Metabolic alkalosis
Respiratory acidosis
Metabolic acidosis
Respiratory alkalosis
The Correct Answer is A
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 nausea and vomiting, as they result in the loss of gastric acid and the retention of bicarbonate.
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. It is not related to nausea and vomiting.
Choice C 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 caused by nausea and vomiting.

Correct Answer is B
Explanation
Choice A reason: The pulse oximeter might not be accurate during times of excessive movement is a correct statement, as movement can interfere with the detection of the pulse and the oxygen saturation. The parents should try to keep the infant still and calm while using the pulse oximeter.
Choice B reason: We will notify the doctor if the pulse oximeter consistently reads 100% is an incorrect statement, as it indicates a misunderstanding of the normal range of oxygen saturation. The parents should not be alarmed if the pulse oximeter reads 100%, as it means that the infant's blood is fully saturated with oxygen. The normal range of oxygen saturation for infants is 95% to 100%.
Choice C reason: The probe of the pulse oximeter can be applied to a finger or a toe is a correct statement, as these are suitable sites for measuring the oxygen saturation in infants. The parents should make sure that the probe fits snugly and securely on the infant's finger or toe.
Choice D reason: We will rotate the probe of the pulse oximeter every 24 hours is a correct statement, as it helps to prevent skin irritation, pressure ulcers, or infection from prolonged contact with the probe. The parents should also check the infant's skin regularly for any signs of redness, swelling, or pain.
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.
