Which insulin is used for basal dosing for 24-hour coverage and has no peak?
Lispro (Humalog).
Aspart (NovoLog).
Regular insulin (Humulin R).
Glargine (Lantus). . .
The Correct Answer is D
Choice A rationale
Lispro (Humalog) is a rapid-acting insulin used for mealtime glucose control. It has an onset of 15 minutes and peaks within 30 minutes to 1 hour, making it unsuitable for basal dosing.
Choice B rationale
Aspart (NovoLog), another rapid-acting insulin, is similar to lispro in its onset and peak times. It is also used for mealtime glucose control, not basal glucose regulation.
Choice C rationale
Regular insulin (Humulin R) is a short-acting insulin with an onset of 30 minutes to 1 hour and a peak of 2 to 4 hours. It cannot provide the steady basal glucose control required for 24-hour coverage.
Choice D rationale
Glargine (Lantus) is a long-acting insulin that provides consistent basal glucose control with no pronounced peak. It is designed for once-daily dosing to maintain stable glucose levels over 24 hours, meeting the requirements for basal dosing. .

Correct Answer is ["A","D"]
Explanation
Choice A rationale
Using a urine filter ensures the recovery of passed stones for laboratory analysis, assisting in identifying stone composition and tailoring prevention strategies.
Choice B rationale
Calcium intake is essential for bone health and reducing oxalate absorption. Avoiding calcium increases oxalate availability, worsening stone formation.
Choice C rationale
Diuretic fluids like coffee promote dehydration and concentration of urine, increasing the risk of stone recurrence. Diuretics should be prescribed for specific stone types.
Choice D rationale
Maintaining hydration prevents urine concentration and the supersaturation of stone-forming crystals, which are primary risk factors for nephrolithiasis.
Correct Answer is B
Explanation
Choice A rationale
Endoscopy is a diagnostic procedure used for evaluating persistent or severe symptoms of heartburn, but it is not part of initial treatment. Patient education focuses on symptom relief and management strategies before invasive testing.
Choice B rationale
Proton pump inhibitors reduce gastric acid secretion by irreversibly blocking H+/K+ ATPase in stomach parietal cells. They are first-line medications for heartburn and gastroesophageal reflux disease, effectively relieving symptoms and preventing complications.
Choice C rationale
Radionuclide tests are specialized diagnostic procedures for conditions such as gastric emptying disorders. They are not standard educational topics for new heartburn complaints, as they do not provide immediate symptom relief.
Choice D rationale
A barium swallow is used for imaging structural abnormalities of the esophagus or stomach but is not part of initial management for heartburn. It is a diagnostic tool rather than a first-line treatment or educational focus. .
