Correct Answer: A

Rationale: Thrombolytic therapy involves the use of medications to dissolve blood clots. Hip arthroplasty (joint replacement surgery) performed recently is a contraindication to thrombolytic therapy due to the risk of bleeding. Elevated sedimentation rate, exercise-induced asthma, and elevated platelet count are not contraindications to thrombolytic therapy.

Correct Answer: C

Rationale: Ethambutol is associated with potential vision changes, including optic neuritis. Patients should be instructed to report any visual disturbances immediately to prevent permanent vision loss. Monitoring for changes in vision is crucial to detect any adverse effects early on and prevent serious complications.

Correct Answer: C

Rationale: In this scenario, the client is presenting with signs of respiratory distress, including absent breath sounds, dyspnea, and a low SaO2 level. The priority action should be to improve oxygenation by administering oxygen via a high-flow mask. This intervention aims to increase the oxygen supply to the client's lungs, helping to address the hypoxemia. Once oxygenation is optimized, further interventions, such as obtaining a chest X-ray, preparing for chest tube insertion, or initiating IV access, can be considered based on the client's condition and healthcare provider's orders.

Correct Answer: B

Rationale: Vecuronium is a neuromuscular blocking agent that is used to facilitate ventilation by inducing muscle paralysis, which can help improve oxygenation in patients with ARDS. It does not treat infection, decrease inflammation, or reduce anxiety. Understanding the purpose of vecuronium administration is crucial for providing safe and effective care to patients with respiratory distress.

Correct Answer: C

Rationale: Albuterol is a bronchodilator commonly used to treat conditions like COPD. One of its common side effects is an increase in heart rate (tachycardia) due to its action on beta-2 receptors in the body. This statement by the client demonstrates an understanding of a potential side effect of albuterol, indicating comprehension of the discharge teaching provided by the healthcare provider.
