Answer and Explanation

The Correct Answer is A

A. Stable angina is characterized by chest pain or discomfort that occurs with physical exertion or stress and is relieved with rest or nitroglycerin.

B. Pulmonary embolus typically causes sudden shortness of breath, chest pain, and possible hemoptysis, but not a pattern that resolves with rest or cessation of activity.

C. Myocardial infarction (MI) typically causes prolonged chest pain that does not resolve quickly and is not relieved by rest.

D. Unstable angina is more severe than stable angina, occurring at rest or with minimal activity, and does not resolve quickly. It also increases in frequency and intensity over time.

Correct Answer is A

Explanation

A. In post-streptococcal glomerulonephritis, the immune response to strep infection results in inflammatory changes in the glomeruli, making the capillaries "leaky." This allows protein and red blood cells to pass into the urine, causing proteinuria and hematuria.

B. Post-streptococcal glomerulonephritis is not characterized by an autoantibody attack on the renal artery. It is primarily an immune-mediated inflammatory response in the glomeruli.

C. While casts may appear in the urine, the primary issue is glomerular capillary inflammation and permeability rather than direct leaking of casts.

D. Post-streptococcal glomerulonephritis typically results in a decreased GFR due to inflammation and reduced kidney function, not an increase.

A. Varicose veins. B. Thick green sputum. C. Hypertension. D. Sudden dyspnea.

Correct Answer is D

Explanation

A. While varicose veins can be a risk factor for deep vein thrombosis (DVT), which in turn can lead to a PE, they are not an acute symptom of a PE.

B. Thick green sputum is more indicative of a respiratory infection, such as pneumonia, rather than a pulmonary embolus.

C. Hypertension can be seen in various conditions but is not a primary indicator of PE.

D. Sudden dyspnea (difficulty breathing) is a classic sign of a pulmonary embolus, as the clot obstructs blood flow to the lungs, leading to respiratory distress.
