The nurse recognizes that a patient with sepsis is at risk to develop hypotension. Which pathophysiological process is responsible for this symptom?
Vasodilation and fluid shift out of the vascular space
Platelet aggregation and thrombus formation
Decreased blood glucose and oliguria
Hypoxemia and anaerobic metabolism
The Correct Answer is A
Choice A reason: In sepsis, inflammatory mediators cause vasodilation and increased capillary permeability, leading to fluid leaking out of the vascular space, resulting in hypotension.
Choice B reason: Platelet aggregation and thrombus formation can occur in sepsis but are more related to disseminated intravascular coagulation (DIC) rather than directly causing hypotension.
Choice C reason: Decreased blood glucose and oliguria can be consequences of sepsis but are not the primary pathophysiological processes responsible for hypotension.
Choice D reason: Hypoxemia and anaerobic metabolism may result from the effects of sepsis on the body, including hypotension, but they are not the direct cause of hypotension.

Correct Answer is D
Explanation
The correct answer is d. Urine output 60 mL.
Choice A reason: A pulse oximetry reading of 96% is within normal limits and does not indicate an ineffective response to the medications.
Choice B reason: A heart rate of 77, regular, is also within normal limits and does not suggest an ineffective response.
Choice C reason: Trace bilateral ankle edema may persist even after effective treatment due to residual effects of heart failure.
Choice D reason: A urine output of 60 mL over 2 hours post-diuretic administration suggests an inadequate response, as furosemide is expected to produce a significant diuresis to reduce fluid overload in acute heart failure.
Correct Answer is C
Explanation
Choice A reason: An oral temperature of 99.8°F (37.7°C) post-operatively may not be unusual and does not necessarily indicate a complication.
Choice B reason: A post-operative hemoglobin of 10.9 g/dL is slightly below the normal range but may be expected after surgery due to blood loss.
Choice C reason: A client reporting a pressure sensation at the incision site could indicate bleeding or swelling under the incision, which can be a sign of a hematoma, a serious complication that needs immediate attention.
Choice D reason: Pain at the incision site is expected post-operatively and can be managed with pain relief measures.
