T/F. absorption of dietary iron is regulated by this substance that is produced by the liver when iron stores are high and released to the blood to act at the surface of enterocytes and macrophages.
The statement is True.
The substance referred to in the question is hepcidin. Hepcidin is a peptide hormone that plays a crucial role in regulating iron metabolism in the body. When iron stores are high, the liver produces hepcidin and releases it into the blood to act at the surface of enterocytes (cells lining the small intestine) and macrophages (immune cells that engulf and digest foreign substances). Hepcidin functions by binding to the iron exporter ferroportin, causing its internalization and degradation, thereby reducing iron export from enterocytes and macrophages into the blood. This results in decreased absorption of dietary iron and increased retention of iron in macrophages and hepatocytes (liver cells). On the other hand, when iron stores are low, hepcidin levels decrease, allowing for increased iron absorption and release from storage sites to meet the body's needs.

When a split-brain patient is asked to pick out with her right hand an object presented in the left visual field, the patient will likely have difficulty doing so. This is because the left visual field is processed by the right hemisphere of the brain, which is not connected to the left hemisphere due to the corpus callosum being severed in split-brain patients. As a result, the patient's left hemisphere (which controls the right hand) will not receive the information about the object presented in the left visual field, and the patient may not even be aware that there was an object there.
When a person has undergone a split-brain procedure, it means that the corpus callosum, the bundle of nerve fibers connecting the left and right hemispheres of the brain, has been surgically severed.

A nurse planning to perform a blood transfusion should plan to check vital signs before the transfusion, insert an IV with a 19-gauge needle, and check the expiration date of the blood product with a second nurse. So, the correct answer is option B.
In more detail, checking the patient's vital signs before the transfusion helps ensure their stability and safety. Using a 19-gauge needle allows for the efficient flow of blood without causing discomfort to the patient. It is essential to check the expiration date of the blood product with a second nurse to minimize the risk of transfusion errors. However, priming the blood tubing with dextrose 5% in water is not recommended, as it may cause hemolysis.
