Which of the following should be included in the teaching plan for a patient receiving glargine (Lantus), "peakless" basal insulin?

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.

A. Metabolic Alkalosis:
pH: Elevated (alkalotic).
PaCO2: Normal or slightly decreased (compensation may or may not be present).
HCO3: Elevated.
Explanation: Metabolic alkalosis is characterized by an excess of bicarbonate (HCO3) in the blood, leading to an elevated pH. In this case, the elevated pH and HCO3 levels suggest that the primary imbalance is metabolic alkalosis.

B. Respiratory Alkalosis:
pH: Elevated (alkalotic).
PaCO2: Decreased (due to hyperventilation, which blows off CO2).
HCO3: Normal or slightly decreased (compensation).
Explanation: Respiratory alkalosis is characterized by low levels of carbon dioxide (PaCO2) due to hyperventilation. However, in the provided ABG, the PaCO2 is not significantly decreased, suggesting that respiratory alkalosis is not the primary issue.

C. Respiratory Acidosis:
pH: Decreased (acidotic).
PaCO2: Increased (due to inadequate ventilation).
HCO3: Normal or slightly elevated (compensation).
Explanation: Respiratory acidosis is characterized by an increase in carbon dioxide (PaCO2) levels. In this case, the PaCO2 is within the normal range, indicating that respiratory acidosis is not the primary problem.

D. Metabolic Acidosis:
pH: Decreased (acidotic).
PaCO2: Normal or slightly decreased (compensation).
HCO3: Decreased.
Explanation: Metabolic acidosis is characterized by a decrease in bicarbonate (HCO3) levels. In this ABG, the HCO3 is elevated, ruling out metabolic acidosis as the primary issue.
