What type of angina is characterized by vasospasms of coronary arteries and causes unpredictable chest pain?
Prinzmetal or variant agina
Unstable angina
Angina pectoris
Stable angina
The Correct Answer is A
A. Prinzmetal or variant angina: Prinzmetal angina, also known as variant angina, is characterized by episodes of chest pain due to vasospasms of the coronary arteries. This type of angina can occur unpredictably, often at rest, and is associated with transient ischemia of the heart muscle.
B. Unstable angina: Unstable angina is characterized by sudden, unpredictable chest pain that occurs at rest or with minimal exertion and may last longer than stable angina. It indicates a significant risk of myocardial infarction but is not primarily caused by vasospasm.
C. Angina pectoris: Angina pectoris is a general term for chest pain due to ischemia, which can be stable or unstable. It does not specifically refer to the vasospasm that defines Prinzmetal angina.
D. Stable angina: Stable angina is characterized by predictable chest pain that occurs with exertion or stress and is relieved by rest or nitroglycerin. It is not associated with coronary artery vasospasms.

Correct Answer is ["C","D","E"]
Explanation
A. Expecting copious amounts of frothy, pink sputum: This symptom is typically associated with left-sided heart failure or pulmonary edema, where fluid accumulates in the lungs, leading to the production of frothy, pink sputum. It is not a classic manifestation of right-sided heart failure.
B. Fine crackles throughout both lung fields: Fine crackles are more indicative of left-sided heart failure due to fluid accumulation in the lungs (pulmonary congestion). In right-sided heart failure, the primary issues relate more to systemic congestion rather than pulmonary congestion.
C. +pitting edema in lower extremities: Right-sided heart failure often leads to fluid retention and peripheral edema due to increased venous pressure. Pitting edema in the lower extremities is a common clinical manifestation in patients with cor pulmonale and right-sided heart failure.
D. Altered level of consciousness: This can occur due to decreased cardiac output and resulting reduced cerebral perfusion. In right-sided heart failure, especially in advanced stages, fluid overload can lead to increased intracranial pressure, contributing to altered mental status.
E. Jugular vein distention: Jugular vein distention is a classic sign of right-sided heart failure. Increased pressure in the right atrium due to fluid overload results in distended neck veins, indicating elevated venous pressure.
Correct Answer is A
Explanation
A. Actually, people who have the latent form of the disease won't be sick and can't spread it either: This response is accurate because individuals with latent tuberculosis infection (LTBI) do not exhibit symptoms and are not infectious. They carry the bacteria in their body, but it remains dormant and does not spread to others. Only those with active tuberculosis disease are capable of transmitting the infection through respiratory droplets.
B. Many people do manage to fight off the infection, but you are right: they can still spread it by coughing or sneezing: This statement is misleading because it implies that individuals with LTBI can spread the disease, which is not the case. Only those with active TB are contagious.
C. There isn't any real risk of them spreading it, but we would like to vaccinate everyone who's had any contact with it in the past: This response downplays the importance of understanding the difference between latent and active TB and could create confusion. Vaccination for tuberculosis (BCG vaccine) is not routinely given in the United States, and exposure alone does not necessitate vaccination.
D. If someone has been previously exposed to tuberculosis, they are particularly infectious because they are often unaware of the disease: This statement is incorrect, as individuals who have been exposed but have LTBI are not infectious. It is only those with active TB who pose a risk of spreading the infection.
