Which of the following should be included in the teaching plan for a patient receiving glargine (Lantus), "peakless" basal insulin?
It is rapidly absorbed, has a fast onset of action
Administer the total daily dosage in two doses
Draw up the drug first, then add regular insulin
Do not mix with other insulins
The Correct Answer is D
A. It is rapidly absorbed, has a fast onset of action:
Explanation: This statement is incorrect. Glargine (Lantus) actually has a slow onset of action and a prolonged duration of action. It is formulated to provide a steady level of insulin in the body over an extended period.
B. Administer the total daily dosage in two doses:
Explanation: This is not the recommended administration for glargine. It is typically administered once daily to provide basal insulin coverage over a 24-hour period.
C. Draw up the drug first, then add regular insulin:
Explanation: Mixing glargine with other insulins is not recommended. Glargine should be administered separately to maintain its extended duration of action. It should not be mixed with other insulins in the same syringe.
D. Do not mix with other insulins:
Explanation: This is the correct statement. Glargine should not be mixed with other insulins. It should be administered alone to maintain its "peakless" basal coverage. Mixing it with other insulins could alter its pharmacokinetics and compromise its effectiveness.

Correct Answer is A
Explanation
A. Respiratory acidosis:
This occurs when there is inadequate removal of carbon dioxide (CO2) by the respiratory system. In the case of the patient post-op from knee surgery receiving Morphine, the opioid can cause respiratory depression, leading to the retention of CO2 and the development of respiratory acidosis. Signs include a decreased respiratory rate and drowsiness.
B. Hypokalemia:
This is a condition characterized by low levels of potassium in the blood. While opioids can cause constipation, they are not directly associated with hypokalemia.
C. Metabolic acidosis:
This occurs when there is an increase in acid production or a loss of bicarbonate, leading to an imbalance in the body's acid-base status. The symptoms of metabolic acidosis are not typically associated with opioid use.
D. Respiratory alkalosis:
This occurs when there is excessive elimination of CO2, leading to decreased carbon dioxide levels in the blood. Opioids, especially in higher doses, are more likely to cause respiratory depression and acidosis rather than alkalosis. The patient's low respiratory rate and drowsiness are indicative of respiratory acidosis rather than alkalosis.
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.
