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. "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 B
Explanation
A. Monitoring the patient's breathing and reviewing the patient's arterial blood gases:
Rationale: While respiratory status is crucial in any patient assessment, arterial blood gases primarily evaluate respiratory function. Neutropenia directly affects the immune system, not respiratory function.
Appropriateness: Not directly related to assessing neutropenia.
B. Monitoring the patient's temperature and reviewing the patient's complete blood count with differential:
Rationale: Neutropenia can cause fever due to the increased risk of infection. Monitoring temperature and reviewing the complete blood count (CBC) with differential, specifically the neutrophil count, is essential in evaluating neutropenia and identifying potential infections.
Appropriateness: Correct. Monitoring temperature and reviewing CBC with differential are crucial in assessing neutropenia.
C. Monitoring the patient's blood pressure and reviewing the patient's hematocrit:
Rationale: Blood pressure assessment and hematocrit evaluation are essential aspects of general patient care but are not specific to neutropenia.
Appropriateness: Not directly related to assessing neutropenia.
D. Monitoring the patient's heart rate and reviewing the patient's hemoglobin:
Rationale: Heart rate monitoring and hemoglobin assessment are crucial in various clinical situations but are not specific indicators of neutropenia.
Appropriateness: Not directly related to assessing neutropenia.
