Correct Answer: B

Rationale: SBAR is a structured form of communication used in healthcare settings. It stands for Situation, Background, Assessment, and Recommendation. In this scenario, informing the on-call physician about the client's allergies to morphine & codeine falls under the 'Background' component of the SBAR format, making choice B the correct answer.

Correct Answer: B

Rationale: Assessing the client's respiratory status is the priority as it helps determine if the weight gain is due to fluid retention affecting breathing. This assessment is crucial in addressing the immediate concern of potential respiratory distress before implementing interventions like fluid restriction, diuretics, or notifying the healthcare provider.

Correct Answer: D

Rationale: Placing the client in a high Fowler's position is the best action in this situation as it helps to maximize lung expansion, improve breathing, and decrease the work of breathing. This position allows for better chest expansion, improving oxygenation and ventilation for the client in respiratory distress.

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: 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.
