What are some of the environmental factors that can influence the psychosocial changes in older adults?

The correct answer isA, D, and E.

Here is why:.

A. Elevated white blood cell count.

This is a sign of infection and inflammation in the body, which can be caused by a UTI.An elevated white blood cell count can also indicate a complication of UTI such as pyelonephritis (kidney infection) or sepsis (blood infection).

D. Altered mental status.

This is a common symptom of UTI in older adults, especially those with dementia or other cognitive impairments.UTIs can cause confusion, agitation, delirium, or behavioral changes in the elderly due to the effects of infection and inflammation on the brain.

E. Positive urine culture.

This is the definitive test to diagnose a UTI, as it identifies the type and number of bacteria present in the urine.A positive urine culture confirms the presence of a UTI and guides the appropriate antimicrobial treatment.

The other choices are wrong because:.

•.

B. Decreased serum creatinine level.

This is not a sign of UTI or its complications.

Serum creatinine is a measure of kidney function, and it usually increases when the kidneys are damaged or impaired.A decreased serum creatinine level may indicate other conditions such as liver disease, muscle wasting, or malnutrition.

•.

C. Increased urine specific gravity.

This is not a sign of UTI or its complications.

Urine specific gravity is a measure of urine concentration, and it usually increases when the body is dehydrated or has high levels of solutes in the urine.An increased urine specific gravity may indicate other conditions such as diabetes mellitus, heart failure, or dehydration.

Normal ranges for some of these tests are:.

• White blood cell count: 4,000 to 11,000 cells per microliter (mcL) of blood.

• Serum creatinine: 0.6 to 1.2 milligrams per deciliter (mg/dL) for men and 0.5 to 1.1 mg/dL for women.

• Urine specific gravity: 1.005 to 1.030.

The correct answer is A.“Do you drive your own car or use public transportation?.” This question is appropriate for the domain ofmode of transportation, which is one of the eight areas of occupational performance assessed by the Lawton Instrumental Activities of Daily Living (IADLs) Scale.The scale evaluates a person’s ability to engage in more complex activities thought necessary for functioning in community settings.

Choice B is wrong because it is not related to the domain of mode of transportation, but rather to the domain ofability to use a telephone.The scale asks about the person’s ability to operate a telephone, dial numbers, and answer calls.

Choice C is wrong because it is not related to the domain of mode of transportation, but rather to the domain ofshopping.The scale asks about the person’s ability to take care of all shopping needs independently, shop for small purchases, or need assistance with shopping.

Choice D is wrong because it is not related to the domain of mode of transportation, but rather to the domain ofmobility.The scale does not assess mobility directly, but it may be inferred from the person’s ability to travel by public transportation or car.

The Lawton IADLs Scale has a summary score that ranges from 0 (low function, dependent) to 8 (high function, independent) for women, and 0 to 5 for men.The score identifies areas of need in regard to care and support.
