When talking about hypertension, we know that it can physiologically be caused by all of the following except

Increase peripheral resistance

Decrease in cardiac output

Both increased cardiac output and peripheral resistance

Increased cardiac output

Answer and Explanation

The Correct Answer is B

A. Increase peripheral resistance: An increase in peripheral resistance contributes to hypertension by raising the pressure in the arteries. This condition often results from vasoconstriction or structural changes in the blood vessels, leading to higher overall blood pressure.

B. Decrease in cardiac output: A decrease in cardiac output typically does not cause hypertension. In fact, low cardiac output may lead to hypotension (low blood pressure) since there is less blood being pumped into the circulatory system. This option is the exception when discussing physiological causes of hypertension.

C. Both increased cardiac output and peripheral resistance: Both increased cardiac output and peripheral resistance can lead to hypertension. An increase in either factor can elevate blood pressure, and their combined effect can significantly contribute to the development of hypertension.

D. Increased cardiac output: Increased cardiac output raises blood pressure by delivering more blood to the arteries with each heartbeat. This can occur due to various factors such as increased fluid volume, increased heart rate, or heightened contractility of the heart.

Correct Answer is A

Explanation

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.

A. Pneumonia B. Heart failure C. Pulmonary emboli D. Acute pulmonary edema

Correct Answer is A

Explanation

A. Pneumonia: Pneumonia is a common cause of acute respiratory distress syndrome (ARDS) and is associated with significant inflammation and alveolar damage. Assessing for pneumonia is a priority as it can exacerbate ARDS and lead to further respiratory compromise. Early identification and treatment of pneumonia can significantly improve the patient's outcome.

B. Heart failure: While heart failure can contribute to respiratory distress, ARDS is primarily a non-cardiogenic condition. Assessing for heart failure is important, but pneumonia is more directly linked to the development of ARDS and should be prioritized.

C. Pulmonary emboli: Although pulmonary embolism can cause acute respiratory distress, it is not the primary concern when dealing with ARDS. Assessing for embolism is important, but pneumonia is a more common and immediate concern in the context of ARDS.

D. Acute pulmonary edema: Acute pulmonary edema is usually associated with cardiac issues and is not the underlying cause of ARDS. While monitoring for pulmonary edema is necessary, pneumonia is the more relevant condition to assess in a patient diagnosed with ARDS.
