A nurse is caring for a client who has chronic renal failure.
The client displays the following ABG results: pH 7.24, PaCO2 44 mm Hg, PaO2 84 mm Hg. HCO3 18 mEq/L, base excess -2, and O2 saturation 95%.
The nurse should conclude that the client has which of the following acid-base imbalances?
Respiratory acidosis.
Metabolic alkalosis.
Respiratory alkalosis.
Metabolic acidosis.
The Correct Answer is D
The client’s ABG results show a pH of 7.24, which is below the normal range of 7.35-7.45 and indicates acidosis.
The PaCO2 is within the normal range of 35-45 mm Hg, indicating that the acidosis is not caused by a respiratory issue.
The HCO3 level is 18 mEq/L, which is below the normal range of 22-28 mEq/L and indicates a primary metabolic cause for acidosis.
Respiratory acidosis is not indicated by the ABG results as the PaCO2 is within the normal range.
B) Metabolic alkalosis is not indicated by the ABG results as the pH and HCO3 levels are below their respective normal ranges.
C) Respiratory alkalosis is not indicated by the ABG results as the pH is below the normal range and the PaCO2 is within the normal range.

Correct Answer is C
Explanation
“Fluid volume excess.” Bounding pulses, crackles on auscultation, and pink frothy secretions when receiving suctioning are all signs of fluid volume excess.
Fluid volume excess can occur when the heart is unable to pump blood efficiently, causing fluid to build up in the lungs.
Choice A is not the correct answer because the increased cardiac output would not cause these symptoms.
Choice B is not the correct answer because pleural effusion refers to a buildup of fluid between the layers of tissue that line the lungs and chest cavity, which would not cause these symptoms.
Choice D is not the correct answer because aspiration refers to the inhalation of food, liquid, or other substances into the lungs, which would not cause these symptoms.
Correct Answer is A
Explanation
Acupuncture is commonly used to treat a wide range of illnesses and ailments including pain management, control of nausea and vomiting, fatigue, hot flashes, xerostomia, neuropathy, anxiety, depression, and sleep disturbance in cancer patients.
However, I could not find any information that suggests mouth sores (B), headaches, or urticaria (D) are contraindications for acupuncture.
Lymphedema is a contraindication for acupuncture because it can increase the risk of infection in the affected area.
It is important for the nurse to identify this as a contraindication to receiving acupuncture therapy.
