver cirrhosis. Lactulose works by acidifying the colon, which in turn traps ammonia in the colon and helps its elimination from the body through stool, thereby reducing the risk of hepatic encephalopathy. Choice A is incorrect because lactulose does not lower blood sugar levels. Choice C is incorrect as lactulose is not used to treat liver inflammation. Choice D is incorrect as lactulose does not improve bile flow.
