A nurse is conducting a class on how to self-manage insulin regimens. A client asks how long a vial of insulin can be stored at room temperature before it "goes bad." What would be the nurse's best answer?
"If a vial of insulin will be used up within 21 days, it may be kept at room temperature."
"If a vial of insulin will be used up within 2 weeks, it may be kept at room temperature."
"If you are going to use up the vial within 1 month, it can be kept at room temperature."
"If a vial of insulin will be used up within 1 week, it may be kept at room temperature."
The Correct Answer is A
A. "If a vial of insulin will be used up within 21 days, it may be kept at room temperature."
This statement suggests a duration of up to 21 days for room temperature storage after the vial is in use. However, most insulins can typically be stored at room temperature for up to 28 days after initial use. This recommendation might be more conservative than necessary for many types of insulin.
B. "If a vial of insulin will be used up within 2 weeks, it may be kept at room temperature."
This choice suggests a timeframe of 14 days for room temperature storage after opening the vial. However, for many insulins, the recommended duration for room temperature storage after opening is up to 28 days.
C. "If you are going to use up the vial within 1 month, it can be kept at room temperature."
This option extends the timeframe to 1 month for room temperature storage after the vial is in use. However, the generally recommended duration for many insulins is up to 28 days after opening.
D. "If a vial of insulin will be used up within 1 week, it may be kept at room temperature."
This choice suggests a very short duration of 7 days for room temperature storage after opening the vial. Most insulins can typically be stored at room temperature for a longer duration after initial use.

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. pH 7.28, pCO2 36, HCO3 23:
Explanation: The pH is low, indicating acidosis. However, the pCO2 is within the normal range, which is not consistent with respiratory acidosis. The HCO3 is slightly low but not significantly, and this doesn't align with typical findings in respiratory acidosis.
B. pH 7.52, pCO2 28, HCO3 25:
Explanation: The pH is high, indicating alkalosis. The pCO2 is below the normal range, which is not consistent with respiratory acidosis. The HCO3 is within the normal range, and these values are not typical for respiratory acidosis.
C. pH 7.25, pCO2 50, HCO3 22:
Explanation: The pH is low, indicating acidosis. The pCO2 is elevated, which is typical in respiratory acidosis. The HCO3 is within the normal range, suggesting uncompensated respiratory acidosis.
D. pH 7.35, pCO2 40, HCO3 24:
Explanation: The pH is within the normal range, and both pCO2 and HCO3 are normal. These values do not indicate acidosis.
