A nurse is reviewing a client's laboratory report. The client's ABG levels are pH 7.5, PaCO2 32 mm Hg, and HCO3 24 mEq/L. The nurse should determine that the client has which of the following acid-base imbalances?
Respiratory alkalosis
Metabolic acidosis
Respiratory acidosis
Metabolic alkalosis
The Correct Answer is A
Choice A reason: This is the correct imbalance, because respiratory alkalosis is a condition that occurs when the blood pH is high, the PaCO2 is low, and the HCO3 is normal or low. Respiratory alkalosis is caused by hyperventilation, which can result from anxiety, fever, pain, or mechanical ventilation.
Choice B reason: This is an incorrect imbalance, because metabolic acidosis is a condition that occurs when the blood pH is low, the PaCO2 is normal or low, and the HCO3 is low. Metabolic acidosis is caused by the accumulation of acids in the blood, which can result from diabetic ketoacidosis, renal failure, or lactic acidosis.
Choice C reason: This is an incorrect imbalance, because respiratory acidosis is a condition that occurs when the blood pH is low, the PaCO2 is high, and the HCO3 is normal or high. Respiratory acidosis is caused by hypoventilation, which can result from airway obstruction, chest injury, or narcotic overdose.
Choice D reason: This is an incorrect imbalance, because metabolic alkalosis is a condition that occurs when the blood pH is high, the PaCO2 is normal or high, and the HCO3 is high. Metabolic alkalosis is caused by the loss of acids from the blood, which can result from vomiting, gastric suction, or diuretic therapy.

Correct Answer is D
Explanation
Choice A reason: This is a normal finding, not an indication of breast cancer. Lumps that are mobile and tender upon palpation prior to a menstrual period are usually benign and related to hormonal changes.
Choice B reason: This is a normal finding, not an indication of breast cancer. Multiple round masses that are tender and found in both breasts are usually benign and related to fibrocystic breast changes.
Choice C reason: This is a normal finding, not an indication of breast cancer. Bilaterally darkened areolas are usually benign and related to genetic factors, pregnancy, or aging.
Choice D reason: This is an abnormal finding, and an indication of breast cancer. A nontender hard lump that is palpated in one breast is usually malignant and related to abnormal cell growth.
Correct Answer is ["A","C","E"]
Explanation
Choice A reason: Checking and documenting the client's vital signs is a correct action, because it provides a baseline for comparison and helps to monitor for any signs of adverse reactions to the transfusion.
Choice B reason: Ensuring that the client's IV site uses a 22-gauge needle is an incorrect action, because a larger gauge needle (18- or 20-gauge) is preferred for blood transfusions to prevent hemolysis of the RBCs.
Choice C reason: Verifying that the blood type and Rh of the packed RBCs are checked by two nurses is a correct action, because it is a standard safety procedure to prevent transfusion errors and ensure compatibility.
Choice D reason: Obtaining a bag of lactated Ringer's IV solution is an incorrect action, because only normal saline (0.9% sodium chloride) should be used as the IV solution for blood transfusions. Other solutions may cause hemolysis or clotting of the blood.
Choice E reason: Providing the RN with tubing that has a filter is a correct action, because a filter is required for blood transfusions to remove any clumps or debris from the blood.
