Which of the following would not cause edema in the lungs?

• Increased pulmonary capillary constriction

• Left sided heart failure

• Increased pulmonary capillary permeability

• Blockage of pulmonary lymph vessels

Which of the following are associated with brisket edema in cattle?

• Increase in partial pressure of oxygen in the atmosphere

• Left sided heart failure

• Increased pulmonary capillary dilation

• Liver congestion & enlargement

A patient presents with a protein losing enteropathy. It’s albumin is level is extremely low and the patient has dependent edema. What is preventing further edema?

• Increase in capillary hydrostatic pressure

• Increase in plasma colloid osmotic pressure

• Increase in interstitial fluid hydrostatic pressure

• Increase in interstitial fluid colloid osmotic pressure

Vasoconstriction is caused by which of the following neurotransmitters released from the post ganglionic nerve terminals?

• Angiotensin 2

• Norepinephrine

• Acetylcholine

• Nitric oxide

A patient presents with hemorrhage after getting hit by a car. The gums are pale, skin is cold and pulse is high. What is happening systemically?

• There is decreased sympathetic activity to the heart

• There is increased sympathetic activity to the cutaneous vessels & mucosa

• There is increased parasympathetic activity to the cutaneous vessels & mucosa

• There is decreased epinephrine secretion from the adrenal medulla

Which of the following occurs during vasovagal syncope?

• Increased blood pressure & heart rate

• Increased sympathetic & decreased parasympathetic activity

• Decreased sympathetic & increased parasympathetic activity

• Vasoconstriction in splanchnic arteries

Which of the following events occur shortly after the T wave of the ECG?

• Isovolumetric relaxation

• Atrial contraction

• Rapid Ejection

• Isovolumetric contraction

If you administer an anti-hypertensive to block ACE. The decrease in blood pressure occurs due to which of the following?

• Vasodilation due to decreased kinins

• Vasoconstriction due to decrease in angiotensin 2

• Vasoconstriction due to increase in angiotensin 2

• Vasodilation due to decrease in angiotensin 2

What does the T-wave represent on an ECG?

• Atrial depolarization

• Atrial repolarization
