Rationale: In this scenario, the nurse should prioritize educating the client about the effects of cocaine on the heart and provide a referral for further help. This approach is crucial in addressing the root cause of the client's health issues and supporting them in making informed decisions about their health. Reporting the client to the police or simply explaining the damage without offering solutions may not effectively address the client's needs or promote holistic care.

Rationale: If chest pain persists after the first dose of nitroglycerin, it is appropriate to administer a second dose while continuing to monitor the client's response. Nitroglycerin is a vasodilator commonly used to relieve angina symptoms by dilating blood vessels and increasing blood flow to the heart. Reassessing the client's response and providing a second dose may be necessary to achieve adequate pain relief and improve blood flow to the heart.

Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications.
