Your heart failure patient has gained 2.2 kg since admission three days ago, with tighter ankle swelling. This suggests:

Roughly 2 litres of fluid retention: decompensation needing medical review

A faulty set of scales, most likely

For daily weights to be meaningful, they must be:

Same scales, same time of day (usually morning after voiding), similar clothing, recorded on the chart

Taken whenever convenient on any available scales

Estimated when the patient is tired

The patient becomes breathless lying flat and asks for help at 2am, gasping. You recognise:

Orthopnoea and paroxysmal nocturnal dyspnoea: worsening heart failure, so sit them up, obs and NEWS2, escalate

A nightmare needing reassurance only

After a furosemide dose, your monitoring includes:

Urine output on the balance chart, blood pressure, dizziness on standing, and the weight trend

Nothing; diuretics are self-monitoring

Only asking if they feel better

Doubling the next dose if output seems low

Which discharge education belongs in this scenario's Evaluation phase?

Daily self-weighing with a 'call your team if you gain about 2 kg in a few days' rule, fluid and salt advice per their plan, and symptom red flags

Stop tablets when ankles look thinner

Drink extra fluids to flush the kidneys

Avoid weighing at home to reduce anxiety

The heart failure scenario flips the usual fluid logic: in most stations fluid is the treatment, here it’s the threat. The marks follow whether your assessment, charts and education all point at the same idea: track the fluid, and act on the trend.

Assessment. The pattern questions first: breathlessness on exertion, lying flat (orthopnoea; ask how many pillows), waking at night gasping (paroxysmal nocturnal dyspnoea). Then the fluid map: ankle and leg oedema (how far up), abdominal tightness, weight against their usual, urine output. Full observations and NEWS2; saturations and respiratory rate carry the pulmonary-oedema warning. Medication history matters here: diuretics, and whether they’ve been taken.

Planning. Priorities: breathing and oxygenation, fluid management, then mobility, skin (oedematous legs mark easily) and education. Goals in numbers: weight trending down towards their dry weight, breathless episodes reducing, obs in range, skin intact.

Implementation. The heart failure nursing set:

Daily weights done properly: same scales, same morning time after voiding, similar clothing, charted. The trend is the whole point.
Fluid balance chart (the bedside skill), plus any prescribed fluid restriction explained kindly; restriction fails when the patient doesn’t know why.
Upright positioning for breathlessness; oxygen only as prescribed to target.
Prescribed diuretics on time, with the monitoring that follows them: output, blood pressure, postural dizziness.
Pressure care for oedematous skin, and mobility as tolerated.

Evaluation. Read the trends together: weight falling towards baseline, oedema receding, sleeping flatter, NEWS2 quiet, walking further. Then convert the ward routine into a home routine, because this scenario’s discharge teaching is standard and marked: daily self-weighing with an action threshold (around 2 kg gained over a few days means call the team), the fluid plan, medication adherence, and the red flags that skip the routine and go straight to help: worsening breathlessness at rest, chest pain, gasping at night.

Five questions below, then the community diabetes scenario, the exam’s main home-setting station.

Key takeaway from OSCE APIE Scenario: Chronic Heart Failure

Frequently asked questions

Why are daily weights central in heart failure?

Short-term weight change tracks fluid, and heart failure's danger is fluid accumulating in lungs and tissues. A gain of around 2 kg over a few days signals decompensation and drives diuretic decisions, so the weighing routine has to be consistent to mean anything.

What breathlessness pattern belongs to heart failure?

Worse lying flat (orthopnoea, counted in pillows needed) and waking at night gasping (paroxysmal nocturnal dyspnoea), alongside exertional breathlessness and ankle swelling that worsens through the day.

What does diuretic monitoring involve for the nurse?

Fluid balance and urine output after doses, daily weight trend, blood pressure (diuretics drop it), dizziness on standing, and awareness that bloods for kidney function and potassium are being monitored medically.

5questions. Click an answer to see the explanation. Your score is saved on this device only.

1
Your heart failure patient has gained 2.2 kg since admission three days ago, with tighter ankle swelling. This suggests:
Short-term weight is fluid: about 1 kg per litre. A 2 kg climb with worsening oedema is the decompensation pattern the daily-weight routine exists to catch, and it feeds a diuretic review rather than quiet documentation.
2
For daily weights to be meaningful, they must be:
The trend is the data, and the trend only exists if the method is constant. Morning, post-void, same scales, similar clothes. An estimated or inconsistent weight quietly poisons the numbers that dosing decisions sit on.
3
The patient becomes breathless lying flat and asks for help at 2am, gasping. You recognise:
Flat-position breathlessness and night-time gasping episodes are the classic left-sided failure pattern. Upright positioning helps immediately; the observations and escalation decide what happens next. Naming the terms shows the examiner the recognition happened.
4
After a furosemide dose, your monitoring includes:
Diuretics work through urine output (chart it), drop blood pressure (measure it, and warn about standing slowly), and their effect shows in tomorrow's weight. Dose changes belong to the prescriber, informed by exactly the numbers you're keeping.
5
Which discharge education belongs in this scenario's Evaluation phase?
Self-monitoring is the evidence-backed heart failure habit: daily weights with a clear action threshold, adherence to the fluid plan, and knowing the deterioration signs. The wrong options invert the condition's logic, which is exactly how the exam writes distractors.
