A nurse is providing teaching to a client who is pregnant and is vegan. The nurse should instruct the client that which of the following foods is a reliable source of Vitamin B12?

A. This option is not the best source of protein. While avocados are nutritious and contain healthy fats, they are low in protein. One cup of pureed avocado contains approximately 3 grams of protein, which is relatively low compared to other protein-rich foods. It’s better for providing healthy fats rather than substantial protein needed for wound healing.
B. This is the best source of protein among the choices. Lentils are an excellent source of plant-based protein, providing about 18 grams of protein per cup. They are also rich in fiber, vitamins, and minerals. For someone on a vegan diet, lentils can effectively support protein needs essential for wound healing and overall recovery.
C. This option is not the best source of protein. Brown rice is a good source of carbohydrates and provides about 5 grams of protein per cup, but it is not as protein-dense as lentils. While brown rice can be part of a balanced diet, it does not provide as much protein as lentils or other high-protein vegan foods.
D. This option does not provide significant protein. Orange juice is rich in vitamin C, which is important for wound healing, but it contains negligible protein. It's not a protein source and should not be relied upon for meeting protein needs.

A. H2RAs are not typically associated with causing or alleviating diarrhea. Their primary function is to reduce gastric acid secretion, which is not directly related to diarrhea. Therefore, cessation of diarrhea is not an indicator of the therapeutic effect of an H2RA.
B. Heartburn is a common symptom associated with excess stomach acid, often due to conditions like GERD. H2RAs work by decreasing the amount of acid produced in the stomach, which helps relieve heartburn. Therefore, relief of heartburn is a direct indication that the H2RA is achieving its therapeutic effect.
C. Constipation is not a common effect of H2RAs; instead, it is often more related to other types of medications or dietary issues. Since H2RAs are designed to reduce stomach acid and not to affect bowel movements, the absence of constipation is not a relevant outcome for assessing the effectiveness of an H2RA.
D. Flatus, or gas, is not directly affected by H2RAs. The primary purpose of H2RAs is to manage acid- related conditions, and while gastrointestinal symptoms might be related, passage of flatus is not a specific indicator of the effectiveness of an H2RA.
