A client is experiencing angina and has just taken one sublingual nitroglycerin tablet. After 5 minutes, the client still reports chest pain. What should the nurse include in their teaching about the next steps? Select all that apply.

Continue with normal activity and avoid resting.

Call for emergency medical assistance before taking a second tablet.

Take two more sublingual tablets at the same time to expedite relief.

Stop all medications if the pain does not subside with the first tablet.

Take a third sublingual tablet if the pain is still not relieved after the second tablet and 5 minutes have passed.
