A nurse is collecting data on a client who has oxygen toxicity. Which of the following findings should the nurse expect?

Choice A: Iron supplements are used to treat iron-deficiency anemia, but they can also reduce the motility of the gastrointestinal tract and make the stools harder and drier¹². This can lead to difficulty in passing stools and increased straining.
Choice B: Magnesium-containing antacids are used to treat heartburn and acid reflux, but they can also have a laxative effect and cause diarrhea¹³. This is because magnesium draws water into the intestines and stimulates bowel movements.
Choice C: Antibiotics are used to treat bacterial infections, but they can also disrupt the normal flora of the gut and cause diarrhea¹⁴. This is because antibiotics can kill the beneficial bacteria that help digest food and prevent the overgrowth of harmful bacteria that cause inflammation and infection.
Choice D: Anticholinergics/antispasmodics are used to treat overactive bladder, irritable bowel syndrome, and other conditions that involve muscle spasms in the gut, but they can also slow down the movement of the intestines and relax the muscles that help push the stools out¹ . This can lead to reduced frequency and difficulty in defecation.
Choice E: Opioid narcotics are used to treat moderate to severe pain, but they can also block the signals from the brain to the gut and inhibit the contraction of the intestinal muscles¹ . This can lead to decreased bowel activity and accumulation of hard and dry stools.

Choice A reason: The pulmonary artery is the large blood vessel that carries deoxygenated blood from the right ventricle to the lungs for gas exchange. It is the only artery that carries deoxygenated blood in the body.

Choice B reason: The pulmonary veins are the blood vessels that carry oxygenated blood from the lungs to the left atrium. They are the only veins that carry oxygenated blood in the body.

Choice C reason: The left ventricle is the chamber of the heart that pumps oxygenated blood to the rest of the body through the aorta. It does not directly connect to the lungs.

Choice D reason: The left atrium is the chamber of the heart that receives oxygenated blood from the pulmonary veins. It does not directly connect to the right ventricle.
