A nurse is caring for a client who has COPD. The nurse should identify that the client is at risk for which of the following acid-base imbalances?
Metabolic alkalosis
Respiratory acidosis
Respiratory alkalosis
Metabolic acidosis
The Correct Answer is B
Choice A reason: Metabolic alkalosis is a condition in which the blood pH is elevated due to an excess of bicarbonate or a loss of acid. It can be caused by vomiting, diuretics, or excessive antacid intake. It is not associated with COPD.
Choice B reason: Respiratory acidosis is a condition in which the blood pH is lowered due to an accumulation of carbon dioxide. It can be caused by hypoventilation, airway obstruction, or lung diseases such as COPD. It is the most common acid-base imbalance in COPD patients.
Choice C reason: Respiratory alkalosis is a condition in which the blood pH is elevated due to a loss of carbon dioxide. It can be caused by hyperventilation, anxiety, fever, or aspirin overdose. It is not common in COPD patients.
Choice D reason: Metabolic acidosis is a condition in which the blood pH is lowered due to an excess of acid or a loss of bicarbonate. It can be caused by diabetic ketoacidosis, renal failure, or lactic acidosis. It is not directly related to COPD.

Correct Answer is ["A","C"]
Explanation
Choice A reason: Ignoring the urge to defecate is a cause of constipation, as it can lead to hardening and accumulation of stool in the colon. The nurse should advise the client to respond to the urge to defecate as soon as possible and to establish a regular bowel routine.
Choice B reason: Increased fiber in the diet is not a cause of constipation, but rather a prevention measure. Fiber helps to soften the stool and increase its bulk, which facilitates its passage through the colon. The nurse should encourage the client to consume adequate amounts of fiber from fruits, vegetables, whole grains, and legumes.
Choice C reason: Excessive laxative use is a cause of constipation, as it can interfere with the normal functioning of the colon and cause dependency. The nurse should instruct the client to avoid using laxatives unless prescribed by the provider and to use them only for a short period of time.
Choice D reason: Increased activity is not a cause of constipation, but rather a prevention measure. Activity helps to stimulate the peristalsis of the colon and promote bowel movements. The nurse should recommend the client to engage in moderate physical activity for at least 30 minutes a day
Correct Answer is A
Explanation
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.
