The nurse is reviewing the laboratory results of an older adult client who has a urinary tract infection (UTI).
Which of the following findings should alert the nurse to a possible complication of UTI in older adults?
(Select all that apply.).
Elevated white blood cell count.
Decreased serum creatinine level.
Increased urine specific gravity.
Altered mental status.
Positive urine culture.
Correct Answer : A,D,E
The correct answer is A, 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 .

Correct Answer is C
Explanation
The correct answer is C.
Check for bladder distention or fecal impaction.
Autonomic dysreflexia is a disorder of autonomic nervous system dysregulation that occurs in patients with a spinal cord injury above T6.
It is caused by an exaggerated reflex response of the sympathetic nervous system due to an irritating stimulus below the spinal cord injury.It leads to severe hypertension and is a medical emergency.
Bladder or bowel distension are the most common triggers of autonomic dysreflexia.
Therefore, the priority nursing intervention is to check for bladder distention or fecal impaction and relieve them as soon as possible.
This can help to eliminate the stimulus and lower the blood pressure.
Choice A is wrong because administering antihypertensive medication as prescribed may not be effective or appropriate for autonomic dysreflexia.
The hypertension is caused by a reflex mechanism and not by a primary cardiovascular disorder.Moreover, antihypertensive drugs may cause hypotension once the stimulus is removed.
Choice B is wrong because elevating the head of bed to 90 degrees may not be enough to lower the blood pressure.It may also increase the risk of orthostatic hypotension once the stimulus is removed.However, sitting the patient upright and loosening any tight clothing are recommended as initial steps to reduce the blood pressure.
Choice D is wrong because applying a cooling blanket to lower body temperature is not indicated for autonomic dysreflexia.There is no evidence that body temperature is elevated or contributes to the hypertension in this condition.A cooling blanket may also cause vasoconstriction and worsen the hypertension.
Normal ranges for blood pressure vary depending on age, sex, and other factors.
However, a general guideline is that systolic blood pressure should be less than 120 mm Hg and diastolic blood pressure should be less than 80 mm Hg for most adults.
Normal ranges for heart rate also vary depending on age, activity level, and other factors.
However, a general guideline is that resting heart rate should be between 60 and 100 beats per minute for most adults.

Correct Answer is D
Explanation
The correct answer isD.
All of the above.All of these findings are risk factors for falls in older adults, according to the literature.
Some explanations for why each choice is a risk factor are:.
A. Orthostatic hypotension: This is a condition where blood pressure drops too much when getting up from lying down or sitting, causing dizziness, lightheadedness, or fainting.This can affect balance and increase the chance of falling.
B. Urinary frequency: This is a condition where one needs to urinate often, sometimes urgently.This can cause rushed movement to the bathroom, especially at night, which can lead to tripping, slipping, or losing balance.
C. Visual impairment: This is a condition where one has reduced or distorted vision, such as due to cataracts, glaucoma, macular degeneration, or diabetic retinopathy.This can affect depth perception, contrast sensitivity, and ability to detect obstacles or hazards in the environment.
Some normal ranges for these conditions are:.
• Orthostatic hypotension: A normal blood pressure change when standing up is less than 20 mmHg systolic (top number) or 10 mmHg diastolic (bottom number).
Orthostatic hypotension is defined as a drop of at least 20 mmHg systolic or 10 mmHg diastolic within 3 minutes of standing.
• Urinary frequency: A normal urinary frequency is about 4 to 6 times per day, depending on fluid intake and other factors.
Urinary frequency is considered abnormal if it is more than 8 times per day or more than 2 times per night.
• Visual impairment: A normal visual acuity is 20/20 or better with or without correction.
Visual impairment is defined as a visual acuity of 20/40 or worse in the better-seeing eye with best correction possible.
