98. You are assessing a patient and identify a thrill while examining the carotid pulse. Which of the following conditions would be MOST consistent with this assessment finding? ? An increase in cerebral blood flow. ? A partial occlusion of the carotid artery. ? An increase in left ventricular pressure. ? An increase in right ventricular pressure.

You are working in a cardiac unit and are tasked to determine the percentage of blockage in a patient's carotid artery. For this patient, you know the average blood velocity for a non blocked artery is 20 cm/s. Using the Doppler Ultrasound, you measure the blood velocity in your patient to be 42 cm/s at the fastest position along the carotid artery. About what percent of the patient's artery is blocked? Note: In this procedure, the patient is lying flat, meaning there is no change in height of the artery. Also, do not include the percent sign in your actual answer. If you do, your answer will be counted wrong. Hint: Suppose A2/A1 = 1/5 (for example) where A2 is the cross sectional area of the blockage and A1 is the area outside the blockage. This would mean that the blockage leaves only 20% (0.2) of the artery open. Or, that the artery itself is 100%-20% = 80% blocked.

A 25-year-old male IV drug user presents with a 3-week history of worsening lethargy and confusion. On examination, his pulse rate is 130bpm, and his blood pressure is 120/80 mmHg. Cardiovascular examination reveals raised JVP with large v-waves and a loud systolic murmur. A palpable, pulsatile liver is felt when the hepato-jugular reflex is attempted. What type of murmur is most fitting with this patient's presentation?Choose the most suitable option A.Functional murmur B.Tricuspid stenosis C.Pulmonary stenosis D.Tricuspid regurgitation.

For this patient, you know the average blood velocity for a non-blocked artery is 20 cm/s.
