A nurse is reviewing a client's arterial blood gas (ABG) results. Which of the following ABG results should the nurse anticipate when caring for a client with acidosis?

pH 7.42, PaCO2 48 mm HG, HCO3 25 mEq/L

pH 7.28, PaCO2 63 mm HG, HCO3 22 mEq/L

pH 7.49, PaCO2 30 mm Hg, HCO3 35 mEq/L

pH 7.36; PaCO2 42 mm Hg, HCO3 26 mEq/L

Answer and Explanation

The Correct Answer is B

A.   This result shows a slightly elevated PaCO2, which could suggest respiratory compensation for a metabolic alkalosis, not acidosis, as the pH is within the normal range.
B.   This result indicates both a low pH and an elevated PaCO2, which are consistent with respiratory acidosis. The low HCO3 also suggests a metabolic acidosis component, making it the best match for a client with acidosis.

C.   The elevated pH indicates alkalosis. The low PaCO2 and high HCO3 further suggest a primary respiratory alkalosis with metabolic compensation.
D.   These values are within normal limits, indicating neither acidosis nor alkalosis.

Correct Answer is D

Explanation

A. "After the surgery, I will have to be careful with heavy lifting for a few weeks": This statement demonstrates understanding of postoperative precautions, as heavy lifting can strain the surgical site and delay healing.

B. "I know that after the surgery, I will only have one testicle left": This statement indicates awareness of the surgical procedure and its potential outcomes, which is accurate.

C. "I will have to take antibiotics as prescribed by my doctor to prevent infection": This statement reflects understanding of the importance of antibiotic therapy to prevent postoperative infection, which is correct.

D. "I will need to avoid showering for a month after the surgery": This statement is incorrect.

Avoiding showering for a month after surgery is unnecessary and could lead to poor hygiene and potential complications such as infection. The client should be educated that showering is typically allowed after surgery, but they should avoid soaking the incision site in water until it has healed properly.

A. "Increase your intake of grapefruit juice." B. "Expect to have increased generalized bruising." C. "Monitor for muscle pain." D. "Take this medication without food if nausea develops."

Correct Answer is C

Explanation

A. "Increase your intake of grapefruit juice."

Grapefruit juice can interact with many medications, including colchicine, potentially increasing the risk of adverse effects or reducing its effectiveness. Therefore, it is not recommended to increase grapefruit juice intake while taking colchicine.

B. "Expect to have increased generalized bruising." Increased bruising is not a common side effect of colchicine.

C. "Monitor for muscle pain."

Colchicine is associated with myotoxicity, which can manifest as muscle pain or weakness. Therefore, the client should be instructed to monitor for signs and symptoms of muscle pain and report them promptly to their healthcare provider.

D. "Take this medication without food if nausea develops."

While colchicine can cause gastrointestinal side effects such as nausea and vomiting, taking it without food may exacerbate these symptoms. It is generally recommended to take colchicine with food to minimize gastrointestinal upset.
