A nurse is teaching about denture care to the partner of a client who is unable to perform oral hygiene. Which of the following should the nurse include in the teaching?

Choice A rationale:
Cucumbers Cucumbers are not relevant to the client's medication regimen. There is no specific interaction between cucumbers and digoxin or furosemide that would require their consumption or avoidance.
Choice B rationale:
Blueberries Similarly, blueberries do not have any specific interaction with digoxin or furosemide. They are not a necessary or contraindicated food item for this client.
Choice C rationale:
Bananas The nurse should instruct the client to consume bananas. Bananas are a good dietary source of potassium. Furosemide is a loop diuretic that can cause potassium depletion, so it's important for the client to maintain adequate potassium levels. Digoxin can also affect potassium levels, potentially leading to an increased risk of digoxin toxicity if potassium is too low. Including potassium-rich foods like bananas can help mitigate these risks and maintain proper electrolyte balance.

Choice D rationale:
Green beans While green beans are a nutritious vegetable, they do not have a direct relevance to the client's medication regimen. They are not specifically indicated or contraindicated in the context of digoxin and furosemide use.

Choice A rationale:
A client whose hematocrit is 42% (Choice A) falls within the normal range for hematocrit values, which is typically around 37-52% for adult women and 40-54% for adult men. While low hematocrit values can indicate anemia, a value of 42% is not indicative of iron-deficiency anemia on its own.
Choice B rationale:
A client whose RBC count is 5.2 million/mm3 (Choice B) is within the normal range for red blood cell counts, which is roughly 4.5-5.5 million/mm3 for adult women and 4.5-6.1 million/mm3 for adult men. Although low RBC counts can be associated with anemia, the value provided is not suggestive of iron-deficiency anemia without further context.
Choice C rationale:
A client whose ferritin level is 8 ng/mL (Choice C) is the correct choice. Ferritin is a protein that stores iron, and low levels of ferritin are a strong indicator of iron-deficiency anemia. Ferritin levels less than 12 ng/mL are often considered indicative of depleted iron stores.
Choice D rationale:
A client whose hemoglobin is 15 g/dL (Choice D) falls within the normal range for hemoglobin values, which is typically around 12-15.5 g/dL for adult women and 13.5-17.5 g/dL for adult men. While low hemoglobin can suggest anemia, a value of 15 g/dL is not indicative of iron-deficiency anemia on its own.
