Question 74

Place 1 tablet under tongue as needed for chest pain.

Nitroglycerin (Nitrostat) is typically administered sublingually (under the tongue) for the rapid relief of chest pain caused by angina. The instruction "SL PRN" specifically indicates this method of administration as needed.

A) Take 1 tablet by mouth as needed for chest pain.

This option is incorrect because nitroglycerin is not typically taken by mouth like a standard oral tablet. Instead, it is designed to be placed under the tongue for quick absorption into the bloodstream, which is essential for effective relief of chest pain.

B) Inject 1 mL as needed for chest pain.

This option is incorrect as nitroglycerin is not administered via injection for chest pain in the context of a prescription like Nitrostat. The sublingual route is preferred for rapid action, while injectable forms of nitroglycerin are used in different clinical settings.

C) Place 1 tablet under tongue as needed for chest pain.

This option is correct because nitroglycerin (Nitrostat) is specifically formulated to be placed under the tongue (sublingually) to provide quick relief from angina pain. This method allows for rapid absorption and onset of action.

D) Inhale 1 spray as needed for chest pain.

This option is incorrect because it describes a different formulation of nitroglycerin that is not the sublingual tablet form. While there are nitroglycerin sprays available, the question specifically refers to Nitrostat, which is administered sublingually.

Conclusion

The correct interpretation of the nitroglycerin prescription is to place 1 tablet under the tongue as this method ensures fast relief from chest pain. Other options fail to accurately represent the proper administration route or formulation of nitroglycerin, emphasizing the importance of adhering to specific instructions for effective treatment.
