Match the term with the correct definition:

Choice A rationale

Blood pressure of 85/55 indicates hypotension, which can compromise perfusion to vital organs such as the brain and kidneys. Immediate assessment is necessary to determine the underlying cause, such as dehydration or internal bleeding.

Choice B rationale

Hemoglobin level of 7 g/dL is critically low, falling below the normal range of 12–16 g/dL for women or 13–18 g/dL for men. This reflects severe anemia, which may require urgent intervention, including blood transfusion or addressing the cause of anemia.

Choice C rationale

Massive bleeding from the right lower leg is an emergency due to the risk of hypovolemic shock and significant blood loss. Stabilization of the bleeding site and monitoring for signs of systemic impact is required immediately.

Choice D rationale

A temperature of 96.5°F (35.8°C) may signal mild hypothermia or a systemic condition. While it requires follow-up, it is not as immediately life-threatening as the other findings and therefore does not warrant immediate prioritization.

Choice A rationale

Loss of sensation to the perineum, buttocks, inner thighs, and back of the legs may indicate cauda equina syndrome, a surgical emergency. This condition involves compression of the spinal nerve roots and can lead to permanent neurological damage if not promptly addressed. Immediate medical intervention is critical.

Choice B rationale

Nausea and delayed voiding postoperatively are common, potentially due to anesthesia effects or limited mobility. While these findings warrant monitoring, they do not typically indicate an urgent issue unless prolonged or associated with other complications.

Choice C rationale

Mild low back pain is expected after lumbar spinal surgery due to manipulation of spinal structures. Pain management with prescribed analgesics and gradual mobilization is part of the standard postoperative care plan, and it does not usually necessitate immediate reporting.

Choice D rationale

A single episode of emesis can result from anesthesia effects or medication. Unless accompanied by persistent vomiting, signs of aspiration, or electrolyte imbalances, isolated emesis is not typically urgent and should be managed with antiemetics if necessary.
