A nurse reviews the arterial blood gas (ABG) values of a client admitted with pneumonia: pH, 7.32; PaCO2, 48 mm Hg; PaO2, 70 mm Hg; and HCO3, 24 mEq/L. What do these values indicate?
Metabolic Acidosis
Respiratory Acidosis
Metabolic Alkalosis
Respiratory Alkalosis
The Correct Answer is B
A. Metabolic Acidosis
Metabolic acidosis is characterized by a low pH and low bicarbonate (HCO3) level. In this case, the pH is low (indicating acidosis), but the bicarbonate level is within the normal range, which is inconsistent with metabolic acidosis.
B. Respiratory Acidosis
This is correct. Respiratory acidosis is characterized by an elevated partial pressure of carbon dioxide (PaCO2), leading to a decrease in pH. The ABG values in this case indicate elevated PaCO2 and a low pH, consistent with respiratory acidosis.
C. Metabolic Alkalosis
Metabolic alkalosis is characterized by a high pH and high bicarbonate (HCO3) level. In this case, the pH is low (indicating acidosis), which is inconsistent with metabolic alkalosis.
D. Respiratory Alkalosis
Respiratory alkalosis is characterized by a low partial pressure of carbon dioxide (PaCO2) and a high pH. In this case, the PaCO2 is elevated, which is inconsistent with respiratory alkalosis.

Correct Answer is D
Explanation
A. Avoid the use of moisturizing lotions.
This statement is not a priority instruction. Moisturizing lotions, especially those designed for diabetic foot care, can help prevent dry skin and complications. However, it's crucial to choose appropriate, diabetes-friendly moisturizers.
B. Examine feet weekly for redness, blisters, and abrasions.
This is an important and relevant instruction. Regular foot inspections help detect any signs of injury or infection early, preventing complications, especially for individuals with peripheral neuropathy.
C. Dry feet vigorously after each bath.
This statement is not advisable. Vigorous drying can potentially harm the skin, especially for individuals with diabetes. A gentle and thorough drying is recommended to prevent skin damage.
D. Avoid hot-water bottles and heating pads.
This is a priority instruction. Patients with peripheral neuropathy may have reduced sensation in their feet, making them more susceptible to burns. Avoiding sources of excessive heat helps prevent injuries.
Correct Answer is C
Explanation
A. Persistently cold feet:
This may be a sign of poor circulation, which is more associated with peripheral vascular disease than neuropathy.
B. Acute pain, unrelieved by rest:
Acute pain is not typically associated with peripheral neuropathy. Neuropathic pain is often chronic and may include sensations like tingling or burning.
C. The presence of a tingling sensation:
This is correct. Tingling sensations, along with numbness and pain, are common symptoms of peripheral neuropathy in diabetes.
D. Pain that does not respond to analgesia:
While neuropathic pain can be challenging to manage, the primary focus is on the characteristic nature of the pain (tingling, burning) rather than its response to analgesics.
