A nurse is providing teaching to a client who has diabetes mellitus about the glycosylated hemoglobin blood test. Which of the following statements by the client indicates an understanding of this test?

A) Potatoes: Potatoes are generally safe to consume while taking an MAOI. They do not contain significant amounts of tyramine, which is the substance that can interact dangerously with MAO inhibitors. Thus, they are not contraindicated.

B) Grapefruit: While grapefruit can interact with various medications by affecting liver enzymes, it is not specifically contraindicated with MAOIs. The main concern with MAOIs relates to tyramine-containing foods rather than grapefruit.

C) Cheese: Certain types of cheese, particularly aged cheeses, contain high levels of tyramine. Consuming tyramine while on an MAOI can lead to hypertensive crises, which are potentially life-threatening. Therefore, cheese is contraindicated for clients taking MAOIs, making it crucial for clients to avoid these foods.

D) Eggs: Eggs are considered safe for consumption with MAOIs, as they do not contain tyramine. They do not pose the same risk as high-tyramine foods and can be included in the diet without concern for interactions.

A) This statement demonstrates an understanding of infection prevention related to chickenpox. The contagious period for chickenpox is typically considered to end once the sores have crusted over, making it safe to visit a person who has had chickenpox after this time. This reflects appropriate awareness of infectious disease protocols.

B) This statement reflects a misunderstanding about antibiotic use, as antibiotics are ineffective against viral infections. Taking antibiotics when they are not needed can lead to antibiotic resistance and other complications, highlighting the importance of understanding when to use these medications.

C) Washing hands for only 10 seconds, even with hot water, is insufficient for effective hand hygiene. The Centers for Disease Control and Prevention (CDC) recommends washing hands for at least 20 seconds to effectively remove pathogens, especially after gardening, which can introduce soilborne pathogens.

D) Cleaning a cat's litter box during pregnancy poses a risk for toxoplasmosis, a parasitic infection that can have serious consequences for the fetus. Pregnant women are advised to avoid this task or take precautions if they must do it, demonstrating a lack of understanding of specific infection risks associated with pregnancy.
