Correct Answer: A

Rationale: Difficulty swallowing (dysphagia) can indicate complications such as aspiration risk, which is common after a stroke due to impaired swallowing reflexes. It poses a serious threat to the client's respiratory system. Options B, C, and D are less likely to indicate immediate complications post-stroke. A slight headache is a common complaint and may not necessarily indicate a complication. High blood pressure is a known risk factor for strokes but may not be an immediate post-stroke complication unless it is severely elevated. Muscle weakness on one side is a common sign of stroke but may not directly indicate a new complication.

Correct Answer: C

Rationale: Administering prescribed anxiolytic medication is the most appropriate intervention for a client experiencing an anxiety attack. Anxiolytic medications can provide rapid relief from severe anxiety symptoms. Teaching deep breathing exercises (choice A) can be helpful for managing mild anxiety but may not be sufficient during an acute anxiety attack. Providing a quiet environment (choice B) is beneficial to reduce stimuli, but it may not address the immediate distress of an ongoing anxiety attack. Engaging the client in conversation (choice D) is generally not recommended during an anxiety attack as it can potentially exacerbate the symptoms by increasing stimulation.

Correct Answer: B

Rationale: The correct answer is B: Reduces gastric acid production. Omeprazole is a proton pump inhibitor that works by reducing gastric acid production, thereby helping to heal ulcers. While neutralizing stomach acid is associated with antacids, forming a protective barrier over ulcers is more characteristic of medications like sucralfate. The action described in choice D, increasing gastric mucus production, is not the primary mechanism of action of omeprazole in treating peptic ulcer disease.

Correct Answer: D

Rationale: Maintaining a patent airway is the priority nursing action during the immediate postoperative period for a client who just underwent a coronary artery bypass graft. This is crucial to ensure adequate oxygenation, especially in the early recovery phase. Monitoring for signs of infection, ensuring the client is pain-free, and assessing for bleeding and arrhythmias are important aspects of postoperative care but maintaining a clear airway takes precedence in this scenario to prevent hypoxia and respiratory compromise. In the immediate postoperative period, maintaining a patent airway is essential to prevent complications such as airway obstruction, hypoxia, and respiratory distress, which are critical in ensuring the client's safety and recovery.

Correct Answer: C

Rationale: The correct answer is C: 'To stimulate red blood cell production.' Epoetin alfa, such as Epogen, is used to treat anemia by stimulating red blood cell production in clients with chronic kidney disease. This medication helps increase hemoglobin levels and reduce the need for blood transfusions. Option A, 'To reduce the risk of bleeding,' is incorrect as epoetin alfa does not directly impact bleeding risk. Option B, 'To lower blood pressure,' is incorrect as epoetin alfa is not indicated for blood pressure management. Option D, 'To increase appetite,' is also incorrect as the primary goal of epoetin alfa is related to improving anemia by boosting red blood cell production.
