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?

A.

pH, 7.32; pCO2, 47 mm Hg; HCO3, 29 mEq/L; pO2, 80.

B.

pH, 7.34; pCO2, 49 mm Hg; HCO3, 27 mEq/L; pO2, 77.

C.

pH, 7.38; pCO2, 40 mm Hg; HCO3, 25 mEq/L; pO2, 88.

D.

pH, 7.48; pCO2, 43 mm Hg; HCO3, 23 mEq/L; pO2, 85.

Answer and Explanation

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 B

Explanation

The client bears weight on both feet when moving the walker ahead and steps with the weaker leg first. This is the proper way to use a walker for ambulation, as it provides stability and reduces stress on the affected joints.

Choice A is wrong because the client should not look down at his feet to prevent falling, but rather look ahead at where he is going. Looking down can cause neck strain and loss of balance.

Choice C is wrong because the client should not place her full weight on the walker with her arms while taking steps, as this can cause upper extremity fatigue and injury. The client should use the walker as a support, not a crutch.

Choice D is wrong because the client should not lean forward at a 60-degree angle while stepping into the walker, as this can cause back pain and poor posture. The client should stand upright and move the walker forward about one step’s length at a time.

Correct Answer is B

Explanation

This is because itching is a subjective assessment finding, which means it is based on the personal experience, view or feeling of the

patient. The other choices are objective assessment findings, which means they are based on observable or measurable data that the nurse can collect.

For example:

Choice A is wrong because hives are a visible skin reaction that can be seen and measured by the nurse.

Choice C is wrong because vomiting is an observable action that can be verified and recorded by the nurse.

Choice D is wrong because abdominal distension is a measurable change in the size or shape of the abdomen that can be assessed by the nurse.

Normal ranges for objective assessment findings may vary depending on the source and context, but some possible examples are:

  • Hives: No hives or rashes on the skin are normal.
  • Vomiting: No vomiting or nausea are normal.
  • Abdominal distension: Normal abdominal girth for adults ranges from 68 to 100 cm (27 to 40 inches).
