A client receiving parnate (tranylcypromine) is admitted in hypertensive crisis. Which food is capable of producing a hypertensive crisis when taken with the medication?

Appeared in: DHS 2018 shift 1st

Explanation

Tranylcypromine (Parnate) is a Monoamine Oxidase Inhibitor (MAOI) antidepressant.
MAOIs block the enzyme that metabolizes tyramine, an amino acid found in certain foods.
Cheddar cheese is an aged cheese, a process that significantly increases its tyramine concentration.
Ingesting high-tyramine foods like cheddar cheese while taking an MAOI can trigger a massive release of norepinephrine, leading to a life-threatening hypertensive crisis.

Why Other Options Were Wrong

Option A: Processed cheese (like American cheese) is generally not aged and has a low tyramine content, making it a much safer option than aged cheeses.
Option B: Cottage cheese is a fresh, unaged cheese. It contains negligible amounts of tyramine and is considered safe for patients taking MAOIs.
Option C: Cream cheese is also a fresh, unripened cheese with very low levels of tyramine, making it a safe choice for individuals on MAOI therapy.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain MAOI drug-food interaction (tyramine-induced hypertensive crisis) as background academic context rather than a clinical decision trigger.
Patient education is a critical nursing responsibility for anyone prescribed MAOIs to prevent this life-threatening interaction. A list of restricted foods must be provided and understood.
Nurses must teach patients to recognize the signs of a hypertensive crisis (severe headache, stiff neck, palpitations, nausea) and to seek immediate medical help if they occur.
Dietary restrictions must be continued for about two weeks after stopping the MAOI to allow the body to regenerate the monoamine oxidase enzyme.

How to Approach the Question

First, identify the drug class: Recognize 'parnate (tranylcypromine)' as a Monoamine Oxidase Inhibitor (MAOI).
Next, recall the primary contraindication for MAOIs, which is the strict avoidance of tyramine-rich foods.
Then, link the food type to tyramine content. Remember that aged, fermented, or cured foods have high levels of tyramine.
Evaluate the options provided by assessing each cheese based on its production method.
Differentiate between aged versus fresh cheese. Identify 'Cheddar cheese' as an aged cheese, while cottage, cream, and most processed cheeses are fresh or minimally aged.
Finally, conclude the cause by selecting Cheddar cheese as the food capable of causing a hypertensive crisis when consumed with an MAOI.
