NAIL IN FOOT:
If your foot wound is bleeding from the nail, put a towel over it to stop the bleeding. Then use water to clean the wound. If you have any antibiotic cream, apply that and cover your wound with either bandages or some old pieces of clothes.
SWOLLEN TOE:
Raise and rest your foot with the swollen toe when you can. Put some ice wrapped in a towel on the toe for up to 20 minutes every 2 to 3 hours. Take a paracetamol if you can. Do not walk or stand for long period of times if it hurts a lot.

Answer:
The correct pathway for oxygen-poor blood is right atrium → right ventricle → pulmonary artery → lungs (first option).
Explanation:
Unoxygenated or oxygen-poor blood is that which comes from tissues that have exchanged O₂ for CO₂. The venous return is in charge of taking that blood to the heart and then to the lungs.
- Oxygen-poor blood reaches the <u>right atrium</u> from the vena cava.
- From the atrium the blood passes to the <u>right ventricle</u> through the tricuspid valve.
- The <u>right ventricle pumps the blood to the lungs</u> through the pulmonary arteries, the only arteries that carry venous blood.
Once in the lungs, the blood exchanges CO₂ for O₂, returning to the heart through the pulmonary veins.
The other options are not correct because:
- <em><u>Left atrium, left ventricle, aorta, body</u></em><em> corresponds to the flow of oxygenated blood that comes from the lungs and is pumped to the entire body.</em>
- <em><u>Left atrium, right atrium, left ventricle, right ventricle</u></em><em> not correspond to the order in which blood flows through the heart.</em>
- <em><u>Right ventricle, right atrium, pulmonary veins, lungs</u></em><em> not correspond to the flow of oxygen-poor blood.</em>
