Question 1

A 23-year-old patient presents to the emergency department with high fever, chills, extreme fatigue, and arthralgias. Your physical examination reveals grade II heart murmur heard loudest over the fourth intercostal space left sternal border. The arms of the patient reveal past IV drug abuse. The clinician should recognize these are signs and symptoms of:

Accepted Answer

The combination of fever, chills, fatigue, arthralgias, a heart murmur, and a history of IV drug abuse strongly suggests bacterial endocarditis, a condition where the inner lining of the heart valves becomes infected.

Question 2

After multiple pregnancies, the following vascular disorder is common:

Accepted Answer

Varicose veins are common after multiple pregnancies due to the increased pressure in the veins of the lower body. Pregnancy increases the volume of blood in a woman's body, but decreases the flow of blood from the legs to the pelvis. This change supports the growing fetus but can also result in enlarged veins in the legs.

Question 3

A 75-year-old patient complains of pain and paresthesias in the right foot that worsens with exercise and is relieved by rest. On physical examination, you note pallor of the right foot, capillary refill of 4 seconds in the right foot, +1 dorsalis pedis pulse in the right foot, and +2 pulse in left foot. Which of the following is a likely cause of the signs and symptoms?

Accepted Answer

The symptoms of pain and paresthesias in the foot that worsen with exercise and are relieved by rest, along with physical findings of pallor, delayed capillary refill, and reduced pulse strength in the affected foot, are indicative of arterial insufficiency. These findings suggest compromised arterial blood flow to the affected limb.

Question 4

Your patient complains of worsening ankle edema and weight gain over the last week. On physical examination, you note jugular venous distension, ascites, hepatomegaly, and splenomegaly. These conditions are indicative of:

Accepted Answer

The symptoms described, including ankle edema, jugular venous distension, ascites, hepatomegaly, and splenomegaly, are indicative of right ventricular failure. These symptoms are related to systemic congestion due to the heart's inability to pump blood effectively from the systemic circulation into the pulmonary circulation.

Question 5

The target body mass index for women is:

Accepted Answer

The answer of The target body mass index for women...

Question 6

The murmur of a ventricular septal defect occurs when the ventricle contracts and blood flows from the left ventricle into the right ventricle. This creates a ____________ heart murmur.

Accepted Answer

The murmur of a ventricular septal defect is holosystolic (or pansystolic), occurring throughout the entire systole as blood flows from the higher pressure left ventricle to the lower pressure right ventricle.

Question 7

Which of the following conditions is/are part of metabolic syndrome?

Accepted Answer

Metabolic syndrome is characterized by a cluster of conditions that occur together, increasing the risk of heart disease, stroke, and type 2 diabetes. These conditions include increased blood pressure (hypertension), high blood sugar (often indicating insulin resistance), excess body fat around the waist, and abnormal cholesterol or triglyceride levels (hyperlipidemia). Therefore, all of the options listed are part of metabolic syndrome.

Question 8

Your patient complains of a feeling of heaviness in the lower legs daily. You note varicosities, edema, and dusky color of both ankles and feet. Which of the following is the most likely cause for these symptoms?

Accepted Answer

The symptoms described, including a feeling of heaviness in the lower legs, varicosities, edema, and a dusky color of the ankles and feet, are characteristic of venous insufficiency. This condition occurs when the veins have problems sending blood from the limbs back to the heart, leading to blood pooling in the legs.

Question 9

Your patient has had hypertension for 10 years, a myocardial infarction 5 years ago, and now complains of dyspnea on exertion, cough, and three-pillow orthopnea. Which of the following conditions is likely?

Accepted Answer

The symptoms described, including dyspnea on exertion, cough, and three-pillow orthopnea, are indicative of left ventricular failure. These symptoms suggest a decrease in the left ventricular function, leading to pulmonary congestion and the clinical manifestations of heart failure.

Question 10

A patient with significant aortic stenosis often suffers from:

Accepted Answer

Aortic stenosis leads to increased pressure in the left ventricle, causing left ventricular hypertrophy and eventually left-sided heart failure.

Question 11

A patient with hypertension who has hyperlipidemia should aim for an LDL measurement of:

Accepted Answer

Patients with hypertension and hyperlipidemia should aim for an LDL cholesterol level of 100 mg/dL or less, as this can help reduce the risk of cardiovascular events.

Question 12

When an examiner presses on the liver and elicits hepato-jugular reflux, which of the following conditions is likely?

Accepted Answer

Hepatojugular reflux is a positive test for right ventricular failure.

Question 13

An atrial septal defect (ASD) causes a left to right shunt, which enlarges the right atrium. Because of this effect, which of the following conditions often occur with ASD?

Accepted Answer

Atrial septal defect (ASD) can lead to enlargement of the right atrium due to the increased volume of blood that needs to be handled. This enlargement can predispose individuals to atrial fibrillation due to the stretching and remodeling of the atrial tissue. Additionally, the increased blood volume in the right side of the heart can lead to increased pressure in the venous system, manifesting as jugular venous distension. Asthma is a respiratory condition and is not directly related to the hemodynamic changes caused by ASD.

Question 14

Your 47-year-old female patient has a waist to hip ratio of 0.1. In terms of cardiovascular disease risk, this is considered:

Accepted Answer

The answer of Your 47-year-old female patient has a waist...

Question 15

Dyspnea, cough, and pulmonary crackles are symptoms that can occur in left ventricular failure and respiratory disorders, such as pneumonia. Which of the blood tests below can be used to differentiate cardiovascular from pulmonary disease?

Accepted Answer

Brain Natriuretic Peptide (BNP) levels are elevated in heart failure due to the stretching of heart chambers, which is not a direct response to respiratory diseases like pneumonia, making it useful for differentiating between cardiac and pulmonary causes of symptoms like dyspnea.

Question 16

Aortic regurgitation occurs after S₂ during ___________________ because there is turbulent flow that refluxes into the left ventricle after the aortic valve closes.

Accepted Answer

Aortic regurgitation occurs during early diastole because this is when the aortic valve closes and the pressure in the aorta exceeds that in the left ventricle, causing blood to flow back into the ventricle.
