Explanation:

Analyze the purpose of nitroglycerin transdermal patches

Nitroglycerin transdermal patches are used for the long-term prophylaxis of angina pectoris. Because they release medication slowly through the skin, they are not intended for immediate relief of acute chest pain attacks.

Evaluate the first option

The statement "I should apply a patch every 5 minutes if I develop chest pain" is incorrect. Transdermal patches have a slow onset of action and are not used to treat acute anginal attacks. Sublingual nitroglycerin tablets or sprays are used for acute attacks.

Evaluate the second option

The statement "I will take the patch off right after my evening meal" is correct. To prevent the development of nitrate tolerance, patients must have a daily "patch-free" interval of 10 to 12 hours. Applying the patch in the morning and removing it in the evening (often after dinner or before bedtime) ensures this necessary drug-free period.

Evaluate the third option

The statement "I will leave the patch off at least 1 day each week" is incorrect. The patch-free interval must occur daily (for 10 to 12 hours each day) to prevent tolerance, not just once a week.

Evaluate the fourth option

The statement "I should discard the used patch by flushing it down the toilet" is incorrect. Used patches still contain active medication and should be folded in half with the sticky sides together and discarded in a closed container out of reach of children and pets, not flushed down the toilet.

Answer:

• "I should apply a patch every 5 minutes if I develop chest pain."
• "I will take the patch off right after my evening meal." (Correct answer)
• "I will leave the patch off at least 1 day each week."
• "I should discard the used patch by flushing it down the toilet."
