A nurse is developing a program about strategies to prevent foodborne illnesses for a community group. The nurse should plan to include which of the following recommendations? (Select all that apply)."

A. While milk is a good source of calcium, it is not beneficial for iron absorption. In fact, high calcium intake can inhibit iron absorption. Turkey is a good source of heme iron, which is more easily absorbed by the body compared to non-heme iron (found in plant-based sources). While turkey is beneficial, the combination with milk is not ideal due to the calcium interfering with iron absorption.
B. Like milk, yogurt is rich in calcium. Calcium can inhibit iron absorption, making yogurt less ideal for improving iron levels if consumed in large amounts with iron-rich foods. This is also a dairy product high in calcium. Combining it with yogurt does not enhance iron absorption and can hinder it.
C. Spinach is a good source of non-heme iron, though it contains oxalates, which can inhibit iron absorption. However, spinach can still contribute to overall iron intake. Beef is an excellent source of heme iron, which is easily absorbed by the body. Combining beef with spinach can help improve overall iron intake, despite the oxalates in spinach.
D. Fish, such as salmon or tuna, is a good source of heme iron, which is beneficial for increasing iron levels. Cottage cheese is a dairy product high in calcium, which can inhibit iron absorption if consumed in large amounts.

A. This term refers to the presence of excess fat in the stool, which makes it appear greasy or oily. Steatorrhea is usually associated with malabsorption issues such as celiac disease or chronic pancreatitis. The guaiac test does not detect steatorrhea; it specifically tests for blood in the stool.
B. These are organisms that live in or on another organism (host) and can be detected in stool samples through different tests, such as stool ova and parasite exams. The guaiac test does not detect parasites; it is designed to identify hidden blood in the stool.
C. Various bacterial infections can be identified through stool cultures or other specific tests. The guaiac test is not used to detect bacteria; it is focused on identifying the presence of blood in the stool.
D. The guaiac test is used to detect occult (hidden) blood in the stool. The presence of blood can be an indication of gastrointestinal issues, such as bleeding from ulcers, polyps, or tumors. The test works by using a chemical reaction (with guaiac) that turns blue in the presence of hemoglobin (a component of blood).
