A nurse is reviewing information about advance directives with a newly admitted client. Which of the following statements by the client indicates an understanding of the information?

The client's symptoms are concerning for angina or a possible myocardial infarction (heart atack) and require immediate intervention. Nitroglycerin is a medication that can help relieve chest pain associated with cardiac events by dilating blood vessels and reducing the workload on the heart.

Therefore, the nurse should administer nitroglycerin as ordered by the provider. After administering nitroglycerin, the nurse should obtain an ECG to assess for any changes in cardiac rhythm or evidence of ischemia (lack of blood flow to the heart muscle).

The ECG can provide important diagnostic information and guide further treatment decisions.

Tranylcypromine is a monoamine oxidase inhibitor (MAOI) medication used to treat depression. MAOIs inhibit the activity of the enzyme monoamine oxidase, which helps regulate the breakdown of certain neurotransmitters, including tyramine. Tyramine is typically broken down by monoamine oxidase, but when taking an MAOI, the enzyme's inhibition can lead to an excessive accumulation of tyramine in the body.

Tyramine-rich foods, such as aged cheeses, cured meats, and certain fermented or pickled foods, contain high levels of tyramine. Ingesting these foods while taking an MAOI can lead to a sudden release of stored norepinephrine, causing a hypertensive crisis.

Hypertension is a potentially serious adverse effect of MAOI therapy combined with tyramine-rich food ingestion. Symptoms of a hypertensive crisis can include severe headache, palpitations, chest pain, sweating, blurred vision, and in severe cases, it can lead to stroke or other cardiovascular complications.

Hematuria refers to the presence of blood in the urine and is not a known adverse effect of tranylcypromine or related to tyramine-rich food ingestion.

Tinnitus refers to the perception of ringing or noise in the ears and is not a known adverse effect of tranylcypromine or related to tyramine-rich food ingestion.

Hyperglycemia, or high blood sugar levels, is not a known adverse effect of tranylcypromine or related to tyramine-rich food ingestion. However, it's important to note that tranylcypromine may interact with certain diabetes medications, so it's essential to consider the client's overall medical history and potential drug interactions.
