Skin: Fair complexion, normal turgor, no lesions
HEENT: Pupils equal, round, and reactive, extra ocular eye muscles intact
Nose and throat clear, tympanic membranes clear
Mucous membranes pink and moist
Supple with no obvious nodes or bruits, normal thyroid, no jugular vein distention
Cardiac: Rapid but regular rate, no murmur, gallops, or rubs
Chest: Subnormal diaphragmatic excursion, no wheezing or crackles
Abdomen: Soft with + bowel sounds, non-tender and non-distended, no hepatomegaly or splenomegaly
Breasts: Normal with no lumps
Gen/Rectal: Heme negative stool
Extremities: Prominent saphenous vein in left leg with multiple varicosities visible bilaterally, peripheral pulses + 1 bilaterally, no cyanosis or clubbing, or edema
Strength throughout is equal, boot feet cool to the touch
Neurological: Alert and oriented X 3, cranial nerves II-XII intact, deep tendon patellar reflexes 2+
ECHO: Ventricular wall movements within normal limits
V/Q Scan: Peripheral defect at right base. Some mismatch between perfusion abnormality and ventilation of the right lung, suggesting an intermediate probability for pulmonary embolus
Lower extremity venous duplex u/s: Both right and left extremities show abnormal of venous narrowing, prominent collateral vessels, and incompressibility of the deep venous system in the popliteal veins. These findings are consistent with bilateral DVT.
Pulmonary angiogram: Abrupt arterial cutoff in peripheral vessel in right base
1. What clinical manifestations, if any, suggest a pulmonary embolus in the is patient?
2. Identify five major risk factors for pulmonary thromboembolism.
3. Why do you think the patient is taking amitriptyline every evening?
4. Why is this patient taking metoclopramide every evening?
5. What condition does this patient have that is causing her to take ibuprofen for cramps?
6. Are any of the patient’s vital signs consistent with pulmonary thromboembolism?
7. Is this patient technically considered underweight, overweight, or obese or normal/ healthy? What is her BMI?
8. If you had noticed jugular vein distention what is a reasonable explanation?
9. Are any of the patient’s laboratory blood tests significantly abnormal? Provide a reasonable explanation for each abnormal test.
10. What might the patient’s chest x-ray show if it were taken now?
11. What does the EKG strip provided show?
12. Which single clinical finding provides the strongest evidence for pulmonary embolus in this patient?
13. Which is a more appropriate duration of treatment with warfarin in this patient: 3 months, 6 months, or long-term anticoagulation?
14. Is the use of a thrombolytic agent in this patient advisable?
15. Would you suspect that the is patient’s plasma D-dimer concentration is negative or elevated? Why?
16. Is massive pulmonary thromboembolism an appropriate diagnosis in this patient?
17. What is a likely cause of respiratory alkalosis in this patient?
18. Areas of ischemia in the lung from a pulmonary embolus usually become hemorrhagic. The patient’s chest x-ray is below, she presented with chest pain, hypoxia and lower limb DVT. Where is the hemorrhagic area? Upper right lung? Lower right lung? Upper left lung? Or lower left lung?
19. In terms of thrombus development, what is the fundamental difference between warfarin or alteplase?
