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
Explanation
Choice A rationale
A bland diet reduces gastric irritation by avoiding substances that stimulate acid secretion or exacerbate nausea. It includes foods like rice, bananas, and toast that are easy to digest and less likely to provoke symptoms of nausea or vomiting.
Choice B rationale
Opposing the bland diet recommendation for severe nausea ignores scientific evidence that supports its use. Providing a diet rich in spices or acidic foods can worsen symptoms by irritating the gastrointestinal tract further. .
Correct Answer is A
Explanation
Choice A rationale
Contact isolation prevents the transmission of Clostridium difficile spores, a significant source of nosocomial infections. Private rooms reduce cross-contamination risks.
Choice B rationale
Antidiarrheal use is contraindicated in Clostridium difficile infection as it may worsen colitis by retaining toxins. Prompt stool elimination is vital.
Choice C rationale
Antibiotics are used to treat Clostridium difficile but educating the patient about antibiotic cessation is inappropriate as their use is essential for infection control.
Choice D rationale
Stool softeners are unnecessary since diarrhea is already present, and further softening may exacerbate fluid and electrolyte loss.
