NCLEX Review from Passpoint

The nurse is teaching a client and family about phenelzine. Which food should the nurse instruct the client to avoid?

Sour Cream. Explanation: Because phenelzine is a monoamine oxidase inhibitor, the client should avoid foods high in tyramine to prevent the development of hypertensive crisis. Foods and beverages high in tyramine include sour cream, aged cheeses, yogurt, red wine, beer, bananas, avocados, salami, sausage, bologna, caffeinated coffee and colas, and chocolate. High-protein foods that have undergone protein breakdown by aging, fermentation, pickling, or smoking should be avoided. Hypertensive crisis, evidenced by occipital headache, stiff neck, nausea and vomiting, sweating, nosebleed, dilated pupils, tachycardia, and constricting chest pain, can occur with this food-drug combination. Eggs, chicken, and peanut butter are not foods high in tyramine and can be included in the client's diet.

When inspecting a client's skin, a nurse finds a circumscribed elevated area filled with serous fluid. What term should the nurse use to document this finding? vesicle, macule, pustule, papule?

Vesicle. Explanation: A vesicle is a circumscribed skin elevation filled with serous fluid. A flat, nonpalpable, colored spot is a macule. A solid, elevated, circumscribed lesion is a papule. An elevated, pus-filled, circumscribed lesion is a pustule.

A client develops a facial rash and urticaria after receiving penicillin. Which laboratory value does the nurse expect to be elevated?

IgE. Explanation: Immunoglobulin E (IgE) is involved with an allergic reaction. IgA combines with antigens and activates the complement system. IgB coats the surface of B lymphocytes. IgG is the principal immunoglobulin formed in response to most infectious agents.
