The nurse determines that a patient is experiencing oliguria based on which amount of urinary output?
uOP of 350 ml/day
uOP of 450 ml/day
uOP of 550 ml/day
uOP of 650 ml/day
The Correct Answer is A
Choice A reason: Oliguria is defined as a significantly reduced urine output, typically less than 400-500 ml per day in adults. A urinary output of 350 ml/day falls well below this threshold, indicating a condition of oliguria. This reduced output can be a sign of underlying issues such as dehydration, renal failure, or urinary tract obstructions. It is essential for healthcare providers to identify and address the cause of oliguria to prevent further complications.
Choice B reason: A urinary output of 450 ml/day is also indicative of oliguria but is closer to the higher end of the threshold for this condition. However, the specified definition usually considers less than 400 ml/day as oliguria, making 350 ml/day a more definitive example. While 450 ml/day is still reduced and warrants attention, it is slightly above the typical clinical cutoff for oliguria.
Choice C reason: A urinary output of 550 ml/day is above the typical threshold for oliguria. It indicates reduced urine output but does not meet the clinical definition of oliguria. Such output may still require monitoring, but it does not classify as oliguria, which is generally defined as less than 400-500 ml per day.
Choice D reason: A urinary output of 650 ml/day is well above the threshold for oliguria. This output is closer to normal daily urine output, which typically ranges from 800 to 2000 ml/day, depending on fluid intake and other factors. Therefore, it does not indicate oliguria and would be considered within normal limits or slightly reduced, depending on the clinical context.

Correct Answer is D
Explanation
Choice A reason: Assessing bowel sounds is important for postoperative care, especially after abdominal surgery, but it is not the immediate priority upon admission from the PACU.
Choice B reason: Monitoring temperature is essential to detect signs of infection or other complications, but it is not the immediate priority right after surgery.
Choice C reason: Checking the surgical dressing for bleeding or signs of infection is important, but maintaining adequate oxygen saturation takes precedence immediately post-surgery.
Choice D reason: Oxygen saturation is the priority assessment because it ensures that the patient is receiving adequate oxygenation after surgery. Respiratory complications are common postoperatively, and ensuring proper oxygenation is crucial for patient safety.
Correct Answer is A
Explanation
Choice A reason: The mouth serves as the portal of entry for hepatitis A when the virus is ingested through contaminated food or water. The portal of entry is the site through which the pathogen enters the body to initiate infection. In this case, consuming contaminated food allows the hepatitis A virus to enter the body through the mouth, leading to infection.
Choice B reason: The infectious agent is the pathogen responsible for causing the disease. In this scenario, the hepatitis A virus is the infectious agent. However, the question asks about the portal of entry, which is the mouth, not the infectious agent itself.
Choice C reason: A susceptible host is an individual who is vulnerable to infection due to factors like a weakened immune system or lack of prior immunity. While the client in the question is a susceptible host, the specific answer to the question is about the portal of entry, which is the mouth.
Choice D reason: The reservoir is the natural habitat or environment in which the pathogen lives and multiplies. For hepatitis A, common reservoirs include contaminated food and water. The reservoir is not the focus of this question; rather, it is asking about the portal of entry, which is the mouth.
