Correct Answer: C

Rationale: Morning stiffness lasting more than 30 minutes is a hallmark symptom of rheumatoid arthritis. This prolonged morning stiffness is typically a distinguishing feature of rheumatoid arthritis compared to other types of arthritis, making it the most characteristic assessment finding for this disease.

Correct Answer: C

Rationale: The Joint Commission's Core Measures set for MI includes percutaneous coronary intervention within 90 minutes of the diagnosis of myocardial infarction. Since the client presented at 1500 (3:00 PM), the percutaneous coronary intervention should be performed no later than 1630 (4:30 PM), to adhere to the 90-minute timeline for optimal outcomes.

Correct Answer: B

Rationale: During an acute asthma attack, the priority is to quickly relieve bronchospasm and improve breathing. Short-acting beta agonists, like albuterol, are the first-line medications as they rapidly relax bronchial muscles, providing immediate relief. Oral corticosteroids are used as adjunct therapy to reduce airway inflammation over time, while leukotriene receptor antagonists and long-acting beta agonists are not appropriate for immediate relief during an acute attack.

Correct Answer: A

Rationale: The ECG strip shows sinus bradycardia, which is common in clients with an inferior wall MI. This rhythm can lead to decreased perfusion due to bradycardia and blocks. The most crucial initial action for the nurse is to assess the client's hemodynamic status, including blood pressure and level of consciousness. This assessment will help determine the immediate needs of the client. Calling the health care provider or the Rapid Response Team, obtaining a permit for a pacemaker insertion, or preparing to administer antidysrhythmic medication may be necessary based on the assessment findings, but the priority is to evaluate the client's current condition first.

Correct Answer: B

Rationale: Absent breath sounds may indicate a pneumothorax, a serious complication post lung biopsy. This condition requires immediate attention to prevent respiratory distress.
