The initial measures for the treatment of angina typically involve the use of beta blockers, nitroglycerin (often referred to as "nitro"), and encouraging the patient to rest. Beta blockers work by reducing heart rate and myocardial oxygen demand, which can alleviate the symptoms of angina. Nitroglycerin acts as a vasodilator, helping to relieve chest pain by widening the blood vessels, thus improving blood flow to the heart. Resting is also critical as it decreases the workload on the heart, allowing for better myocardial oxygen supply and demand balance during an angina episode.

Other choices like increasing fluid intake are not standard or effective measures in the immediate management of angina. Antibiotics are not indicated unless there is a specific concern about an infection, which is not typically the case in angina. Lifestyle changes can be beneficial for long-term management and prevention of angina but are not necessarily considered immediate treatment measures during an episode. Therefore, the combination of beta blockers, nitroglycerin, and rest is the correct and standard approach for treating angina acutely.
