A client with severe bronchial pneumonia has been receiving oxygen, respiratory treatments, antibiotics, and intravenous fluids.
Which arterial blood gas result would indicate that the treatment has been effective?
pH, 7.32; pCO2, 47 mm Hg; HCO3, 29 mEq/L; pO2, 80.
pH, 7.34; pCO2, 49 mm Hg; HCO3, 27 mEq/L; pO2, 77.
pH, 7.38; pCO2, 40 mm Hg; HCO3, 25 mEq/L; pO2, 88.
pH, 7.48; pCO2, 43 mm Hg; HCO3, 23 mEq/L; pO2, 85.
The Correct Answer is C
This is because it shows a normal pH, pCO2, HCO3 and pO2, indicating that the treatment has been effective in restoring normal gas exchange and acid- base balance.
Choice A is wrong because it shows a low pH, high pCO2 and high HCO3, indicating a mixed respiratory and metabolic acidosis.
Choice B is wrong because it shows a low pH, high pCO2 and low HCO3, indicating a combined respiratory and metabolic acidosis.
Choice D is wrong because it shows a high pH, low pCO2 and low HCO3, indicating a mixed respiratory and metabolic alkalosis.
The normal ranges for arterial blood gas (ABG) are:
- pH: 7.35 – 7.45
- pO2: 10 – 14 kPa or 75 – 105 mmHg
- pCO2: 4.5 – 6 kPa or 34 – 45 mmHg

Correct Answer is A
Explanation
A toileting routine is the priority intervention for a client diagnosed with total urinary incontinence because it helps to prevent skin breakdown, infection, and odor. It also promotes dignity and comfort for the client.
Choice B. Kegel exercises are wrong because they are not effective for total urinary incontinence, which is the complete loss of bladder control. Kegel exercises are more useful for stress or urge urinary incontinence, which are caused by weak pelvic floor muscles.
Choice C. Surgery is wrong because it is not a priority intervention for total urinary incontinence.
Surgery may be considered a last resort option if other conservative measures fail to improve the condition. Surgery may also have risks and complications that need to be weighed against the benefits.
Choice D. Anticholinergic drug therapy is wrong because it is not a priority intervention for total urinary incontinence.
Anticholinergic drugs are used to treat overactive bladder or urge urinary incontinence, which are caused by involuntary bladder contractions. Anticholinergic drugs may have side effects such as dry mouth, constipation, blurred vision, and confusion.
