Diabetes Insulin Therapy 5

Question 1

Which insulin requires a prescription but can be purchased over the counter at most US pharmacies without prior authorization?

Accepted Answer

Regular human insulin (ReliOn) at Walmart

Answer

Regular human insulin (such as ReliOn brand) is available OTC at Walmart and some other pharmacies at low cost, though analog insulins require a prescription.

Question 2

Insulin glargine (Lantus) should NOT be mixed with other insulins because:

Accepted Answer

Its acidic pH can alter the pharmacokinetics of the mixture

Answer

Glargine's acidic pH (approximately 4) is neutralized when mixed, disrupting the microprecipitate that creates its prolonged, peakless absorption.

Question 3

A patient with Type 1 diabetes on MDI wants to reduce hypoglycemia risk overnight. The best strategy is:

Accepted Answer

Use a continuous glucose monitor with low-glucose suspend feature

Answer

A CGM with low-glucose suspend automatically pauses insulin delivery when glucose falls, significantly reducing nocturnal hypoglycemia.

Question 4

Which of the following correctly describes 'basal-bolus' insulin therapy?

Accepted Answer

Long-acting insulin for background control plus rapid-acting insulin at mealtimes

Answer

Basal-bolus therapy mimics normal pancreatic function using a long-acting insulin for steady background coverage and rapid-acting insulin to cover meals.

Question 5

Severe hypoglycemia requiring assistance from another person should be treated first with:

Accepted Answer

Glucagon injection or nasal glucagon (Baqsimi) if the patient cannot swallow

Answer

When a patient is unconscious or cannot swallow, glucagon (injectable or intranasal) is the first-line emergency treatment to raise blood glucose.
