A nurse reads in a client chart that the client is 92 years old. According to the US. Census Bureau, the nurse knows that the client is classified as what stage of older adulthood?
very Old
Aged
Older
Elderly
The Correct Answer is A
A. Very old (sometimes referred to as the "oldest-old") typically includes individuals 85 years and older, according to classifications used by the U.S. Census Bureau and gerontological studies. A 92-year-old falls into this category.
B. Aged is a general term and not an official classification. It may be used broadly but doesn't specifically apply to the 85+ group.
C. Older is a nonspecific term often used to describe those over 65 but is not a distinct age category like “very old.”
D. Elderly is another broad, non-specific term and is often used interchangeably with “older adults,” but does not denote a specific age group such as the "very old" classification.

Correct Answer is B
Explanation
A. Slowing carbohydrate absorption in the small intestine is the primary action of alpha-glucosidase inhibitors, not metformin.
B. Reducing glucose production by the liver and enhancing insulin sensitivity accurately describes metformin’s mechanism. It lowers hepatic glucose output and improves peripheral uptake of glucose, making it the first-line treatment for type 2 diabetes.
C. Increasing insulin production from the pancreas is the action of sulfonylureas, not metformin. Metformin does not stimulate insulin secretion.
D. Increasing insulin release, inhibiting glucagon, and delaying gastric emptying describes the action of GLP-1 receptor agonists, not metformin.
Correct Answer is A
Explanation
A. Recent use of antibiotics is the greatest risk factor for developing C. difficile infection. Antibiotics disrupt the normal gut flora, allowing C. difficile to overgrow and produce toxins that cause severe diarrhea and colitis.
B. Prolonged rehabilitation stays can increase exposure to hospital-acquired infections but are not as strongly associated with C. difficile as antibiotic use.
C. Staying in the ICU can increase the risk for various infections, but it’s the antibiotic use commonly associated with ICU care that elevates C. difficile risk—not the ICU stay itself.
D. Recent surgery may raise infection risk in general, but it is not as specifically linked to C. difficile as antibiotic therapy is.
