The patient is a composite written for a model paper.
Subjective
Mr. J., a 71-year-old retired shipyard welder, reports three weeks of increasing shortness of breath, now after one flight of stairs, with a nonproductive cough and an aching discomfort low on the right side of his chest. He sleeps on two pillows, unchanged from before. He denies fever, hemoptysis or leg swelling. He has lost 4 kg without trying over two months. History: hypertension, a 40-pack-year smoking history, quit 10 years ago. He worked around asbestos insulation in the shipyard for 20 years. Medications: lisinopril 20 mg daily. No allergies.
Objective
Vital signs: temperature 37.0 °C, blood pressure 136/80 mm Hg, pulse 92 and regular, respiratory rate 22, oxygen saturation 93% on room air.
General: thin man, speaking in full sentences, mildly short of breath.
Neck: jugular venous pressure 7 cm above the sternal angle, not elevated; no lymphadenopathy.
Chest inspection: reduced expansion on the right with deep breathing; no scars or deformity.
Palpation: tactile fremitus reduced over the right lower posterior chest to the level of the eighth rib; normal on the left.
Percussion: stony dullness over the right posterior base up to the eighth rib; resonant elsewhere.
Auscultation: breath sounds absent at the right base, with bronchial breath sounds and egophony just above the dull area; no crackles, wheezes or friction rub.
Cardiovascular: apical impulse in its normal position, not displaced laterally or downward. S1 and S2 normal; no S3, S4 or murmur. No peripheral edema. Radial and pedal pulses intact.
Extremities: mild clubbing of the fingers.
Assessment
Right pleural effusion, moderate, unilateral, with weight loss, clubbing and asbestos and smoking exposure; heart failure unlikely on examination. Differential includes malignancy, including mesothelioma or lung cancer, parapneumonic effusion and, less likely, heart failure.
Plan
Chest radiograph today, with point-of-care or formal ultrasound to confirm and estimate size. Referral for diagnostic thoracentesis with pleural fluid analysis: protein, lactate dehydrogenase, cell count, glucose, pH, cytology and cultures, with simultaneous serum protein and lactate dehydrogenase. CT of the chest after drainage. Return immediately if breathing worsens.
The examination cannot name the cause of the fluid, but it can decide how quickly someone must find out.
Why the Percussion Finding Carries Weight
Physical examination maneuvers vary in their accuracy for pleural effusion. Wong et al. (2009) systematically reviewed five prospective studies involving 934 patients and found that dullness to conventional percussion was the most accurate finding, with a summary positive likelihood ratio of 8.7, while the absence of reduced tactile fremitus made an effusion less likely, with a negative likelihood ratio of 0.21. Mr. J.'s combination of dullness and reduced fremitus therefore makes an effusion likely enough that imaging is to confirm it rather than to look for it.
Why Breath Sounds and Egophony Change at the Edge
Fluid in the pleural space separates the lung from the chest wall, so sound transmits poorly and breath sounds are absent over the fluid. Just above it, the compressed lung transmits sound better, producing bronchial breath sounds and egophony. These findings help locate the upper edge of the fluid.
What the Heart Examination Adds
Heart failure is the most common cause of pleural effusion overall and usually causes bilateral effusions, often larger on the right (Light, 2002). Mr. J.'s normal jugular venous pressure, absent S3, nondisplaced apical impulse, absence of edema and unchanged orthopnea argue against heart failure. A unilateral effusion without signs of heart failure calls for fluid analysis.
Why the Fluid Must Be Tested
Light et al. (1972) established criteria that classify an effusion as an exudate if the ratio of pleural fluid to serum protein exceeds 0.5, the ratio of pleural fluid to serum lactate dehydrogenase exceeds 0.6, or pleural fluid lactate dehydrogenase is above two-thirds of the laboratory's upper normal value for serum. Transudates usually reflect systemic causes such as heart failure; exudates suggest local disease such as infection or cancer. Light (2002) recommends diagnostic thoracentesis for new effusions of uncertain cause.
Why the History Raises Concern
Weight loss, clubbing, a long smoking history and heavy asbestos exposure make malignancy, including mesothelioma and lung cancer, important to exclude. Parapneumonic effusion is less likely without fever but remains possible.
Order of the Examination
The examination followed inspection, palpation, percussion and auscultation for the chest, with the posterior chest examined with Mr. J. sitting upright and arms folded forward to separate the scapulae. Comparing side to side at each level is the key to detecting a unilateral finding, and the examination moved from top to bottom on alternating sides rather than completing one side first. For the heart, the jugular venous pressure was measured with his trunk raised to about 45 degrees, and the apical impulse palpated with the patient supine and then turned slightly to the left.
What Would Change the Assessment
Findings that would have pointed toward heart failure include a raised jugular venous pressure, an S3, a displaced apical impulse, bilateral crackles and leg edema. Fever, productive cough and crackles above the effusion would point toward a parapneumonic effusion. A tracheal shift away from the effusion would suggest a large effusion needing urgent drainage; Mr. J.'s trachea is midline.
Occupational History as Clinical Data
The occupational history is as important as any examination finding here. Asbestos exposure decades earlier is the main risk factor for mesothelioma, which commonly presents with a unilateral effusion and chest wall pain, and it also increases the risk of lung cancer, especially in smokers. Recording the years and type of exposure in the note ensures that the pathologist and pulmonologist interpret the fluid and imaging with this risk in mind.
Documentation Notes
Recording the level of dullness by rib, the side and the associated findings allows the next clinician to judge whether the effusion is growing. Documenting the negative cardiac findings explains why heart failure was not assumed.
Safety Before Discharge From the Clinic
With oxygen saturation of 93% and a respiratory rate of 22, Mr. J. is stable for outpatient imaging today but not for a delay of days. I arranged same-day radiography and a next-day thoracentesis appointment, and gave him clear instructions to go to the emergency department if his breathing worsens, he develops chest pain or his lips turn blue.
What the Chest Radiograph Should Show
On an upright film, a moderate effusion blunts the costophrenic angle and forms a meniscus rising along the lateral chest wall; the level should match the dullness mapped by percussion, which is a check on the examination itself.
Conclusion
Mr. J.'s examination shows a right pleural effusion, with percussion dullness and reduced fremitus, the most accurate bedside findings, and a cardiac examination that argues against heart failure. With weight loss, clubbing and asbestos and smoking exposure, the unilateral effusion requires imaging, thoracentesis and analysis by Light's criteria to find its cause.

How this NRP 531 Week 4 example is structured
The NRP/531 Week 4 work usually asks for a cardiovascular and respiratory examination write-up. This paper records inspection, palpation, percussion and auscultation in order, cites the diagnostic accuracy of the key maneuvers and shows how the cardiac and respiratory findings together narrow the differential. Students search this week as NRP 531 Week 4, NRP531 Wk 4 or NRP/531 Wk 4; all three are the same assignment.
NRP/531 Week 4 questions, answered
What does NRP/531 Week 4 usually ask for?
Many sections ask students to document a cardiovascular and respiratory examination and interpret the findings.
Which examination findings best detect a pleural effusion?
A systematic review found dullness to percussion was the most accurate finding for detecting pleural effusion, and normal tactile fremitus made an effusion less likely.
What are Light's criteria?
Criteria comparing pleural fluid and serum protein and lactate dehydrogenase to classify an effusion as a transudate, often from heart failure, or an exudate, from causes such as infection or cancer.
