## Question

A 58-year-old client (72 kg) is 4 hours after an abdominal hysterectomy. Preoperative hemoglobin was 10.2 g/dL. She received 1,500 mL of lactated Ringer's in surgery and her last opioid dose was 4 hours ago. The nurse reviews the following findings. Which findings require immediate follow-up? Select all that apply.

1BP 134/72 mm Hg at 1 hour and 128/84 mm Hg at 4 hours.
2Hemoglobin 9.8 g/dL on the postoperative 3-hour sample.
3Restless, repeatedly asks what time it is, and picks at sheets.
4Incision pain 6/10 with guarding; opioid due now as ordered.
5Urine output 60 mL, 40 mL, then 22 mL over the last 3 hours.
6Heart rate 84/min, 96/min, then 108/min over the last 3 hours.
7Dressing has a 3 cm serosanguineous spot unchanged since arrival.
8Temperature 37.9 C (100.2 F) with slightly diminished basal sounds.

## Explanation

The steadily rising heart rate, pulse pressure narrowing from 62 to 44 mm Hg, urine output falling to 22 mL/h (about 0.3 mL/kg/h), and new restlessness form a compensated-hypovolemia pattern that points to concealed bleeding. Hemoglobin 9.8 g/dL is close to her preoperative anemia and diluted by crystalloid, and it lags behind acute blood loss. The pain, unchanged dressing spot, and low-grade temperature each have a documented expected explanation.

## In-depth explanation

Quick answer
Findings 1, 3, 5, and 6 require immediate follow-up.

Why this is correct
Early hemorrhage is compensated: vasoconstriction keeps systolic pressure near normal while heart rate climbs and diastolic pressure rises, so pulse pressure narrows (62 to 44 mm Hg). Kidney perfusion falls first, dropping urine output from 60 to 22 mL/h, below 0.5 mL/kg/h for a 72-kg client. New restlessness and disorientation reflect reduced cerebral perfusion. Together the trends matter more than any single value, and bleeding after hysterectomy is often intra-abdominal with a dry dressing.

Easy analogy or mental picture
Compensated bleeding is like a company losing money while the accountant keeps the headline profit steady: the details (heart rate, pulse pressure, urine) show the loss before the top number (systolic BP) does.

Memory hook
Trends beat snapshots: pulse up, pulse pressure squeezed, pee down, mind restless = bleeding until proven otherwise.

NCLEX decision rule
When evaluating postoperative findings, compare each value with its trend and with the documented explanation; findings with an expected cause are lower priority than a cluster pointing to hypovolemia.

Why the other choices are wrong
Hemoglobin 9.8 g/dL (option 2): tempting because it is low, but it is near her preoperative 10.2 g/dL, diluted by 1,500 mL of crystalloid, and hemoglobin lags behind acute bleeding. Pain 6/10 (option 4): pain can raise heart rate, but her analgesic is simply due; pain does not explain falling urine output or restlessness. Dressing spot (option 7): unchanged serosanguineous drainage is expected and does not exclude internal bleeding. Temperature 37.9 C (option 8): low-grade temperature with diminished basal sounds in the first 24 hours is usually inflammatory or atelectasis-related, not hemorrhage.

## Clinical scenario

Scenario
A client 4 hours after abdominal hysterectomy has a rising heart rate, narrowing pulse pressure, falling urine output, and new restlessness, while her dressing looks unchanged.

## Key concepts

- **Pulse pressure** — Systolic minus diastolic pressure; it narrows early in hemorrhage as vasoconstriction raises diastolic pressure.
- **Compensated shock** — The stage in which the body maintains blood pressure through tachycardia and vasoconstriction despite losing volume.
- **Oliguria** — Urine output below about 0.5 mL/kg/h, an early sign of reduced kidney perfusion.
