A patient, who is on complete bed rest following extensive surgery, begins to complain of chest pain and shortness of breath with hemoptysis.
His SO2 measures 90%. The nurse recognizes that the patient is most likely exhibiting signs and symptoms of which condition?
Deep vein thrombosis (DVT).
Pulmonary embolus (PE).
Anemia.
Right heart failure (RHF).
The Correct Answer is B
Choice A rationale
Deep vein thrombosis (DVT) can lead to pulmonary embolism but does not directly cause chest pain and shortness of breath.
Choice B rationale
Pulmonary embolus (PE) is characterized by chest pain, shortness of breath, and hemoptysis (coughing up blood), especially in patients on bed rest.
Choice C rationale
Anemia can cause fatigue and shortness of breath but not typically chest pain and hemoptysis.
Choice D rationale
Right heart failure can cause shortness of breath and edema but not typically chest pain and hemoptysis.

Correct Answer is A
Explanation
Choice A rationale
Decreasing coronary artery constriction by giving aspirin is a primary objective in managing unstable angina. Aspirin inhibits platelet aggregation, reducing the risk of clot formation and improving blood flow in the coronary arteries. This helps to alleviate chest pain and prevent myocardial infarction.
Choice B rationale
Increasing afterload for the left ventricle to maximize cardiac output is not a desirable objective in managing unstable angina. Increasing afterload would increase the workload on the heart, which is counterproductive in patients with angina. The goal is to reduce the heart’s workload and improve blood flow.
Choice C rationale
Increasing preload to reduce overall cardiac workload is not a primary objective in managing unstable angina. Increasing preload would increase the volume of blood returning to the heart, potentially worsening symptoms. The focus is on reducing myocardial oxygen demand and improving coronary perfusion.
Choice D rationale
Reducing arterial inflammation by administering statins is a long-term strategy for managing cardiovascular disease, but it is not the immediate objective in managing unstable angina.
Statins help to lower cholesterol levels and reduce inflammation, but the immediate goal in unstable angina is to relieve chest pain and prevent myocardial infarction.
Correct Answer is B
Explanation
Choice A rationale
Checking blood sugar levels before each meal is a good practice for managing diabetes and does not indicate a need for further teaching.
Choice B rationale
Skipping medication if blood sugar is normal indicates a misunderstanding of diabetes management. Medications should be taken as prescribed to maintain consistent blood sugar levels.
Choice C rationale
Following a balanced diet and exercising regularly are important components of diabetes management and do not indicate a need for further teaching.
Choice D rationale
Monitoring feet for cuts or sores is crucial for diabetes management to prevent complications like infections and ulcers.
