Which two areas should a patient with a GI disorder be questioned about?
Choose 2 answers.

A. A complication of a medical or surgical procedure: This describes an iatrogenic pneumothorax, not a primary spontaneous pneumothorax.

B. A wound that allows air into the pleural cavity but not out: This describes a tension pneumothorax, not a primary spontaneous pneumothorax.

C. No underlying lung disease and no inciting event: A primary spontaneous pneumothorax occurs without any apparent cause or underlying lung disease, often in healthy individuals, especially young, tall, thin men.

D. Underlying lung disease as well as air entering the pleural space via ruptured blebs: This describes a secondary spontaneous pneumothorax, not a primary one.

A. Iron is a critical component of hemoglobin, the molecule in red blood cells (RBCs) that carries oxygen. Without sufficient iron, the body cannot produce enough healthy RBCs, leading to anemia.

B. Fiber is important for digestive health but does not play a role in red blood cell synthesis.

C. Magnesium is involved in many biochemical processes but is not directly required for RBC synthesis.

D. Calcium is important for bone health and various cellular functions, but it is not directly involved in red blood cell production.

E. Folic acid (vitamin B9) is essential for DNA synthesis and cell division, both of which are crucial for the production of red blood cells in the bone marrow.

F. Potassium is vital for maintaining cellular function, especially in muscles and nerves, but it is not required for RBC synthesis.
