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: Rationale: Lactulose is prescribed for liver cirrhosis to reduce ammonia levels. It works by promoting the excretion of ammonia in the stool, preventing its accumulation in the bloodstream. This helps prevent hepatic encephalopathy, a serious complication of cirrhosis. Other choices are incorrect because lactulose does not directly affect blood sugar levels, liver inflammation, or bile flow in the context of liver cirrhosis.

The client is receiving intravenous (IV) morphine for pain control. Which assessment finding requires the most immediate intervention?
- A. Drowsiness.
- B. Itching.
- C. Nausea.
- D. Respiratory rate of 8 breaths per minute.
Correct Answer: D
Rationale: The correct answer is D: Respiratory rate of 8 breaths per minute. A respiratory rate of 8 breaths per minute indicates respiratory depression, a serious side effect of morphine that can lead to respiratory arrest. Immediate intervention is crucial to prevent further complications, such as hypoxia and respiratory failure. Drowsiness, itching, and nausea are common side effects of morphine but are not life-threatening like respiratory depression. Monitoring and managing respiratory status is the top priority to ensure the client's safety and well-being.
A patient with a diagnosis of peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?
- A. With meals
- B. At bedtime
- C. Before meals
- D. After meals
Correct Answer: C
Rationale: The correct answer is C: Before meals. Omeprazole is a proton pump inhibitor that works by reducing stomach acid production. Taking it before meals allows the medication to be most effective in inhibiting the proton pumps before they are stimulated by food intake. This timing optimizes the drug's ability to reduce acid secretion during the digestion process.
Choice A (With meals) is incorrect because taking omeprazole with meals may reduce its effectiveness as it will not have enough time to inhibit acid production before food intake. Choice B (At bedtime) is also incorrect as omeprazole works best when taken before meals to prevent acid production. Choice D (After meals) is incorrect because waiting until after meals to take omeprazole means that acid production has already been stimulated by the food consumed, reducing the drug's effectiveness in inhibiting acid secretion.
A patient who is receiving chemotherapy for breast cancer develops thrombocytopenia. What should the nurse include in the care plan?
- A. Encourage light exercise.
- B. Avoid intramuscular injections.
- C. Do not administer aspirin.
- D. Use a soft toothbrush for oral care.
Correct Answer: B
Rationale: The correct answer is B: Avoid intramuscular injections. Thrombocytopenia is a condition characterized by low platelet count, which can lead to impaired blood clotting. Intramuscular injections can cause bleeding and bruising due to the decreased ability of blood to clot. Therefore, it is crucial to avoid invasive procedures like intramuscular injections to prevent excessive bleeding in patients with thrombocytopenia. Encouraging light exercise (choice A) can be beneficial for overall health but may not directly address the risk of bleeding. Avoiding aspirin (choice C) is important as it can further increase the risk of bleeding. Using a soft toothbrush for oral care (choice D) is a good practice, but it does not directly address the risk associated with intramuscular injections in patients with thrombocytopenia.
What is the primary action of a short-acting beta2-agonist (SABA) prescribed to a patient with an acute asthma exacerbation?
- A. Reduce inflammation
- B. Relieve bronchospasm
- C. Thin respiratory secretions
- D. Suppress cough
Correct Answer: B
Rationale: The correct answer is B: Relieve bronchospasm. Short-acting beta2-agonists (SABAs) like albuterol act by stimulating beta2 receptors in the airway smooth muscle, leading to bronchodilation and relieving bronchospasm. This helps to quickly open up the airways during an acute asthma exacerbation. Choice A is incorrect because SABAs do not directly reduce inflammation. Choice C is incorrect as SABAs do not affect respiratory secretions. Choice D is incorrect as SABAs do not suppress cough but rather target bronchospasm.
Why is a client with ascites scheduled for a paracentesis procedure?
- A. To diagnose liver disease
- B. To relieve abdominal pressure
- C. To assess kidney function
- D. To reduce blood pressure
Correct Answer: B
Rationale: The correct answer is B: To relieve abdominal pressure. Paracentesis is performed to drain excess fluid from the abdominal cavity, which helps alleviate symptoms like abdominal distension and discomfort in clients with ascites. It does not serve the purpose of diagnosing liver disease (A), assessing kidney function (C), or reducing blood pressure (D). The primary goal of paracentesis in this context is to provide symptomatic relief by removing the accumulated fluid, thereby reducing pressure on surrounding organs and improving the client's comfort and overall well-being.
