Answer. E
Key Concepts : Recognize the definition of “Recurrent” UTI . Recognize the difference between “colonization” and “Active Infection”
Answer. E No need of treatment is the correct choice because this old man has no signs of active infection at this time. He has no fever or tachycardia or any signs of sepsis or infection.
Ans. A is incorrect. Cystoscopy and IVP can be performed to evaluate the urinary tract if the patient had severe UTI or recurrent UTI. It is not the appropriate step at this time.
Ans. B would be appropriate as a prophylactic therapy if the patient has Recurrent UTI. Understand that the Recurrent UTI is defined as 2 or more episodes in past 6 months or 3 or more episodes in past one year. This patient does not meet the criteria of recurrent UTI since he suffers only one episode every 6 months.
Ans. C is not helpful in preventing UTI and is also, not appropriate step at this time. Indwelling catheters may in fact, increase the risk of UTIs.
Ans. D would be appropriate if the patient had severe UTI. He has no signs of acute infection at this time.
EEEEEEEEEEEEEE
AS THIS NURSE HAS NO OTHER WORK SHE SHOULD FOLLOW ORDERS
The answer is B
No single definition of the frequency of recurrent urinary tract infection (UTI) exists. A pragmatic definition is 3 or more per year.
answer :E
asymptomatic bacteruria – just observe.
100,000 colonies is enough to investigate further. its possible that it could be caused by BPH. Do a rectal for bph then treat the underlying cause.
E, no need to treat asymptomatic pt of UTI, except pregnancy
