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 D
Explanation
Choice A rationale
Chewing gum can increase salivary production, and while saliva may neutralize some stomach acid, the act of chewing can stimulate swallowing and possibly exacerbate symptoms by introducing excess air into the stomach. For GERD patients, avoiding gum may help reduce bloating and gas discomfort.
Choice B rationale
Elevating the head of the bed reduces the likelihood of acid reflux during sleep by using gravity to prevent stomach contents from flowing backward into the esophagus. This strategy aligns with GERD management guidelines and reduces nighttime symptoms.
Choice C rationale
Taking antacids between meals and at bedtime helps neutralize stomach acid temporarily, providing short-term relief of GERD symptoms. While effective, long-term use without addressing dietary and lifestyle factors is not ideal for managing GERD.
Choice D rationale
Eating small meals is beneficial for GERD, as it prevents overdistension of the stomach, but having a bedtime snack contradicts GERD management principles. Late-night eating may increase the risk of acid reflux when lying down, thus requiring more teaching.
Correct Answer is A
Explanation
Choice A rationale
Appendicitis is the leading cause of emergency abdominal surgeries, accounting for a significant percentage globally. It results from inflammation of the appendix, often due to obstruction by fecalith or lymphoid hyperplasia. This condition progresses to localized infection, abscess formation, and potential rupture, requiring urgent surgical intervention to prevent life-threatening complications.
Choice B rationale
The assertion that appendicitis is not the most common reason for emergency abdominal surgery contradicts epidemiological data. Diseases like cholecystitis or bowel obstructions occur less frequently and often have alternate non-surgical management options. Appendicitis’s acute presentation and high risk of complications necessitate surgery, maintaining its predominance in emergency settings.
